ORIGINAL INSTRUCTIONS
9. TROUBLESHOOTING
Failure of the power unit could be caused by:
• Inadequate power level (voltage / amperage) (ensure that power level complies with the power unit’s electrical requirements);
• Malfunction of the motor or control module.
Simple checks can often help you fi nd out why your power unit is inoperative. We invite you to verify the following before calling a service technician.
S
ITUATION
V
ERIFICATION
NO POWER
Check that the power unit’s electrical cord is plugged directly into a power outlet;
The power unit is equipped with a mini breaker (button on the side of the motor housing) which protects the motor against an overload. To reset the mini breaker, simply
push the button. If the power goes off one more time, call a service centre near you;
Using a screwdriver fi tted with a rubber handle, touch both pins of the low voltage terminals (short circuit the 2 pins) on the side of the motor housing. If the power unit
starts, the problem lies with the low voltage wiring (installed along the piping).
You should then verify if the 24 Volts circuit is adequately connected by checking each inlet. Open the inlet cover, touch the small contacts with the head of a pair of metal
pliers with rubber handles. This will establish power and start the motor. Repeat for each vacuum inlet;
NOTE
»
If all vacuum inlets are functional and your fl exible hose is a low-voltage technology handle, then there may be a defect in the hose
cut-off switch or in the hose itself;
Check the breaker on your electric circuit panel;
DECREASED
SUCTION
The fl exible hose may be blocked. If you cannot unblock it, try inserting the opposite end of the hose into the wall inlet; touch the contacts which are located on the inside
of the inlet with the hose wand in order to start the power unit;
NOTE
»
Frame the inlet with your hands or a large enough piece of cloth (such as a towel) to ensure the maximum suction to unblock the
hose;
Check whether the dust canister / disposable fi ltration bag / permanent fi lter needs to be emptied / cleaned;
Check that the canister is clipped properly to the motor housing and that the gasket, which fi ts around it, is in good condition;
Make sure all inlets are airtight.
If the pipes are visible in certain areas: check if the fi ttings are well glued and that there are no air leaks;
If the pipes should be blocked behind the walls, it is possible to determine where the blockage is located by starting from the furthest inlet from the central vacuum. Insert
a tissue paper and check to see if the tissue paper reaches the dust canister. Repeat the same for each inlet.
