SAFETY CONSIDERATIONS
Centrifugal liquid chillers are designed to provide safe and reli-
able service when operated within design specifications. When
operating this equipment, use good judgment and safety pre-
cautions 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 instructions, 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, relief valve, purge unit, or
fusible plugs must be vented outdoors in accordance with
the latest edition of ANSI/ASHRAE 15 (American Nation-
al Standards Institute/American Society of Heating, Refrig-
erating and Air-Conditioning Engineers) (Safety Code for
Mechanical Refrigeration). The accumulation of refrigerant
in an enclosed space can displace oxygen and cause as-
phyxiation.
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 al-
lowable 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 in-
stalled 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. Open the power supply disconnect before
touching motor leads or terminals and wait for capacitors to
fully discharge.
