Precautions for New Refrigerant (R-410A) ESIE09-08A
286 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.
