Cleaning Air Filter

Air filters remove foreign matter and condensate from supply air as it passes through filter. The frequency at which the filter baffle plate and filter element should be cleaned depends upon the amount of condensate and foreign matter in the supply air. The condensate level should not raise above the baffle. That is a sign of a faulty auto-drain which would need to be cleaned, replaced or repaired.

Erratic regulator operations or loss of regulation is almost always due to dirt.

The following steps outline the procedure for cleaning the air filter.

WARNING

To avoid possible serious injury ALWAYS close air supply line shut-off valve AND lock out air service BEFORE:

•opening filter drain cock

•removing filter bowl

•filling oil bowl

Cleaning Steam Strainer

Strainer removes foreign matter from steam. The frequency at which the strainer must be cleaned is dependent upon the amount of foreign matter suspended in the steam. It is recommended that the strainer screen be removed and checked for cleanliness after 2 weeks or 80 hours of operation. If little or no foreign matter has collected on the screen, time between inspections can be increased accordingly.

WARNING

To avoid possible serious injury when cleaning or repairing traps or strainers:

•Shut off AND lock out ALL steam service to press.

•Let heated surfaces cool.
