3. Circuit Breaker in House Panel - Check your house breaker panel - If the circuit breaker if off, you may
have too many appliances utilizing that circuit. For best results, your power unit should be on a separate
circuit. Try to remove some of the extra circuit load by unplugging other devices. If the breaker continues
to cut off - call your service technician.
4. Internal Thermal Switch in Unit - If your unit comes equipped with an internal thermal switch and
quits running, it may require 10 minutes to cool off before resetting itself.
5. Electrical Wall Outlet Plug - Sometimes the electric wiring from the house breaker panel to the
wall outlet plug can become loose or broken. Plug a lamp or another electric appliance into the outlet
to assure that you are getting power. If not, call your electrical contractor.
6. Switch in the Wall Inlet Stuck in Off Position - Plug your flexible hose into the other wall inlets
- if your unit functions normally then the problem lies in the switch or remote control circuit to the
inoperative inlet valve. The bolts holding the micro-switch in the inlet valve may have loosened allowing
it to move out of position. Remove the wall inlet face plate and tighten the bolts or call your service man.
7. Switch in the Wall Inlet Stuck in On Position - Use your finger to roll the steel ball located in the
top of the neck of the inlet. Some foreign material may have become lodged in the hole with the
ball, preventing it from moving into its proper position. Caution: if this procedure does not turn your
unit off, unplug the power cord and notify your service technician.
8. Remote Control Wire - Broken - Usually, if more than one wall inlet is inoperative, the trouble is in the
remote control wiring, and the wire is either loose or broken, and should be tightened
or replaced.
9. Remote Control Wire - Shorted - Unplug one of the remote control wires that is attached to the
side of the power unit - if the unit stops, it indicates that the remote control wire is shorted or one
of the wall inlet switches is stuck in the on position. If the procedure for number 6 does not shut
the unit off and you cannot locate the short, notify your service man. If the unit does not stop
running when you unplug the remote control wire - either the short is in the power unit wiring or
the relay is stuck. Refer to number 20. Caution: Checking the wiring in the power unit should only
be attempted by a qualified service technician.
10. Flexible Hose - Plugged - If proper airflow is not obtained through the hose, remove the hose from
the vacuum inlet, then start the power unit by activating the wall inlet switch. If the airflow, at the
inlet, is good, then this will normally indicate a blockage in the hose or wand. If blockage is in the wand,
it can be disassembled and cleaned. If blockage is in the hose, the hose should first be laid out straight,
then with the hose plugged into the inlet valve and the power unit running, pick up the hose, starting at
the end furthest from the valve and gently stretch about two feet of it at a time as you proceed along the
length of the hose toward the inlet valve. It this does not clear the stoppage, then remove the hose cuffs
by unscrewing them, and switch them to the other ends of the hose (these cuffs have left hand screw
threads so rotate them in a clockwise direction to unscrew from the hose). After this has been done
replace the hose in the inlet valve and with the power unit operating, repeat the process of stretching the
hose. If this fails to unclog the hose, run (handle first) a screwdriver with at least a 3/4” diameter handle
through the hose.
11. Tubing in Wall - Clogged - Check the airflow at the power unit. If the airflow is good here but not at
locations further from the power unit, your tubing is either clogged or has broken open. If you cannot
repair this, contact your service man. If you turn the power unit on and leave the inlet valve furthest from
the power unit open and then check the exhaust from the power unit, you can determine whether you
have a break in the tubing or whether the tubing is clogged. If very little air is coming out of the exhaust
of the power unit, then it is probably an obstruction in the tubing and not a break.
12. Dirt Canister - Over Filled - Whenever low airflow is experienced the first thing to check is the dirt
canister for over filling or clogged filter bag (some models). Refer to Number 13. Read the Operations
section of this manual for information on how to clean your dirt canister.
