*Charges listed are for 30HXC units. The 30HXA units are shipped
with a holding charge only. To determine the refrigerant charge
requirements for 30HXA units, see the 30HXA Estimated System
Refrigerant Charge table in the Refrigerant Charge section on

Locate valves in return and supply fluid lines as close to the
chiller as possible. Locate air vent at highest point of the cooler
fluid system. See Fig. 13.
Provide drain connections at all low points to permit
complete drainage of the system.
BRINE UNITS — Special factory modifications to the units
are required to allow them to operate at fluid temperatures less
than 34 F (1.1 C). Be sure that the fluid has sufficient inhibited
ethylene glycol or other suitable corrosion-resistant antifreeze
solution to prevent cooler freeze up. Condenser water flow
must be maintained to prevent freeze-up on unit applications
where condenser water does not contain antifreeze.
Step 2 — Rig and Place Unit
CAUTION
Rig unit from the top heat exchanger only. Rigging from
the bottom heat exchanger will cause the unit to be lifted
unsafely. Personal injury or damage to the unit may occur.
IMPORTANT: Install unit in area which will not be
exposed to ambient temperatures below 50 F (10 C).
Do not remove unit from skid until unit is in its final
location. Rig from the rigging holes provided in the top heat
exchanger. See Fig. 2-9, 11, and 12 for rigging and center of
gravity information. Lower the unit carefully onto the floor or
roller. Push or pull only on the skid, not the unit. If the unit is
moved on rollers, use a minimum of 3 evenly spaced rollers.
Areas where unit mounting points will be located must be
level to within 1/16 in. per ft (5 mm per m) along the long axis
of the unit. Once unit is in place and level, bolt unit to the floor.
Use isolation pads under the unit to aid in vibration isolation as
required.
IMPORTANT: On brine applications where leaving cooler
water is less than 34 F (1.1 C), a minimum water flow of
0.75 gpm/ton (0.14 L/s per kW) should be maintained
through the condenser at all times. In addition to the
factory-installed chilled water flow switch, a factorysupplied condenser water flow switch must be installed per
the switch manufacturer's instructions. The chiller must
control both the chilled water pump and the condenser
pump and utilize cooler and condenser pump interlocks.
The cooler pump must operate for a minimum of 10 minutes after the chiller has shut down and the condenser
pump must operate for 30 minutes after the chiller has shut
down. In the event of loss of condenser water flow, the
flow of chilled fluid to the evaporator must be stopped or
an isolation valve must be closed. Condenser head pressure
control valve must be coordinated with condenser flow
switch to ensure the minimum valve position does not prevent flow detection. This is necessary to reduce the possibility of condenser freeze-up.
Step 3 — Piping Connections — See Fig. 13, 14A,
and 14B for typical piping applications.
COOLER FLUID, VENT, AND DRAIN — The inlet (return) fluid connection is always the lower of the 2 cooler
connections. See Fig. 13 for locations. A screen strainer with a
minimum of 20 mesh must be installed ahead of the cooler
inlet (within 10 ft [3.05 m]) to prevent debris from damaging
internal tubes of the cooler. Outlet (supply) fluid connection is
the upper connection of the 2 cooler connections.
The cooler has victaulic nozzles to connect to the fieldsupplied piping. Plan the piping arrangement in accordance
with good piping practices and so that the piping does not cross
in front of the cooler head. Use flexible connections on cooler
piping to reduce vibration transmission. Offset the piping to
permit removal of the cooler head for maintenance. Install pipe
hangers where needed. Make sure no weight or stress is placed
on the water nozzle.
PREPARATION FOR YEAR-ROUND OPERATION —
In areas where the piping or unit is exposed to 32 F (0° C) or
lower ambient temperatures, freeze-up protection is recommended using inhibited ethylene glycol or other suitable
corrosion-resistant antifreeze solution and electric heater
tapes. Heater tapes should have a rating for area ambient
temperatures and be covered with a suitable thickness of
closed-cell insulation. Route power for the heater tapes from a
separately fused disconnect. Mount the disconnect within sight
from the unit per local or NEC codes. Identify disconnect as
heater tape power source with warning that power must not be
turned off except when servicing unit.
CAUTION
Cooler and condenser heads are cast iron. Welding is not
recommended. In the event that welding must be performed, remove the chilled water flow switch and entering
and leaving fluid thermistors before welding. Reinstall flow
switch and thermistors after welding is complete. Failure to
remove these devices may cause component damage.
IMPORTANT: Use of electric heat will not prevent freeze
up in the event of a power failure.
FILL FLUID LOOP — Fill the fluid loop with water (or antifreeze solution) and a corrosion-resistant inhibitor suitable for
the water of the area. Consult the local water authority for characteristics of area water and a recommended inhibitor for the
cooler fluid loop. Also see 30HXA Low-Ambient Considerations section on page 22.
A drain connection is located at the bottom of the cooler
head. See Fig. 2-9 for connection location. Install shutoff
valves to the drain line before filling the system with fluid.
INSULATE COOLER HEADS — Once the cooler water
lines and drain and vent lines have been installed and checked
for leaks, insulate the cooler heads with a suitable thickness of
closed-cell insulation. This will minimize the amount of condensation that forms on the cooler heads. When insulating the
cooler heads, allow for service access and removal of heads.
1. The cooler flow switch (CWFS) is factory installed in the
inlet nozzle and wired. If a cooler pump interlock is used,
the contacts must be wired to TB5. Refer to unit wire
diagrams.
IMPORTANT: Loss of flow protection is required for all
30HX chillers.
2. Provide openings in fluid piping for pressure gages and
thermometers (if used). These openings should be 5 to
10 pipe diameters from the unit water nozzles. For
thorough mixing and temperature stabilization, wells in
the leaving fluid pipe should extend at least 2 in. (50 mm)
into the pipe.
Although cooler has an air vent, it is recommended that a
field-supplied air vent be installed in the system to facilitate
servicing. Field-supplied shut-off and balancing valves should
also be installed to facilitate servicing and flow balancing.
IMPORTANT: Before starting the unit, be sure all of the air
has been purged from the system.

