SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service, main-
tenance, or use can cause explosion, fire, electrical shock, or
other conditions which may cause death, personal injury or
property damage. The qualified installer or agency must use
factory-authorized kits or accessories when modifying this
product.
Follow all safety codes. Wear safety glasses, protective
clothing, and work gloves. Use quenching cloth for brazing op-
erations. Have fire extinguisher available. Read these instruc-
tions thoroughly and follow all warnings or cautions included
in literature and attached to the unit. Consult local building
codes and the current editions of the National Electrical Code
(NEC) ANSI/NFPA (American National Standards Institute/
National Fire Protection Association) 70. In Canada, refer to
the current editions of the Canadian Electrical Code CSA (Ca-
nadian Standards Association) C22.1.
Understand the signal words - DANGER, WARNING,
and CAUTION. DANGER identifies the most serious hazards

which will result in severe personal injury or death.
WARNING signifies hazards that could result in personal inju-
ry or death. CAUTION is used to identify unsafe practices,
which would result in minor personal injury or product and
property damage.
Recognize safety information. This is the safety-alert
symbol (
). When this symbol is displayed on the unit and in
instructions or manuals, be alert to the potential for personal
injury.
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
When installing the equipment in a small space, provide
adequate measures to avoid refrigerant concentration
exceeding safety limits due to refrigerant leak. In case of
refrigerant leak during installation, ventilate the space
immediately. Failure to follow this procedure may lead to
personal injury.
WARNING
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.
