This task covers:
Refrigeration Unit Service Tool Kit
Use disconnect switch (NOT POWER
CABLE) to disconnect power to unit.
Damage to cable connector pins will
result if cable is used.
Disconnect power at power source.
Refrigerant Recovery and Recycle Unit
Dangerous chemical refrigerant under pressure is used in the operation of this
equipment. Use great care to avoid contact with liquid refrigerant.
Sudden and irreversible tissue damage can result from freezing. Wear gloves
and a face protector or safety glasses in any situation where skin or eye contact
with refrigerant is possible.
Heat causes the refrigerant to break down and form carbonyl chloride
(phosgene), a highly toxic and corrosive gas. Prevent contact of refrigerant with
flame or hot surfaces.
Refrigerant can cause suffocation. Work in a well ventilated area.
Venting chlorofluorocarbon refrigerants into the atmosphere rather than
recovering them is a violation of public law and subject to severe penalties.
(1) Connect the charge hose to an approved container or refrigerant recovery unit.
(2) Open pressure gauge and compound gauge valves.
