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)

Some metal parts and sharp fins of outdoor unit coil can cause personal injury during 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.

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 (attached).

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

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

When servicing unit, turn off all electric power to unit to avoid shock hazard or injury from rotating parts.

Do not vent refrigerant to atmosphere when servicing unit. Recover refrigerant during system repair or unit removal.

Before Calling for Service — Save the cost of a service

call by doing the following:

1.Be sure main power to system is turned on.

2.Press Mode button until OFF is displayed. Wait 5 min- utes.

3.Press Mode button until either COOL or HEAT is dis- played (as desired).

4.Adjust thermostat set point to desired room tempera- ture. If system starts within a few minutes, service may not be necessary. If system does not operate properly, check Table 7 for typical solutions.

IF SYSTEM FAILS TO OPERATE — Be sure:

unit ON/OFF switch is in ON position

fuse or circuit breaker is not tripped

FRESH AIR INSTALLATION OPTION

The units have an installation option, which allows for field installation of fresh air ventilation. Plan the installation careful- ly. Before beginning, measure carefully and follow acceptable building practices, NEC, and local codes.

Ventilation-Air Accessory — Refer to ventilation air accessory installation instructions.

TROUBLESHOOTING

If the under-ceiling fan coil unit fails to start or operate properly, sometimes the problem is minor and can be handled without a service call. Refer to Table 7 for some common prob- lems, causes, and typical solutions. See Fig. 20 and 21 for addi- tional system troubleshooting details. If the problem cannot be corrected, contact a local dealer for further assistance.
