1.
power Cord
make sure that the power cord is plugged into the
power point and that the power point is working
and is turned on.
2.
unit Circuit Breaker or fuse
If your unit has a circuit breaker, it may have tripped
(popped out) due to overheating or a power spike.
Check the button and push to reset. If the button
pops out again call your service technician. on units
with fuses, check and replace with correct fuse. If
the fuse blows again, call for service.
3.
home Circuit Breaker
Check your home electrical fuse/breaker board. If
the fuse has blown or circuit breaker tripped, there
may be too many electrical appliances on the same
circuit. you may need to unplug some of these
or move some to another circuit. If the problem
continues you may need to call your electrician.
4.
unit thermal switch (some models)
Some Vacuum models have an internal thermal
switch that when overheated will stop the unit
running. It may require a period of 10 to 20 minutes
to cool before it will automatically reset.
5.
electrical power point
Check that the power point is working by plugging
a lamp or other electrical device into the point. If
faulty, the Vacuum can be plugged into another
power point if available nearby while you have your
electrician rectify the fault.
6.
Wall Inlet switch stuck off
to check, plug your flexible hose into another wall
valve. If that works, the inoperative wall valve may
have a loose or faulty micro switch, or the hose metal
band may not be making contact with pin jacks on
the valve. the cable fixed to the rear of the valve
may have become dislodged. If the switch can't be
tightened or if the problem is not obvious you will
need to call your service technician.
7.
Wall Inlet switch stuck on
If your wall valve has a micro switch (older models
and utility valves only), check that the steel ball
located at the neck of the valve inlet is not stuck.
Rolling the ball with your finger may loosen any
iCentral Central Vacuum Systems
foreign material lodged there that may have trapped
the ball. If the Vacuum continues to run, turn the
power unit off at the power point and call your
service technician.
If your wall valve has two pins inside the neck (most
modern models) check that the pins are not broken
off and can retract freely when pushed in.
8.
low voltage wire broken
Usually, if more than one wall valve is inoperative
the problem may be caused by a fault in the
low voltage cable. If the cable is only terminated
behind each valve and at the power unit, a visual
inspection may locate the problem. If the cable is
faulty behind a wall, your service technician will
likely be required. In the even that a broken cable
exists in an inaccessible location, the addition of a
wireless switching device may be required to rectify
the problem.
9.
low voltage wire shorted
Unplug the low voltage wiring at the power Unit.
If that stops the unit running, there will be a short
circuit in the wiring or a wall valve may have a stuck
switch, as outlined in "7" above. If the unit does not
stop, there will be a fault inside the unit as outlined in
"20" below, and will require your service technician
to carry out any repairs.
10. flexible hose blocked
If airflow through the hose is poor, remove the hose
from the wall valve, and start the power unit by
pushing the metal ball in the valve or by shorting
out the two pins. If the airflow at the valve is good,
there will likely be a blockage in the hose or wand.
If the blockage is in the wand, it can be disassembled
and cleaned.
If the blockage is in the hose, lay the hose out
straight, then with the hose plugged into the wall
valve and the power unit running, gently stretch
the hose starting at the furthest end from the valve,
working towards the valve. If this is not successful,
reverse the hose by unscrewing the handle and
hose cuff and swapping them to opposite ends of
the hose (depending on the type of hose and if the
hose ends can be unscrewed) and run the vacuum
by plugging the reversed hose it into the wall.
If that does not clear the blockage, there are
additional options that may help, including:
•
Pushing a long PVC conduit through the hose
