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.
→
For prevention of contamination
