SYSTEM DESCRIPTION
The Viking ESFR “Pre-Primed Single Interlocked Preaction” Cold Storage System is a
fixed fire protection system designed for installation in refrigerated or cold warehouse
storage applications. This system is also appropriate for unheated storage applications
in areas subject to freezing. This is a pre-primed preaction system with electric release
that utilizes a deluge valve with conventional and electric release trims. The riser
consists of two Viking Model F-1 Easy RiserTM Swing Check Valves, one with special
cold trim and the second with by-pass trim to isolate the antifreeze in the system from
the water supply. The sprinkler system piping is filled with low-pressure propylene glycol
and water solution to supervise and pre-charge the discharge system and eliminate air
pockets for more efficient system performance. The additional Easy RiserTM Check Valve
is installed above the main check valve and is required to prevent thermal transfer of
cold antifreeze from the freezer area onto the clapper surface of the primary check valve
and minimize frost on the riser assembly. The pressure in the system is maintained by
the CS-1 tank and pressure pump system that controls and maintains the desired
solution pressure above the primary check valve. The detection system shall be capable
of operation prior to or equal to an ESFR Sprinkler having an RTI (Response Time
Index) of 50 or less. No linear detection shall be allowed. This limits the system to low
temp spot heat, beam smoke or air sample type smoke system or equal.
Upon operation of the detection system the deluge valve opens prior to sprinkler
operation and pressurizes the sprinkler piping to the desired discharge pressure. Upon
operation of the sprinkler(s), the pressurized propylene glycol/water solution is
distributed from the sprinkler. Water from the supply system pushes out the propylene
glycol/water solution at a very rapid rate due to the sprinkler orifice size and design
pressures. The limited system volume ensures that 100% water will flow from the
sprinklers at an appropriate stage of fire development.
The CS-1 Tank and Pump System is designed to maintain supervisory system static
pressure in the sprinkler piping using antifreeze and water premix. As the system
operates, an alarm pressure switch is used to send a signal to the CS-1 system control
to shut off the flow of antifreeze from the reservoir. Upon operation of the detection
system, the deluge valve opens and pressurizes the system to desired starting
discharge pressure. An alarm is activated due to water flow from the alarm pressure
switch on the preaction trim. When the ESFR Sprinkler(s) operate the system is already
pressurized and will discharge the antifreeze solution followed by water. Typically, only
those sprinklers above or adjacent to the fire operate, minimizing water damage and
contamination. Other antifreeze systems within the warehouse would not typically be
activated.
In the event of a broken sprinkler or sprinkler pipe without a fire condition, the deluge
valve will hold back the water supply and only antifreeze will be drained from the
sprinkler or broken pipe. This will prevent large amounts of water from being discharged
and possible contamination of the antifreeze left in the system that could cause
undesired freezing in the piping. A pressure supervisory switch on the antifreeze system
located at the primary Easy RiserTM Check Valve adjacent to the deluge valve will
provide an alarm of low-pressure condition. The antifreeze supply from the CS-1 pump
must be manually shut off in this condition at the riser supply point.
7
In the event of a fire, the system pressure supervisory switch that controls the pump unit
is wired through the alarm switch located on the deluge valve and to the CS-1 pump unit.
In this case, the CS-1 pump solenoid valve is restricted from opening for the riser that is
flowing to the fire area and stops the flow of antifreeze to the discharging system.
In order to effectively apply 100% water as rapidly as possible, the system size must be
limited in volume. Full-scale fire testing of the 50% propylene glycol and water premix
solution and a system volume of 1,100 gallons (4 163 liters) has been performed
successfully at Underwriters Laboratories Inc., resulting in UL Listing of the ESFR
VK510 Sprinkler for use with 35% or 50% propylene glycol and water solution. The
system uses either a 35% or 50% (depending on the minimum temperature in the area
being protected) by volume mixture of propylene glycol and water premix solution.
The propylene glycol and water mixture cools and adds wetting ability to control the fire
until water is applied to suppress the fire. The area of coverage for a single system is
dependent upon the volume of the system required to cover the area being protected.
The hydraulic calculations are necessary in order to properly size the system piping.
For refrigerated area systems, the piping system shall be pitched to drain complete
system toward the riser and Easy RiserTM Check Valves with branch lines at ½” per 10
ft. (4 mm/m) and mains at ½” per 10 ft. (4 mm/m) run of pipe. For systems in unheated
areas subject to freezing, branch lines shall be pitched at ½” per 10 ft. (4 mm/m) and
mains at ¼” per 10 ft. (2 mm/m) run of pipe.
This system shall be designed by qualified fire protection technicians, in conjunction with
requirements of the Authorities Having Jurisdiction. Viking ESFR Cold Storage Systems
are designed to meet the UL Listing requirements described in Viking technical data for
ESFR K25.2 Sprinkler VK510 for use with 35% or 50% propylene glycol and water
solution, and the standards of NFPA 13 or other organizations, and also with the
provisions of governmental codes, ordinances, and standards where applicable. This
system shall meet all requirements of ESFR installations except where specified in this
owner's manual. This system can be considered a wet system due to the system being
filled with the approved antifreeze solution, and operation of the detection and preaction
system will provide water supply and pressurized solution at the sprinkler upon
operation.
When using this system, ceiling-only sprinklers are required and no in-rack sprinklers are
needed. The following storage configurations are required:
-
Single-row, double-row, and multiple-row rack storage is required and
sprinklers shall be located in accordance with applicable Viking technical
data and the latest recognized storage installation rules of NFPA or the
Authority Having Jurisdiction (AHJ).
-
Open rack storage is required, and sprinklers shall be located in
accordance with applicable Viking technical data (refer to the latest
issue of sprinkler data page 46 a-c) and the latest recognized storage
installation rules of NFPA or the Authority Having Jurisdiction (AHJ).

a viscosity of 200 centipoise, as opposed to water at 1 centipoise at 70 °F (21.1
°C). Two sets of hydraulic calculations will be required for the system piping; one
utilizing Hazen-Williams method of determining friction loss, and one utilizing
Darcy-Weisbach method of determining friction loss. The Hazen-Williams friction
loss factors will be utilized for flowing water through the piping, the DarcyWeisbach friction loss factors will be utilized for flowing propylene glycol/water
solution through the system piping at the lowest operating temperature.
The information in Table 1 is provided for Firefighter Eliminator F 50% propylene
glycol/water pre-mix solution, while the information in Table 2 is provided for
Firefighter Eliminator C 35% propylene glycol/water pre-mix solution.

