SAFETY CONSIDERATIONS

Installing, starting up, and servicing air-conditioning
equipment can be hazardous due to system pressures, electrical
components, and equipment location.
Only trained, qualified installers and service mechanics
should install, start up, and service this equipment.
Untrained personnel can perform basic maintenance func-
tions such as cleaning coils. All other operations should be
performed by trained service personnel.
When working on the equipment, observe precautions in the
literature and on tags, stickers, and labels attached to the
equipment.
• Follow all safety codes.
• Keep quenching cloth and fire extinguisher nearby when
brazing.
• Wear safety glasses and work gloves.
• Use care in handling, rigging, and setting bulky
equipment.
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.
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 pursuant to
International Standard in North America EN 61000-2/3,
which are designed to provide reasonable protection
against such interference when operated in a commercial
environment.
This system uses Puron
higher pressures than R-22 and other refrigerants. No other
refrigerant can be used in this system. Failure to use gage
set, hoses, and recovery systems designed to handle Puron
refrigerant (R-410A) may result in equipment damage or
personal injury. If unsure about equipment, consult the
equipment manufacturer.
