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.
These instructions cover installation of 30RAP010-060 air-cooled
liquid chillers. Refer to Fig. 2 for model number to determine factoryinstalled options.
.
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.
INSTALLATION
Step 1 — Rig and Place the Unit
RIGGING — Preferred method for rigging is with spreader
bars from above the unit. Use hooks in lifting holes. Rig at a
single point with 4 cables or use spreader 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. 3 for unit weights.
See Fig. 4 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.
CAUTION
All panels must be in place when rigging. Damage to unit
could result.
PLACING UNIT — There must be at least 3 ft (0.9 m) for
service and for unrestricted airflow on all non-coil sides of unit,
and a minimum of 3.5 ft (1.1 m) clear air space on coil sides.
For multiple units, allow 8 ft (2.48 m) separation between units
for airflow and service.

end opposite the control panel for sizes 035 to 060. See
Fig. 5-10, depending on model.
All sizes have victaulic connections as shown in the physical data tables. 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
[1 °C] or below). Heat tapes should possess a rating for area
ambients and be covered with a suitable thickness of closedcell 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.
The water connections are copper victaulic. Any connecting
pipe to the 30RAP pump package must be of a material that
will not cause any galvanic corrosion. For this reason, galvanized steel pipe or other dissimilar metals must not be used unless joined by a dielectric coupling.
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.
MOUNTING UNIT — When unit is in proper location, use
of mounting holes in base rails is recommended for securing
unit to supporting structure, or for mounting unit on vibration
isolators if required. See Fig. 4. Fasteners for mounting unit are
field supplied. Be sure unit is level to within 1/8 in. per foot for
proper oil return to compressor.
Step 2 — Check Compressor Mounting — As
shipped, units with single compressors are held down with 4
bolts through rubber grommets. All units with tandem compresors are held down with 6 bolts per pair through grommets.
After unit is installed, verify mounting bolt torque 7 to10 ft-lb.
Step 3 — Cooler Fluid and Drain Piping Connections
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 to 030 and at the

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 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. 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 11 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 12 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

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
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 (unless manifolded together
as seen in Fig. 12). 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. 13 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 ¼-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. 13). 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

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

maintenance purposes, and that they be located where they can
be prevented from freezing.
Step 4 — Fill the Chilled Water Loop
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.
Table 3 — Water Quality Characteristics
and Limitations
WATER CHARACTERISTIC
Alkalinity (HCO3-)
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 14.)
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. 15)
during the cleaning process. Filter side flow rate
should be enough to filter the entire water volume

*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.
The Carrier ComfortLink™ controls provided have a builtin 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.

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 16A-17B 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 factoryinstalled 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.
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 the following table. See Table 6.
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. 18.
A properly baffled storage tank is available from the factory
as an accessory. These tanks are designed to physically fit
beneath the corresponding 30RAP unit, taking up the same
footprint.

Maximum Loop Volume (Units with Hydronic Package) —
Since the minimum size of the expansion tank is dependent
upon loop volume, units with the integrated hydronic kit must
not exceed the maximum loop volume limits below (see
Table 7). 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.

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 is adequate for
most vents).
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.
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 needs to 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 4A-5B or a Bell & Gossett balancing valve calculator to
determine gpm. To read Tables 4 and 5:
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 4A and 5A.
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

NOTE: Max loop volume is based on typical system of 12 psig and
30 psig of min/max pressures, and 100 F 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.
Fig. 18 — Tank Baffling
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 ITT 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.
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.
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.
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.
IMPORTANT: Glycol antifreeze solutions are highly
recommended since heater tapes provide no protection
in the event of a power failure.
Motormaster® 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 (0° C) on size 035-060 units.
Motormaster 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. See Table 8.

CAUTION
WARNING
To avoid damage to refrigerant coils and electronic components, use extreme care when drilling screw holes and
attaching fasteners.
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.
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 (0.0° C).
Consult local water treatment specialist on characteristics of
the system water and add a recommended inhibitor to the
chilled water.
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 9. See Tables 10-17 for component electrical data.
IMPORTANT: Operating unit on improper supply voltage
or with excessive phase imbalance constitutes abuse and
may affect Carrier warranty.

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 is on, even if any safety device is open.

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 is on, even if any safety device is open.

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. The unit control circuit power transformer (24 v, single-phase for all
voltages) is factory supplied.
4. Cooler heaters are wired into the main power circuit so they are
always operable as long as the disconnect is on, even if any safety
device is open, and the unit ON/OFF switch is in the OFF position.
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%.

• 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.
Low Ambient Operation — If outdoor ambient operating
temperatures below 45 F (7 C) on size 018-030 units or 32 F
(0° C) on size 035-060 units are expected, refer to separate installation instructions for low-ambient operation using accessory Motormaster® 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, remote enhanced display, temperature reset, condenser coil covers, storage tank, wind baffles, and remote cooler. For installation details, refer to separate installation instructions supplied with these accessory packages.
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 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.
3. Power entry is at the right-hand side of the unit when facing the control box.
4. Maximum field wire sizes allowed by lugs on terminal
block/non-fused disconnect are listed in Table 8.
5. Terminals for field power supply are suitable for
copper conductors. Insulation must be rated 167 F (75 C)
minimum.
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. 19.
Step 7 — Check Refrigerant Circuit
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 Novation 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.
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).
CAUTION
Proper rotation of condenser fan(s) MUST be verified
before pumps or compressors are started. Consult the Controls, Start-Up and Operation 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.
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. Cooler and pump
heaters (if installed) are in an operable state when this switch is
in the Off position.
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.
Step 6 — Install Accessories
CAUTION
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)
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. 20.