PRE-PRIMED SINGLE INTERLOCKED PREACTION SYSTEM FOR COLD
STORAGE
The Viking “Pre-Primed Single Interlocked Preaction” Cold Storage System is electrically
operated using a listed releasing control panel, listed detection system as described in
the technical data, and a listed Viking single interlocked preaction assembly, two Viking
Easy RiserTM Check Valves. The first or primary Easy RiserTM Check Valve and trim
includes connections for antifreeze supply from the Viking Model CS-1 pump control
assembly that also includes a reservoir for antifreeze and controls. A pressure switch to
control the supervisory antifreeze pressure is also included. The antifreeze must fill the
system less any air pockets in order to prevent water from entering cold storage area
and contaminating the antifreeze mixture, which could cause freezing. A Viking
automatic air vent assembly (Model AV-1) is recommended for installation at the end of
all branch lines and high points of the supply mains. A second Easy RiserTM Check
Valve that includes a system main drain and a by-pass line is installed approximately 5
to 10 ft (1,5 to 3,0 m) above or downstream of the first check valve between the freezer
wall and the primary check valve. This valve is required to protect the riser assembly and
clapper of the first check valve from freezing due to hydrodynamic thermal transfer of
cold antifreeze from the freezer to the riser check valve. The by-pass line is required to
allow all system controls on the primary check valve to function properly. This valve also
helps to minimize insulation and heat trace requirements to the riser system outside of
the freezer.
•
The single interlocked preaction control valve assembly is a standard Viking
Model E-1 or F-1 Deluge Valve including Conventional Deluge Trim with Electric
Release. This valve controls the supply water to the system having a static
supply pressure capable of supplying adequate starting pressure of the most
11
remote sprinklers as calculated. The operation of the control valve is caused by
the operation of the detection system after sensing a fire condition. The
installation position must be directly adjacent and at the bottom of the supply
riser to the area of protection and must be in a heated room that maintains a
minimum temperature of 40 °F (4 °C).
5.0
•
The primary Easy RiserTM Check Valve is a Viking Model F-1 that includes a
system main drain, inlet connection for antifreeze supply, system pressure
switch, system supervisory switch and gauges to monitor system antifreeze
pressure and control the CS-1 antifreeze pump system. This check valve must
be located downstream of the deluge valve (within 1 to 2 ft maximum). It is
recommended to install this check valve as close to floor level as convenient in
order to properly maintain the valve. The inlet side of valve is atmospheric air,
while the outlet will be the desired static antifreeze pressure to the system.
Options for the check valve include pressure relief valve (see selection below)
and automatic pressure control system for variable temperature freezers and
coolers described below.
•
A second thermal isolation valve (Viking Model F-1 Easy RiserTM Swing Check
Valve) is installed as close to the freezer wall as possible but at least 5 ft above
or downstream of the primary check valve within the heated area of the riser
room to prevent thermal migration of the antifreeze from the freezer and protect
the primary check valve from freezing near the atmospheric air surface of the
clapper and seat. This valve includes a main drain and a special 3/8” I.D. copper
tube by-pass to allow proper system pressure monitoring and prevent thermal
migration to primary check valve. The main drain must be piped to the main drain
of the primary check valve and returned to the recovery tank.
•
Releasing control panel shall be a listed releasing panel capable of single hazard
and two-zone operation. The control panel shall be provided with a 90-hour
backup battery supply. Zone 1 shall operate the releasing circuit and alarm. Zone
2 shall detect low pressure antifreeze and provide alarm.
•
Detection is required for this system. The detection system shall be capable of
operation prior to or equal to an ESFR Sprinkler having an RTI (Response Time
Index) of 50 or less. No linear detection shall be allowed. This limits the system
to low temp spot heat, beam smoke or air sample type smoke system or equal.
SYSTEM INSTALLATION REQUIREMENTS AND CONSIDERATIONS
5.1
Tree Configuration - ESFR Cold Storage System
A tree type piping configuration is required for this type system over the grid type
system because this type of system is easier to set up for drainage. Also, with a
center feed main supplying branch lines, the flow is directed toward the first open
sprinklers. This allows the antifreeze solution to be expelled from lines and mains
leading directly to open sprinklers and to be replaced with 100% water much
faster than in grid type systems. For tree systems utilizing this system, the mains
12
or lines should not be looped together as done in some dry pipe and preaction
systems.
Tree Sprinkler System: A system of dead-end branch lines centrally fed by a
cross main.
The discharge pressure for all sprinklers flowing must maintain at a minimum of
the required design.
The 1,100 gallon (4,163 liter) system volume is established by adding the piping
volume from the remote area to the top of the Easy RiserTM Check Valve at the
base of the riser. The actual propylene glycol solution requirement for the system
is determined by adding all the system piping volume together.
All NFPA 13 installation criteria and AHJ requirements apply to installation of the
Viking ESFR Cold Storage System with the following exceptions:
•
•
•
•
Commodity limited to Class II or less (limited to wood pallets).
Maximum ceiling height to bottom of inside upper deck is 40 ft. (12,2 m) with
a maximum storage height of 35 ft. (10,7 m) and a minimum sprinkler
discharge pressure of 40 PSI (278 kPa). OR:
Maximum ceiling height to bottom of inside upper deck is 45 ft-3 in. (13,8 m)
with maximum storage height of 40 ft. (12,2 m) and a minimum sprinkler
discharge pressure of 60 PSI (414 kPa).
Where the minimum temperature in the area being protected is 8 °F (-13.3
°C) or above, 35% percent by volume of propylene glycol factory premixed
with water must be used. Viking requires Firefighter Eliminator C premix 35%
propylene glycol/water mixture with a freeze temperature rating (freeze point)
of 2.4 °F (-16.4 °C). OR:
13
•
•
•
•
•
•
•
Where the minimum temperature in the area being protected is between 8 °F
(-13.3 °C) and -21 °F (-29.4 °C), the percentage by volume of propylene
glycol must be 50%, factory premixed with water for antifreeze solution.
Viking requires Firefighter Eliminator F type 50% propylene glycol/water
mixture, with a freeze temperature rating (freeze point) of -26 °F (-32.2 °C).
Minimum ambient temperature is -21 °F (-29.4 °C). NOTE: The minimum
temperature is NOT an average in the freezer, but is the lowest temperature
for the system.
Maximum system volume is 1,100 gallons (4 163 liters). Refer to calculation
to determine volume.
Use ordinary temperature rated 165 °F (74 °C) Viking ESFR K25.2 Sprinkler
VK510. Exception: Intermediate temperature rated 205 °F (96 °C) Viking
ESFR VK510 K25.2 Sprinklers that are intended for installation in close
proximity to heat sources may be applied only as referenced in NFPA 13.
The piping system must be pitched for drainage of the system after operation.
For refrigerated area systems, the piping system shall be pitched to drain
complete system toward the riser and alarm valve with branch lines at ½” per
10 ft. (4 mm/m) and mains at ½” per 10 ft. (4 mm/m) run of pipe. For systems
in unheated areas subject to freezing, branch lines shall be pitched at ½” per
10 ft. (4 mm/m) and mains at ¼” per 10 ft. (2 mm/m) run of pipe.
The system must be designed so maximum operating pressure of the system
does not exceed 175 PSI (1 207 kPa) at the sprinkler, including test
pressures of pumps at zero flow.
Detection System shall be capable of operation prior to or equal to an ESFR
Sprinkler having an RTI (Response Time Index) of 50 or less. No linear
detection shall be allowed. This limits the system to low temp spot heat,
beam smoke or air sample type smoke system or equal.
5.1.1
Piping System to Sprinklers
Tree type piping configurations vary. There are side or end feeds, offset
feeds, and center feeds. Many times the configuration of the tree system
piping is dictated by building features or by hydraulic calculations.
The maximum system volume must be maintained and is calculated at a
maximum from the primary Easy RiserTM Check Valve, including all piping
to the remote sprinklers (refer to calculation to determine volume).
The deluge valve and trim system, system check valves along with all
antifreeze and supply piping, must be installed in a heated area that is
maintained at or above 40 °F (4 °C). Insulating the fire sprinkler riser will
be required to eliminate condensation and frost from developing on the
piping in the heated area. Insulate the riser main from the freezer wall to
the isolation check valve. If the primary system check valve is close
enough to isolation check valve [less than the 5 ft (1,5 m) recommended]
and freezer separation wall to cause freezing of water and condensation
on piping below the check valve, then a listed heat trace heating system
may be required for the riser piping above and below the primary check
valve that will maintain a temperature under the insulation of 70 °F (21.1
°C) to eliminate condensation and maintain internal temperature of
14
solution above freezing for air below the primary check valve. Due to
difficulty in servicing and insulating the check valve, it is recommended to
install the deluge and check valve near floor level at the base of the main
riser in the heated area allowing approximately 1 to 2 ft between the
outlet of deluge valve and inlet of the primary Easy RiserTM Check Valve
and install the maximum length of pipe from the primary Easy RiserTM
Check Valve to the Isolation check valve that is between the freezer wall
and the primary check valve.
Air vent valves or manual bleed valves must be installed at the highest
and most remote points on the tree piping system in order to vent out all
air during fill of the 35% or 50% premix of propylene glycol/water solution
in the system. Additional vent or bleed valves shall be installed on the end
of each branch line at high points and feed mains at high points to ensure
air is vented from the system. This is required in order to eliminate
compressible gas (air) from the system when setting supervisory pressure
from the antifreeze CS-1 pump system. Also, the manual vent valves may
be used for multiple sample points of the system for quality testing of the
antifreeze solution. The Viking Model AV-1 Automatic Air/Vent Valve is
recommended for this use. It automatically vents air during fill and breaks
the vacuum for faster drainage of the system when performing
maintenance or draining the system after operation.
AV-1 Air Vent Assembly
5.1.1.1
General Piping and Material Recommendations
•
In order to prevent leaks and preserve the antifreeze
solution, it is imperative that grooved pipe ends are smooth,
round, and free of burrs, flat spots, and weld seam
15
imperfections. Also, pipes should be capped to prevent
contaminant during shipping, storage, etc.
5.1.2
•
Antifreeze solution is very lubrise and difficult to seal
compared to plain water and initial care in pipe connections
will minimize leaks at start-up. Also, antifreeze solution will
prevent microbiological attack to piping material 5 times
greater than water. Cleanliness is required to improve
longevity of solution. Prefabricated pipe should be capped
during shipping and staging prior to installation.
•
If grooved couplings are utilized in the system piping
installation, "flush seal" gaskets, low temperature EPDM
rubber and lube are required. Pooling of propylene glycol in
the system shall be eliminated. Vent valves shall be
minimum ½” ball valves with ½” plug. Vent valves can
double as solution test points as well; the Viking Model AV-1
Air/Vent Valve is recommended, as it includes strainer and
test connection for automatic venting during fill and drain of
the system. Material installed on the system shall be
compatible with propylene glycol solution. A re-claim tank
with adequate capacity of the largest system(s) shall be
located near the system riser(s). System drain piping shall
be arranged to discharge to the re-claim tank.
Primary Check Valve Main Drain
The main drain outlet should be
directed
to
an
appropriate
location, and the drain valve shall
be installed at an accessible level
so it can be operated from the
floor level. Installing the isolation
Easy RiserTM Check valve at an
elevation near the horizontal
mains supplying the system and
10 to 15 ft (3,0 to 4,5 m) above the
primary check valve will reduce the cold thermal transfer of propylene
glycol solution in the system piping to the vertical system riser and
minimize frosting on the system riser.
The main drain valves from the isolation check and primary check valves
shall be installed at an accessible level, as the solution will be trapped in
the drop leg to the drain valve and will not affect the total calculation for
the system. The main drain valve will be used to drain the system piping
downstream of the Easy RiserTM Check Valves. As the cold antifreeze
from the freezer area will emit cold thermal transfer, it will be required to
insulate the drain pipe to prevent frosting.
16
Propylene glycol/water solutions are designed to be installed on systems
supplied by potable water supplies. Local authorities should be consulted
prior to draining system to storm sewers or to natural drainage areas. In
the main drain line between the valve and Easy RiserTM Check Valves
inlet, a tee is provided on the check valve trim with a 1” NPT connection
for supply and maintenance of the antifreeze solution to the system above
the primary Easy RiserTM Check Valve.
5.1.3
Reclaim Tank
An atmospheric storage tank is to be installed for
the system(s) that is of adequate capacity of the
largest system volume installed. The tank shall be
utilized as a reclaim tank for the propylene glycol
solution in the system piping when the system(s)
are drained for system service and for discharge
of propylene glycol solution if system pressure
exceeds 175 PSI (1 207 kPa) at the sprinklers.
The ball valve must be shut before the switch on
the CS-1 Panel is placed in Automatic Mode.
5.1.4
Example
Automatic Pressure Control System
A means of relieving system pressure due to pressure buildup can be
provided through a specialized pressure switch and solenoid valve on the
downstream side of the primary check valve. See data page 47 a-b.
Storage areas that are expected to fluctuate more than 10 degrees from
nominal temperature will experience increased pressure in the system
17
piping due to expansion of the propylene glycol when the temperature
rises in the storage area.
In order to prevent the pressure relief valve (PRV) on the Easy RiserTM
valve trim from operating, the pressure control system is set to maintain
pressure below the set point of the PRV and above the system
maintenance pressure. The alarm pressure switch will prevent the APCS
from operating when the deluge valve has operated.
Prior to installation of system, maximum temperature changes are
required to be considered to determine possible expansion and
contraction rate of propylene glycol solution. If the contraction rate is
greater than the storage tank that accompanies excess pressure pump,
an additional supply tank to supplement excess pressure pump shall be
installed.
5.1.5
Solution Test Valves
Multiple propylene glycol/water solution test valves are to be installed on
the system piping for semi-annual testing with a refractometer. The
testing stated in this section is more restrictive than the required test
frequency indicated in NFPA 25. Solution test valves should be located in
several areas of the system piping:
• The most practical location immediately downstream of the primary
Easy RiserTM check valve.
• The most remote location from the Easy RiserTM check valve.
• One valve located at the end of 50% of the line piping directly on the
Model AV-1 Air/Vent Valve assembly.
• A test valve shall be located at the end of the nearest line on the tree
system and the last line on the tree system.
If the propylene glycol/water solution becomes diluted or does not pass
the refractometer test, the entire system is to be drained. All sections of
trapped piping are to be drained. Five percent (5%) of the pendent ESFR
sprinklers are to be removed and inspected for frozen solution.
If any of the pendent ESFR sprinklers are found with frozen solution, then
all the pendent ESFR sprinklers are to be removed and replaced with new
Viking K25.2 Pendent ESFR VK510 Sprinklers prior to re-charging the
system with new 35% or 50% premix propylene glycol/water solution. If
the 5% of removed sprinklers are not damaged, they can be re-installed
in the system. (Refer to the system service schedule for additional
solution tests.)
Sampling shall be taken from multiple points within the freezer system.
Ensure that the CS-1 pump antifreeze supply control system is returned
to the fully pressurized state once fluid sampling is completed. Antifreeze
solution shall be checked semi-annually with a refractometer to detect the
concentration of antifreeze solution and effectiveness against freezing.

