Congratulations! You are now the proud owner of a Electrolux Built-in Vacuum System . . . . . the
ultimate in cleaning equipment. Say "good-bye" to old fashioned sweepers. You'll never have to
lug a heavy, awkward vacuum again. Your Electrolux Built-in Vacuum will change your cleaning
routine. It is so easy and versatile to use. It's quiet and dust-free. It will help eliminate the drudgery
of vacuuming and give you a cleaner, healthier indoor environment. Before you use your Electrolux
Built-in Vacuum System, read this manual carefully. Learning the proper way to use this system will
help give you years of trouble-free cleaning performance.


To operate, simply plug the hose into one of the
handy wall inlet valves. The metal ring on the
cutoff of the hose will complete a low-voltage
electrical circuit, which in turn activates a relay
and turns on the system's power unit. To turn
off the power unit, simply unplug the hose from
the inlet. Please Note: When unplugging the
hose, it is recommended to hold the inlet door
open for a few seconds until the suction
pressure has sufficiently decreased. For safety
purposes, a low-voltage circuit is utilized at the
wall inlet. The power unit functions on a standard
110/120-volt circuit. There are optional hoses
available with an on/off switch located on the
handle. Please note: When using one of these
optional hoses, it is important to properly align
the hose with the wall inlet when plugging it in to
prevent damage to the unit.

Power Unit

Electrolux power units are equipped with
115/120-volt by-pass motors. Electrolux power
units also employ a manual reset circuit
breaker. Electrolux's self-cleaning filter provides
complete protection of the motor fan assembly.
It is normal for some dirt and lint to cling to the
filter. However, the filter should be checked
occasionally to be sure it has not been punc-
tured or torn. The dirt receptacle should be
emptied two or three times a year on the
average depending on the amount of use. For
best results, empty the canister when it is about
half full. Any dirt spilled can be vacuumed up
quickly by plugging the hose into the utility inlet
located on the power unit. The on/off button on
the power unit will start and stop the power
unit. No part of the unit requires lubrication.
Electrical Fault Protection
The central vacuum system employs features
that monitor the following operating levels:
AC voltage, current draw and circuit board
temperature. If the voltage is below or above
the standard operating voltage, high current
draw or locked rotor, the power unit will not
operate. In this case the LED next to the on/off
button will blink until the problem ceases. If the
circuit board reaches an elevated temperature,
the power unit will not operate and the LED will
be off. In the event of these problems happening,
press the on/off button, unplug hose, or wait for
temperature to lower. If problems persist; contact
the authorized service center nearest you.
In the case of power failure, the power unit will
return to its previous state when power returns.
For example, if a hose is plugged in with the
hose switch on, or a straight air hose is plugged
into a wall valve, then the power unit will turn
back on. If the power unit was turned on at the
unit prior to power loss then the unit will not
turn back on.
Hose Use And Care
For optimum benefit, the hose should be used
and stored at temperatures above 40˚F (5˚C).
Always hang up the hose when not in use using
the hose hanger supplied. If hose should
become clogged, insert the wand end into the
utility inlet on the power unit. Turn on the power
unit with the manual switch and seal the extra
air-space by holding the hose firmly. The
obstruction should be quickly vacuumed out. If,
however, the hose remains clogged, insert an
electrician's fish tape (wire) or garden hose
through the hose to remove the obstruction,
being careful not to puncture the hose.
Disconnect hose handle from wands before
storing. DO NOT store hose in direct sunlight.
