2.7 INSTALLATION OF
ACCESSORIES
WARNING
E
LECTRICAL 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
For single-phase models, 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. For three-
phases models or if the accessories draw more than 2
amps, a separate power source must be used.
Some accessories require control relays. A location has
been set aside in the unit for the installation of relays:
a 24 VAC (part number 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.
3.2 USE OF MANUAL FURNACE
CONTROLS ON ADVANTAGE
FURNACE
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
the “HI” position during the winter months to ensure
adequate heating.
Also, this switch must remain in the “HI” position when
a 2-stage or outdoor thermostat is used to control the
electric elements of the second stage.
Refer to the
diagram in Section 2.5. The “ON/OFF VENT/FAN” switch
engages the blower in the continuous low speed mode.
This will filter the air and provide for better air distribution
in the building.
The 15 A circuit breaker is there to protect the motor
and the control circuit conductors. If the unit does not
function, press the circuit breaker button to see if it may
have disengaged due to a power surge. If the breaker
has to be pressed again, the unit must be checked by a
qualified service technician.
