ESIE12-06 Precautions for New Refrigerant (R-410A)
Appendix 265
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" (2 min  2.5 min)
• No oil is used in pressure test of gauges.
