SAFETY CONSIDERATIONS
Installing, starting up, and servicing air-conditioning equipment can be hazardous due to system pressures, electrical
components, and equipment location (roofs, elevated structures, etc.).
Only trained, qualified installers and service mechanics
should install, start up, and service this equipment (Fig. 1).
Untrained personnel can perform basic maintenance functions such as cleaning coils. All other operations should be
performed by trained service personnel.
When working on the equipment, observe precautions in the
literature and on tags, stickers, and labels attached to the
equipment.
• Follow all safety codes.
• Wear safety glasses and work gloves.
• Keep quenching cloth and fire extinguisher nearby when
brazing.
• Use care in handling, rigging, and setting bulky
equipment.

WARNING
Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation. There
may be more than one disconnect switch. Tag all disconnect locations to alert others not to restore power until work
is completed.
WARNING
DO NOT USE TORCH to remove any component. System
contains oil and refrigerant under pressure.
To remove a component, wear protective gloves and goggles and proceed as follows:
a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure from system using both high-pressure and low pressure ports.
c. Traces of vapor should be displaced with nitrogen
and the work area should be well ventilated. Refrigerant in contact with an open flame produces toxic
gases.
d. Cut component connection tubing with tubing cutter
and remove component from unit. Use a pan to catch
any oil that may come out of the lines and as a gage
for how much oil to add to the system.
e. Carefully unsweat remaining tubing stubs when necessary. Oil can ignite when exposed to torch flame.
Failure to follow these procedures may result in personal
injury or death.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

For 30RAP070-150 (see Fig. 3): When chillers are arranged
in parallel, a minimum of 10 ft (3048 mm) between chillers is
recommended. Acceptable clearance on the cooler connection
side or end opposite the control box of the unit can be reduced
to 3 ft (1 m) without sacrificing performance as long as the remaining three sides are unrestricted. Acceptable clearance on
the side with a control box can be reduced to 4 ft (1.3 m) due to
NEC (National Electric Code) regulations, without sacrificing
performance as long as the remaining three sides are unrestricted. Clearances between chillers in dual chiller applications may
be reduced to 6 ft (1.8 m) without sacrificing performance provided the remaining sides are unrestricted. For acceptable
clearance with layout involving more than 2 chillers, please
contact application engineering.
CAUTION
DO NOT re-use compressor oil or any oil that has been
exposed to the atmosphere. Dispose of oil per local codes
and regulations. DO NOT leave refrigerant system open to
air any longer than the actual time required to service the
equipment. Seal circuits being serviced and charge with
dry nitrogen to prevent oil contamination when timely
repairs cannot be completed. Failure to follow these procedures may result in damage to equipment.
INSTALLATION
Storage — If the unit is to be stored for a period of time
before installation or start-up, be sure to protect the machine
from construction dirt. Keep protective shipping covers in
place until the machine is ready for installation.

MINIMUM
Step 1 — Place and Rig the Unit
PLACING UNIT — For 30RAP010-060 (see Fig. 2): When
parallel chillers are aligned such that coils face each other, a
minimum of 6 ft (1829 mm) is recommended. When the parallel arrangement has only one coil drawing air from the space
between chillers, a minimum of 3.5 ft (1067 mm) is recommended. When parallel chillers have no coils facing each other
(a back-to-back arrangement), be sure to maintain the larger of
the recommended service clearances associated with each
chiller (see the certified drawings). Due to NEC (National
Electric Code, U.S.A.) regulations, a minimum clearance of 4
ft (1219 mm) must be maintained on the side of the chiller that
has an electrical box. Chiller fan discharge must be at least as
high as adjacent solid walls. Installation in pits is not
recommended.

These instructions cover installation of 30RAP010-150 aircooled liquid chillers. Refer to Fig. 4 for model number to determine factory-installed options.
RIGGING — Preferred method for rigging is with spreader
bars from above the unit. Use shackles in lifting holes. Rig at a
single point with 4 cables for size 010-115 units, 6 cables for
size 130 and 150 units, or use spread bars. All panels must be
in place when rigging. See rigging label on unit for details concerning shipping weights, distance between lifting holes, center
of gravity, and lifting ring dimensions. See Tables 1A and 1B
for physical data. Refer to Fig. 5 for unit weights. See
Fig. 6A and 6B for rigging label.
If overhead rigging is not possible, place chiller on skid or
pad for rolling or dragging. When rolling, use a minimum of
3 rollers. When dragging, pull the pad. Do not apply force to
the unit. When in final position, raise from above to lift unit
off pad.

MINIMUM*
* Minimum for when coils face each other. Less clearance is
required in other configurations.
†Clearance of 3.5 ft is required when a coil faces the wall. When
there is no coil facing the wall, see the certified drawing for the
required service clearance.
CAUTION
All panels must be in place when rigging. Damage to unit
could result.

