CLEAN INDOOR UNIT BOTTOM PANEL — If the bottom panel of the unit becomes dirty or smudged, wipe the outside of the panel with a soft dry cloth. Use a mild liquid detergent and wipe off carefully with a dry cloth.

CLEAN INDOOR COIL — To clean the coil, remove indoor unit bottom panel and vacuum the coil fins, using care not to bend or damage fins.

CLEAN OUTDOOR COIL (Outdoor Unit)

!CAUTION

CUT HAZARD

Failure to follow this caution may result in personal injury.

Sheet metal parts may have sharp edges or burrs. Use care and wear appropriate protective clothing and gloves when cleaning. 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.

CLEAN CONDENSATE DRAINS — Clean all drains and drain pans at the start of each cooling season. Check the flow by pouring water into the drain.

To clean or replace drain pan:

1.Place a plastic sheet on the floor to catch any water that may spill from drain pan.

2.Remove the intake grille and distribution assembly (at- tached).

3.Remove the condensate water in the drain pan by letting water drain into a 3-gallon bucket.

!CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment damage.

Do not use a screwdriver to pry drain pan out of assembly

-it could damage the pan.

4.Remove the 4 screws holding the drain pan.

5.Carefully hold the drain pan to remove it from the assembly.

SERVICE

!WARNING
