Precautions for New Refrigerant (R-410A) Si34-704
376 Precautions for New Refrigerant (R-410A)
9. Weigher for refrigerant charge
Specifications
2 High accuracy
TA101A (for 10-kg cylinder) = ± 2g
TA101B (for 20-kg cylinder) = ± 5g
2 Equipped with pressure-resistant sight glass to check liquid refrigerant charging.
2 A manifold with separate ports for HFCs and previous refrigerants is equipped as standard
accessories.
Differences
2 Measurement is based on weight to prevent change of mixing ratio during charging.
10.Charge mouthpiece
Specifications
2 For R-410A, 1/4"
→
5/16" (2min
→
2.5min)
2 Material is changed from CR to H-NBR.
Differences
2 Change of thread specification on hose connection side (For the R-410A use)
2 Change of sealer material for the HFCs use.