*All units have Victaulic connections, sized for IPS Carbon Steel piping.
†Flow switch and strainer are standard on all units, with or without hydronic package.
Step 3 — Cooler Fluid and Drain Piping Connections
be of a material that will not cause any galvanic corrosion. For
this reason, galvanized steel pipe or other dissimiliar metals
must not be used unless joined by a dielectric coupling.
Provide a means of venting air from the high point of the
field-installed piping as required. Install field-supplied drains
in both the entering and leaving fluid connections.
After field piping is complete, freeze-up protection is recommended using inhibited ethylene glycol or other suitable inhibited antifreeze solution and electric heat tapes in areas
where piping is exposed to low ambient temperatures (34 F
[1В° C] or below). Heat tapes should possess a rating for area
ambient temperatures and be covered with a suitable thickness
of closed-cell insulation. Route power for heating tapes from a
separately fused disconnect. Identify disconnect as heat tape
power source with a warning that power must not be turned off
except when unit is being serviced.
Installation of water systems should follow sound engineering practice as well as applicable local and industry standards.
Improperly designed or installed systems may cause unsatisfactory operation and/or system failure. Consult a water treatment specialist or appropriate literature for information regarding filtration, water treatment, and control devices.
ALL UNITS — These chillers are supplied with factoryinstalled strainer (including blow-down valve) in the entering
fluid piping and flow switch in the leaving fluid piping. Flow
switch wiring is factory installed.
CAUTION
Do not circulate water through unit without strainer in
place. Failure to use the strainer represents abuse and may
impair or otherwise negatively affect the Carrier product
warranty.
Piping connections are located on the front of the chiller
when facing the control panel for sizes 010-030 and at the end
opposite the control panel for sizes 035-060. For sizes 070-150,
piping connections are on the right side when facing the control
panel and (Circuit B) of the chiller. See Fig. 7-12, depending on
model. See Fig. 13-15 for accessory storage dimensions.
All sizes have Victaulic IPS connections as shown in the
physical data tables. The water connections are copper swaged
to Victaulic IPS. Any connecting pipe to the 30RAP unit must

the piping between the unit and the valves, following all
applicable state and local codes.
System Pressurization — A proper initial cold fill pressure
must be established before the filling of the unit. The initial
cold fill pressure is the pressure applied at the filling point to
fill a system to its highest point, plus a minimum pressure at the
top of the system (4 psi [28 kPa] minimum) to operate air vents
and positively pressurize the system.
The compression tank (sometimes called expansion tank) is
very important to system pressurization. The compression tank
actually serves several purposes:
1. Provide net positive suction head required (NPSHR) for
the pump to operate satisfactorily.
2. Set system pressure.
3. Accommodate expansion/contraction of water due to
temperature changes.
4. Acts as a pressure reference for the pump.
The compression tank pressure must be set BEFORE the
system is filled. Expansion tanks are factory supplied on sizes
010-060 only and field supplied on all other sizes. The tanks
are pre-charged at the factory to 40 psig (276 kPa). If the
30RAP unit with expansion tank is the high point in the system, tank pre-charge pressure of 40 psig (276 kPa) will be adequate. If the 30RAP unit with expansion tank is NOT at the
high point in the system, then the minimum pre-charge pressure for the water system must be determined using Table 2
and the method below:
Tank Pressure = 4 + (height from tank to top of
system in feet/“X”)
[27.6 + (height in m x 22.6/“X”)]
UNITS WITH FACTORY-INSTALLED HYDRONIC
PACKAGES — The 30RAP chillers with factory-installed
hydronic packages are designed for use with closed systems,
meaning that there is no more than one water-air interface in
the water loop. Cooling tower loops, for example, have two
water-air interfaces (sump and nozzles) and would thus be classified as open, whereas a correctly designed chilled water loop
with the only water-air interface being in the expansion tank is
closed. Since closed and open water systems behave very differently, these instructions assume that the chilled water loop is
closed. A system installed incorrectly such that air is not handled properly — pipe leaks, vent leaks, air in pipes, etc. — may
behave as an open system and thus have unsatisfactory operation. Pump seal wear can also cause leaks that cause poor system operation.
Proper closed system design and installation procedures
should be followed closely. The system must be constructed
with pressure tight components and thoroughly tested for
installation leaks. Factory-supplied hydronic systems are available with single or dual (for back-up) pumps.
Figure 16 shows a typical installation with components that
might be installed with the hydronic package of the 30RAP
unit. The factory-installed system includes all of the components within the dashed lines. Figure 17 illustrates a typical
dual pump package for the 010-030 size models.
NOTE: For units with single pumps, it is recommended that
isolation (shutoff) valves be placed exterior to the unit to
allow removal and service of the entire pump assembly, if
necessary. Units with dual pumps have pump isolation
valves provided. Also, if the unit is isolated with valves, a
properly sized pressure relief valve should be installed in

