SAFETY CONSIDERATIONS
Installing, starting up, and servicing this equipment can be
hazardous due to system pressures, electrical components, and
equipment location. Only trained, qualified installers and ser-
vice technicians should install, start up, and service this equip-
ment. When working on this equipment, observe precautions in
the literature, on tags, stickers, and labels attached to the equip-
ment, and any other safety precautions that apply. Follow all
safety codes. Wear safety glasses and work gloves. Use care in
handling, rigging, and setting this equipment, and in handling
all electrical components.
WARNING
Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation and ser-
vice. There may be more than one disconnect switch. Tag
all disconnect locations to alert others not to restore power
until work is completed.
WARNING
DO NOT VENT refrigerant relief valves within a building.
Outlet from relief valves must be vented in accordance
with the latest edition of ANSI/ASHRAE (American
National Standards Institute/American Society of Heating,
Refrigerating and Air Conditioning Engineers) 15 (Safety
Code for Mechanical Refrigeration). The accumulation of
refrigerant in an enclosed space can displace oxygen and
cause asphyxiation. Provide adequate ventilation in
enclosed or low overhead areas. Inhalation of high concen-
trations of vapor is harmful and may cause heart irregulari-
ties, unconsciousness or death. Misuse can be fatal. Vapor
is heavier than air and reduces the amount of oxygen avail-
able for breathing. Product causes eye and skin irritation.
Decomposition products are hazardous.
WARNING
DO NOT attempt to unbraze factory joints when servicing
this equipment. Compressor oil is flammable and there is
no way to detect how much oil may be in any of the refrig-
erant lines. Cut lines with a tubing cutter as required when
performing service. 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 system. DO NOT re-use compressor oil.
CAUTION
This unit uses a microprocessor-based electronic control
system. Do not use jumpers or other tools to short out
components, or to bypass or otherwise depart from rec-
ommended procedures. Any short-to-ground of the con-
trol board or accompanying wiring may destroy the
electronic modules or electrical components.
CAUTION
To prevent potential damage to heat exchanger tubes,
always run fluid through heat exchanger when adding or
removing refrigerant charge. Use appropriate antifreeze
solutions in evaporator and condenser fluid loops to pre-
vent the freezing of heat exchangers or interconnecting pip-
ing when the equipment is exposed to temperatures below
32 F (0° C). Proof of flow switch is factory installed on all
models. Do NOT remove power from this chiller during
winter shut down periods without taking precaution to
remove all water from heat exchangers. Failure to properly
protect the system from freezing may constitute abuse and
may void warranty.
CAUTION
Compressors require specific rotation. Swap any two
incoming power leads to correct compressor rotation.
