TECHNICAL OVERVIEW

ENGLISH
SLIM DUCT OVERVIEW
The indoor unit features a multi speed blower motor that
will change speed to match the capacity demand from the
outdoor unit. The motor is a dual shaft type that powers two
individual blower assemblies.
Separate motors located in the accessory supply air louver
control the operation of the motorized louvers. All of the
louver motors are controlled via commands received from the
remote control. The blower motor is controlled by both the
remote control and by commands from the outdoor unit ECU.
Refer to the Remote Control Information in the Reference
section for louver control/remote procedures.
Unlike typical air handlers found in the US market, these
units have metering devices located in the outdoor unit. The
metering devices are EEV type that are controlled by the
outdoor unit ECU.
Slim Duct Components
Power to operate the indoor unit comes from the electrical
line voltage terminal block at the outdoor unit. The wiring
includes 4 wires, 1, 2, 3 and ground. Wires 1 and 3 complete
the data path. These wires should always be 14 gauge
AWG Stranded type wire. Splices in wires 1 or 3 may cause
communication errors.
Layout of Components
The layout of the system is very straightforward and
components are easily accessed should service be required.
•
The circuit board is located under the electrical
control box cover.
•
The blower motor and blower assemblies and room
air temperature sensor are accessed at the rear of
the unit.
•
The evaporator coil and piping temperature sensor
are located under the top cover.
•
The condensate pump and float switch are accessed
under the removable panel next to the electrical
control box.
Drain Ports
The indoor unit has
the option for either
gravity drain systems
or the use of an
internal condensate
pump with float
switch. The pump is
capable of minimal
lift. If high lift is
required, the water
from the Slim Duct unit should be pumped to a field supplied
condensate pump that is capable of high lift.
Temperature sensors located within the slim duct unit include
a pipe temperature sensor and a return air temperature
sensor. The pipe temperature sensor is used to sense the
temperature of the indoor coil in both cooling and heating
modes. The return air sensor sense the temperature of
the air being drawn into the wall mounted unit from the
conditioned space.
The wired controller can be configured to sense room air
temperature. The operating functions of these sensors is
explained in the Temperature Sensor Function section of this
manual.
All operating status and information is displayed on the wired
controller. The Slim Duct unit does not have a display.
There is no option for use with remote control.
When servicing a diagnostic error, ALWAYS refer to the
outdoor unit code to make diagnostic decisions.
