MAINTENANCE
N.B. In order for the warranty to be valid, the unit must be cleaned regularly. Moreover, a qualified technician must examine your furnace on
a regular basis.
Cut off power supply at circuit breaker/fuse before cleaning the unit. Use a soft rag for dusting. When cleaning, use only a damp rag and non-abrasive dish soap.
Do not use abrasive or chemical cleaners because they can damage the finishing. If the unit is used in a very dusty location, use a vacuum brush to remove dust
and other foreign objects.
N.B. Note that there is electrical current to the unit even if the thermostat is off. Meaning that there is a risk of electric shock as long as the unit
is energized
.
Preventive maintenance
Do not try to repair your furnace yourself. Call a qualified technician. However, before calling a technician, check the following points:
1) Make sure fuses or circuit breakers are activated;
2) Adjust the temperature set point of the thermostat above the ambient temperature. If heating does not start, cut off the power supply and call a technician.
N.B. When calling a technician for maintenance or to order a replacement part, specify the model of your furnace as well as its serial number.
Air filter
Excessive dust or dirt accumulation can block the airflow, forcing the unit to work harder to maintain the desired temperature. Therefore, it uses more energy and
increases heating costs.
Since the air filter supplied is disposable, you should replace it two to four times a year, according to the model used and the installation area. Dirtier areas can
require more than four filter changes.
To replace a dirty filter, open the access door to the filter, remove the old filter and insert the new one inside the rack. Make sure the new filter has the same techni-
cal specifications and size as the previous one.
N.B. Never operate the unit without a filter in place.
Every time a filter is changed, you should check the following points.
- Excessive accumulation of dirt or dust on furnace components.
- Damaged components or surfaces.
- Presence of water inside or outside the furnace.
If you encounter any of these problems, do not operate the furnace. Call a qualified technician.
Blower
The blower motor is sealed and permanently lubricated, so it is not necessary to lubricate it.
Even if you change the filter frequently, the blower’s blades and motors will become dust laden after a few months. The entire blower assembly should be
inspected annually. If needed, vacuum out the dust. If you cannot clean the blower without removing it from the furnace, this service must be performed by a
qualified technician.
TROUBLESHOOTING
If you encounter a problem, check the following table before calling a technician. Should modification or servicing be required, make sure the technician uses only
factory authorized parts, accessories, or kits for this furnace.
PROBLEM
DEFECTIVE PART OR PART TO CHECK
The unit does not work
- Defective thermostat or wrong thermostat setting or location
- Open circuit breaker or fuse
The unit runs continuously
- Blower control switch is on the continuous position
Overheating
- Defective thermostat or wrong thermostat setting or location
- Defective motor
The on/off cycles of the motor are too short or too long
- The heat anticipator is incorrectly set or is burned out (if applicable)
The thermostat must be set at a much higher or lower temperature than the
desired ambient temperature
- The thermostat is not levelled, needs calibration or is installed in an improper location
The desired room temperature cannot be reached
- The thermal protections opens the circuit because of duct obstructions or dirty filters
