Branch Kit 1:3 Gas Leak Test • Use a leak detector manufactured specially for the HFC refrigerant (R410A, R134a, etc.) when testing R410A. The sensitivity of leak detectors for previous HCFC refrigerants (such as R22) lowers to about 1/40 when used with HFC refrigerants and these detectors cannot be used. WIRING 1.
