Service, and Troubleshooting
SAFETY CONSIDERATIONS
Installing, starting up, and servicing this equipment can be
hazardous due to system pressures, electrical components, and
equipment location (elevated structures, mechanical rooms,
etc.). Only trained, qualified installers and service mechanics
should install, start up, and service this equipment.
When working on this equipment, observe precautions in
the literature, and on tags, stickers, and labels attached to the
equipment, 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. There
may be more than one disconnect switch. Tag all discon-
nect 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 outdoors 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 concentrations of vapor is harmful and may cause
heart irregularities, unconsciousness or death. Misuse 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.
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
refrigerant 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. Damage
to equipment or personal injury may result.
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 recom-
mended procedures. Any short-to-ground of the control
board or accompanying wiring may destroy the electronic
modules or electrical components.
CAUTION
To prevent potential damage to heat exchanger, always run
fluid through heat exchanger when adding or removing
refrigerant charge. Use appropriate brine solutions in cooler
fluid loop to prevent the freezing of brazed plate heat
exchanger 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 dur-
ing winter shutdown periods without taking precaution to
remove all water from heat exchanger and optional
hydronic system. Failure to properly protect the system
from freezing may constitute abuse and may void warranty.
CAUTION
Compressors require specific rotation. Monitor control
alarms during first compressor start up for reverse rotation
protection. Damage to unit may result.
CAUTION
Refrigerant charge must be removed slowly to prevent loss
of compressor oil that could result in compressor failure.
CAUTION
Puron ® refrigerant (R-410A) systems operate at higher
pressures than standard R-22 systems. Do not use R-22 ser-
vice equipment or components on Puron refrigerant equip-
ment. If service equipment is not rated for Puron
refrigerant, equipment damage or personal injury may
result.