valve when brazing discharge line to avoid damaging the
valve. Liquid line solenoid valves with manual lift stems
should be installed between the field-supplied liquid line filter
driers and the unit. For proper electrical connections see
Fig. 18.
If valves are installed in the liquid lines, it is recommended
that field-supplied pressure relief valves be installed in each
liquid line and the pressure setting should be 320 psig
(2205 kPa). Most local codes require that the relief valves be
vented directly outdoors. The vent must not be smaller than the
relief valve outlet.
30HXA Low-Ambient Considerations — In installations
where outdoor ambient temperatures may be below 34 F
(1.1 C), it is recommended that inhibited ethylene glycol or
other suitable corrosion-resistant antifreeze solution be used in
the cooler loop to prevent cooler freeze-up.
If a suitable antifreeze solution is not used in the cooler
loop, chilled water pump control is required. The chiller will
automatically start the chilled water pump if the saturated suction temperature is less than the brine freeze point minus 6° F
(3.3° C) or if the entering or leaving water temperature is less
than the brine freeze point plus 2° F (1.1° C). Maintaining flow
through the cooler is required for freeze protection.
Fan-Cycling Pressure Switches (09DK Condensers) — In
order to provide proper head-pressure control in 30HXA units,
install fan-cycling pressure switches in each circuit in the liquid
line between the separate condenser unit and expansion device.
Two switches are shipped from the factory with the 30HXA
units. Refer to the 09DK condenser installation literature for
details on the location and installation of the switches. Since
the 30HXA is an HFC-134a unit, switch selection is based on
R-134a refrigerant pressures.
NOTES: The switches that are standard with the 09DK condensers are designed for R-22 operation and must not be used.
Instead use the switches shipped with the chiller (Part No.
HK02YB097). Switches open at 97 psig (± 10 psi), and close
at 185 psig (± 10 psi).
Back-Pressure Valve, 30HXA Units (See Fig. 19 and 20) —
The 30HXA back-pressure valves are supplied with an integral
mounting flange. The valves mount on the 30HXA oil separator. This reduces brazing when installing the discharge piping,
and allows the installer to orient the valve in any desired
position.

