Start-Up, Operation, and Maintenance Instructions
SAFETY CONSIDERATIONS
Centrifugal liquid chillers are designed to provide safe and
reliable service when operated within design specifica-
tions. When operating this equipment, use good judgment
and safety precautions to avoid damage to equipment and
property or injury to personnel.
Be sure you understand and follow the procedures and
safety precautions contained in the chiller instructions as
well as those listed in this guide.
DO NOT VENT refrigerant relief valves within a building. Outlet
from rupture disc or relief valve must be vented outdoors in accor-
dance with the latest edition of ANSI/ASHRAE 15 (American
National Standards Institute/American Society of Heating, Refrigera-
tion, and Air Conditioning Engineers). The accumulation of refriger-
ant 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. Inhalation of
high concentrations of vapor is harmful and may cause heart irregular-
ities, unconsciousness, 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 pres-
sures 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
functioning before operating any chiller.
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 disconnect before touching motor leads or terminal
s.
D
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.
Operation of this equipment with refrigerants other than those
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.
BE AWARE that certain automatic start arrangements CAN
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.
PROVIDE A DRAIN connection in the vent line near each pressure
relief device to prevent a build-up of condensate or
rain water.