tanks) in a system (unless manifolded together). If system
volume or other design considerations warrant the placement
of another expansion tank somewhere in the system, the expansion tank in the 30RAP hydronic package MUST be disconnected from its hose and the end of the hose securely plugged.
This is also true for applications where two or more 30RAP
chillers are placed in parallel. There should not be more than
one expansion tank in the system (as seen in Fig. 17) unless
manifolded together. When multiple 30RAP chillers are applied in parallel, and the chillers include the optional hydronic
package which contain expansion tanks (sizes 010-060), the
expansion tanks must be disconnected from the 30RAP hydronic package. It is permissible to install the expansion tank(s)
in a portion of the return water line that is common to all
pumps, providing that the tank is properly sized for combined
system volume.
If the application involves two or more chillers in a primary/
secondary system, a common place for mounting the
expansion tank is in the chilled water return line, just before the
decoupler. See Fig. 18 for placement of expansion tank in
primary/secondary systems.
The expansion tank included in the 30RAP hydronic package is a diaphragm tank, meaning that a flexible diaphragm
physically separates the water/air interface. With this type of
expansion tank, it is undesirable to have any air in the water
loop. See the section on air separation below for instructions on
providing air separation equipment.
AIR SEPARATION — For proper system operation, it is
essential that water loops be installed with proper means to
manage air in the system. Free air in the system can cause
noise, reduce terminal output, stop flow, or even cause pump
failure due to pump cavitation. For closed systems, equipment
should be provided to eliminate all air from the system.
The amount of air that water can hold in solution depends
on the pressure and temperature of the water/air mixture. Air is
less soluble at higher temperatures and at lower pressures.
Therefore, separation can best be done at the point of highest
water temperature and lowest pressure. Typically, this point
would be on the suction side of the pump as the water is returning from the system or terminals. Generally speaking, this is
the best place to install an air separator, if possible.
1. Install automatic air vents at all high points in the system.
(If the 30RAP unit is located at the high point of the
system, a vent can be installed on the piping entering the
heat exchanger on the Вј-in. NPT female port.)
2. Install an air separator in the water loop, at the place
where the water is at higher temperatures and lower
pressures — usually in the chilled water return piping.
On a primary-secondary system, the highest temperature
water is normally in the secondary loop, close to the
decoupler. Preference should be given to that point on the
system (see Fig. 18). In-line or centrifugal air separators
are readily available in the field.
It may not be possible to install air separators at the place of
lowest pressure and highest temperature. In such cases, preference should be given to the points of highest temperature. It is
important that pipe be sized correctly so that free air can be
moved to the point of separation. Generally, a water velocity of
at least 2 feet per second will keep free air entrained and
prevent it from forming air pockets.
Automatic vents should be installed at all physically elevated points in the system so that air can be eliminated during
system operation. Provision should also be made for manual
venting during the water loop fill. It is important that the
automatic vents be located in accessible locations for
maintenance purposes, and that they be located where they can
be prevented from freezing.

For example, assuming a system containing a 20% concentration of ethylene glycol and 50 feet (15.2 m) in height from
the top of the system to the expansion tank, the minimum tank
pre-charge pressure would be:
Tank Pressure = 4 + (50 / 2.38) = 25.0 psig
= 27.6 + (15.2 x 22.6 / 2.38) = 171.9 kPa

NOTE: If expansion tanks are placed elsewhere in the system this
method cannot be used since extra pressure drop between the tank
and the pump must be accounted for.
NOTE: If the system requires a pre-charge greater than
40 psig (276 kPa), increase pressure as described below.
Expansion Tank Pre-Charge — To pre-charge the expansion
tank, do the following steps:
1. Check the tank air pressure at the pre-charge connection
with an accurate pressure gage. Adjust as needed.
2. If additional pressure is required, charge the tank with oilfree compressed air or nitrogen gas. Occasionally check
the pressure as when filling a tire.
3. Check the air valve for leakage. If it leaks, relieve the
pressure and replace the core with a Schrader type tire
core. DO NOT depend on the valve cap to seal the leak.
Once the system is pressurized, the pressure at the connection point of the expansion tank to water piping will not change
unless the water loop volume changes (either due to addition/
subtraction of water or temperature expansion/contraction).
The pressure at this point remains the same regardless of
whether or not the pump is running.
Since the expansion tank acts as a reference point for the
pump, there cannot be two reference points (two expansion

Table 3 — Water Quality Characteristics
and Limitations
WATER SYSTEM CLEANING — Proper water system
cleaning is of vital importance. Excessive particulates in the
water system can cause excessive pump seal wear, reduce or
stop flow, and cause damage of other components. Water
quality should be maintained within the limits indicated in
Table 3. Failure to maintain proper water quality may result in
heat exchanger failure.
CAUTION
Failure to properly clean all piping and components of the
chilled water system before unit start-up may result in
plugging of the heat exchanger, which can lead to poor performance, nuisance alarms and damage from freezing.
Freezing damage caused by an improperly cleaned system
represents abuse and may impair or otherwise negatively
affect the Carrier product warranty.
1. Install a temporary bypass around the chiller to avoid circulating dirty water and particulates into the pump package and chiller during the flush. Use a temporary circulating pump during the cleaning process. Also, be sure that
there is capability to fully drain the system after cleaning.
(See Fig 19.)
2. Be sure to use a cleaning agent that is compatible with all
system materials. Be especially careful if the system
contains any galvanized or aluminum components. Both
detergent-dispersant and alkaline-dispersant cleaning
agents are available.
3. It is a good idea to fill the system through a water meter.
This provides a reference point for the future for loop
volume readings, but it also establishes the correct
quantity of cleaner needed in order to get the required
concentration.
4. Use a feeder/transfer pump to mix the solution and fill the
system. Circulate the cleaning system for the length of
time recommended by the cleaning agent manufacturer.
a. After cleaning, drain the cleaning fluid and flush the
system with fresh water.
b. A slight amount of cleaning residue in the system can
help keep the desired, slightly alkaline, water pH of 8
to 9. Avoid a pH greater than 10, since this will
adversely affect pump seal components.
c. A side stream filter is recommended (see Fig. 20)
during the cleaning process. Filter side flow rate
should be enough to filter the entire water volume
every 3 to 4 hours. Change filters as often as necessary during the cleaning process.
d. Remove temporary bypass when cleaning is
complete.

