9-2-6. Refrigerant Charging

Required equipment:Bombe,R600a refrigerant (75g)

• First remove re appliances and heating source for performing work when charging scaled refrigerant.(Do not spray

refrigerant indoor.)

• Measure the accurate quantity (75g)of refrigerant to charge it into a Bombe.

• Make the Bomber as vacuum status to charge refrigerant. (If there is air or moisture in a Bombe,it may give effect on

performance of a cooling cycle.)

• Please manage refrigerant quantity as 75g11.Different from R134a,R600a gives much effect on cooling performance

depending on change of refrigerant quantity.

♦ GR-1137GPNM Model uses refrigerant 42g

♦ GR-3137GPNM Model uses refrigerant 44g

Refrigerant quantity =Weight after charging -Weight before charging (weight of vacuumed Bombe)

• Connect Bombe with a charging tube to charge refrigerant.

• Turn on power of refrigerator to operate a compressor.

• Measure Bombe weight after 5 through 10 minutes to check remained refrigerant quantity to complete charging of refrigerant.

(After charging refrigerant,never perform welding work or work using re appliances.)

9-2-7. Leak Inspection and Cycle Check

Required equipment:Leakage checking machine (foam and leakage inspection machine)

• Check f

or leakage by using form or a leakage inspection machine at the worked part if charging of refrigerant is completed.

• Check for leakage at the low pressure part with the compressor stopped,and check at the high pressure part with the

compressor being operating.

• If leakage is detected,proceed to repair according to repair process again starting from“2-1. Return of Refrigerator Refrigerant

”.(Never perform welding work or work using re appliances.)

• Check that h

eat remains at a discharge pipe or condenser with the hands if leakage check is completed.If heat

remains,the

cooling cycle is normal.(Take care since a discharge pipe may be hot.)
