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