CAUTION
Be sure air pressure is shut off before attempting maintenance work on
the air system. Make sure the bowl is properly in place and latched before
turning on air pressure.
If it becomes necessary to replace an air filter or a filter element, obtain one from
the factory. To replace the filter:
1. Turn off air to machine at supply. Make sure air pressure has gone to zero.
2. Using the release latch, remove steel bowl guard shield from filter.
3. Remove plastic filter bowl.
4. Unscrew filter element.
5. Assemble the new filter element and replace bowl and shield.
• The coalescing filter element may be washed in safety solvent and then dried
and reused once or twice and then replaced. Air filters should be washed or
replaced at intervals of 6 months if the air line is dirty.
• The coalescing filter has an O-ring on its upper surface. Be sure the O-ring is
seated properly in the groove before reinstalling.
• If the filter gets dirty fairly quickly, place another air filter/regulator upstream
of the machine.
• If excessive water is present within the air system at your facility use a Refrig-
erated Air Dryer
