10.0 GENERAL MAINTENANCE

General maintenance must be performed in regular intervals to provide continued operation of
the entire unit. The maintenance intervals must be determined site specifically. Use the
maintenance checklist at the end of this manual when performing maintenance. Typically, air
filters should be replaced no less than two times per year.
FILTERS
1. The filters should be checked and changed periodically. When they become dirty, an
alarm is activated the filter pressure switch. If the filters are dirty, they must be
changed for efficient operation of your system. To check the alarm indicator, cover
approximately 75% of the return air opening; the alarm should energize. If the
alarm energizes prematurely or does not energize when it should, adjust the filter
switch. All doors to machine should remain closed before determining whether an
adjustment is necessary.
2. Spare filters should be kept in stock. Filters should be checked monthly and
replaced if necessary.
