5-8. Refrigeration System, General Repairs

WARNING

DANGEROUS CHEMICAL (R22) is used in this equipment.

DEATH

or severe damage may result if personnel fail to observe safety precautions. Use

great care to avoid contact with liquid refrigerant or refrigerant gas being

discharged under pressure. Sudden and irreversible tissue damage can result

from freezing. Wear thermal protective gloves and a face protector or goggles in

any situation where skin-eye-contact is possible. Prevent contact of refrigerant

gas with flame or hot surfaces. Heat causes the refrigerant to break down and

form carbonyl chloride (phosgene), a highly poisonous and corrosive gas.

REFRIGERANT UNDER PRESSURE

is used in the operation of this equipment.

DEATH

or severe injury may result if you fail to observe safety precautions. Never use a

heating torch on any part that contains refrigerant - 22. Do not let liquid refrigerant

touch you, and do not inhale refrigerant gas.

NOTE

The refrigeration system must be totally discharged before any maintenance action

that requires opening of the pressurized system. Leak testing and dehydrator

replacement are required after any system component has been removed and

replaced. The system must be evacuated before it is charged. The system must

be properly charged to function properly.
