must be by AUTHORIZED PERSONNEL ONLY.
SERVICE
WARNING
Death or serious injury 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.
CAUTION
•
Do not permit the oil to escape from the unit. If oil is escaping, close the valve(s)
slightly to prevent possible oil loss.
•
Do not permit the refrigerant to escape fast enough to form ice or frost on either the
lines or the valve(s) to prevent possible damage to system.
