Trane SCXG-SVX01B-EN manual Maintenance, maintenance procedures, Notice, Compressor Damage

Maintenance

To charge the system, complete the following procedure:

1.Charge liquid refrigerant into the liquid line service valve of each compressor circuit.The vacuum will draw some of the required refrigerant into the system. See Figure O-M-9.

2.Complete the charging process by charging 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. The refrigerant container should be upright so that gaseous refrigerant is drawn off the top.

Note: SeeTables M-MP-6 and M-MP-7 for refrigerant charge requirements.

NOTICE

Compressor Damage!

Do not allow liquid refrigerant to enter the suction line. Excessive liquid accumu- lation in the liquid lines may result in compressor damage.
