SAFETY CONSIDERATIONS
Centrifugal and screw compressor liquid chillers are designed to
provide safe and reliable service when operated within design
specifications. 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 pre-
cautions contained in the chiller instructions as well as those listed
in this guide.
DANGER
Failure to follow these procedures will result in severe personal
injury or death.
ONLY QUALIFIED electrical personnel familiar with the
construction and operation of this equipment and the hazards
involved should install, adjust, operate, or service this
equipment.
READ AND UNDERSTAND this manual and other applica-
ble manuals in their entirety before proceeding. Failure to ob-
serve this precaution could result in severe bodily injury or loss
of life.
DO NOT install modification kits with power applied to the
drive. Disconnect and lock out incoming power before at-
tempting such installation or removal. Failure to observe this
precaution could result in severe bodily injury or loss of life.
UNUSED WIRES in conduit must be grounded at both ends to
avoid a possible shock hazard caused by induced voltages.
Also, if a drive sharing a conduit is being serviced or installed,
all drives using this conduit should be disabled to eliminate the
possible shock hazard from cross-coupled motor leads. Failure
to observe these precautions could result in bodily injury.
DO NOT VENT refrigerant relief valves within a building.
Outlet from rupture disc, relief valve or any other type of safety
relief device must be vented outdoors in accordance with the
latest edition of ANSI/ASHRAE 15 (American National Stan-
dards Institute/American Society of Heating, Refrigerating,
and Air-Conditioning Engineers). The accumulation of refrig-
erant 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 spac-
es. Inhalation of high concentrations of vapor is harmful and
may cause heart irregularities, unconsciousness, or death. Mis-
use 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 al-
lowable test pressure by checking the instruction literature and
the design pressures 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.
THERE IS A RISK OF INJURY OR DEATH by electrocu-
tion. High voltage may be present on the motor leads even
though the motor is not running. Open the power supply dis-
connect before touching motor leads or terminals.