*Sulfides in the water quickly oxidize when exposed to air, requiring that
no agitation occur as the sample is taken. Unless tested immediately
at the site, the sample will require stabilization with a few drops of one
Molar zinc acetate solution, allowing accurate sulfide determination up
to 24 hours after sampling. A low pH and high alkalinity cause system
problems, even when both values are within the ranges shown. The
term pH refers to the acidity, basicity, or neutrality of the water supply.
Below 7.0, the water is considered to be acidic. Above 7.0, water is
considered to be basic. Neutral water contains a pH of 7.0.
†Dissolved carbon dioxide can either be calculated from the pH and
total alkalinity values, shown below, or measured on the site using a
test kit. Dissolved Carbon Dioxide, PPM = TA x 2[(6.3-pH)/0.3] where TA
= Total Alkalinity, PPM as CaCO3.
A 40-mesh strainer with a blow-down valve is standard on
all 30RAP units, both with and without hydronic packages.
The blow-down valve allows removal of particulates caught in
the strainer without complete removal of the screen. A female
NPT connection is provided on the valve, allowing hose connection for drainage outside the unit.
Carrier’s ComfortLink controls provided have a built-in
feature to remind building owners or operators to clean the
strainer by discharging the blow-down valve at a pre-set time
interval. Properly installed and cleaned systems will rarely
need the strainer cleaned after the initial fill. This time interval
is user-configurable.
FILLING THE SYSTEM — The initial fill of the chilled
water system must accomplish three purposes:
1. The entire piping system must be filled with water.
2. The pressure at the top of the system must be high enough
to vent air from the system (usually 4 psig [28 kPa] is adequate for most vents).
23
2. Check to make sure all drain plugs are installed.
3. Open the blow-down valve to flush the strainer.
Normally, a closed system needs to be filled only once. The
actual filling process is generally a fairly simple procedure. All
air should be purged or vented from the system. Thorough
venting at the high points and circulation at room temperature
for several hours is recommended.
NOTE: Local codes concerning backflow devices and other
protection of the city water system should be consulted and
followed to prevent contamination of the public water
supply. This is especially important when antifreeze is used
in the system.
Set Water Flow Rate — Once the system is cleaned, pressurized, and filled, the flow rate through the chiller must be established. On units with the hydronic package, this can best be
done using the balancing valve.
In order to adjust the balancing valve, put a differential
pressure gage across the pressure taps on the valve. Make sure
that all system isolation and control valves are open. Use Tables 4-7 to determine gpm.
1. Measure the pressure drop across the balancing valve. If
the pressure reading is in psig, multiply psig by 2.31 to
convert to feet of water before using Tables 4-8.
2. Go to the row in the chart corresponding to the setting on
the valve, interpolating if necessary.
3. The gpm corresponding to the pressure drop measured is
the flow through the balancing valve.
NOTE: Carrier recommends a differential pressure gage when
measuring pressures across the pumps or balancing valves.
This provides for greater accuracy and reduces error build-up
that often occurs when subtracting pressures made by different
gages.
On primary/secondary systems, it is advisable to set the
30RAP balancing valve to maintain design flow plus 10%
through the chiller.
A rough estimate of water flow can also be obtained from
the pressure gages across the 30RAP heat exchanger.
Figures 21-28 show the relationship between gpm and heat exchanger pressure drop. It should be noted that these curves are
for “clean” heat exchangers; they do not apply to heat exchangers with fouling. To read the chart, subtract the readings of the
two pressure gages on the hydronic kit. This number is the
pressure drop across the heat exchanger. Adjust the factory-installed balancing valve or external balancing valve (units without hydronic package) until the correct pressure drop is obtained for the required gpm. Total unit pressure drop is found in
Appendix A.

3. The pressure at all points in the system must be high
enough to prevent flashing in the piping or cavitation in
the pump.
The pressure created by an operating pump affects system
pressure at all points except one — the connection of the
compression tank to the system. This is the only location in the
system where pump operation will not give erroneous pressure
indications during the fill. Therefore, the best location to install
the fill connection is close to the expansion tank. An air vent
should be installed close by to help eliminate air that enters
during the fill procedure.
Ensure the following when filling the system:
1. Remove temporary bypass piping and cleaning/flushing
equipment.

