IMPORTANT INFORMATION

SAFE REFRIGERANT HANDLING

While these items will not cover every conceivable situation, they should serve as a useful guide.

WARNING

Refrigerants are heavier than air. They can "push out"

the oxygen in your lungs or in any enclosed space.To

avoid possible difficulty in breathing or death:

• Never purge refrigerant into an enclosed room or

space. By law, all refrigerants must be reclaimed.

• If an indoor leak is suspected, thoroughly ventilate

the area before beginning work.

• Liquid refrigerant can be very cold. To avoid possible

frostbite or blindness, avoid contact with refrigerant

and wear gloves and goggles. If liquid refrigerant

does contact your skin or eyes, seek medical help

immediately.

• Always follow EPA regulations. Never burn refrig-

erant, as poisonous gas will be produced.

To avoid possible explosion:

• Never apply flame or steam to a refrigerant cylinder.

If you must heat a cylinder for faster charging,

partially immerse it in warm water.

• Never fill a cylinder more than 80% full of liquid

refrigerant.

• Never add anything other than R-22 to an R-22 cylinder

or R-410A to an R-410A cylinder. The service equipment

used must be listed or certified for the type of

refrigerant used.

• Store cylinders in a cool, dry place. Never use a

cylinder as a platform or a roller.

WARNING

To avoid possible injury, explosion or death, practice

safe handling of refrigerants.

WARNING

To avoid possible explosion, use only returnable (not

disposable) service cylinders when removing refrig-

erant from a system.

• Ensure the cylinder is free of damage which could

lead to a leak or explosion.

• Ensure the hydrostatic test date does not exceed

5 years.

• Ensure the pressure rating meets or exceeds 400

lbs.

When in doubt, do not use cylinder.

WARNING

HIGH VOLTAGE!

Disconnect ALL power before servicing. Multiple

power sources may be present. Failure to do so may

cause property damage, personal injury, or death.

WARNING

System contaminants, improper service procedure

and/or physical abuse affecting hermetic compressor

electrical terminals may cause dangerous system

venting.

In either of these instances, an electrical short between the

terminal and the compressor housing may result in the loss

of integrity between the terminal and its dielectric embed-

ment. This loss may cause the terminals to be expelled,

thereby venting the vaporous and liquid contents of the

compressor housing and system.

A venting compressor terminal normally presents no danger

to anyone, providing the terminal protective cover is properly

in place.

If, however, the terminal protective cover is not properly in

place, a venting terminal may discharge a combination of

(a) hot lubricating oil and refrigerant

(b) flammable mixture (if system is contaminated

with air)

in a stream of spray which may be dangerous to anyone in the

vicinity. Death or serious bodily injury could occur.

Under no circumstances is a hermetic compressor to be

electrically energized and/or operated without having the

terminal protective cover properly in place.

See Service Section S-17 for proper servicing.

The successful development of hermetically sealed refrigera-

tion compressors has completely sealed the compressor's

moving parts and electric motor inside a common housing,

minimizing refrigerant leaks and the hazards sometimes

associated with moving belts, pulleys or couplings.

Fundamental to the design of hermetic compressors is a

method whereby electrical current is transmitted to the

compressor motor through terminal conductors which pass

through the compressor housing wall. These terminals are

sealed in a dielectric material which insulates them from the

housing and maintains the pressure tight integrity of the

hermetic compressor. The terminals and their dielectric

embedment are strongly constructed, but are vulnerable to

careless compressor installation or maintenance proce-

dures and equally vulnerable to internal electrical short

circuits caused by excessive system contaminants.
