Drain Moisture from Pneumatics Filter Elements
Introduction At least once a week (daily if system is used during multiple shifts), remove the front panel and
follow the procedure below to drain moisture from (bleed) the filter elements.
Failure to drain moisture can result in system freeze up, which restricts air flow, and can render
the system inoperable. Although the time required to defrost the system will vary, defrosting
can take hours (see Defrosting Procedure Screen, page 3-30).