5.1.6
Re-Charging System Piping with 35% or 50% Premix Propylene
Glycol/Water Solution
A suitable portable pump can be utilized to fill the system. The CS-1
pump can be used for filling the system initially at 15 GPM (56 l/min) to
100 ft. head pressure or system static pressure, however, it is a less
efficient pump for filling the system because of the duration of time
required to do so.
The CS-1 pump is to be utilized to bring the antifreeze solution to
maintenance pressure above the Easy RiserTM check valve, [normally 50
PSI (345 kPa)] and is designed to maintain system pressure once the
system is initially filled. Also, repeat air bleed from the system as
described above. If using the Viking Model AV-1 Air/Vent Valve assembly,
the air will automatically be vented during the fill cycle.
5.1.7
Expansion of Antifreeze in the System
In a freezer system, the atmospheric temperature is typically controlled at
a pre-determined desired temperature year round. The most likely time
over-pressurization of the system might occur due to temperature
fluctuation is in a warm-up mode of the freezer, which is very rare once it
is put into service. Also, variation in system pressure due to temperature
differential can be substantial.
When filling the system with antifreeze solution, all air must be bled from
the system in order to make final and maintained antifreeze solution
pressure non-compressible.
The proper relief valve setting shall be selected at 125% above the
maximum water supply pressure at the PRV location for constant
temperature freezers or coolers. This valve is required to protect the
sprinklers from over-pressurization.
At the sprinklers, the maximum of 175 PSI (1 207 kPa) is required, at the
ceiling location. This valve must be directed to a proper drain location, as
it is an automatic valve and will operate without warning.
Pressure relief valves operate at 90-105% of design set
pressure and close at 80% or greater than design set pressure.
The pressure relief valve set pressure must be at least 125% of
the maximum water supply pressure at inlet of the primary
check valve in order to not allow operation other than to protect
the sprinklers of system at 175 PSI (12 bar).
19
For freezers or coolers that
fluctuate in temperature, an
automatic pressure control
system is required that utilizes
a special DIGITAL pressure
switch and solenoid valve that
allows antifreeze to be relieved
back into the CS-1 or reclaim
tank. Calculation of volume
fluctuation of the largest system
where multiple systems are
installed must be made in order
to make sure the tank volume
of antifreeze supply is large
enough to contain the volume differential. The APCS set point shall be at
least 5 PSI (34,5 kPa) greater than the maximum static or residual
supervisory pressure of the system. The PRV will be utilized as a safety
backup to the pressure control system in case of power loss and nonpresence of backup power system to the freezer temperature control
system.
If the pressure should increase due to warm-up above the rated static
pressure of the system, the pressure relief valve or automatic control
system will bleed off antifreeze solution and maintain the maximum
pressure of 175 PSI (1 207 kPa) or below at the sprinkler. It is
recommended to fill the system with antifreeze after the freezer is at the
sustained set temperature. Or, cool the antifreeze solution in the freezer
area and then add it to the system. This will allow the piping system to
establish a normal ambient temperature when filling the system with
antifreeze. Slight warming will occur during the fill process. Another option
is to fill the system while warm. Monitor tank level and add more solution
as needed as temperature cools.

