CAUTION
Compressor damage!
Do not use a Meg ohm meter or apply
power to the winding of a compressor
while it is under a deep vacuum. This
may damage the motor windings.
WARNING
Hazardous pressure!
If heat is required to raise the
refrigerant pressure during
refrigerant removal, use only warm
water or heat blankets. Do not exceed
150°F. Do not apply a direct flame to
the refrigerant container. Failure to
follow thee safety precautions can
result in a violent explosion, which
could result in death or serious injury.
Charging the Refrigerant System
To completely charge the system, charge
gaseous refrigerant into the suction line
shrader valve with the unit running.
However, make sure that some
refrigerant is present in each circuit
before starting the compressors.
CAUTION
Compressor damage!
Do not allow liquid refrigerant to enter
the suction line. Excessive liquid may
damage the compressor.
CAUTION
Compressor damage!
Never manually or automatically
pump down below 7 psig. This may
cause the compressor to operate in a
vacuum and cause compresor
damage.
