Start-Up, Operation, and Maintenance 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
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 instruc-
tions as well as those listed in this guide.
DO NOT VENT refrigerant relief valves within a buikting. 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 hamlfill and may cause heart irregular-
ities, nnconsciousness, or death. Misuse can be fatal. Vapor is heavier
than air and rednces the amonnt 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
COlnlllOn
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
fimctioning before operating any chiller.
THERE IS A RISK OF INJURY OR DEATH by electrocution. High
voltage may be present on the motor leads even though the motor is
not running. Open the power supply disconnect before touching
motor leads or terminals.
DO NOT WELD OR FLAMECUT any refrigerant line or vessel until
all refrigerant (liquM atM V'al)or) has been removed from chiller.
Traces of vapor should be displaced with dry air or nitrogen and the
work area should be well ventilated. R@'ixemm in contact _Hth an
o!)et_flame prodHc_,s toxic gaxes.
DO NOT USE eyebolts or eyebolt holes to rig chiller sections or the
entire assembly.
DO NOT work on high-voltage equipment unless yon 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 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 liqnid 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 D3 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 introdnction of the wrong refrigerant can cause
damage 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 timber 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 sum pressure is
at 0 psig C0kPa) 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 morn 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.
Follow safe practices when using ladders.
USE MECHANICAL EQUIPMENT (crone, hoist, etc.) to lilt
or move inspection covers or other heax.y 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 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 withont the permission of your process
control group.
DO NOT LOOSEN waterbox cover bolts until the waterbox has been
completely drained.
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
corrosion, rest, 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 watec