The purpose the antifreeze pressure pump is to lock in a supervisory
pressure in the system and eliminate air for proper performance of the
system. The CS-1 pump utilized on the ESFR Cold Storage System
provides a static pressure on the propylene glycol/water solution in the
system by taking suction from an atmospheric storage tank with premix
propylene glycol and water solution and discharging to the downstream or
system side of the primary Easy RiserTM check valve clapper.
Antifreeze solution pressure shall be maintained at a minimum of 50 PSI
(345 kPa). This maintenance pressure is applied by the antifreeze pump
system in order to eliminate air pockets and prevent water from migrating
into the system antifreeze in the event of an accidental operation of the
deluge valve. This is why it is important to eliminate all air from the
system. If air is present, it can compress to allow water into the system,
reducing the desired percentage (concentration) of propylene glycol in the
solution, thus increasing the risk of localized freezing. Also by eliminating
air pockets, the extended life of the antifreeze solution and possible
corrosion of system piping is minimized.
A supervisory pressure switch shall be located on the
system side of the primary Easy RiserTM check valve or
directly adjacent to the system inlet that monitors the
antifreeze solution pressure and signals the CS-1 pump
to maintain pressure in the proper range. The CS-1
pump provides a 5 GPM (18,9 l/min) flow at a minimum
of 50 PSI (345 kPa) pressure. The supervisory pressure
switch is included in the Easy Riser Check Valve Cold Storage Trim for
Preprimed Preaction Systems.
Where a single system is present, a reserve tank with a minimum size of
65 gallons (246 liters) constructed of cross-linked polyethylene shall be
utilized for the storage of propylene glycol/water solution to supply the
CS-1 pump. The tank is equipped with a fluid level indicator, and an
internal low fluid level indicator that shuts off the pump and gives a
supervisory alarm of low fluid level. The tank is fitted with a
pressure/vacuum vent valve.
If a single system is installed in a storage area that is subject to varying
temperature changes, the system design shall determine the maximum
expansion and contraction rate of the propylene glycol solution to
establish if an additional supply tank is required to be added to the
reserve tank and excess pressure pump. This applies when using the
automatic pressure control system that is piped from the riser back into
the CS-1 tank.
Where multiple systems are supplied from a single CS-1 pump, a reserve
tank with a minimum size of 160 gallons (606 liters) constructed of crosslinked polyethylene shall be utilized for the storage of premix propylene
glycol/water solution to supply the CS-1 pump.
21
Where multiple riser systems exist, the antifreeze solution system can be
supplied to multiple risers from a single pump system and the pressure
switch for each system must be controlled through the pump system
control panel. When the pressure drops below set point, a solenoid valve
supplied from the CS-1 pump shall open to allow flow of antifreeze
solution into the system(s) that are low on pressure. When pressure is
established, the solenoid valve will shut off.
Where multiple systems are supplied from a single CS-1 pump and a
single system operates due to water flow from open sprinkler, the control
panel is signaled by the alarm or flow switch of operating riser and shuts
off the supply solenoid to that riser. The remaining systems maintain
supervisory pressure. This prevents contamination of antifreeze solution
with water during operation of a single system and eliminates air pockets
that may contaminate antifreeze solution or cause pipe corrosion.
5.1.9
Propylene Glycol and Water Solution Premix
Premix 35% or 50% propylene glycol and water solution that is certified
by the manufacturer or a third-party agency is to be installed in the
system piping. Field mixing of propylene glycol and site water is
strictly prohibited, as the control of the mixture cannot be assured.
Firefighter Eliminator C 35% premix solution or Firefighter Eliminator F
50% premix solution (refer to data pages 49 a-b and 50 a-b) are required
by Viking, as they are mixed in the proper proportion and were utilized for
the research fire tests. Firefighter Eliminator C and Firefighter Eliminator
F include corrosion inhibitors and de-ionized water to prevent the
minerals in site water from reacting with the corrosion inhibitors.
This extends the usable life of the propylene glycol/water solution.
Improper field mixing of solution can result in reduced capability to
prevent freezing or to control a fire. The corrosion inhibitors included in
the premix provide corrosion control and microbiological control of the
system piping and components.
5.1.10 Riser System
The arrangement of the riser
system shall include a Viking
Model E-1 or F-1 Deluge
Valve
with
Conventional
Trim, Electric Release, a
primary Easy RiserTM check
valve with trim for preprimed
preaction
system,
an
TM
isolation Easy Riser check
valve including cold storage
by-pass trim.
22
The system must include a supervised system control valve upstream of
the deluge valve and a supervised system isolation valve downstream of
the isolation check valve. The downstream system isolation valve is
required to facilitate maintenance of the system and isolation of antifreeze
solution during maintenance and testing. A pressure relief valve on the
antifreeze side of the primary check valve shall be pre-set to protect the
sprinklers at 175 PSI (1 207 kPa) and piped to drain. This will handle
over-pressurization due to thermal differentials in the area of the
antifreeze piping and system operation. Consideration of location height
of PRV relative to the sprinklers must be taken into account. Calculate the
differential height and specific gravity of antifreeze at the operating
temperature of the freezer and size the PRV relief pressure accordingly.
The alarm line of the deluge valve shall be attached to an alarm pressure
switch (and mechanical water motor alarm, if required) that activates an
alarm due to activation of the system. An additional supervisory pressure
switch on the primary check valve system side is required in order to
provide a low pressure alarm in the case of antifreeze pressure loss due
to sprinkler operation without a fire condition. In this case the antifreeze
supply must be manually shut off to the low-pressure riser. There is an
isolation valve located on the antifreeze inlet line of the riser primary
check valve.
5.1.11 Alarm Test Connection
An alarm test connection is provided on the
deluge valve trim. When testing the alarm, the
downstream isolation valve and antifreeze
isolation valve must be shut before opening the
test valve.
This is a precaution in case the deluge valve
would inadvertently operate due to problems in
the trim components and cause water to enter the
system causing possible contamination of
antifreeze. After testing of the alarm, restore the
control valves to their normal operating position
and open the antifreeze supply valve.
5.1.12 Flow Test Valve (also known as Main Drain Valve)
Annual flow tests are required for
every sprinkler system. When
performing annual water flow tests
for the Pre-Primed Single Interlocked
Preaction Cold Storage System, you
will utilize the main drain of the
isolation check valve. This will allow
the primary check valve clapper to
open also. First, close the supervised
system isolation valve downstream of
the isolation check valve. Close the
23
antifreeze inlet ball valve. The deluge valve must be operated (opened) to
perform the flow test. Close the prime line valve and open the emergency
manual release valve. Make sure the diversion drain valve is open to flow
water to a drain area or the recovery tank as desired. Note: if antifreeze is
stored in the recovery tank, do not allow water to enter, or contamination
of solution will occur. Record the water supply pressure on the water
supply pressure gauge upstream of the deluge valve.
Open the main drain on the downstream Isolation check valve fully. This
will allow water to flow through the deluge valve and both the primary and
isolation check valves. Once the pressure gauge has settled to flowing
pressure, record the pressure on the water supply pressure gauge
upstream of the deluge valve.
After the water flow test is completed, close the water supply control valve
upstream of the deluge valve, drain all the water located between the
primary and isolation check valves. Then drain all water from between the
deluge valve and the primary check valve using the auxiliary drain on the
deluge valve trim. Close the main drain and auxiliary drain once water is
completely drained. Open the antifreeze supply isolation valve. The CS-1
pump will supply propylene glycol/water solution from the maintenance
solution supply tank. The CS-1 pump will stop running when the pressure
in the section of piping is 50 PSI (344 kPa) minimum or the set pressure
of the system pressure switch. Ensure there is no trapped air in the piping
between check valves by bleeding through the main drain valve of the
Isolation check valve. After system pressure is built, the CS-1 pump will
stop running. Open the down stream system isolation valve, when system
antifreeze pressure is at desired pressure and the CS-1 pump stops. Now
prime the deluge valve by opening the prime supply valve and watch for
pressure to build in the prime chamber of the deluge valve. Now, open
the system shut-off valve up stream of the deluge valve. Any supervisory
alarm switches silenced for system maintenance must be re-set. The
system is now in service.
5.2
Service Procedures
Drain-down of the individual system shall be done in the following manner.
If system operation has occurred:
1. After system trip or sprinkler(s) have operated and water has entered the
system, the complete system must be drained down immediately and
solution within the piping system disposed of.
2. All sprinklers are pendent type and must be removed and replaced with new
sprinklers. This is due to possible collection of water at each sprinkler and
creation of a small ice plug in each sprinkler.
3. If using the Viking Model AV-1 Air/vent Valve assembly the device also
breaks a vacuum in the piping system and provides faster and more
complete drainage of the system piping.
24
5.3
Taking the System Out of Service
If the system has to be taken out of service for maintenance on the system
piping, follow these instructions:
1. Close the water supply control valve to the riser being serviced.
2. Close the antifreeze supply valve to the riser being serviced.
3. If the system is being serviced, then the solution in the system can be
drained into clean containers or reclaim tank and reused as long as water
has not entered the systems. Solution should be checked at various points
while draining for proper refractometer readings to verify freeze-protection
properties.
4. Open vent/bleed valves at high points of the system or if the AV-1 Vent
Valve is applied it will automatically open.
5. Open the main drain and collect solution in clean containers or recovery tank
for re-use in system.
6. After the system is completely drained from the main drain, open any lowpoint drains to remove the remaining solution from the system.
5.4
Placing the System in Service
Placing the system in service after it has been completely drained:
1. Close the main drain valve on the riser.
2. Connect the propylene glycol/water solution fill pump (NOT the CS-1 pump)
to the connection located on the main drain assembly.
3. Close the main drain valve, vent/ bleed valves, and low-point drains if
opened. Ensure there are no openings on system piping.
4. Fill system with Firefighter Eliminator C or Eliminator F propylene glycol/
water solution. While filling, periodically open the manual vent/bleed valves
or allow the Model AV-1 Vent Valve to automatically open on system piping
to ensure air is eliminated from system piping. Slow fill is recommended to
minimize the entrainment of air.
5. Fill and pressurize system piping to 50 PSI (344 kpa) minimum using the
CS-1 Pump system to provide the final set system pressure.
6. Check for trapped air by cracking open vent/bleed valves or observe the AV1 Vent Valve. Ensure all trapped air is eliminated from the system.
7. After system pressure is attained, the water supply control valve up stream
of the deluge valve can be opened.

