- Form a vacuum with pump.
▪ Surely perform the pump for 60~80 m in.
▪ If the vacuum tim e is less than 60min,
coefficient of performance of the refrigerator
and air cooling would be weak.
and discharge the surplus refrigerant.
▪ For your safety, work in the fresh air.
▪ Tip of adjusting:
- Check the amount of refrigerant used
for refrigerator. (ex: 64g)
- Weigh can attached adapter on the scales.
(ex: 160g+145g=305g)
∴
Discharge the refrigerant until the scales
at 284 gram s. (305g-21g=284g)
- Check the volum e of the can label. (ex: 85g)
- Calculate the amounts of discharging.
(ex: 85g-64g=21g)
- Check the gauge scale: -76cmHg
(at the standard atm ospheric pressure)
- Measure weight of R600a can with scales
