now ready for your use.

4. Maintenance

Disconnect cord from electrical outlet
before cleaning filter.
The only maintenance your Power
Canister requires is emptying the dust
container as required and periodically
cleaning the filter.
To clean the filter:
1) Remove the dirt container by unlatch-
ing the latches located on each side of
the dirt container.
2) Place a plastic grocery bag over the
dacron/cloth filter and around the
cyclonic deflector that surrounds the fil-
ter.
3) Using the plastic bag as hand pro-
tection from dirt particles, shake the
filter to cause any particles adhering to
the filter to fall into the bag. (Fig. 4-1)
4) Replace the dirt container and
secure latches.

5) If the cloth filter should need to be
removed, grasp it near the top and pull
towards the middle of the unit in order to
remove.

6) To replace the cloth filter, you must
decrease the circumference of the filter
by pulling one side of the filter towards
the center of the filter to create a "V" or
"U" shape (see Fig. 4-2).
7) Place the filter back into the unit and
let the filter snap outward into the
groove. NOTE: Printing must be on the
inside of the bag when installed.
IMPORTANT
Make sure the cloth filter is fitting
properly into the groove so it will not
come out when the machine is turned
on. Failure to do so could void your
warranty.
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
• Not firmly plugged in
• Plug in firmly
• No voltage in wall plug
• Check fuse or breaker
• Blown fuse/tripped breaker
• Replace fuse/reset breaker
* If your unit does not start after reset-
ting the breaker, check the telephone
book for a HOOVER COMPANY listing;
or consult the Yellow Pages of your
Telephone Directory for the nearest
location where approved service and
genuine HOOVER replacement parts
may be obtained. For service under
warranty, follow the instructions in the
warranty provided with this product.
Always identify your cleaner by model
number when requesting information or
ordering replacement parts.
• 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 Hoover Factory
Service Center.
Problem: Suction low
Possible cause
Possible solution
• Filter dirty
• 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 block-
age.
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 rapid-
ly several times. If this does not
clear the blockage, contact your
local Hoover Factory 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 misposi-
tioned
• Check to see if the dirt container
needs to be emptied.
Check to see if the dirt bucket is
properly positioned and securely
clamped shut.