AUTOMATIC PRESSURE CONTROL SYSTEM
6.1
Description
The Viking ESFR Cold Storage System is fixed
fire protection for refrigerated or cold
warehouse storage. This system is also
appropriate for unheated storage applications
in areas subject to freezing. The piping system
is a closed system filled with pressurized
propylene glycol and water solution maintained
from a pressure pump system that controls and
25
maintains the desired solution pressure. The ESFR Pre-Primed Single
Interlocked Preaction Cold Storage System utilizes the Viking Deluge Valve and
Easy RiserTM Check Valve with special trim to isolate the antifreeze in the system
from the water supply. (NOTE: For previous Viking ESFR Cold Storage Systems,
which utilized a wet system with the Model J-1 Alarm Check Valve, please
contact the Viking Technical Services Department for details.)
In cold storage areas where temperature can fluctuate, over-pressurization of the
system can occur and cause the Pressure Relief Valve (PRV) to operate when
the set point is reached. Normal operation of PRVs include operation at 90-105%
of the set point and closing at 80% or above the set point. The Automatic
Pressure Control System (APCS) is designed to maintain a safe operating
pressure below the set point of the PRV and above the normal set pressure
range of the CS-1 antifreeze pump system. In a warm-up situation, temperature
fluctuations of the freezer area cause the pressure to also fluctuate. If the
pressure increases over the set point of the PRV, the APCS is desired to prevent
the PRV from operating, except for emergency situations where extended power
loss may occur.
The CS-1 Tank and Pump System is designed to maintain normal system
supervisory pressure at 50 PSI (344 kpa) minimum for pre-primed preaction
systems.
The APCS includes an electronic digital pressure switch that includes a normally
open SPST switch that is set to close at a pressure below the PRV set point and
open above the shut off pressure of the sprinkler system control switch of the
pump system. A normally closed solenoid valve is to be installed on the primary
Easy RiserTM Check Valve at the ¼” connection provided. A 115 volt AC, 50 or 60
Hz. 15 to 20 ampere GFI protected electrical power supply is to be provided
directly to the switch and solenoid valve. The power supply from switch to
solenoid valve shall be wired through a non-interrupted alarm pressure switch.
This will prevent the APCS valve from operating when system trips. As the
pressure switch closing set point is reached due to system pressure increase
upon warm-up of the freezer area, the switch will directly open the solenoid valve
and release antifreeze solution back to the system reservoir tank. When the
pressure reaches the lower setting, the switch will open, shutting off power to the
solenoid valve and stopping flow of antifreeze. The APCS will NOT operate
when the deluge valve has operated.
NOTE: The Viking ESFR Cold Storage System shall be designed by qualified fire
protection technicians, in conjunction with requirements of the Authorities Having
Jurisdiction. These systems are designed to meet the UL Listing requirements
described in Viking technical data for ESFR K25.2 Sprinkler VK510 for use with
propylene glycol/water solution, and the standards of NFPA 13 or other
organizations, and also with the provisions of governmental codes, ordinances,
and standards where applicable.
6.2
Application
For thermal cycling freezers and coolers having closed non-compressible
antifreeze systems, pressure can fluctuate drastically and possibly increase over
26
the PRV that protects the sprinklers at the ceiling at 175 PSI (1206kpa)
maximum. The APCS is required in order to eliminate operation of the PRV. For
warehouses with 40 ft (12,2 m) and 45 ft (13,7 m) ceiling heights, the head
pressure increase could require more precise pressure control. The APCS
allows for precise system control and prevents unwanted operation of the PRV.
Normal operation of PRV is 90-105% of the set point. The closing pressure is
only designed to 80% or greater of the set point. For pre-primed preaction
systems, the supervisory antifreeze pressure is maintained at 50 PSI (344 kpa)
minimum. The APCS is desired to protect the sprinklers and prevent the PRV
from operating unless an emergency power loss situation occurs. The APCS
maintains a safe system pressure in a precise range and prevents inadvertent
operation of alarms and PRV in thermal cycling type freezers and cooler
warehouses.
If the freezer system is backed up with a secondary power supply, it is
recommended that the APCS also be attached to this system for long power
outage situations. If not, the PRV will possibly operate to automatically protect
the system pressure in a warm-up situation.
6.3
System Control Switch
The APCS includes a digital pressure control switch. The switch is a
SPDT set up for Normally Open operation. Power supply required is
115 volt, 50 or 60 hz, with 15-20 amp GFI protected circuit. The
solenoid valve is wired directly through the system pressure switch and
system alarm pressure switch as described below. The Viking supplied
solenoid valve is a low wattage (2.0W) 1/4” valve. A strainer is also
furnished to protect the small orifice of the solenoid valve. As the
pressure increases over the high end set pressure the digital switch
closes and operates the solenoid valve open. As the low set pressure
is obtained the switch opens and allows the Normally Closed solenoid
valve to close. The pressure setting must be done in the field as described
below. It is recommended that the high end pressure be set at no more than 90%
of the nominal PRV setting less 5 PSI. The low end pressure for switch cut out
should be set at least 5 PSI less than the high end pressure setting.
As freezers are heated due to change is service or taken down for service, being
the system is a closed loop liquid filled system the pressure can increase
substantially. The APCS allows the pressure to be bleed off back to the
antifreeze containment tanks on a gradual time line as the freezer warms up.
This will prevent the PRV Valve from operating which normally has an operating
range of 90 to 105% of the set pressure and closes at 80% of the set pressure.
For extended power loss situation it is recommended to connect the APSC
system to the back-up power supply. Otherwise the PRV valve will still protect
the system in a power loss situation.

