Removal of dust and other particulates from air intake areas and the
condenser is important for proper operation. Environments with large
amounts of dust may require more frequent cleaning.

front facade panel) and removing power cord from receptacle.
2. The condenser can be accessed from top for cleaning. The side panel
in front of condenser may be completely removed for easier cleaning
by disconnecting facade and removing upper side panel. See “Facade
removal” on page 30 for facade removal instructions.
3. Inspect condensate pan for any debris or obstruction in condensate
pan (Fig. 54.1).

compressor and related parts.

open arm and keeper on lower hinge assembly of door (Fig. 56.1).
