REMEDY
1. Loss or decrease of
suction occurs.
• Debris pail or disposable bag is completely full.
• Debris pail gasket damaged or missing.
• Obstruction in the hose. A blockage in the hose
can be determined by inserting the hose into
any wall inlet and, while power unit is running,
check each additional inlet for normal suction
by holding the palm of your hand over the
open inlet. If normal suction is felt at all other
inlets, insert the hose into a second inlet. If the
blockage still exists it is located in the hose.
However, if the blockage does not occur when
the hose is changed, the blockage is probably
located in the tubing system leading to the
original inlet.
• Obstruction in the tubing system inside the
walls.
• Permanent filter or disposable bag torn.
• Wall inlet cover not properly sealed.
• Exhaust tubing or vent clogged.
• Change the disposable bag or empty debris pail
as described on page 10.
• Replace the debris pail gasket.
• Disconnect the hose from the wall inlet and
insert a blunt instrument into the hose —
slightly smaller in diameter — such as a flexible
garden hose. Push the garden hose through the
cleaning system hose until the obstruction has
been cleared.
• Insert hose end into any inlet to make power unit
running, then place the palm of your hand over
the opposite end of the hose. When you can feel
the suction increase, hold your hand over the
hose end for a few seconds and then quickly
remove your hand. This procedure repeated
several times should clear the obstruction. If the
blockage is not cleared, contact your nearest
Service Center.
• Clean the interior or the unit and install a new
permanent filter (or disposable bag).
• Check all wall inlet covers to be sure they are
closed and sealed tightly.
• Inspect and remove any blockages.
2.
Power unit does
not start, or stops
suddenly.
• Defective inlet. Check other wall inlets.
• Power unit internal circuit breaker has been
activated (the reset button is popped up).
• Blown fuse or tripped circuit breaker on house
electrical panel.
• Defective hose.
• Power unit overcurrent protector has been
activated.
3.
Power unit runs
continuously when
the hose is removed.
• The unit power switch is in ON position.
• An electrical short has occurred somewhere in
the system.
• Set the unit power switch to OFF position.
• Perform a complete check of all wall inlets and
power unit low voltage control lead connections.
Contact your authorized Service Center.
• Replace defective wall inlet.
• Push on the circuit
breaker reset
button located on
the left side of
the power unit. If
this button pops
up again, contact
your authorized
Service Center.
• Replace fuse or reset circuit breaker on house
electrical panel. Ensure the circuit is DEDICATED
to the central vacuum unit, meaning that there
is no other electrical device connected to the
central vacuum unit circuit.
• Some brands of house panel breakers may be
more sensitive to startup current than others (for
example, Square D brand). Correct the situation
by changing the breaker with an “HM” type
of
the same AMP rating
.
• Replace hose as required.
• Unplug the power unit, wait at least 15 minutes
and plug the power unit back in.
