Maintenance procedures

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.
