2.6 SUPPLY AIR ADJUSTMENTS
The supply air must be adjusted based on heating/air
conditioning output and the static pressure of the duct
system. For the desired airflow, refer to Table 1, as well
as Table 4 and Table 5 for the airflow based on static
pressure.
For the adjustment of the airflow on heating mode, to
obtain the temperature rise described in the technical
specification table Table 2 and Table 3), the orange wire
must be positioned on the terminal corresponding to the
LOW, MED-LOW, MED-HIGH or HIGH blower speed.
For the adjustment of the airflow on air-cooling mode,
to obtain a sufficient airflow (350 to 450 CFM per
Ton), the blue wire must be positioned on the terminal
corresponding to the LOW, MED-LOW, MED-HIGH or
HIGH blower speed.
Blower speeds are adjusted in factory for 0.5 inch W.C.

If heating and air-cooling speeds are the same, the
orange wire and the blue wire can be connected on the
same terminal on the motor.
2.7 INSTALLATION OF
ACCESSORIES
WARNING
ELECTRICAL SHOCK HAZARD
Turn OFF electrical power at the fuse box
or service panel before making any electrical
connection and ensure that a proper ground
connection is made before connecting line
voltage.
Failure to do so can result in death or bodily injury.
2.7.1 Humidifier and electronic air cleaner
UNIQUE This unit is equipped with a 120 VAC terminal
for the connection of accessories up to a maximum of
2 amps. A humidifier and an electronic air cleaner can
be wired to terminals L1 and N of the unit. Refer to
the wiring diagrams in this manual (Figure 12 and Figure
13). A field supplied 24 VAC transformer can be installed
for accessories using 24 VAC. A separate power source
must be used if the accessories draw more than 2 amps.
Some accessories require control relays. A location has
been set aside in the unit for the installation of relays:
a 24 VAC (part number OFE-L01H009 ). In addition, a
24 VAC relay can be wired between terminals W1 and C
to be activated during a call for heat. Refer to the wiring
diagrams for the location of the relay RACC on the control
panel and in accessory instructions.
2.7.2 Use of a heat pump
When using a heat pump, a thermostat with dual fuel
option or a fossil fuel kit is required that prevents the
operation of the electric elements and the heat pump at
the same time. Refer to the instructions provided with the
thermostat or the “Fossil Fuel” kit for the proper wiring
of the furnace and the heat pump. The simultaneous
operation of the electric elements and the heat pump will
cause overheating of either unit. The safety controls of
the appliances will shut down the elements or heat pump,
since they are not designed to function in this fashion.
3 OPERATION
3.1 START-UP
Before starting up the unit, be sure to check that the
following items are in compliance:
1. The electrical installation and ventilation are
conform;
2. The blower access door is in place and the blower
rail locking screws are well tightened;
3. The blower speed adjustments for heating and air
conditioning are appropriate and in accordance
with to the specifications in this manual;
4. The thermostat of the room is in heating mode and
is set higher than the ambient temperature;
5. The breakers on front panel are set on the “ON”
position.
To start the unit, turn the main electrical switch on.

When there is a demand for heat, the pilot light (L-1)
comes on. Refer to the wiring diagram.
When the “HI/LO” switch is put into the “LO” position, it
will shut down approximately half the elements.
However, it is important to put the switch back to
