4. Maintenance
The only maintenance your Power
Canister requires is emptying the dust
container as required and periodically
cleaning the filter.
To clean the filter:
While the filter in your Central Vac
system should not require any
maintenance, if you notice that the filter
has "dirt cake" on the filter surface and
wish to clean it, do so by following these
easy directions:
1) Remove the dirt container by
unclasping the latches on each side of
the dirt container (or twisting the dirt
container if the unit is plastic).
2) Wrap a plastic garbage bag securely
around the base of the unit so that no
dust will escape when shaking the filter
inside the garbage bag.
3) Using the plastic bag as hand
protection from dirt particles, shake the
filter to cause any particles adhering to
the filter to fall into the bag. (Fig. 4-1)
4) Reposition the dirt container and
fasten latches (or align and twist to
secure dirt canister if unit is plastic).

If you have a
problem
If a minor problem develops, it usually
can be remedied quite easily when the
cause is found by using the check list
Below.
Problem: Cleaner Won't Run
Possible cause
Possible solution
• Hose Not firmly plugged in
• Plug in firmly
• No voltage in wall plug
• Check fuse or breaker
• Blown fuse/tripped breaker
• Replace fuse/reset breaker
• Low voltage circuit incorrectly
installed
• Short low voltage terminals at
power unit, if unit starts, there is a
problem with the low volt circuit.
• Defective wall valve
• Insert the hose into another inlet
valve. If unit turns on, the inlet
valve may be defective. Replace
inlet valve.
• Problem with low voltage circuit
• Turn on central vacuum with ON/
OFF switch located on the unit.
If the unit starts, the problem is in
the wiring to the inlet valve, the 24
Volt transformer or the relay.
Contact your local Central Vac Factory
Service Center.
Problem: Suction Low
Possible cause
Possible solution
• Dirt Canister Full or Filter dirty
• Empty Canister or Clean filter
• Obstruction in hose, piping or
cleaning tools
• Determine if the blockage is in the
hose or piping by inserting hose
in an inlet valve. Check to see if
there is any suction at another
inlet valve by opening the cover. If
there is, plug the hose into the
second wall valve and feel the
end of the hose to see if there is
regular suction.
If the blockage is in the hose, insert a
long blunt item, such as a broom
handle, to clear the blockage. If the
blockage is in the pipe, insert hose into
wall valve and place hand over end of
hose to cut off air flow. Place your hand
on and off the end of hose rapidly
several times. If this does not clear the
blockage, reverse vacuum by using a
utility shop vacuum at the blocked valve
to vacuum blockage out. If this does not
work contact your local Central Vac
Service Center. Check tools, wands,
etc. For blockages.
• System tubing and/or wall
valves incorrectly installed
• Check to make sure all inlet valves are
properly closed.
• Dirt container full or mis-positioned
• Check to see if the dirt container
needs to be emptied. Check to see if
the dirt bucket is properly positioned
and securely twisted on plastic unit, and
latches are snapped on metal unit.
