INTRODUCTION
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.
GENERAL
The Duct Free System can be set up and operated from the
remote control (provided). See Fig. 1. If the remote is mis-
placed, the system can be operated from the “Auto” setting on
the unit.
Operating Modes — The duct free system has 5 operat-
ing modes:
• Cooling
• Fan Only
• Heating (if applicable)
• Dehumidification
• Auto
COOLING — In Cooling mode, the system cools, dries and
filters room air.
FAN ONLY — In Fan Only mode, the system filters and cir-
culates 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 com-
mands to set up and operate the system. The 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.
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.
Handle the controller with care and avoid getting the con-
troller 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 between 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.