Minimum Loop Volume — The minimum volume of fluid required to be in circulation is a function of the number of compressors in the chiller as well as the type of application. The
minimum fluid in circulation must equal or exceed the values
in Table 9.
To achieve this fluid volume, it is often necessary to install a
tank in the loop. The tank should be baffled to ensure there is
no stratification and that water (or brine) entering the tank is
adequately mixed with liquid in the tank. See Fig. 29.
upon loop volume, units with the integrated hydronic kit must
not exceed the maximum loop volume limits below (see
Table 10). The limits are dependent on the maximum and
minimum temperatures of the water, the maximum and
minimum pressures seen by the expansion tank, and the heat
transfer fluid. Expansion tank and maximum loop volume data
is as follows:
30RAP010-030
30RAP035-060

10.0 (37.9)
Acceptance Volume gal (L) 2.9 (11.0)
5.5 (20.8)
Pump Modification/Trimming (Units with Factory-Installed
Hydronic Package) — Since the pumps are constant speed,
the only way to obtain greater flow with a given pump/impeller
is to decrease system head. This will allow the pump to “ride”
its curve to the right, resulting in increased flow. If greater flow
is necessary, look at opening the balance valve. Also, verify
that the strainer is clean, and that no unnecessary system resistance is present, such as partially closed isolation valves.
Increasing system resistance by closing the balancing valve
will force the pump to “ride” its curve to the left, resulting in
less flow. Although this does reduce power consumption
slightly, it may not be the desirable method of reducing the
flow, especially if a rather large reduction is needed.
The other method for reducing flow on a constant speed
pump is impeller trimming. The impellers in the pumps provided in the 30RAP hydronic kit are easily removable for this purpose. Refer to the pump literature packet supplied with the
hydronic package information on Seal Replacement in the
Service Section, and follow its instructions for impeller removal. Trimming should only be done by a qualified machine shop
that has experience in this operation. Contact your local Carrier
representative for a recommended machine shop. After trimming, the impeller MUST be balanced. Failure to balance
trimmed impellers can result in excessive vibration, noise, and
premature bearing failure.
Impeller trimming has the added benefit of maximum bhp
savings. It is very possible for power savings to pay for the
trimming cost very quickly. The 30RAP pump option may be
applied with a field-supplied VFD. When applied with a VFD,
the maximum length of wiring between the drive and the pump
motor is 50 ft (15.2 m). The maximum allowable carrier frequency of the inverter is 12 kHz, with 3 kHz recommended.

Fig. 29 — Tank Baffling
The piping between the chiller and the accessory tank can
be done to allow the tank to be on the return side of the chiller
(tank piped to chiller inlet) or the supply side of the chiller
(tank piped to the chiller outlet). For standard compressors, it is
recommended that the tank be piped to the return side of the
chiller to buffer any changes in load to allow more stable chiller operation. For digital compressor applications, it is recommended that the tank be piped to the supply side of the chiller
to provide a more stable supply temperature.
A properly baffled storage tank is available from the factory
as an accessory for sizes 010-060 only. These tanks are designed to physically fit beneath the corresponding 30RAP unit,
taking up the same footprint.

NOTE: Max loop volume is based on typical system of 12 psig
(83 kPa) and 30 psig (207 kPa) of min/max pressures, and 100 F
(37.8 C) mean temperature. If the volume in the system is greater
than the limits listed, then extra expansion tank volume must be
added to the system.

2. Use an electric tape heater for the internal piping (excluding those within the pump box) if unit will be exposed to
freezing temperature.
3. Ensure that power is available to the chiller at all times,
even during the off-season, so that the pump and cooler
heaters have power. Also make sure that the piping tape
heaters have power.
4. On units with pump packages, a heater is supplied in the
pump box that will protect this section from freezing in
outdoor-air temperatures down to –20 F (–29 C), except
in case of a power failure.
5. Cooler heaters that will protect down to –20 F (–29 C)
can be installed as a factory option. It should be noted that
these heaters will not protect the cooler from freezing in
the event of a power failure.
PREPARATION FOR WINTER SHUTDOWN — Do not
shut off power disconnect during off-season shutdown. At the
end of the cooling season:
1. Drain water from system.
2. Replace drain plug(s) and add sufficient inhibited ethylene glycol (or other suitable inhibited antifreeze) to
cooler, pump and piping to prevent freezing of residual
water.
3. At the beginning of the next cooling season, refill cooler
and add recommended inhibitor.
PREPARATION FOR YEAR-ROUND OPERATION — If
the unit is in operation year-round, add sufficient suitable
inhibited antifreeze solution such as propylene or ethylene glycol to chilled water to prevent freezing under low-ambient
temperature operating conditions. Consult a local water treatment specialist on characteristics of water and recommended
inhibitor.
IMPORTANT: Glycol antifreeze solutions are highly
recommended since heater tapes provide no protection
in the event of a power failure.
MotormasterВ® low ambient temperature head pressure control is required if ambient temperatures are below 45 F (7 C) on
size 018-030 units, and 32 F (0В° C) on size 035-150 units. Motormaster control is standard on size 010 and 015 units.
Accessory wind baffles are required with Motormaster head
pressure control if the wind velocity is anticipated to be greater
than 5 mph (8 km/h). Unit sizes 010-030 require one baffle and
unit sizes 035-060 require two baffles. Unit sizes 070-150
require one baffle. See Table 11.

Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation. There
may be more than one disconnect switch. Tag all disconnect
locations to alert others not to restore power until work is
completed.
CAUTION
To avoid damage to refrigerant coils and electronic components, use extreme care when drilling screw holes and
attaching fasteners.
POWER SUPPLY — Electrical characteristics of available
power supply must agree with unit nameplate rating. Field
wiring size and supply voltage must be within limits shown in
Table 12. See Tables 13-24 for component electrical data.
FREEZE PROTECTION — The 30RAP units are provided
with a water strainer and a flow switch to protect against freezing situations that occur from no water flow. While the flow
switch (thermal dispersion) is helpful in preventing freezing
during no-flow situations, it does not protect the chiller in case
of power failure, or in other cases where water temperature
falls below the freezing mark. Appropriate concentrations of
inhibited ethylene glycol or other suitable inhibited antifreeze
solution should be considered for chiller protection where ambient temperatures are expected to fall below 32 F (0.0В° C).
Consult local water treatment specialist on characteristics of
the system water and add a recommended inhibitor to the
chilled water.
IMPORTANT: Operating unit on improper supply voltage
or with excessive phase imbalance constitutes abuse and
may affect Carrier warranty.
POWER WIRING — All power wiring must comply with
applicable local and national codes. Install field-supplied
branch circuit fused disconnect per NEC (National Electric
Code, U.S.A.) of a type can be locked OFF or ON. Disconnect
must be within sight from and readily accessible from unit in
compliance with NEC Article 440-14.
General Wiring Notes
1. The control circuit does NOT require a separate power
source. Control circuit power is obtained by a step-down
transformer from the main three-phase power supply. The
LVT (low voltage terminal) strip is provided for fieldwired control devices.
2. Cooler and pump heaters (if factory installed) are wired
in the control circuit so they are operable as long as the
main power supply to the unit and heater safety device is
ON. A factory-installed and set overload device protects
them.
NOTE: The field-supplied disconnect should never be off
except when unit is being serviced or is to be down for a prolonged period, in which case cooler should be drained. Since
all water cannot be drained completely, add an appropriate
amount of inhibited glycol as noted for winter shutdown.
3. Power entry is at the right-hand side of the unit when facing the control box.
CAUTION
Do not circulate water through unit without strainer in place.
Failure to use the strainer represents abuse and may impair
or otherwise negatively affect the Carrier product warranty.
1. If the pump will be subjected to freezing temperatures,
steps must be taken to prevent freeze damage. If the
pump will not be used during this time, it is recommended to drain the pump and hydronic package and these
components back-flushed with inhibited glycol. Otherwise, a glycol-water solution should be considered as the
heat transfer fluid. Units have a drain mounted on the piping leaving the heat exchanger. Drains are located on the
sheet metal base of all units.
NOTE: Do not use automobile antifreeze, or any other fluid
that is not approved for heat exchanger duty. Only use appropriately inhibited glycols, concentrated to provide adequate
protection for the temperature considered.
33
6. Units with high short circuit ratings and terminal block
option require that specific fuses be applied to achieve
this rating. Refer to Table 12.
4. Maximum field wire sizes allowed by lugs on terminal
block/non-fused disconnect are listed in Table 12.
5. Terminals for field power supply are suitable for
copper conductors. Insulation must be rated 167 F (75 C)
minimum.

NOTES:
1. Units are suitable for use on electrical systems where voltage supplied to
the unit terminals is not below or above the listed minimum and maximum
limits. Maximum allowable phase imbalance is: voltage, 2%; amps 10%.
2. All units/modules have single point primary power connection. (Each unit/
module requires its own power supply.) Main power must be supplied from
a field-supplied disconnect.
3. Cooler heater is wired into the control circuit so it is always operable as
long as the power supply disconnect and heater safety device are on.

4. Power draw control circuits include both crankcase heaters (sizes 070150 only) and cooler heaters (where used). Each compressor on sizes
070-090 has a crankcase heater which draws 90 watts of power, while
each compressor on sizes 100-150 has a crankcase heater which draws
56 watts of power.

— Minimum Circuit Amps
MOCP — Maximum Overcurrent Protection
NOTES:
1. Units are suitable for use on electrical systems where voltage supplied to
the unit terminals is not below or above the listed minimum and maximum
limits. Maximum allowable phase imbalance is: voltage, 2%; amps 10%.
2. All units/modules have dual point primary power connection. (Each unit/
module requires its own power supply.) Main power must be supplied from
a field-supplied disconnect.
3. Cooler heater is wired into the control circuit so it is always operable as
long as the power supply disconnect and heater safety device are on.

