Hermetic Centrifugal Liquid Chillers
with HFC-134a
Installation Instructions
SAFETY CONSIDERATIONS
NEVER APPLY an open flame or live steam to a refrigerant cylinder.
Centrifugal liquid chillers are designed to provide safe
and reliable service when operated within design speci-
fications. When operating this equipment, use good judg-
ment and safety precautions to avoid damage to equip-
ment and property or injury to personnel.
Be sure you understand and follow the procedures and
safety precautions contained in the machine instruc-
tions, as well as those listed in this guide.
Dangerous over pressure can result. When it is necessary to heat re-
frigerant, use only warm (110 F [43 C]) water.
DO NOT REUSE disposable (nonreturnable) cylinders or attempt to
refill them. It is DANGEROUS AND ILLEGAL. When cylinder is emp-
tied, evacuate remaining gas pressure, loosen the collar, and unscrew
and discard the valve stem. DO NOT INCINERATE.
CHECK THE REFRIGERANT TYPE before adding refrigerant to the
machine. The introduction of the wrong refrigerant can cause
machine damage or malfunction.
Operation of this equipment with refrigerants other than those cited
herein should comply with ANSI/ASHRAE15 (latest edition). Contact
Carrier for further information on use of this machine with other
refrigerants.
DO NOT ATTEMPT TO REMOVE fittings, covers, etc., while
machine is under pressure or while machine is running. Be sure pres-
sure is at 0 psig (0 kPa) before breaking any refrigerant connection.
CAREFULLY INSPECT all relief valves, rupture discs, and other
relief devices AT LEAST ONCE A YEAR. If machine operates
in a corrosive atmosphere, inspect the devices at more frequent
intervals.
DO NOT ATTEMPT TO REPAIR OR RECONDITION any
relief valve when corrosion or build-up of foreign material (rust, dirt,
scale, etc.) is found within the valve body or mechanism. Replace the
valve.
DO NOT VENT refrigerant relief devices within a building. Outlet from
rupture disc or relief valve must be vented outdoors in accordance with
the latest edition of ANSI/ASHRAE 15 (American National Standards
Institute/American Society of Heating, Refrigeration and Air-Conditioning
Engineers) (Safety Code for Mechanical Refrigeration). The accumu-
lation of refrigerant in an enclosed space can displace oxygen and cause
asphyxiation.
PROVIDE adequate ventilation in accordance with ANSI/
ASHRAE 15, especially for enclosed and low overhead spaces. Inha-
lation of high concentrations of vapor is harmful and may cause heart
irregularities, unconsciousness, or death. Intentional misuse can be fa-
tal. Vapor is heavier than air and reduces the amount of oxygen avail-
able for breathing. Product causes eye and skin irritation. Decompo-
sition products are hazardous.
DO NOT USE OXYGEN to purge lines or to pressurize a machine for
any purpose. Oxygen gas reacts violently with oil, grease, and other
common substances.
DO NOT install relief devices in series or backwards.
USE CARE when working near or in line with a compressed spring.
Sudden release of the spring can cause it and objects in its path to act
as projectiles.
DO NOT USE air to leak test. Use only refrigerant or dry nitrogen.
NEVER EXCEED specified test pressures. VERIFY the allowable test
pressure by checking the instruction literature and the design pressures
on the equipment nameplate.
DO NOT VALVE OFF any safety device.
BE SURE that all pressure relief devices are properly installed and func-
tioning before operating any machine.
RISK OF INJURY OR DEATH by electrocution. High voltage is present
on motor leads even though the motor is not running when a solid state
or inside-delta mechanical starter is used. Open the power supply dis-
connect before touching motor leads or terminals.
DO NOT STEP on refrigerant lines. Broken lines can whip about and
release refrigerant, causing personal injury.
DO NOT climb over a machine. Use platform, catwalk, or staging. Fol-
low safe practices when using ladders.
USE MECHANICAL EQUIPMENT (crane, hoist, etc.) to lift or move
inspection covers or other heavy components. Even if components are
light, use mechanical equipment when there is a risk of slipping or
losing your balance.
BE AWARE that certain automatic start arrangements CAN ENGAGE
THE STARTER, TOWER FAN, OR PUMPS. Open the disconnect ahead
of the starter, tower fan, and pumps. Shut off the machine or pump
before servicing equipment.
USE only repaired or replacement parts that meet the code require-
ments of the original equipment.
DO NOT VENT OR DRAIN waterboxes containing industrial brines,
liquid, gases, or semisolids without the permission of your process con-
trol group.
DO NOT LOOSEN waterbox cover bolts until the waterbox has been
completely drained.
DO NOT WELD OR FLAMECUT any refrigerant line or vessel until
all refrigerant (liquid and vapor) has been removed from chiller. Traces
of vapor should be displaced with dry air or nitrogen and the work area
should be well ventilated. Refrigerant in contact with an open flame
produces toxic gases.
DO NOT USE eyebolts or eyebolt holes to rig machine sections or the
entire assembly.
DO NOT work on high-voltage equipment unless you are a qualified
electrician.
DO NOT WORK ON electrical components, including control
panels, switches, starters, or oil heater until you are sure ALL POWER
IS OFF and no residual voltage can leak from capacitors or solid-state
components.
DOUBLE-CHECK that coupling nut wrenches, dial indicators, or other
items have been removed before rotating any shafts.
DO NOT LOOSEN a packing gland nut before checking that the nut
has a positive thread engagement.
PERIODICALLY INSPECT all valves, fittings, and piping for corro-
sion, rust, leaks, or damage.
PROVIDE A DRAIN connection in the vent line near each pressure
relief device to prevent a build-up of condensate or rain water.
LOCK OPEN AND TAG electrical circuits during servicing. IF WORK
IS INTERRUPTED, confirm that all circuits are deenergized before
resuming work.
AVOID SPILLING liquid refrigerant on skin or getting it into the eyes.
USE SAFETY GOGGLES. Wash any spills from the skin with soap
and water. If liquid refrigerant enters the eyes, IMMEDIATELY FLUSH
EYES with water and consult a physician.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