30HXA PIPING, VALVE, AND FAN CYCLING PRESSURE SWITCH INSTALLATION
Relieve Pressure and Recover Refrigerant — The 30HXA
units are shipped from the factory with a holding charge of
nitrogen or R-134a. Before opening the refrigerant system, relieve system pressure and recover system refrigerant through
the access fitting on the cooler.
30HXA Refrigerant Piping (See Fig. 14A and 14B) — When
running the refrigerant piping from the 30HXA unit to the
remote condenser(s), avoid excessive pressure drops. Minimizing line pressure drop is critical to the proper operation of the
unit expansion device. Refer to Tables 2 and 3 for refrigerant
line sizing guidance. The pressure drop using R-134a refrigerant is different than when using R-22 refrigerant. See Tables 4
and 5 for an example of a 2 F (1.1 C) pressure drop in saturated
temperature in the discharge (hot gas) line and liquid line, respectively. Refer to Fig. 15 and 16 for line sizing information
for the discharge and liquid lines for 30HXA (R-134a) units.
See Fig. 17 for double discharge riser details.

Complete the steps below to install the flanged backpressure valves on the 30HXA chiller before running discharge
piping. Follow these steps for both refrigerant circuits.
1. Be sure to remove nitrogen charge or properly recover refrigerant charge before removing the blank-off plate. Remove the blank-off plate from the mating flange on top of
the oil separator by removing the screws from the flange.
See Fig. 19 for location.
2. Using the screws that were removed in Step 1, bolt the
flanged back-pressure valve to the mating flange on top
of the oil separator. An O-ring is included in the box with
the back-pressure valve for sealing the flange.
The valve may be oriented in any desired position in order to make discharge piping easier. Install pipe hangers
where needed. Make sure no weight or stress is placed on
the back-pressure valve.
3. Once the back-pressure valve has been mounted to the
mating flange, and the piping is properly supported, a

An inverted trap should be installed in the discharge line at
the condenser to prevent refrigerant from flowing back to the
oil separator and compressor during unit shutdown. The inverted trap must extend to the height of the condenser. The
discharge line must be brazed to the back-pressure valve located on the top of the oil separator. Be sure to wrap back-pressure

