EMEDY

1. Loss or

decrease
of vacuum
occurs.

• The plastic cap is not installed on

the unused inlet.

• Debris pail or disposable bag is

completely full.

• 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.

• Wall inlet cover not properly

sealed.

• Place the included plastic cap on

the unused inlet opening.

• Change disposable bag or empty

debris pail as described on page 4.

NOTE: Clean secondary filter if 

necessary.

• 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 with

power unit running, 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.

• Check all wall inlet covers to be sure

they are closed and sealed tightly.

2. Power unit

does not
start or
stops 
suddenly.

• Defective inlet. Check other wall inlets.
• Power unit overcurrent protector

has been activated.

• Blown fuse or tripped circuit

breaker on house electrical panel.

• Thermoprotector has been 

activated.

• Defective hose.

• Replace defective wall inlet.
• Turn the unit off by using the

power switch on the unit. Check
the overcurrent protector button
located on the left side of the
power unit (push to reset the 
system). Turn unit back on.

• Replace fuse or reset circuit

breaker on house electrical panel.

• Turn the unit off by using the

power switch on the unit. Wait 
30 minutes to let the unit cool
down. Turn unit back on.

• Replace hose as required.

3. Power unit

fails to stop
when the
hose is
removed.

• An electrical short has occurred

somewhere in the system.

• A complete check of all wall inlets

and power unit low voltage control
leads connections.
Contact your authorized Service
Center.