To Rig Compressor
NOTE: The motor end of the 19XR compressor is heavy
and will tip backwards unless these directions are followed:
1. Cut two 4 in. × 6 in. wooden beams to the same length
as the compressor.
2. Drill holes into the beams and bolt them to the base of
the compressor.
Additional Notes
1. Use silicon grease on new O-rings when refitting.
2. Use gasket sealant on new gaskets when refitting.
INSTALL ACCESSORY ISOLATION (if required) — Un-
even floors or other considerations may dictate the use of
accessory soleplates (supplied by Carrier for field installa-
tion) and leveling pads. Refer to Fig. 10 and 12.
Level machine by using jacking screws in isolation sole-
plates. Use a level at least 24-in. (600 mm) long.
For adequate and long lasting machine support, proper grout
selection and placement is essential. Carrier recommends that
only pre-mixed, epoxy type, non-shrinking grout be used for
machine installation. Follow manufacturer’s instructions in
applying grout.
1. Check machine location prints for required grout
thickness.
3. Cooler and condenser vessels may be rigged vertically.
Rigging should be fixed to all 4 corners of the tube sheet.
2. Carefully wax jacking screws for easy removal from grout.
3. Grout must extend above the base of the soleplate and
there must be no voids in grout beneath the plates.
4. Allow grout to set and harden, per manufacturer’s in-
structions, before starting machine.
Install Machine Supports
INSTALL STANDARD ISOLATION — Figures 10 and 11
show the position of support plates and shear flex pads, which
together form the standard machine support system.
5. Remove jacking screws from leveling pads after grout has
hardened.

INSTALL SPRING ISOLATION — Spring isolation may
be purchased as an accessory from Carrier for field instal-
lation. It may also be field supplied and installed. Spring iso-
lators may be placed directly under machine support plates
or located under machine soleplates. See Fig. 13. Consult
job data for specific arrangement. Low profile spring isola-
tion assemblies can be field supplied to keep the machine at
a convenient working height.
Obtain specific details on spring mounting and machine
weight distribution from job data. Also, check job data for
methods to support and isolate pipes that are attached to spring
isolated machines.