Description
The Viking CS-1 Tank and Pump Package is an integrated storage tank and
pumping system designed for use with the Viking ESFR Cold Storage System.
This is a Pre-Primed Single Interlocked Preaction System providing fixed fire
protection for refrigerated or cold warehouse storage and is also appropriate for
unheated storage applications in areas subject to freezing, to a minimum
temperature of -21 °F (-29.4 °C).
This is a pre-primed preaction system with electric release that utilizes a deluge
valve with conventional and electric release trims. The riser consists of two
Viking Easy RiserTM Swing Check Valves, one with special cold trim and the
second with by-pass trim to isolate the antifreeze in the system from the water
29
supply. The tank and pump system automatically maintains the supervisory
solution pressure in the piping above the check valves, until the detection system
is activated. When the detection system is activated, the deluge valve is operated
from the system releasing control panel. In the event of a fire condition, the
detection system operates the deluge valve and pressurizes the system with the
design discharge water pressure. The system pressure control switch is wired
through the alarm pressure switch located on the deluge valve. In a fire condition,
the CS-1 antifreeze pump unit keeps the supply solenoid valve closed that is
supplying the operated riser system. In a situation where a sprinkler opens,
breaks off, or pipe ruptures, causing a low pressure supervisory condition without
a fire condition, the low pressure supervisory switch located on the primary check
valve will provide an alarm. In this case, the antifreeze supply valve on the
alarmed riser must be manually shut off. The pump uses antifreeze in the storage
tank to maintain system pressure and make up for minor system leaks.
The system is designed to accept up to 50% propylene glycol and water premix
solution. It is recommended that Viking certified premix be used. Do not mix
different antifreeze solutions within the system.
WARNING: Motors, electrical equipment, and controls can cause electrical arcs
that will ignite a flammable gas or vapor. Never operate or repair in or near a
flammable gas or vapor. Never store flammable liquids or gases near the unit.
SAFETY: This equipment is designed to be safe in the use for which it was
planned, provided it is installed, started up, operated, and maintained in
accordance with the instructions in this manual. Therefore, all personnel who
install, use, or maintain the equipment must understand this manual. The unit
contains electrical components that operate at line voltage and moving parts.
Before working on the unit, isolate and lock it out from the electrical supply. All
maintenance operations must be performed by qualified persons who have
knowledge in the necessary precautions.
NOTE: The Viking ESFR Cold Storage System shall be designed by qualified fire
protection technicians, in conjunction with requirements of the Authorities Having
Jurisdiction. These systems are designed to meet the UL Listing requirements
described in Viking technical data for ESFR K25.2 Sprinkler VK510 for use with
propylene glycol/water solution, and the standards of NFPA 13 or other
organizations, and also with the provisions of governmental codes, ordinances,
and standards where applicable.
7.2
Operating Principle
The tank and pump system maintains antifreeze in sprinkler system piping at
desired supervisory pressure 50 PSI (344 kpa) minimum recommended
pressure. A pressure switch on the unit senses the CS-1’s discharge manifold
pressure and turns the pump on as the unit pressure drops to a preset pressure,
and then stops the pump as unit pressure rises to a higher preset pressure. A
level switch mounted in the storage tank opens when the liquid level is low.
When the level switch opens, pump operation is inhibited and a set of dry
contacts changes state for the user’s supervisory system. Terminals 21, 22, and
23 are for connection of low alarm devices. Also, the primary check valve
30
includes a low-pressure alarm switch that indicates a loss of supervisory
pressure and requires a manual shutoff of the antifreeze supply valve.
Up to six individual risers are connected to the CS-1 Tank and Pump System
through normally closed solenoid valves. The supervisory pressure switch and
flow alarm switch for each system are connected on site to the CS-1 system
control. As system supervisory pressure drops, the corresponding solenoid valve
opens, allowing flow from the CS-1 system to that system. When system
pressure reaches the system set point, the system pressure switch opens and
the CS-1 control closes that solenoid valve. In the case of flow due to a system
operation, the normally closed contacts of that system’s flow alarm pressure
switch open, and the CS-1 control prevents that system’s solenoid valve from
opening, regardless of system pressure.
A suitable portable pump can be utilized to fill the system to the static water
pressure. (The CS-1 pump can be used for filling the system initially at 15 GPM
(56 l/min) to 100 ft. head pressure or system static pressure, however, it is a less
efficient pump for filling the system because of the duration of time required to do
so. To fill the system, the CS-1 is connected to the antifreeze supply. The system
to be filled is selected using two toggle switches on the CS-1 control enclosure.
Antifreeze from the supply is pumped to the system piping. Pump operation is
manually controlled during the fill process. The CS-1 pump is to be utilized to
bring the solution to maintenance pressure, [normally 50 PSI (344 kPa) pressure]
at the primary check valve and is designed to maintain system pressure once the
system is initially filled.
Two modes of electrical control are available. Manual operation allows the user
to operate the pump motor by means of a switch regardless of the electrical
controls status. Automatic operation uses the unit’s pressure switch to operate
the pump based unit pressure. Flow to each riser is controlled by that system’s
pressure switch and flow alarm switch. In “Automatic” mode, pump operation is
limited to six times per hour. Also, pump operation is inhibited at low liquid level
in the tank.
WARNING: The CS-1 system must be attended at all times in Manual mode. The
pump can operate without liquid in Manual mode, which will damage the pump.
Running the CS-1 without fluid in Manual mode voids the warranty. This pump is
not self- priming.
The storage tank is opaque to allow visual indication of the antifreeze leveling. A
Y-Strainer is included on the pump suction line. A locking valve is included on
discharge line. Lock in the open position. This valve is used to isolate the
antifreeze storage tank for maintenance. A check valve in pump discharge piping
prevents antifreeze backflow from the system, which would damage the pump.
An adjustable pressure relief valve is included to protect the pump discharge
piping. This relief valve must be set at 10 PSI (68,9 kPa) above the pump system
pressure switch. All components of the pump unit are compatible with the
antifreeze solution and rated to a maximum pressure of 225 PSI (1 551 kPa).

CS-1 Control Scheme
7.3.1
General
The CS-1 Tank and Pump System maintains pressure for up to six risers
with individual control to each riser. A two-way normally closed solenoid
valve is connected to each riser. The pressure maintenance switch on
each riser controls the corresponding solenoid valve. At a low riser
pressure condition, the solenoid opens, allowing flow from the CS-1 to
that riser. In the case of operation of a riser due to flow from a sprinkler,
the riser’s alarm pressure switch sends a signal to the CS-1 control panel,
and keeps the corresponding solenoid valve from opening.
A drop in pressure operates the CS-1 pump. Pump operation is controlled
by the pressure switch and level switch mounted on the CS-1. There are
two normal operating modes for the CS-1 Tank and Pump Package,
“Manual” and “Automatic”. The Manual mode is used for filling the unit’s
tank and filling systems through the CS-1, using the unit’s pump. The
Automatic mode maintains system(s) pressure(s) after filling is complete.
7.3.2
Operation
The pressure switch mounted on the CS-1 controls pump operation.
When the pressure at the CS-1 drops, the pump will turn on until the
pressure at the CS-1 rises above a set level. In “Automatic” mode, pump
operation is inhibited if the level of liquid in the unit’s storage tank drops
below the level switch height.
In “Manual” mode, the pump operates when CS-1 pressure drops, and
tank level is satisfied, and a system valve is selected, and that system
pressure is not met, and there is no alarm condition. The pump can also
fill the tank in Manual mode. For tank filling, the level switch position is not
used and the operator must start and stop the pump, using the “Hand”
position of the Hand-Off-Auto Switch on the control panel. (Note: In
order to operate in manual mode, all pressure switches must be properly
connected.)
In Automatic mode, there is a 10-minute time delay between pump
operations. After the 10-minute delay, the pump operates if the CS-1
pressure drops and tank fluid level is above the level switch height. When
the pump shuts off, the 10-minute timer starts again and the pump will not
operate until 10 minutes is complete.
7.3.3
System Solenoid Valve Operation
Each system (riser) pressure switch and alarm pressure switch contacts
are connected in series to one input on the PLC. The system pressure
switch closes on falling pressure. The alarm pressure switch normally
closed contacts are used and open in the alarm condition.
32
In Automatic mode, each system solenoid valve opens if its system
pressure drops to a low-pressure condition and there is no alarm
pressure signal. In Manual mode, each system valve is selected by
means of two selector switches and the solenoid valve opens as long as
system pressure is below the set-point value and there is no system
alarm.
7.3.4
Level Switch Relay Coil Operation
The level switch relay coil is energized when tank level is above the level
switch height. This is when tank level is satisfied. The switch relay coil deenergizes when tank level drops to the level switch height, at low tank
level.

Installation
7.4.1
Receiving And Inspection
When the equipment is received, immediately inspect it for shortages and
visible and concealed damage. If the equipment has been damaged in
shipment or shortages are noticed, immediately notify the carrier and file
a claim.
7.4.2
Handling
Move the CS-1 on the shipping pallet as close to the final location as
possible. Always lift the unit from underneath. Never lift the unit when it is
full of liquid. Personal injury and/or equipment damage could result.
Ensure that all equipment used to lift the CS-1 is capable of lifting the
weight. Nylon straps and soft rigging devices should be used whenever
possible to protect the components and finish.
If the unit is being transported overhead, be sure that all personnel are
alerted and safety procedures are followed.
7.4.3
Location
WARNING! DO NOT INSTALL THE CS-1 IN AN ENVIRONMENT OF
CORROSIVE CHEMICALS, EXPLOSIVE GASES, POISONOUS
GASES, STEAM HEAT, AREAS OF HIGH AMBIENT CONDITIONS, OR
EXTREME DUST AND DIRT.
Install the CS-1 indoors in a clean, dry, non-corrosive environment. This
equipment is not to be installed outdoors exposed to the weather.
Position the CS-1 in an upright position on a solid, level, vibration-free
surface capable of supporting the weight of the unit and liquid in the tank.
Bolt the unit to the floor using the bolt holes provided in the frame. Always
shim the unit level before bolting it to the floor. Install the CS-1 in a
protected, well-ventilated area where the ambient temperatures are
between 40 °F and 100 °F (4 and °C).
Locate the CS-1 to allow access to supply and discharge connections.
Clearance around the unit should be at least 24“ on all sides for
maintenance. Some jurisdictions require specific clearances around
equipment. Check with all local Authorities to ensure compliance with
applicable state, local, and national codes.
7.4.4
Piping And Connections
A slight downward slope from the supply container to the CS-1 supply
valve connection is recommended to maintain positive head on the pump
inlet.
Always use a backup wrench when making piping connections to avoid
damage to the unit’s piping.
36
Size piping between the CS-1 and the system to minimize pressure drop.
Too small of a line size restricts pump flow, lowering capacity when filling
the system. Lower capacity while filling the system requires longer fill
times. The sprinkler system must contain air vent/bleed valves at all local
high points. These are used to let air out of the system while filling with
antifreeze. Consult the system instructions for specifics.
Individual check valves and isolation valves are required for each system.
This allows system maintenance without disturbing other systems the CS1 is connected to. Piping and/or hoses from the antifreeze supply
containers to the unit should be sloped downhill slightly to provide positive
head on the pump suction connection. These lines should be as large as
possible and as short as possible to provide unrestricted flow to the pump
while filling. A separate shut-off valve in the supply line is required.
Unit piping is copper, brass and bronze. An aluminum manifold is
included for mounting multiple system solenoids. Use dielectric unions to
isolate copper piping from iron piping, if used, to reduce the possibility of
electrolytic action on pipes and other components.
All pipes should be de-burred and threaded to a proper depth and length
before installation. Threads should be inspected for cleanliness and depth
of cut. Good quality pipe compound should be used to ensure a good,
leak tight fit of piping components.
NOTE: Pipe must be supported separately from the CS-1. At no time
should the CS-1 support the weight or load of the pipe. Acceptable pipe
mounting devices would be unistrut supports anchored to walls, hangers
suspended from ceilings, or pedestals mounted from the floor. Be sure all
pipe installation conforms to all building & fire codes.
7.5

