Precautions for New Refrigerant (R-410A) Si34-704
374 Precautions for New Refrigerant (R-410A)
4. Leak tester
Specifications
2 Hydrogen detecting type, etc.
2 Applicable refrigerants
R-410A, R-407C, R-404A, R-507A, R-134a, etc.
Differences
2 Previous testers detected chlorine. Since HFCs do not contain chlorine, new tester detects
hydrogen.
5. Refrigerant oil (Air compal)
Specifications
2 Contains synthetic oil, therefore it can be used for piping work of every refrigerant cycle.
2 Offers high rust resistance and stability over long period of time.
Differences
2 Can be used for R-410A and R-22 units.
6. Gauge manifold for R-410A
Specifications
2 High pressure gauge
- 0.1 to 5.3 MPa (-76 cmHg to 53 kg/cm
2
)
2 Low pressure gauge
- 0.1 to 3.8 MPa (-76 cmHg to 38 kg/cm
2
)
2 1/4"
→
5/16" (2min
→
2.5min)
2 No oil is used in pressure test of gauges.