to the 1/4-in. SAE flare fitting on the motor cooling line.
The equalizer line must be installed in order for the unit to
function properly.
NOTE: A ball valve can be installed in the equalizer line
to facilitate servicing.
4. After mounting the back-pressure valve to the unit, properly supporting it, and running the 1/4-in. equalizer line,
the discharge piping may be installed.
5. Repeat Steps 1-4 for the other refrigerant circuit.
connections on the condenser piping to reduce vibration transmission. Offset the piping to permit condenser head removal
for maintenance purposes. Install pipe hangers where needed.
Make sure no weight or stress is placed on the water nozzle.
IMPORTANT: Be sure that any Schrader core installed in
the fittings is removed prior to equalizer line installation.
Failure to remove core will result in the unit not functioning properly.
Provide openings in water piping for pressure gages and
thermometers (if used). These openings should be 5 to 10 pipe
diameters from the unit water nozzles. For thorough mixing
and temperature stabilization, wells in the leaving water pipe
should extend at least 2 in. (50 mm) into the pipe.
Although condenser has an air vent, it is recommended that
a field-supplied air vent be installed in the system to facilitate
servicing. Field-supplied shut-off and balancing valves should
also be installed to facilitate servicing and flow balancing.
Locate valves in inlet and outlet lines as close to the chiller as
possible. Locate air vents at the highest point of the system
loop. See Fig. 13.
Provide drain connections at all low points in the loop to
permit complete system drainage.
CAUTION
Remove any sensors on the condenser nozzles before
welding connecting piping. Reinstall after welding is
complete. Failure to remove these devices may cause unit
damage. Heads are cast iron, welding is not recommended.
The 30HXA206-271 machines have 2 back pressure valves
on circuit A. The equalizer line should connect to the 1/4-in.
NPT ports on each valve then tee together and run to the 1/4-in.
SAE flare tee provided in the circuit A economizer transducer
connection. The discharge piping from each valve should tee
together as close to the machine as possible. See Fig. 20.
Evacuation and Dehydration — Because the 30HXA systems
use polyolester oil, which can absorb moisture, it is important
to minimize the amount of time that the system interior is left
exposed to the atmosphere. Minimizing the exposure time of
the oil to the atmosphere will minimize the amount of moisture
that needs to be removed during evacuation.
Once all of the piping connections are complete, leak test
the unit and then pull a deep dehydration vacuum. Connect the
vacuum pump to the charging valve at the bottom of the cooler
and to the liquid line service valve. For best results, it is recommended that a vacuum of at least 500 microns (0.5 mm Hg) be
obtained. Afterwards, to ensure that no moisture is present in
the system, perform a standing vacuum-rise test.
With the unit in deep vacuum (500 microns or less), isolate
the vacuum pump from the system. Observe the rate-of-rise of
the vacuum in the system. If the vacuum rises by more than
50 microns in a 30-minute time period, then continue the
dehydration process. Maintain a vacuum on the system until
the standing vacuum requirement is met. This will ensure a dry
system.
By following these evacuation and dehydration procedures,
the amount of moisture present in the system will be
minimized. It is required that replaceable core liquid line filter
driers be installed between the condenser(s) and the expansion
devices to capture any foreign debris and provide additional
moisture removal capacity. Be sure to consider the pressure
drop of the filter drier when determining piping requirements.
The factory-supplied strainer may be removed to reduce
pressure drop provided the filter drier is located as close to the
unit as possible.
For further 30HXA piping instructions, proceed to the
section titled Install Pressure Relief Refrigerant Vent Piping.
30HXC PIPING AND VALVE INSTALLATION
30HXC Condenser Connections — The inlet fluid connection is always the lower of the 2 condenser connections. A
screen strainer with a minimum of 20 mesh must be installed
ahead of the condenser inlet (within 10 ft [3.05 m]) to prevent
debris from damaging the internal condenser tubes.
The outlet water connection is the upper connection of the
2 connections. The condenser has victaulic nozzles to connect
field-supplied piping. Plan the piping arrangement in accordance with good piping practices and so that the piping does
not cross in front of the condenser head. Use flexible
IMPORTANT: Before starting the unit, be sure all of the air
has been purged from the system.
30HXC Condenser Temperature Regulating Valve — For
installations where entering condensing water temperature
could be below 70 F (21.1 C), a field-supplied leaving water
temperature regulating valve is required. Operation below 70 F
(21.1 C) without this valve may cause the unit to shut down on
low oil pressure alarms.
NOTE: This valve should be a temperature-controlled valve
(DO NOT USE a pressure-controlled valve) which controls to
80 F (26.7 C) leaving water temperature. A valve that can be
controlled by a 4 to 20 mA signal is also supported by the
ComfortLink™ control system. Figure 21 shows the installation details for the regulating valve.
IMPORTANT: A separate, field-supplied power supply
must be used with the 4 to 20 mA valve. Failure to use a
separate power supply may result in damage to the electronic chiller components.
IMPORTANT: On brine applications where leaving cooler
water is less than 34 F (1.1 C), a minimum water flow of
0.75 gpm/ton (0.14 L/s per kW) should be maintained
through the condenser at all times.
INSTALL PRESSURE RELIEF REFRIGERANT VENT
PIPING — The low side relief valves on all units are provided
with 3/4-in. female NPT connections, and are located on top of
the cooler shell. See Fig. 2-9. There are 2 relief valves for
the cooler; one on each circuit. Make the vent connection to
the low side relief valve by installing a male NPT to copper
OD braze adapter. Braze a 90-degree short-radius elbow
to the adapter. This will allow enough space to make vent
connections to the elbow.
The 30HXA high side relief valves are provided with a
5/ -in. SAE (Society of Automotive Engineers, U.S.A.) flare

