6. FILTRATION SYSTEM MAINTENANCE
In order to maintain optimal air quality in your home, the power unit comes supplied with a high-efficiency HYBRID filtering
system. A permanent polypropylene washable and reusable filter together with an optional 12.5L OR 22.5L disposable filter
bag.
NOTE
When replacing the disposable bag, make sure that the rubber diaphragm is correctly installed onto the intake PVC pipe.
Make sure that the bag is not cut or damaged. Make sure that the canister is secured in place prior to restarting the power
unit. It is recommended to replace the disposable bag or to empty the debris canister as well as t
o clean the
permanent filter 3 or 4 times per year. If the system is used more frequently than normal, repeat the above procedure
more often.
Your new system is now ready to be used. Here are a few simple guidelines to follow when using your Nadair Central Vacuum
System: Insert the wall end of the hose into one of the vacuum wall inlets installed throughout your home. When ready to start, press
the ON-OFF switch on the hose handle!
NOTE: In regards to the low-voltage system, all vacuum inlets are fitted with two (2) spring-loaded metal pins. When the hose wall-end
cuff's two (2) metal parts are in contact with the two (2) pins inside the inlet, the system is energized. You may now turn it on or off from
the hose handle switch (if this option was selected). The low-voltage cable is connected in parallel from every inlet. It runs all along with
the piping network and brings the power to the switch to remotely start or stop the power unit in all safety. A standard flexible hose, not
fitted with an interrupter, will start the power unit as soon as it is inserted into the valve opening.
The permanent filter must be washed every time the canister is emptied to prevent debris
from accumulating on the filter and to avoid debris from going into the motor compartment.
To keep the vacuum's warranty, the permanent filter must be changed for a new one every
two (2) years. The New filter must be Nadair filter: FP-8 ( FOR NAD-630ST-25H /
NAD-700ST-25H) OR FP-12 ( FOR NAD-750ST-35H)
The disposable bag must be installed as described here:
1- Remove the debris canister
2- Remove the dirt-filled bag
3- Install the new bag by twisting it
4- Verify and clean ( If necessary) the permanent filter.
5- Replace the debris canister and secure the latches
NOTE: The permanent filter MUST BE IN PLACE AT ALL TIMES; the filter securing strap must be tight and adjusted to
ensure there are no fly-by of debris into the motor housing.
IMPORTANT
NEVER USE this system to pick up liquids, mud, or combustible materials. To vacuum baking flour, talcum, powder, cement or gypsum dust,
will have for effect to obstruct and eventually clog the filter media; you have to clean the filter several times during and after such pick-ups.
Otherwise, the power unit performances will be affected, and the motor will overheat and may be damaged.