4. Power draw control circuits include both crankcase heaters (sizes 070150 only) and cooler heaters (where used). Each compressor on sizes
070-090 has a crankcase heater which draws 90 watts of power, while
each compressor on sizes 100-150 has a crankcase heater which draws
56 watts of power.

NOTES:
1. Units are suitable for use on electrical systems where voltage supplied to
the unit terminals is not below or above the listed minimum and maximum
limits. Maximum allowable phase imbalance is: voltage, 2%; amps 10%.
2. All units/modules have single point primary power connection. (Each unit/
module requires its own power supply.) Main power must be supplied from
a field-supplied disconnect.
3. Cooler heater is wired into the control circuit so it is always operable as
long as the power supply disconnect and heater safety device are on.

NOTES:
1. Units are suitable for use on electrical systems where voltage supplied to
the unit terminals is not below or above the listed minimum and maximum
limits. Maximum allowable phase imbalance is: voltage, 2%; amps 10%.
2. All units/modules have single point primary power connection. (Each unit/
module requires its own power supply.) Main power must be supplied from
a field-supplied disconnect.
3. Cooler heater is wired into the control circuit so it is always operable as
long as the power supply disconnect and heater safety device are on.

NOTES:
1. Units are suitable for use on electrical systems where voltage supplied to the unit terminals is not below or above the listed minimum and maximum limits. Maximum allowable phase imbalance is: voltage, 2%; amps 10%.
2. All units/modules have dual point primary power connection. (Each unit/module
requires its own power supply.) Main power must be supplied from a field-supplied
disconnect.
3. Cooler heater is wired into the control circuit so it is always operable as long as the
power supply disconnect and heater safety device are on.
4. Power draw control circuits include cooler heaters (where used).

3. Cooler heater is wired into the control circuit so it is always operable as
long as the power supply disconnect and heater safety device are on.
4. Power draw control circuits include both crankcase heaters (sizes 070150 only) and cooler heaters (where used). Each compressor on sizes
070-090 has a crankcase heater which draws 90 watts of power, while
each compressor on sizes 100-150 has a crankcase heater which draws
56 watts of power.

NOTES:
1. Units are suitable for use on electrical systems where voltage supplied to
the unit terminals is not below or above the listed minimum and maximum
limits. Maximum allowable phase imbalance is: voltage, 2%; amps 10%.
2. All units/modules have single point primary power connection. (Each unit/
module requires its own power supply.) Main power must be supplied from
a field-supplied disconnect.

4. Power draw control circuits include both crankcase heaters (sizes 070150 only) and cooler heaters (where used). Each compressor on sizes
070-090 has a crankcase heater which draws 90 watts of power, while
each compressor on sizes 100-150 has a crankcase heater which draws
56 watts of power.

MOCP — Maximum Overcurrent Protection
NOTES:
1. Units are suitable for use on electrical systems where voltage supplied to
the unit terminals is not below or above the listed minimum and maximum
limits. Maximum allowable phase imbalance is: voltage, 2%; amps 10%.
2. All units/modules have single point primary power connection. (Each unit/
module requires its own power supply.) Main power must be supplied from
a field-supplied disconnect.
3. Cooler heater is wired into the control circuit so it is always operable as
long as the power supply disconnect and heater safety device are on.

Instantaneous Current Flow
Minimum Circuit Amps
Maximum Overcurrent Protection
NOTES:
1. Units are suitable for use on electrical systems where voltage supplied to the unit terminals is not below or above the listed minimum and maximum limits. Maximum allowable phase imbalance is: voltage, 2%; amps 10%.
2. All units/modules have dual point primary power connection. (Each unit/module
requires its own power supply.) Main power must be supplied from a field-supplied
disconnect.
3. Cooler heater is wired into the control circuit so it is always operable as long as the
power supply disconnect is on, even if any safety device is open.
4. Power draw control circuits include cooler heaters (where used).

