SAFETY CONSIDERATIONS

Improper installation, adjustment, alteration, service, 

maintenance, 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

 

operations. Have fire extinguisher available. Read these 
instructions 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. 
For Canada, refer to the current editions of the Canadian

 

Electrical Code CSA (Canadian 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 
injury or death. CAUTION is used to identify unsafe practices, 
which could 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 for the potential of personal 
injury. Installing, starting up, and servicing the equipment can

 

be hazardous due to system pressure, electrical components, 
and equipment location.

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.

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

 

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 can produce 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 necessary. Oil can ignite when exposed to

 

torch flame.

Failure to follow these procedures may result in personal 
injury or death.
