SAFETY CONSIDERATIONS
Installing, starting up, and servicing this equipment can be
hazardous due to system pressures, electrical components, and
equipment location (roof, elevated structures, 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.

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.
This unit uses a microprocessor-based electronic control
system. Do not use jumpers or other tools to short out com-
ponents, 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.
To prevent potential damage to heat exchanger tubes
always run fluid through heat exchangers when adding or
removing refrigerant charge. Use appropriate brine solu-
tions in cooler and condenser fluid loops to prevent the
freezing of heat exchangers when the equipment is exposed
to temperatures below 32 F (0 C).
DO NOT VENT refrigerant relief valves within a building.
Outlet from relief valves must be vented outdoors in accor-
dance with the latest edition of ANSI/ASHRAE (American
National Standards Institute/American Society of Heating,
Refrigeration 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.
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.
Failure to follow these procedures may result in personal
injury or death.
DO NOT re-use compressor oil or any oil that has been
exposed to the atmosphere. Dispose of oil per local codes
and regulations. DO NOT leave refrigerant system open to
air any longer than the actual time required to service the
equipment. Seal circuits being serviced and charge with
dry nitrogen to prevent oil contamination when timely
repairs cannot be completed. Failure to follow these proce-
dures may result in damage to equipment.
