MOUNTING RACK
Thank you for choosing an Expressions Duct Free System. The same pride in craftsmanship and engineering knowledge that goes into equipment cooling the Astrodome in Texas, the Sistine Chapel in Rome, the U.S. Capitol Hall of Congress, and thousands of other installations worldwide has gone into the construction of this unit.
Expressions Duct Free Systems provides quiet, maximum comfort. In addition to cooling and/or heating, the Duct Free System will filter and dehumidify the air in the room to provide maximum comfort. Depending on the specific application, the unit can be installed on a wall or a under ceiling.
IMPORTANT: The Expressions Duct Free System should be installed by authorized personnel only, using approved tubing and accessories. If technical assistance, service or repair is needed, contact the installer or call 1-800-227-7437.
GENERAL
The Duct Free System can be set up and operated from the remote control (provided). See Fig. 1. If the remote is mis­placed, the system can be operated from the “Auto” set ting on the unit.
Operating Modes —
ing modes:
• Cooling
•Fan Only
• Heating (if applicable)
• Dehumidification
•Auto COOL ING — In Cooling mode, the system cools, dries and
filters room air.
The duct free system has 5 operat-
FAN ONLY — In Fan Only mode, the system filters and cir­culates room air without changing room air temperature.
HEATING — In Heating mode, the system heats and filters room air.
DEHUMIDIFICATION — In Dehumidification mode, the system dries, filters and slightly cools room air temperature. This mode
does not
take the place of a dehumidifier.
AUTO — In Auto mode, the system will automatically cool or heat room air according to a selected temperature (set point).
If temperature of room air is lower than set point, the system will operate in Heating mode. If temperature of room air is higher than set point, the system will operate in Cooling mode.
Remote Control —
The remote control transmits com­mands to set up and operate the system. T he controller has a window display panel that shows the current system status. The controller can be secured to a surface when used with the mounting rack provided. See Fig. 1.
Handle the controller with care and avoid getting the con­troller wet. Damage to the device may result.
Do not leave remote control in a drawer or near a warm/hot appliance as the system will try to cool the environment around the controller.
IMPORTANT: The remote control and unit continually exchange information regarding room air temperature. When operating the remote control from the mounting rack, be sure there is a direct line of sight bet ween the controller and the unit. The controller can operate the unit from a distance of up to 23 ft as long as there are not any obstructions.

The system can be operated from the unit in the event the remote control is not working or is misplaced.
TURN UNIT ON — Slide the Operation Switch on the unit to the AUTO position. The unit will operate at a temperature set­ting of 74 F and will automatically select the required operation mode and fan speed to maintain this setting.
TURN UNIT OFF — Slide the Operation Switch on the unit to the OFF position.
REMOTE CONTROL OPERATION — To return the sys­tem to Remote Control operation, slide the Operation Sw itch on the unit to the REMOTE position. The remote control will now operate the system. Refer to Remote Control Oper­ation section for remote control instructions.
CLEANING AND MAINTENANCE
To avoid the possibility of electric shock, a lways 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.
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.
Air Filters
Filter lamp on the unit display panel is lit. See Fig. 14 and 15. NOTE: If air filters show signs of excessive wear or ar e torn,
they must be replaced. Contact your local dealer for replace­ment filters.
1. Open front panel on unit.
2. Pull filters down to remove.
3. Vacuum filters.
4. Clean with warm water.
Remove and clean the air filters when the
5. Shake filter to remove excess water and dry thoroughly.
6. Replace filter by sliding filter behind front grille until fil­ter snaps in place. See Fig. 15.
7. Slide Operation Switch on unit to OFF position to cancel Filter status lamp.
8. Slide Operation Switch on unit to REMOTE position to resume remote control operation.
Indoor Unit Front Panel
To clean the front panel on the indoor unit, wipe the outside with a soft, dry cloth. If neces­sary, a mild liquid detergent can be applied and wiped off with a dry cloth.
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.

Outdoor Unit Coil
To clean the outdoor unit coil fol-
low the steps below:
Sharp fins and other metal parts on the outdoor unit coil can cause personal injury during cleaning.
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 de bris that may inhibit heat transfer.
Condensate Drains
Clean all condensate drains at the start of each cooling season. Check the flow by pouring wa­ter into the drain.
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 activit ies while
unit is on.
• Keep remote control out of direct sunlight and heat.
• Ke ep 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.
DIP Switch Settings
The remote control contains seven DIP switches, located in the battery compartment, two of which control special system charact eristics. See Fig. 16. The DIP switch default positions are set according to the model air conditioner installed, as per the following table.
SWITCH12 3 4 567
POSITION ON OFF OFF OFF OFF ON OFF
Switch No. 3 should be set as follows: OFF (default) — When only one air conditioner is installed
in the room.
ON — When there are two air conditioners with remote controllers installed in the room, in one of the remote control­lers this switch must be in the ON position. To activate the new switch setting, simultaneously press the MODE and ROOM buttons.
Switch No. 4 should be set as follows:
OFF — Displays temperature in °C, with a 24-hour clock format.
ON — Displays temperature in °F, with a 12-hour clock (PM indictor) format.
T o operate t he special systems cha racteri stics:
1. Remove the batteries.
2. Set the DIP switches to the required positions.
3. W ait approximately 2 minutes and return batteries to proper position.
Energy Saving Recommendations
The follow­ing 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.
• Do not obstruct front grille air intake on front panel.
• Turn on air conditioning before indoor air becomes too
uncomfortable.
