General Information
If the vacuum unit does not work, check the fuse or breaker on the unit and/ or in the electrical panel in your home, and replace any defective part(s) as deemed necessary. Please verify that the unit has been installed properly, according to the instructions in this manual.
Your vacuum cleaning system is designed to collect everyday dry matter
(dust). It is approved by authorized testing agencies for dry use only. Do not use on wet surfaces.
Should you accidentally vacuum liquids, immediately unplug the unit from the electric outlet, then empty and wipe the dust recipient with a dry cloth. Then operate the system from the vacuum inlet through which you vacuumed the liquid, in order to eliminate all moisture in the piping system.
We strongly recommend against vacuuming abrasive materials such as cement, plaster and gyproc dust. This fi ne dust could work its way into the motor, causing considerable damage. Should you do so inadvertently, immediately clean the fi lters and, as a precautionary measure, contact your authorized service center to determine the extent of the damage to the unit.
Remember that in order for your warranty to remain valid, maintenance of the motor and repairs to the unit itself must be carried out by an authorized service center, using original Cyclo Vac or Trovac parts.

Decrease in suction strength
P OSSIBLE CAUSE C ORRECTIVE ACTION
Dirt recipient / Bag is full Empty dirt recipient / change bag (see page
25).
Dirt recipient is not properly attached
Check clamps holding dirt recipient, to make sure they are tight, and dirt recipient is aligned.
Filters need cleaning / replacing
Motor guard screen is blocked
Remove, shake and/or wash fi lters or replace them (depending on model) before reinstalling them in the unit (see page 26).
Remove fi lters, and check the guard screen
(which separates the motor from the fi ltration compartment) for blockage. Ensure fi lters are always properly installed, to prevent this problem from happening again.
Open vacuum inlet Close all vacuum inlets not in use.
Exhaust line is clogged Verify that no object is blocking the exhaust.

Decrease in suction strength (cont.)
P OSSIBLE CAUSE
Blocked hose
C ORRECTIVE ACTION
Plug the handle end of the hose into the suction inlet, thus reversing the suction in the hose.
Cover the gap around the handle, to ensure suitable suction strength, and ensure contact with inlet contacts to start the unit. This should clear the hose.
Obstruction in the piping system
Remove the screw from the air intake connector, to free the central vacuum unit from the piping system (see fi gure
3 on page 8). Start the unit by plugging the hose into a vacuum inlet. By placing your extended hand over the air intake opening on the unit, check the suction strength on the unit itself.
If suction strength is normal, the obstruction is in the piping system.
If suction strength is diminished or completely absent, have the unit checked by an authorized service center.
If none of these suggestions restore suction strength, contact your authorized service center.

Vacuum will not start
P OSSIBLE CAUSE
The electrical power is not connected properly
Low voltage wire not connected properly
C ORRECTIVE ACTION
Ensure that the power cord is plugged into a dedicated grounded electrical outlet, according to specifi cations on pages
13 and 14.
Verify the low voltage wires, make sure they are properly inserted into the low voltage inlet, as per instructions on page 15.
Faulty vacuum inlet
Start the vacuum unit from other inlets in your home, to identify the defective inlet.
Unit circuit breaker is off
Press the reset button to reset the unit circuit breaker. If unit restarts and automatically shuts off shortly after, contact an authorized service center.
In-house circuit breaker is off
Reset the circuit breaker in your electrical panel.
Verify that your central vacuum unit is connected on a dedicated grounded circuit (see pages 13 and 14).
Defective on/off hose the vacuum inlet. If unit starts, have the vacuum hose checked by a certifi ed service center.

Vacuum will not stop
P OSSIBLE CAUSE C ORRECTIVE ACTION
Hose improperly inserted into vacuum inlet
Ensure that the hose end is properly placed in the vacuum inlet: the tab on the hose should fi t into the slots on the inlet, to ensure adequate contacts for the hose switch to function (see page 18).
Defective on/off hose
Low voltage wire not connected properly
If the hose is properly placed in the vacuum inlet, and the unit continues running despite the fact that the hose switch is in the “off” position, have the hose checked by a service center.
While vacuum is on, unplug low voltage wires from unit. If vacuum stops, there’s a faulty low voltage wire.
Contact your installer or authorized service center.