ALARM SWITCH
9.1
INSTALLATION
WARNING: The Alarm Pressure Switches are general service
switches, not designed for use in explosive atmospheres. Refer
to the technical data page for the Explosion-Proof/Watertight Alarm Pressure
Switch intended for use in those environments.
1. Refer to the current Viking Trim Chart for the valve used to determine the
appropriate location for installing the Viking Alarm Pressure Switch on Viking
Trim. Viking Trim Sets provide:
a. An alarm connection, equipped with an alarm test valve, and an alarm shutoff valve for switches used for local alarms and,
b. A non-interruptible alarm connection, equipped with an alarm test valve, for
switches used to signal electric alarm panels and remote alarms.
CAUTION: Closing any shut-off valve in the alarm piping leading to the Alarm
Pressure Switch will render the switch inoperative.
2. When installing the general service Alarm Pressure Switch, apply Teflon® tape
sealant to the male threads only. Install the Pressure Switch in a ½" (15 mm)
pipe fitting. Use a wrench applied to the wrench flats to tighten the unit. Do not
over-tighten.
a. Mount the Alarm Pressure Switch in the upright position (threaded
connection down).
3. To wire the unit proceed as follows:
a. De-energize electrical circuits involved.
b. Use the special wrench, supplied with the switch, to loosen and remove the
tamper-resistant screws. Remove cover. Use care not to lose the rubber Oring screw retainers.
c. Connect conduit to the conduit opening provided. See “Technical Data” for
size of opening.
d. Connect electrical circuitry for the alarm and any auxiliary equipment being
controlled by the switch (Refer to Figures B, C, and D).
Note: Wire all devices to national and local codes and requirements of the
Authority Having Jurisdiction.
4. Replace cover and tighten the tamper-resistant screws.
5. Energize the circuits.
6. Test for proper operation of the device.
7. The switch shall be wired as a normally closed circuit.
10.0
PRESSURE RELIEF VALVE
The pressure relief valve relieves excess system pressure caused by surges
or temperature changes. The pressure rating of the relief valve indicates an
operating range of pressure for both opening and closing of the valve.
Standard relief valves are required to OPEN in a range of pressure between
90% and 105% of their rating. The valves are required to CLOSE at a
pressure above 80% of that rating.
41
The relief valve should be installed where it is easily accessible for maintenance. Care
should be taken that the relief valve CANNOT be isolated from the system when the
system is operational. A relief valve should never have a shutoff valve or a plug
downstream of its outlet. The PRV MUST be piped to an adequate drain. Operation will
discharge antifreeze or water from its outlet.
See Section 19.0 System Parts List for listing of part numbers and pressures available.

ANVIL COUPLINGS, SEALS & LUBE
11.1
Couplings
The C-4 rigid coupling is design for rigid piping applications. The C-4 is specially
designed to provide a rigid, locked-in pipe connection to meet the specific
demands of rigid design steel pipe.
Housing: Ductile iron conforming to ASTM A-536, Grade 65-45-12
ANSI Bolts and Heavy Hex Nuts: Heat treated, oval neck track head bolts
confirming to ASTM A-183 Grade 2with a minimum tensile strength of 110,000
psi and heavy hex nuts of carbon steel conforming to ASTMA-563 Grade A or

Gaskets: Grade “E” EPDM. NSF-61 Certified. -30 °F to 230 °F (Service
Temperature Range) (40 °C to 110°C) Recommended for water service, diluted
acids, alkalys solutions, oil-free air and many chemical services. Xtreme™
Lubricant is required for freezer applications.
11.2
Flush Gap Gaskets
Flush gap gaskets are designed to prohibit contamination from building up in the
gasket cavity. The centering rib fits flush over the gap between the two pipe ends
thus closing off the gasket cavity. Not recommended for temperatures above 160
°F.
11.3
Lubricant
GRUVLOK Xtreme Lubricant has been developed for use with Gruvlok couplings
in services where improved lubrication is beneficial. This lubricant has an
operating temperature range from -65 °F to 400°F, well exceeding the
temperature range of Gruvlok gaskets. This lubricant is waterproof, thereby
eliminating water wash-out and it will not dry out in the absence of water. There
are five primary applications where the Xtreme Lubricant will provide increased
benefits: low temperature applications (below -20 °F), high temperature
applications (above 180 °F), applications where increased pipe joint flexibility is
needed, lubrication of gaskets in copper systems, and for the lubrication of
gaskets on HDPE couplings. Since it is formulated from a non-hydro carbon
42
base, it can be used with EPDM, Nitrile and Fluoroelastomer gasket materials. It
is not to be used with silicone gaskets.
• In low temperature applications the gasket will shrink, thereby lowering the
sealing force on the gasket sealing lips. The temperature change will also force
the gasket to slightly re-position itself. This will cause pipe end sealing
surfaces, with small cuts or damage, to become more susceptible to leakage.
Gruvlok Xtreme Lubricant will maintain it’s lubricating properties at lower
temperatures allowing a properly lubricated pipe end and gasket (assembly) to
re-position itself during temperature cycles.
• For high-temperature service and copper systems, it is required that the gasket
be lubricated not only on the outside, as with the normal installation of a
Gruvlok gasket, but also on the inside. Lubrication on the inside of the gasket is
easily accomplished by turning the gasket inside out and applying the lubricant.
Gruvlok Xtreme Lubricant will maintain it’s lubricating properties at higher
temperatures, allowing a properly lubricated pipe end and gasket assembly to
re-position itself during temperature cycles. Lubrication of the pipe end and
gasket will help the gasket to adjust into the proper sealing position during
temperature cycles. The lubricant on the interior of the gasket will act to
improve the chemical resistance of the gasket material by providing a thin
lubricant barrier between the piping system fluid and the gasket surface. This is
particularly important at higher temperatures where oxidizing agents in the
piping system become more aggressive. However, gasket chemical
compatibility must still be considered.
• The Gruvlok Xtreme Lubricant has been formulated from low viscosity, nonpetroleum based oils to ease spreading of the lubricant. In applications where
pipe movement is expected, proper lubrication of the gasket’s exterior assists
the gasket into the proper sealing position as pipe system movement occurs.
This lubricating film enhances our flexible coupling gasket’s ability to
compensate for axial, transverse and rotational pipe movements.
• Gruvlok Xtreme Lubricant is the only Gruvlok lubricant that is to be used with
Gruvlok couplings and gaskets in HDPE and copper piping systems. It’s low
temperature capability and lubricity ensure a highly reliable connection.
Gruvlok Xtreme Lubricant is a Teflon fortified white, tasteless and odorless
grease made from Silicone Oil and other ingredients that are safe to ingest. It is
sanctioned by the FDA under C.F.R. 21.172.878 & 21.177.1550 (Incidental
Food Contact).
Caution: Silicone based lubricants are not allowed in some facilities.

