3
Pull out and remove the front cover (see Figure 4.3 on page 4-3).
4

Remove the old filter, clean the area, then seat the new HEPA filter.

Position the front cover, tighten the screws just inside the Drier door, then push
in the upper door seal.
NOTE
#
Use caution when handling the HEPA filter to avoid damaging it. Upon receipt of new
HEPA filters, inspect both sides for holes, tears, or rips—these conditions eliminate the
effectiveness of HEPA filters.
WARNING
Electrical shock hazard when the enclosure is open. Unplug the power cord from the
electrical outlet before cleaning this device.
NOTE
#
In Model 44, the left and right plenum assemblies are mirror images of one another. For
example, the thermal cut-out on the right plenum assembly is located on the back, while
that on the left is visible from the front.
CAUTION
Avoid damaging the HEPA filter. Holes, tears, and rips adversely affect filter function.
NOTE
#
The air flow indicator on the HEPA filter must point down.