connection. The 30HXC high side relief valves are provided
with a 3/4-in. female NPT flare connection, and are located on
the bottom of the condenser shell.

Fig. 20 — 30HXA206-271 Back Pressure Valve Equalizer Line Connection (Circuit A)
type that can be locked off or open. Disconnect(s) must be
located within sight and readily accessible from the unit in
compliance with NEC Article 440-14. See Tables 6A and 6B
for unit electrical data. See Tables 7A and 7B for compressor
electrical data.
There are 2 relief valves for the oil separator (30HXA) or
condenser (30HXC); one for each circuit. Most local codes
require that these devices be piped to the outside. If vent piping
is required by local codes, these connections have been provided to aid in the connection of vent piping in accordance with
ASHRAE 15 (American Society of Heating, Refrigeration, and
Air Conditioning Engineers), Safety Code for Mechanical
Refrigeration. If vent piping is required, do not restrict the vent
flow in any way.
NOTE: When accessory suction service valve kit is installed,
there is one additional high-side pressure relief valve per
compressor. These are located on the discharge line between
the muffler and the discharge shut-off valve. Pipe these valves
per local codes.
IMPORTANT: The 30HX units have a factory-installed
option available for a non-fused disconnect for unit power
supply. If the unit is equipped with this option, all field
power wiring should be made to the non-fused disconnect
since no terminal blocks are supplied.
All units have a single location for power entry to simplify
the field power wiring. The maximum wire size that the unit
terminal block or non-fused disconnect will accept is 500 kcmil
(except units equipped with 250 amp non-fused disconnects
which will accept a maximum wire size of 300 kcmil).
All units require at least one field-supplied power supply.
Refer to Fig. 18 for a list of units that require 2 field-supplied
power supplies. Units that require 2 power supplies are listed
under TB1B in the Standard Power and Non-Fused Disconnect
Option sections of Fig. 18.
Step 4 — Make Electrical Connections — The electrical characteristics of the available power supply must agree
with the unit nameplate rating. Supply voltage must be within
the limits shown.
FIELD POWER CONNECTIONS (See Fig. 18) — All power
wiring must comply with applicable local and national codes.

FIELD CONTROL POWER CONNECTIONS (See
Fig. 18) — Units with a power supply of 230 (60 Hz),
208/230, 460, 575-3-60, require a separate 115-1-60 control
circuit power supply. Units with a 380/415-3-50 power supply
have factory pre-wired 230-1-50 control circuit power. A
separate power supply is NOT required for these units. All
other units require a separate 230 v control circuit power supply. Field control power connections are made at terminals 1
and 2 of TB4.
NOTE: Units with a 380/415 v main power supply do NOT
require a separate field-supplied control power supply. These
units have factory pre-wired control power.
Terminals TB5-1 and TB5-2 are provided for field installation of a chilled water (fluid) pump interlock (CWPI). Contacts
must be capable of handling a 24-vac load up to 50 mA.
An accessory remote on-off switch can be wired into
TB5-13 and TB5-14. See Fig. 18 for remote on-off and CWPI
wiring. Contacts must be capable of handling a 24-vac to
50 mA.
CAUTION
Do not use interlocks or other safety device contacts
connected between TB5 terminals 13 and 14 as remote
on-off. Connection of safeties or other interlocks between
these 2 terminals will result in an electrical bypass if the
enable-off-remote contact switch is in the Enable position.
If remote on-off unit control is required, a field-supplied
relay must be installed in the unit control box and wired as
shown in Fig. 18. Failure to wire the remote on-off as
recommended will result in tube freeze damage.
Terminals 11 and 12 of TB5 have been provided for a
field-supplied remote alarm (ALM). If an audible alarm is
installed, an alarm shutoff is also recommended. Power for a
field-supplied relay coil is factory-supplied but is limited to
75-va sealed, 360-va inrush. See Fig. 18.
Terminals 10 and 12 of TB5 have been provided for a
field-supplied chilled water (fluid) pump relay (CWP). Power
for the field-supplied relay coil is factory supplied, but is
limited to 75-va sealed and 360-va inrush. See Fig. 18.