2. Provide openings in water piping for required pressure
gages and thermometers. For thorough mixing and tem-
perature stabilization, wells in the leaving water pipe should
extend inside pipe at least 2 in. (50 mm).
3. Install air vents at all high points in piping to remove air
and prevent water hammer.
Connect Piping
INSTALL WATER PIPING TO HEAT EXCHANGERS —
Install piping using job data, piping drawings, and proce-
dures outlined below. A typical piping installation is shown
in Fig. 14.
4. Install pipe hangers where needed. Make sure no weight
or stress is placed on waterbox nozzles or flanges.
5. Water flow direction must be as specified in Fig. 15-18.
Factory-supplied insulation is not flammable but can be
damaged by welding sparks and open flame. Protect in-
sulation with a wet canvas cover.
NOTE: Entering water is always the lower of the 2 nozzles.
Leaving water is always the upper nozzle for cooler or
condenser.
6. Water flow switches must be of vapor-tight construction
and must be installed on top of pipe in a horizontal run
and at least 5 pipe diameters from any bend.
Remove chilled and condenser water sensors before
welding connecting piping to water nozzles. Refer to
Fig. 9. Replace sensors after welding is complete.
7. Install waterbox vent and drain piping in accordance with
3
individual job data. All connections are ⁄4-in. FPT.

4.0 Low voltage (600 v or less) compressor motors have (6) 3
in. terminal
⁄4
studs (lead connectors not supplied by Carrier). Either 3 or 6 leads
must be run between compressor motor and starter, depending on type
of motor starter employed. If only 3 leads are required, jumper motor
terminals as follows: 1 to 6, 2 to 4, 3 to 5. Center to center distance
between terminals is 215⁄16 inches. Compressor motor starter must have
nameplate stamped as conforming with Carrier requirement Z-375.

motor terminals 1, 2 & 3 in one conduit, and those to 4, 5 & 6 in
another.)
4.2 Compressor motor power connections can be made through top, top
rear, or sides of compressor motor terminal box using holes cut by con-
tractor to suit conduit. Flexible conduit should be used for the last few
feet to the terminal box for unit vibration isolation. Use of stress cones
or 12 conductors larger than 500 MCM may require an oversize (spe-
cial) motor terminal box (not supplied by Carrier). Lead connections
between 3-phase motors and their starters must not be insulated until
Carrier personnel have checked compressor and oil pump rotations.
4.3 Compressor motor frame to be grounded in accordance with the Na-
tional Electrical Code (NFPA-70) and applicable codes. Means for ground-
ing compressor motor is a pressure connector for No. 4 to 500 MCM

Connect Power Wires to Oil Heater Contactor — Connect
control power wiring between the oil heater contactor ter-
minals and terminals LL1 and LL2 on the field wiring strip
in the compressor motor starter. Refer to Fig. 31 and wiring
label on the machine power panel.
The negative pins must be wired to the negative pins. The
signal ground pins must be wired to the signal ground pins.
See Fig. 24 for location of the CCN network connector
(COMM1) on the processor module.
NOTE: Conductors and drain wire must be 20 AWG
(American Wire Gage) minimum stranded, tinned copper. In-
dividual conductors must be insulated with PVC, PVC/
nylon, vinyl, Teflon, or polyethylene. An aluminum/polyester
100% foil shield and an outer jacket of PVC, PVC/nylon,
chrome vinyl, or Teflon with a minimum operating tempera-
ture range of −4 F to 140 F (−20 C to 60 C) is required. See
table below for cables that meet the requirements.
Voltage to terminals LL1 and LL2 comes from a con-
trol transformer in a starter built to Carrier specifica-
tions. Do not connect an outside source of control power
to the compressor motor starter (terminals LL1 and LL2).
An outside power source will produce dangerous volt-
age at the line side of the starter, because supplying volt-
age at the transfomer secondary terminals produces in-
put level voltage at the transformer primary terminals.
