3. 3. 3. 3. 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. 4. 4. 4. 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. 5. 5. 5. 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. 6. 6. 6. 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. 7. 7. 7. 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. 8. 8. 8. 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. 9. 9. 9. 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

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
11.
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.
