(referto Figure 13)
Figure 13 : Electronic air cleaner connections
2.7.3- Dehumidify capability with standard humidistat
connection
Latent capacities for systems using this unit are better than
average systems. If increased latent capacity is an application
requirement, the field wiring terminal block provides a
connection terminal (DH) foruse of a standard humidistat. The
furnace control will detect the humidistat contact opening on
increasing humidityandreduceitsairflowtoapproximately80%
of nominal cooling modeairflow. Thisreduction will increase the
system latent capacity until the humidity falls to a level which
causesthe humidistatcontactto close its contacts.
When the contact closes again, the airflows comes back to
100% of the coolingairflow selected.
2.7.4- Useof 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
electricelementsand the heat pumpatthe sametime. Refer to
the instructions provided with the thermostat or the “Fossil Fuel”
kit for the properwiringof the furnaceand the heatpump.
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,sincethey are not designedtofunctioninthis fashion.

ADVANTAGE FURNACE
When thereis a demand forheat,the pilotlight(L-1) comeson.
Refer to the wiringdiagram (Figure16).
When the “HI/LO” switch is put into the “LO” position, it will shut
down approximatelyhalf 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 outdoorthermostatis used to control the electricelementsof
the secondstage. Refer to the diagram inSection 2.5-.
The “ON/OFF VENT/FAN” switch engages the blower in the
continuous low speed mode. This will filter the air and provide
forbetter air distributioninthe building.

Electrical shock or unit damage hazard
Failure to carefully read and follow this WARNING could
result in equipment malfunction, property damage,
personal injury and/or death.
Disconnect power to unit before removing or replacing
connectorsor servicingmotor. Wait atleastfive (5)minutes
after disconnecting power before handling.

3.4- AIRFLOW VERIFICATION
Verifytheairflow bytaking readingsofthefollowingpoints,while
the elementsare in heating mode:
a. Total amperage of allthe heating elements;
b. Voltage at the furnace;
c. Supply air temperature. The point of the readingmust not
be affected byradiantheat from the elements;
d. Return air temperature.
From these readings, one can arrive at an approximate
calculation of the average airflow. To do that, the following
formulashouldbeused:
0.82 x amps.x volts
Liter/s= -------------------------
Diff. temperature ˚C
3.1 x amps.x volts
CFM = ------------------------
Diff. temperature ˚F
3.4.1- Supply Air TemperatureRise Test
1. Operatethe unit at maximumpowerforatleast10 minutes;
2. Measurethe air temperatureinthe returnair plenum;
3. Measurethe air temperatureinthe largesttrunk coming off
the supplyairplenum,justoutsidethe range of radiantheat
from the heat exchanger. 0.3 m (12”) from the plenum of
the main take-off isusuallysufficient;
4. Calculatethe temperaturerise by subtractingthe return air
temperaturefrom thesupplyairtemperature.
If the temperature rise exceeds the temperature specified in
Table 2 by 5˚F/2.8°C, move the “AC/HP CFM ADJUST” black
wire to high (HI) position. If the excessive temperature rise
cannot be reduced by increasing fan speed, investigate for
ductworkobstructionsor dirty and improperairfilter.
CAUTION
It is important to check the airflow and to ascertainthat the
unit does not operate above the temperatures specified in
the Technical Specifications (Table 2). This is particularly
important if a cooling coil ora heatpump hasbeen installed
in the ducts.
Hi-Limit thermal protectors should never need to engage
during the normal functioning of the appliance. They are
strictlydesigned to engage during the improper functioning
of the blower or when the filter was improperly maintained.
3.4.2- High limit verification
After operating the furnace for at least 15 minutes, restrict the
return air supply by blocking the filters or the return air register
and allow the furnace to shut off on High Limit. The electric
heaters must deactivate themselves before the warm air
temperature exceeds 200˚F (93°C).
Removethe obstructionand the elementsshouldrestartafter a
fewminutes.
4-MAINTENANCE
WARNING
Electrical shock hazard.
Turn OFF power to the furnace before any disassembly or
servicing.
Failure to do so can result in death, bodily injury and/or
property damage.
Preventive maintenance is the best way to avoid unnecessary
expense and inconvenience. Have your heating system
inspected by a qualified service technician at regular intervals.
Do not attempt to repair the furnace or its controls. Call a
qualifiedservicetechnician.
Beforecallingforrepairservice,check the followingpoints:
1. Checkfusesor the circuit breakers;
2. Check if the 15 A circuit breaker on the furnace is
disengaged;
3. Checkif the 5 A fuseof the control boardis blown;
4. Set thethermostathigherthanroom temperature. If the unit
doesnot start up, cut the powerandcalla qualifiedservice
technician.
When callingforserviceor ordering a replacementpart,specify
the model and serial numberof yourappliance.
4.1- AIR FILTER
The disposable filter should be replaced twice a year. The
presence of animal hair, dust, etc. may necessitate more
frequent changes. Dirty filters have an adverse effect on the
performanceof the central heating system.
4.2- MOTOR LUBRICATION
Do not lubricate the blower motor, since it is permanently
lubricated.
