SAFETY CONSIDERATIONS
Installing, starting up, and servicing this equipment can be hazard-
ous due to system pressures, electrical components, and equip-
ment location. Only trained, qualified installers and service me-
chanics should install, start up, and service this equipment.
When working on the equipment, observe precautions in the liter-
ature, and on tags, stickers, and labels attached to the equipment.
Follow all safety codes.
Wear safety glasses and work gloves.
Use care in handling, rigging, and setting bulky equipment.
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 disconnect locations
to alert others not to restore power until work is completed.
IMPORTANT: This equipment generates, uses, and can
radiate radio frequency energy and if not installed and
used in accordance with these instructions may cause
radio interference. It has been tested and found to comply
with the limits of a Class A computing device as defined
by FCC (Federal Communications Commission, U.S.A.)
regulations, Subpart J of Part 15, which are designed to
provide reasonable protection against such interference
when operated in a commercial environment.
WARNING
DO NOT USE TORCH to remove any component. System
contains oil and refrigerant under pressure.
To remove a component, wear protective gloves and goggles
and proceed as follows:
a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure from system
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. Refrigerant 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 neces-
sary. Oil can ignite when exposed to torch flame.
Failure to follow these procedures may result in personal inju-
ry or death.