Low Ambient Operation — If outdoor ambient operating
temperatures below 45 F (7 C) on size 018-030 units or 32 F
(0В° C) on size 035-150 units are expected, refer to separate installation instructions for low-ambient operation using accessory MotormasterВ® V control. Size 010 and 015 units have Motormaster V installed as standard.
Minimum Load Accessory — If minimum load accessory is
required, refer to unit Price Pages or contact your local Carrier
representative for more details. For installation details, refer to
separate installation instructions supplied with the accessory
package.
Miscellaneous Accessories — For applications requiring special accessories, the following packages are available: external
vibration isolation, remote enhanced display, temperature reset,
hail guard/security grilles, storage tank, wind baffles, and remote cooler. For installation details, refer to separate installation instructions supplied with these accessory packages.
FIELD CONNECTIONS
Main Power — Bring wires from the fused disconnect switch
through hole in the middle of the right hand corner post to the
bottom of the control box and connect to terminals on terminal
block or non-fused disconnect. A 7/8-in. hole is provided in the
corner post to locate the center of the field power entry. To
comply with NEC Article 440-14, the disconnect must be located within sight from and readily accessible from unit. Refer
to Fig. 30.
IMPORTANT: To ensure power to the heaters, make sure
auxiliary power to the unit and the compressor circuit
breakers is always on (except for servicing or prolonged
shutdown). Since all water cannot be drained completely,
add an appropriate amount of inhibited glycol as noted for
winter shutdown.
CAUTION
Step 7 — Check Refrigerant Circuit
Proper rotation of condenser fan(s) MUST be verified
before pumps or compressors are started. Consult the Controls, Start-Up, Operation, Service and Troubleshooting
manual provided with this chiller for correct procedure.
Improper pump rotation can cause permanent damage to
pump impeller and housing. If pump(s) have been removed
for trimming, verify that wiring is reconnected in the original manner.
LEAK TESTING — Units are shipped with complete operating charge of R-410A (refer to physical data tables) and should
be under sufficient pressure to conduct a leak test. Perform a
leak test to ensure that leaks have not developed during unit
shipment. Dehydration of the system is not required unless the
entire refrigerant charge has been lost. Repair any leak found
using good refrigeration practice.
DEHYDRATION — Refer to Carrier Standard Service Techniques Manual, Chapter 1, Refrigerants, Sections 6 and 7 for
details. Do not use compressor to evacuate system.
REFRIGERANT CHARGE (Refer to Tables 1A and
1B) — Immediately after the condenser coil in each circuit is a
1/ -in. Schrader connection for charging liquid refrigerant.
4
Utilization of NovationВ® condenser coil technology enables
the 30RAP chiller to have a very low refrigerant charge. Therefore, if field charging is required, accurately charging to the
correct quantity is very important. It is necessary to ensure that
the system is completely evacuated before charging and that
the refrigerant charge is accurately weighed to within 1% of the
nameplate quantity or the unit may not operate correctly.
Control Power — Control power is obtained from the main
power supply and does NOT require a separate source. A
toggle switch (marked Emergency On-Off on the unit label
diagram and by the switch) allows the control circuit to be
manually disconnected when necessary.
Step 6 — Install Accessories
ELECTRICAL — A number of electrical accessories are
available to provide the following optional features (for details,
refer to the Controls, Start-Up, Operation, Service, and
Troubleshooting book):
Energy Management Module (Used for any of the following
types of temperature reset, demand limit and ice features):
• 4 to 20 mA leaving fluid temperature reset (requires
field-supplied 4 to 20 mA generator)
• 4 to 20 mA cooling set point reset (requires fieldsupplied 4 to 20 mA generator)
• Discrete inputs for 2-step demand limit (requires fieldsupplied dry contacts)
• 4 to 20 mA demand limit (requires field-supplied 4 to
20 mA generator)
• Discrete input for Ice Done switch (requires fieldsupplied dry contacts)
Navigator™ Display — The device provides hand-held,
mobile capability using an easy to read 4-line display. The keypad function is the same as the scrolling marquee module. A
magnet is provided for �hands free’ service of components.
CAUTION
When charging, circulate water through the cooler at all
times to prevent freezing. Freezing damage is considered
abuse and may impair or otherwise negatively affect the
Carrier warranty.
CAUTION
DO NOT OVERCHARGE system. Overcharging results
in higher discharge pressure, increased power consumption, and possible compressor damage.
The suction lines are provided with a 1/4-in. Schrader fitting
for connecting to low-side system pressure. The location of the
suction access port is shown in Fig. 31.

using the BACview keypad/display unit, press and hold
the “FN” key then press the “.” Key.
To install a BT485 terminator, push the BT485, on to the
BT485 connector located near the BACnet connector.
NOTE: The BT485 terminator has no polarity associated with
it.
To order a BT485 terminator, consult Commercial Products
i-Vu Open Control System Master Prices.
MS/TP WIRING RECOMMENDATIONS — Recommendations are shown in Tables 25 and 26. The wire jacket and UL
temperature rating specifications list two acceptable alternatives. The Halar specification has a higher temperature rating
and a tougher outer jacket than the SmokeGard specification,
and it is appropriate for use in applications where the user is
concerned about abrasion. The Halar jacket is also less likely to
crack in extremely low temperatures.
NOTE: Use the specified type of wire and cable for maximum
signal integrity.
The BACnet Communications option uses the UPC Open controller. The controller communicates using BACnet on an MS/
TP network segment communications at 9600 bps, 19.2 kbps,
38.4 kbps, or 76.8 kbps.
Wire the controllers on an MS/TP network segment in a daisy-chain configuration. Wire specifications for the cable are
22 AWG (American Wire Gage) or 24 AWG, low-capacitance,
twisted, stranded, shielded copper wire. The maximum length
is 2000 ft.
Install a BT485 terminator on the first and last controller on
a network segment to add bias and prevent signal distortions
due to echoing. See Fig. 32-34.
To wire the UPC Open controller to the BAS (Building Automation System) network:
1. Pull the screw terminal connector from the controller's
BAS Port.
2. Check the communications wiring for shorts and
grounds.
3. Connect the communications wiring to the BAS port’s
screw terminals labeled Net +, Net -, and Shield.
NOTE: Use the same polarity throughout the network
segment.
