N.B.  In  order  for  the  warranty  to  be  valid,  the  unit  must  be 

cleaned regularly.

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 may damage the finishing. If the unit is used 

in a very dusty location, use a vacuum brush to remove dust and 

other foreign objects from the grilles. Note that cigarette smoke 

could yellow the discharge grille and that the best way to prevent it 

is to clean the unit on a regular basis.

Do not use cleaning products identified with these symbols: 

N.B. Note that there is electrical current linked to the unit 

even if the thermostat is set off. This means 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 technical 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.
