MAINTENANCE

Filters must be replaced with filters of the same size, type, and efficiency rating in order to
maintain the performance of the unit. Incorrect filters can lead to premature motor failure and will
void the manufacturer's warranty. Check with the distributor or manufacturer to determine the
exact filter configuration for the specific installation.
Remove the filter cabinet door by unlatching the top and bottom latches and removing the door.
Remove the dirty filters by sliding them out of the open door side. Place the new filters in the
same location, observing the air flow direction.
Adsorbent Filter Tray
The unit is shipped with the adsorbent filters wrapped in a protective film. The protective film must
be removed prior to operation. Remove the filter cabinet door and slide out the adsorbent filter
tray. Remove the screws that hold the end panel in place and remove the end panel. Slide the
individual adsorbent filters from the tray, remove the protective wrap and place the filters back into
the adsorbent filter tray. Replace the end panel and the screws. Repeat the process for the
remaining filters.

Do not operate the unit without the filters in place or with an access
door open as this will place a load on the motor that exceeds its
rating and will damage the motor.
Replace filters only with factory supplied or factory approved filters
to ensure continued performance and continuance of factory
warranty.
Do not operate the unit without a discharge duct or a shield to
protect personnel from the high velocity air discharge. Dirt and other
material can be propelled with sufficient force to cause injury.
