Cyclo Vac Central vacuum system Owner's Manual page 31

PROBLEM
Note:
the hose switch for one full second to shut off central vacuum.
Troubleshooting
POSSIBLE CAUSE
Hose improperly inserted
into vacuum inlet
Defective on/off hose
Low voltage wire is not
connected properly
Troubleshooting
CORRECTIVE ACTION
Ensure that the hose
end is properly placed
in the vacuum inlet: the
tab on the hose should
fit into the slots of the
inlet to ensure adequate
contacts for the hose
switch to function (see
page 17).
If the hose is properly
placed in the vacuum
inlet, and the unit
continues running
despite the fact that
the hose switch is in
the "off" position, have
the hose checked by a
service center.
While the vacuum is on,
unplug the low voltage
wires from the unit. If the
vacuum stops, there's a
faulty low voltage wire.
Contact your installer
or authorized service
center.
