Installation Instructions
SAFETY CONSIDERATIONS
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.
DO NOTVENT 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 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 INJURYOR 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 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.
LOCK OPENAND 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, IMMEDIATELYFLUSH
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 re-
frigerant, use only warm (110 F [43 C]) water.
DO NOT REUSE disposable (nonreturnable) cylinders or attempt to
refill them. It is DANGEROUSAND 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 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 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.
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.
