To avoid the possibility of electric shock, always turn off
power to the system before performing any cleaning or
maintenance to the system. Turn off the outdoor disconnect
switch located near outdoor unit. Be sure to disconnect
indoor unit if on a separate switch.
Indoor Unit Front Panel — To clean the front panel on
the indoor unit, wipe the outside with a soft, dry cloth. If neces-
sary, a mild liquid detergent can be applied and wiped off with
a dry cloth.
Operating the system with dirty air filters may damage the
indoor unit and could cause reduced cooling performance.
Intermittent system operation, frost build-up on indoor coil
and blown fuses may also result from system operation
with dirty air filters.
When cleaning the front panel, do not use water hotter than
105 F and do not pour water onto the fan coil.
Do not use abrasive or petroleum based cleaners as they
may damage the front panel.
Air Filters — Remove and clean the air filters when the
Filter lamp on the unit display panel is lit. See Fig. 14 and 15.
NOTE: If air filters show signs of excessive wear or are torn,
they must be replaced. Contact your local dealer for replace-
ment filters.
1. Open front panel on unit.
2. Pull filters down to remove.
3. Vacuum filters.
Indoor Unit Coil — To clean the indoor unit coil, remove
the front panel and vacuum the coil fins. Avoid bending or
damaging the fins.

Fig. 15 — Removing Air Filters
To operate the special systems characteristics:
1. Remove the batteries.
2. Set the DIP switches to the required positions.
Outdoor Unit Coil — To clean the outdoor unit coil fol-
low the steps below:
3. Wait approximately 2 minutes and return batteries to
proper position.
Sharp fins and other metal parts on the outdoor unit coil
can cause personal injury during cleaning.
Energy Saving Recommendations — The follow-
ing recommendations will add greater efficiency to the duct
free system:
• Select a comfortable thermostat setting and leave it at
chosen setting. Avoid continually raising and lowering
the setting.
• Keep unit filter clean. Frequent cleaning may be neces-
sary depending on indoor air quality.
• Use drapes, curtains or shades to keep direct sunlight
from heating room on very hot days.
1. Remove any dirt, debris or obstruction from discharge
opening.
2. Use a garden hose to spray water on coil. Be sure to spray
between coil fins to remove any debris that may inhibit
heat transfer.
Condensate Drains — Clean all condensate drains at
the start of each cooling season. Check the flow by pouring wa-
ter into the drain.
• Do not obstruct front grille air intake on front panel.
• Turn on air conditioning before indoor air becomes too
uncomfortable.
System Operation Check List — The items outlined
in the following list will help to assure proper system operation:
• Be sure unit is connected directly to electrical supply.
• Replace both remote control batteries at the same time
when the Low Battery symbol appears.
• Point the remote control toward the unit display panel
when transmitting a command.

• Place the remote control in a location where there is a
direct line for transmission of data to the unit.
• Select a moderate temperature setting. Extreme tempera-
tures waste electricity.
• Keep doors and windows closed while unit is operating.
• Close air vents in unoccupied rooms to save electricity.
• Contact an authorized service representative if a problem
arises that cannot be easily resolved.
• Do not perform cleaning or maintenance activities while
unit is on.
• Keep remote control out of direct sunlight and heat.
• Keep display panel on unit away from direct sunlight and
heat as this may interfere with remote control transmissions.
• Do not block air intakes and outlets on the indoor or out-
door units.
