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.

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.

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.