low-ambient operation using accessory Motormaster® V control minimum load accessories also required.
MINIMUM LOAD ACCESSORY — If minimum load accessory is required, use the appropriate package. 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: control power transformer, sound reduction enclosure,
sound blanket, external vibration isolation, expanded display,
and temperature reset sensor. Refer to individual accessory
installation instructions for installation details.
Terminals 7 and 9 of TB2 has been provided for a
field-supplied circuit A fan control relay for the remote
condenser (30HXA) or a condenser pump relay (30HXC). Use
relays with a maximum coil rating of 75-va. Terminals 8 and 9
of TB2 have been provided for a field-supplied circuit B fan
control relay for a remote condenser (30HXA only). Use relays
with a coil rating of 75-va. A separate field power supply is
NOT required. Maximum load allowed for the fan/condenser
pump relays is 75-va sealed, 360-va inrush at 115 or 230 volts.
See Fig. 18.
CONDENSER FAN CONTROL FOR CONDENSER
UNITS USED WITH 30HXA UNITS — The main base
board provides 2 control outputs for energizing and deenergizing remote fan contactors. If desired, wire the circuit A main
fan contactor between terminals 7 and 9 of TB2. The circuit B
main fan contactor may be wired between terminals 8 and 9 of
TB2. This will cause the main fans to be on when the compressors are on. Refer to Fig. 18 for wiring details.

There are several O-ring face seal fittings used in the
refrigerant and lubrication piping. If a leak is detected at any of
these fittings, tighten the O-ring face seal nut to 85 to 118 in.-lb
(9.5 to 12.4 Nm). Always use a back up wrench when tightening the O-ring face seal nut.
30HXC UNITS — These units are shipped from the factory
with a full charge of R-134a or a nitrogen holding charge (see
Tables 1A and 1B). 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.
30HXA UNITS — These units are shipped with a holding
charge of R-134a or nitrogen. Leak test and dehydrate the complete system (including both field and factory-installed piping).
NOTE: Proper dehydration of 30HXA units is important to
ensure that no moisture is left in the system. Refer to the

LEGEND
— Maximum Instantaneous Current Flow during start-up (the
point in the starting sequence where the sum of the LRA for
the start-up compressor, plus the total RLA for all running
compressors is at a maximum)
LRA
— Locked Rotor Amps
MCA — Minimum Circuit Ampacity (for wire sizing)
MOCP — Maximum Overcurrent Protection
RLA
— Rated Load Amps
WD
— Wye-Delta Start
XL
— Across-the-Line Start
2. Control circuit power must be supplied from a separate source
through a field-supplied disconnect (except for 380/415-50 units). An
accessory control transformer may be used to provide control circuit
power from the main unit power supply.
3. Maximum incoming wire size for each terminal block is 500 kcmil.
4. Maximum allowable phase imbalance is: voltage, 2%; amps, 5%.
5. Use copper conductors only.
6. The MOCP is calculated as follows:
MOCP = (2.25) (largest RLA) + the sum of the other RLAs. Size the
fuse one size down from the result. The RLAs are listed on the nameplate.
NOTES:
1. Each main power source must be supplied from a field-supplied fused
electrical service with a (factory-installed or field-installed) disconnect
located in sight from the unit.
The recommended fuse size in amps (RFA) is calculated as follows:
RFA = (1.50) (largest RLA) + the sum of the other RLAs. Size the fuse
one size up from the result. The RLAs are listed on the nameplate.

