ONLY QUALIFIED Electrical Personnel familiar with the construction
and operation of this equipment and the hazards involved should install,
adjust, operate, or service this equipment.
READ AND UNDERSTAND this manual and other applicable manuals in
their entirety before proceeding. Failure to observe this precaution could
result in severe bodily injury or loss of life.
DO NOT install modification kits with power applied to the drive. Discon-
nect and lock out incoming power before attempting such installation or
removal. Failure to observe this precaution could result in severe bodily
injury or loss of life
UNUSED WIRES in conduit must be grounded at both ends to avoid a
possible shock hazard caused by induced voltages. Also, if a drive sharing
a conduit is being serviced or installed; all drives using this conduit should

motor leads. Failure to observe these precautions could result in bodily
injury.
DO NOT VENT refrigerant relief valves 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 Insti-
tute/American Society of Heating, Refrigerating, and Air Conditioning
Engineers). The accumulation of refrigerant in an enclosed space can dis-
place oxygen and cause asphyxiation.
PROVIDE adequate ventilation in accordance with ANSI/ASHRAE 15,
especially for enclosed and low overhead spaces. Inhalation of high con-
centrations of vapor is harmful and may cause heart irregularities, uncon-
sciousness, or death. Misuse can be fatal. Vapor is heavier than air and
reduces the amount of oxygen available for breathing. Product causes eye
and skin irritation. Decomposition products are hazardous.
DO NOT USE OXYGEN to purge lines or to pressurize a chiller for any
purpose. Oxygen gas reacts violently with oil, grease, and other common
substances.
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 USE air for leak testing. Use only refrigerant or dry nitrogen.
DO NOT VALVE OFF any safety device.
BE SURE that all pressure relief devices are properly installed and func-
tioning before operating any chiller.
THERE IS A RISK OF INJURY OR DEATH by electrocution. High volt-
age may be present on the motor leads even though the motor is not run-
ning. Open the power supply disconnect before touching motor leads or
terminals.
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 pro-
duces toxic gases.
DO NOT work on high-voltage equipment unless you are a qualified elec-
trician.
DO NOT WORK ON electrical components, including control panels,
switches, VFD, or oil heater until you are sure ALL POWER IS OFF and
no residual voltage can leak from capacitors or solid-state components.
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.
DO NOT ATTEMPT TO REMOVE fittings, covers, etc., while chiller is
under pressure or while chiller is running. Be sure pressure is at 0 psig (0
kPa) before breaking any refrigerant connection.
TO AVOID an electric shock hazard, verify that the voltage on the bus
capacitors has discharged completely before servicing. Check the DC bus
voltage at the Power Terminal Block by measuring between the +DC and -
DC terminals, between the +DC terminal and the chassis, and between the
-DC terminal and the chassis. The voltage must be zero for all three mea-
surements.
THE USER is responsible to conform with all applicable local, national,
and international codes. Failure to observe this precaution could result in
damage to, or destruction of, the equipment.
THIS DRIVE contains ESD (Electrostatic Discharge) sensitive parts and
assemblies. Static control precautions are required when installing, testing,
servicing or repairing this assembly. Component damage may result if
ESD control procedures are not followed. For static control procedures,
reference Rockwell publication Guarding Against Electrostatic Damage, or
any other applicable ESD protection handbook.
DO NOT alter the setting of any jumper. Failure to observe this precaution
could result in damage to, or destruction of, the equipment.
USE OF power correction capacitors on the output of the drive can result
in erratic operation of the motor, nuisance tripping, and/or permanent dam-
age to the drive. Remove power correction capacitors before proceeding.
Failure to observe this precaution could result in damage to, or destruction
of, the equipment.
MOST CODES require that upstream branch circuit protection be pro-
vided to protect input power wiring. If fuses are chosen as the protection
method, refer to the PowerFlex 750 user manual. Failure to observe this
precaution could result in damage to, or destruction of, the equipment.
DO NOT route signal and control wiring with power wiring in the same
conduit. This can cause interference with drive operation. Failure to
observe this precaution could result in damage to, or destruction of, the
equipment.
DISTRIBUTION SYSTEM short circuit capacity shall not exceed the rat-
ing of the drive. Failure to observe this precaution could result in damage
to, or destruction of, the equipment.
DO NOT STEP on refrigerant lines. Broken lines can whip about and
release refrigerant, causing personal injury.
DO NOT climb over a chiller. Use platform, catwalk, or staging. Follow
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 VFD, TOWER FAN, OR PUMPS. Open the disconnect ahead of the
VFD, tower fans, or pumps.
USE only repair or replacement parts that meet the code requirements of
the original equipment.
PERIODICALLY INSPECT all valves, fittings, and piping for corrosion,
rust, leaks, or damage.

O 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 chiller 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 pan-
els, 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.
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.
NEVER APPLY an open flame or live steam to a refrigerant cylinder.
Dangerous over pressure can result. When it is necessary to heat
refrigerant, 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
emptied, 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 chiller. The introduction of the wrong refrigerant can cause dam-
age or malfunction to this chiller.

cited herein should comply with ANSI/ASHRAE 15 (latest edition).
Contact Carrier for further information on use of this chiller with other
refrigerants.
DO NOT ATTEMPT TO REMOVE fittings, covers, etc., while
chiller is under pressure or while chiller is running. Be sure pressure is
at 0 psig (0 kPa) before breaking any refrigerant connection.
CAREFULLY INSPECT all relief devices, rupture discs, and other
relief devices AT LEAST ONCE A YEAR. If chiller operates in a
corrosive atmosphere, inspect the devices at more frequent intervals.
DO NOT ATTEMPT TO REPAIR OR RECONDITION any relief
device when corrosion or build-up of foreign material (rust, dirt, scale,
etc.) is found within the valve body or mechanism. Replace the
device.
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 STEP on refrigerant lines. Broken lines can whip about and
release refrigerant, causing personal injury.
DO NOT climb over a chiller. 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 compo-
nents are light, use mechanical equipment when there is a risk of slip-
ping or losing your balance.

ENGAGE THE STARTER, TOWER FAN, OR PUMPS. Open the
disconnect ahead of the starter, tower fans, or pumps.
USE only repair or replacement parts that meet the code requirements
of the original equipment.
DO NOT VENT OR DRAIN waterboxes containing industrial brines,
liquid, gases, or semisolids without the permission of your process
control group.
DO NOT LOOSEN waterbox cover bolts until the waterbox has been
completely drained.
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.
