Maintenance
Filters - continued
There are a number of filters available
for use with the Trane Classroom Unit
Ventilators. The following section
explains maintenance and replacement
of these filters.
Each filter is replaced in the manner
previously discussed.
Throwaway Filters
Throwaway filters contain adhesive
coated glass fibers which are enclosed
in a cardboard frame. Remove old
filters from the unit and dispose of the
entire filter. Replace with a new filter
making sure the air flow direction
arrows are pointing toward the dis-
charge end of the unit.
Permanent/Renewable
Polyurethane Filters
Permanent/renewable filters consist of
a polyurethane filter pad enclosed in a
rigid frame. The frame is hinged at the
back with dimple fastener at the front.
With the filter removed, open the
frame, remove the pad and wash in a
mild detergent solution. Allow the pad
to dry and replace in the frame.
Reinstall the filter. Over time, the filter
may wear out. Replacement pads may
be ordered through Trane.

able for periodic cleaning or easy
access for maintenance/drainage
