Step 6: Mount fresh air intake manifold. Connect to air source and compressor intake mufflers. Note: Mount no more than 3’ above compressor suction intake(s).
Equipment Alert Tight bends will cause hose to collapse and lead to compressor failure. To prevent moisture from entering the compressor, remote fresh air intake air temperature must not exceed compressor room air temperature by more than 20°. If necessary, route the intake to a source inside the building away from the compressor room.

Step 13: Check gauge reading after 10 minutes. Note: If the storage pressure gauge registers a lower reading, an air leak exists. Locate the leak(s) and repair.
Equipment Alert Verify all leaks are sealed. Air leaks are the main cause of compressor failures!
Caution Always disconnect the power before servicing. The head(s) surface(s) can be very hot depending on pump usage. Do not touch these parts during or directly after operation.