2. Control circuit power must be supplied from a separate source
through a field-supplied disconnect (except for 380/415-50 units). An
accessory control transformer may be used to provide control circuit
power from the main unit power supply.
3. Maximum incoming wire size for each terminal block is 500 kcmil.
4. Maximum allowable phase imbalance is: voltage, 2%; amps, 5%.
5. Use copper conductors only.
6. The MOCP is calculated as follows:
MOCP = (2.25) (largest RLA) + the sum of the other RLAs. Size the
fuse one size down from the result. The RLAs are listed on the nameplate.
The recommended fuse size in amps (RFA) is calculated as follows:
RFA = (1.50) (largest RLA) + the sum of the other RLAs. Size the fuse
one size up from the result. The RLAs are listed on the nameplate.
ICF
NOTES:
1. Each main power source must be supplied from a field-supplied fused
electrical service with a (factory-installed or field-installed) disconnect
located in sight from the unit.

the cooler. This fitting is located between the EXV and
the cooler.
4. Check for a clear sight glass. If the unit is not fully
loaded, the sight glass may be flashing. This condition is
normal for a partially loaded unit. If the unit is fully
loaded and the sight glass is flashing, check EXV position. If it is greater than 60% add additional charge.
Step 7 — Refrigerant Charge
IMPORTANT: These units are designed for use with
R-134a only. DO NOT USE ANY OTHER REFRIGERANT in these units without first consulting your Carrier
representative.
NOTE: The liquid charging method is recommended for
complete charging or when additional charge is required.
Table 8 — Cooler Refrigerant Storage Capacity
CAUTION

When charging, circulate water through the condenser and
cooler at all times to prevent freezing. Freezing damage is
considered abuse and may void the warranty.

CAUTION

DO NOT OVERCHARGE system. Overcharging results
in higher discharge pressure with higher cooling fluid
consumption, possible compressor damage, and higher
power consumption.

30HXC UNITS — The 30HXC units are shipped from the
factory with a full charge of R-134a. Unit should not need
to be charged at installation unless a leak was detected in
Step 6 — Leak Test Unit section. If dehydration and recharging
is necessary, use industry standard practices or refer to Standard Services Techniques Manual or the Controls, Start-Up,
Operation, Service, and Troubleshooting Guide as required.
30HXA UNITS — The 30HXA units are shipped with a
holding charge of R-134a or nitrogen. The complete charge for
the 30HXA, the remote condenser(s), and interconnecting
piping must be field supplied.
To charge the 30HXA systems:
1. An initial refrigerant charge must be added after
evacuation to allow the unit to start. Add approximately
2 lb per nominal ton (0.26 kg per nominal kW) liquid refrigerant charge to the condenser. This amount of charge
should be sufficient to allow the unit to start. The cooler
refrigerant capacity is shown in Tables 8 and 9, approximate system charge is shown in Table 10.
2. Raise the compressor discharge pressure to approximately 185 psig (1276 kPa) (125 F [51.7 C] saturated condensing temperature) by throttling the condenser air (or
water) intake.
3. Add liquid charge into the cooler until there is approximately 18 to 20 F (10.0 to 11.1 C) of system subcooling
(saturated condensing temperature minus actual liquid
line temperature entering the electronic expansion valve
[EXV]). When adding charge, use the 1/4-in. Schradertype fitting located on the tube going into the bottom of
