  • Page 15: Re-Inflation From Zero Pressure

    RE-INFLATION FROM LOW SYSTEM PRESSURE If re-inlfating from low system pressure and the compressor continues to cycle without building pressure. The inline moisture collector valve could be open due to insufficient vaccum. With the compressor running, check the blue valve as shown for air leakage. To close this valve, firmly push it in for 5-10 seconds with the compressor running, this will build vaccum and shut the value allowing for the system to pressurise.
