Check Valve - Ingersoll Rand CCE10 Manuel De Maintenance

EVERY 90 DAYS OR 500 HOURS MAINTENANCE
1. Check entire system for air leakage around fittings, connections, and gaskets, using soap solution
and brush.
2. Tighten nuts and cap screws as required.
3. Check and clean compressor valves as required. Replace when worn or damaged parts.
GENERAL MAINTENANCE NOTES
PRESSURE RELIEF VALVE: The pressure relief valve is an automatic pop valve. Each valve is properly
adjusted for the maximum pressure of the unit on which it is installed. If it should pop, it will be
necessary to drain all the air out of the tank in order to reseat properly, or drop pressure in line. Do
not readjust.
TANK DRAIN VALVE: Drain valve is located at bottom of tank. Open drain valve daily to drain
condensation. Do not open drain valve if tank pressure exceeds 25 psig. The automatic tank drain
equipped compressor requires draining manually once a week.
PRESSURE SWITCH: The pressure switch is automatic and will start compressor at the low pressure
and stop when the maximum pressure is reached. It is adjusted to start and stop compressor at the
proper pressure for the unit on which it is installed. Do not readjust.
COMPRESSOR VALVES (CCE10): Once per year or if compressor fails to pump air or seems slow in
filling up tank, disconnect unit from power source remove valve plate and clean thoroughly, using
compressed air. The valve plates can be reached by removing the cylinder head. The cylinder head
is held by four capscrews. After cleaning exceptional care must be taken that all parts are replaced
in exactly the same position and all joints must be tight or the compressor will not function properly.
When all valves are replaced and connections tight, close hand valve at tank outlet for final test.
COMPRESSOR VALVES (CCE20, CCE30, CVE50): Once per year or if compressor fails to pump air or
seems slow in filling up tank, disconnect unit from power source and remove valves and clean
thoroughly, using compressed air and a soft wire brush. The valve plates can be reached by
removing the cylinder head. Each cover is held by four capscrews. Take care not to damage the
"O"-Ring seal under the top of the cover. After cleaning exceptional care must be taken that all
parts are replaced in exactly the same position and all joints must be tight or the compressor will
not function properly. When all valves are replaced and connections tight, close hand valve at tank
outlet for final test.
Valves must be replaced in original position. Valve gaskets should be replaced each time
valves are serviced.
CHECK VALVE: The check valve closes when the compressor stops operating, preventing air from
flowing out of the tank through the unloader solenoid valve. After the compressor stops operating, if
air continues to escape through the unloader solenoid valve, it is an indication that the check valve is
leaking. This can be corrected by removing check valve and cleaning disc and seat. If check valve
disc is worn badly, replace same.
Before removing check valve be sure all air is drained out of tank and power is disconnected.
Failure to do so may result in injury or equipment damage.
