SAFETY CONSIDERATIONS

Centrifugal liquid chillers are designed to provide safe
and reliable service when operated within design specifi-
cations. When operating this equipment, use good judg-
ment 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 machine instruc-
tions, as well as those listed in this guide.
DANGER
Failure to follow these procedures will result in severe per-
sonal injury or death.
DO NOT VENT refrigerant relief devices within a build-
ing. 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, Refrigerating and Air-Con-
ditioning Engineers) (Safety Code for Mechanical Refrig-
eration). The accumulation 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. Inhalation of high concentrations of vapor is harm-
ful and may cause heart irregularities, unconsciousness, or
death. Intentional misuse can be fatal. Vapor is heavier than
air and reduces the amount of oxygen available for breath-
ing. Product causes eye and skin irritation. Decomposition
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 litera-
ture 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 functioning 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 disconnect before
touching motor leads or terminals.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

WARNING
Failure to follow these procedures may result in personal
injury or death.
DO NOT USE TORCH to remove any component. System
contains oil and refrigerant under pressure.
To remove a component, wear protective gloves and gog-
gles and proceed as follows:
a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure from sys-
tem using both high-pressure and low pressure ports.
c. Traces of vapor should be displaced with nitrogen
and the work area should be well ventilated. Refrig-
erant in contact with an open flame produces toxic
gases.
d. Cut component connection tubing with tubing cutter
and remove component from unit. Use a pan to catch
any oil that may come out of the lines and as a gage
for how much oil to add to the system.
e. Carefully unsweat remaining tubing stubs when nec-
essary. Oil can ignite when exposed to torch flame.
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 OPEN AND TAG electrical circuits during servic-
ing. IF WORK IS INTERRUPTED, confirm that all cir-
cuits are de-energized 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 refriger-
ant 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 ILLE-
GAL. 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 machine. The introduction of the wrong
refrigerant can cause machine damage or malfunction.
