The compressor contains hot, pressurized refrigerant.
Motor terminals act as a seal against this refrigerant.
Care should be taken when servicing NOT to damage or
loosen motor terminals.
Do not operate compressor without terminal box cover
in place.
Failure to follow all electrical safety precautions could
result in death or seriously injure.
CAUTION! To avoid corrosion, overheating or general
