WARNING
Make sure that the unit circuit breaker(s)
(CB-1 & CB-2) and the START-STOP switch
(ST) are in the "O" (OFF) position before
connecting to any electrical power source.
WARNING
Never use air or gases containing oxygen
for leak testing or operating refrigerant
compressors. Pressurized mixtures of air
or gases containing oxygen can lead to ex-
plosion.
WARNING
Make sure power to the unit is OFF and
power plug disconnected before replacing
the compressor.
WARNING
Before disassembly of any external com-
pressor component make sure to relieve
possible internal pressure by loosening the
bolts and tapping the component with a
soft hammer to break the seal.
WARNING
Do not use a nitrogen cylinder without a