HEAT TRACE SYSTEM & INSULATION
14.1 Insulation of Riser Main
The riser and supply main coming from the freezer area that is maintained at the desired
freezing temperature to the valve riser system, which is in a heated area will produce
frosting on the exterior of the piping. Hydronic Convective heat transfer takes place in
this type system in which cold antifreeze is circulated from the freezer toward the
warmer piping area. This circulation allows the riser pipe to maintain a very cold
temperature as supplied from the freezer area. The moisture in the heated area air will
cause formation of liquid on the pipe surface. Due to the freezing temperature of the
antifreeze Frost will form on the exterior of the supply piping. In order to prevent the
moisture from building on the pipe exterior surface, fiberglass Thermal insulation with a
polyester vapor barrier wrap is required to be applied to the supply piping from the
freezer wall to the bottom of the Isolation check valve. In severe cases the insulation
may require heat tracing under the insulation in order to maintain a higher temperature
at the pipe exterior surface under the insulation.
14.2 Insulation of Isolation Check Valve
Viking has available a preformed insulation cover that allows for trim piping connections
and removal for valve maintenance. These are custom manufactured for each check
valve size.
14.3 Heat Trace System
Viking has available through our SupplyNet locations a self regulating heat trace system
when required. The temperature control unit provides automatic control of the set pipe
surface temperature. The length of heat trace wire and pitch of wrap on the pipe is
determined by the given temperature conditions. Sizing of wire length and wattage is
available on request.

SYSTEM FILL PROCEDURE
15.1
Filling The Reservoir Tank
The CS-1 has been designed to fill the reservoir tank using either of two
methods: gravity fill or pumped fill. NOTE: This is not a self-priming pump.
Manual prime or fill the reservoir for prime.
NOTE: Never leave the unit unattended when filling the system or tank. Running
the pump dry, without liquid, will damage pump seals and possibly damage pump
impeller. Follow the steps below:
15.1.1 Gravity Fill:
1. Turn off and isolate the electrical supply to the unit.
2. Close supply isolation valve.
3. Connect the antifreeze supply container to the supply isolation valve.
A flexible hose may be used, but must not restrict the flow from the
supply container to the valve. An additional isolation valve must be
installed in the line between the supply container and unit’s supply
isolation valve. A slight downward slope from the supply container to
the valve connection is required to prime the pump and maintain
positive head on the pump inlet. Always use a backup wrench when
making piping connections to avoid damage to the unit’s piping.
4. Open the shut off valve on the supply container and supply isolation
valve on the CS-1.
5. Open the pump suction isolation valve and allow liquid to enter the
reservoir tank. If there is enough liquid in the supply container, the
tank may be filled completely using this method. The tank is full when
the liquid level rises to the top of the straight section of the tank.

If there is not sufficient liquid in the supply container to fill the tank or
the tank fills too slowly, the pump on the CS-1 may be manually
operated to speed up this process. Follow steps 1 to 4 above and 7 to
11 below to fill the storage tank using the pump.
Close the pump suction isolation valve and open the tank fill isolation
valve.
With the CS-1’s switch in the “OFF” position, turn on power supply to
the unit.
Position switches “A” and “B” in the center/off position. Switch the
“OFF-ON” switch to “ON” and the “Man-O-AUTO” switch on the unit
control panel to “Man”. Liquid will begin to fill the storage tank at the
fill connection.
Be careful to observe the liquid level to prevent over filling. When the
liquid level reaches the top of the straight section of tank, switch the
unit’s “Man-O-AUTO” switch to off.
Close the supply isolation and tank fill isolation valves. Open the
pump suction valve.
47
15.2
Filling Systems
A suitable portable pump can be utilized to fill the system. (The CS-1 pump can
be used for filling the system initially at 15 GPM (56 l/min) to 100 ft. head
pressure or supervisory pressure, however, it is a less efficient pump for filling
the system because of the duration of time required to do so. To fill the system,
the CS-1 is connected to the antifreeze supply. The system to be filled is
selected using two toggle switches on the CS-1 control enclosure. Antifreeze
from the supply is pumped to the system piping. Pump operation is manually
controlled during the fill process. The CS-1 pump is to be utilized to bring the
solution to supervisory pressure, [recommended 50 PSI (344 kPa) pressure] and
is designed to maintain supervisory pressure once the system is initially filled.
Appropriate vent/bleed valves must be installed on each system’s piping at all
local high points to allow air to escape while liquid fills the system.
NOTE: Never leave the unit unattended when filling the system. Running the
pump dry, without liquid, will damage pump seals and possibly damage the pump
impeller.
Follow the steps below:
1. Turn off and isolate the electrical supply to the unit.
2. Close the Supply Isolation and Tank Fill valves.
3. If not already connected to fill the storage tank, connect the antifreeze
supply container to the supply isolation valve. A flexible hose may be used,
but must not restrict the flow from the supply container to the valve. An
additional isolation valve must be installed in the line between the supply
container and unit’s supply isolation valve.
A slight downward slope from the supply container to the unit’s valve
connection is required to prime the pump and maintain positive head on
pump inlet. Always use a backup wrench when making piping connections to
avoid damage to the unit’s piping.
4. Open the shut off valve on the supply container and supply isolation valve
on the CS-1.
5. Open high point vent/bleed valves on the system.
6. Select system to be filled using switches “A” and “B” (refer to Figure 1 on
page 51 d). Use the table below to determine switch “A” and “B” position.

With the CS-1’s switch in the “OFF” position turn on the power supply to the
unit. Turn the “Off-On” switch to “ON”.
Switch the “Man-O-AUTO” switch on the unit control panel to “Man”. Liquid
will begin to fill the selected system.
As the system fills, monitor the system vent/bleed valves. Close each valve
when liquid leaks from it.
When the liquid leaks from the uppermost vent/bleed valve, close the vent
valve. The system pressure switch will close that system’s solenoid valve.
The pump pressure switch will turn the pump off.
If another system is to be filled, turn the “Man-O-AUTO” switch to OFF and
select the next system using switches A and B.
Turn the “Man-O-AUTO” switch to “Man” and repeat steps 8 through 10.
After filling all systems and the CS-1 tank, close the supply isolation valve.
All air must be out of the system before switching the unit to maintenance
mode. Follow the system manufacturer’s recommendations to ensure all air
is removed.
16.0 SYSTEM AND SOLUTION TEST AND MAINTENANCE
Field mixing of propylene glycol and site water is strictly prohibited, as the control of the
mixture cannot be assured. Improper field mixing of solution can result in reduced
capability to prevent freezing or to control a fire. Firefighter Eliminator F is already
premixed and ready to use.
Filling the System
In the main drain line between the valve and primary check valve inlet, a tee is provided
with a 1” NPT connection for supply and maintenance of the antifreeze solution to the
system above the check valve. A suitable portable pump can be utilized to fill the system
to the static water pressure. (The CS-1 pump can be used for filling the system initially at
15 GPM (56 l/min) to 100 ft. head pressure or system static pressure. However, it is a
less efficient pump for filling the system because of the duration of time required to do
so. The CS-1 pump is to be utilized to bring the solution to maintenance pressure
[recommended 50 PSI (344 kPa)] and is designed to maintain supervisory pressure
once the system is initially filled. When filling the system with antifreeze solution, all air
must be bled from the system (as described in data page 45 a-j) in order to make final
and maintained antifreeze solution pressure non-compressible.
16.1
Testing the Solution
Antifreeze solution shall be checked quarterly (for gridded systems), or semiannually (for tree type configurations) with a refractometer to detect the
concentration of antifreeze solution and effectiveness against freezing. Sampling
shall be taken from multiple points within the freezer system (refer to the
instructions on data pages 45 e and 45 i for fluid sampling). When draining
sample antifreeze solution from the system, be sure to shut off the system control
valve directly upstream of the deluge valve so that water doesn’t enter the
system. After the CS-1 pump has restored the antifreeze solution pressure,
ensure that the water supply control valve is returned to the fully open position
once fluid sampling is completed. Multiple propylene glycol/water solution test
49
valves are to be installed in several areas on the system piping for testing with a
refractometer (refer to data page 45 a-j for testing requirements and procedures).
If the propylene glycol/water solution becomes diluted or does not pass the
refractometer test, the entire system is to be drained. All sections of trapped
piping are to be drained. Five percent (5%) of the pendent ESFR sprinklers in all
locations throughout the system are to be removed and inspected for frozen
solution. If any of the pendent ESFR sprinklers are found with frozen solution, all
the pendent ESFR sprinklers are to be removed and replaced with new Viking
K25.2 Pendent ESFR VK510 Sprinklers prior to re-charging system with new
35% or 50% premix propylene glycol/water solution. If the 5% of removed
sprinklers are not damaged, they can be re-installed in the system.
