M11 Industrial Operation and Maintenance – 012-021   Air Tanks and Reservoirs

If automatic purging or spitter valves are used, confirm the valves are operating correctly. If a manual drain valve is used on the wet tank, open the draincock on the wet tank to drain any moisture accumulated in the air system. If oil is present, the air compressor system must be checked.
