B. To Clean or Replace Filters

Filters should be vacuumed and washed with warm water
(see Fig. 23). Shake filter to remove any excess water, dry
thoroughly, and replace by sliding filter behind front grille
until filter snaps in place.

If the filter has begun to break down or is torn, it needs to be
replaced. Replacement filters are available through your
distributor.

V. TO CLEAN INDOOR UNIT FRONT PANEL

If the front panel of the unit becomes dirty or smudged, wipe
the outside of the front panel with a soft dry cloth. If neces-
sary, use a mild liquid detergent and wipe off carefully with
a dry cloth.

CAUTION:

When cleaning the front panel, NEVER

use water hotter than 105 F, and DO NOT pour water
onto the fan coil unit. Do not use abrasive or petroleum-
based cleaners — damage to unit appearance will
result.

VI. TO CLEAN INDOOR COIL

To clean the coil, remove indoor unit front panel, and vacuum
the coil fins. Use care not to bend or damage fins.

VII. TO CLEAN OUTDOOR COIL (Outdoor Unit)

WARNING:

Some metal parts and sharp fins of out-

door unit coil can cause personal injury during clean-
ing. Clean coil carefully.

To clean the outdoor coil:

1. Remove any dirt or obstruction from discharge opening.

2. Use a garden hose to spray water on the coil. Debris that

collects between coil fins inhibits heat transfer — direct
the water spray between coil fins to flush out debris.
