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.
Operation
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.
WARNING:
Improper connection of the equipment-grounding (earthing) conductor can
result in a risk of electric shock. Check with a qualified electrician or service
person if you are in doubt as to whether the outlet is properly grounded
(earthed). Do not modify the plug provided with the appliance. If it will not fit
the outlet, have the proper outlet installed by a qualified electrician. This
appliance is for use on a nominal 120 volt (see rating plate for correct
voltage) circuit and has a ground (earth) plug that looks like the plug
illustrated in Figure 2. Make sure that the appliance is connected to an
outlet having the same configuration as the plug. No adapter should be
used with this appliance.
• If the power cable is damaged, use only an OEM replacement cable.
• Check the power unit on/off button and all inlet valves for operation.
• This power unit is intended for household and commercial use only.

Installation Of Power Unit
The power unit hangs on the mounting bracket
which is screwed to the wall. The bottom screws
of the mounting bracket should be about 48”
(122 cm) up from the floor to allow convenient
removal of the dirt receptacle. For proper motor
cooling, there must be at least 12” (31 cm)
between unit and the ceiling (see Figure 1). If
mounting on plaster or panel walls, be sure
mounting screws enter studs. If mounting on
concrete wall, drill the wall with a masonry bit
and insert the appropriate wall anchors. Strip
the low-voltage wires that were installed with
the main trunk line. Connect the wires to the
spring loaded connectors on the back side of
the power unit. Connect the main tube line to
the left side of the power unit with the connector
and clamp provided. Do not cement this
connection to the power unit in case you wish
to remove at some future date. NOTE: For
paper bag units, follow directions provided with
unit. This unit may be vented outside to exhaust
fumes and germs. For optimum noise reduction,
this unit must be vented outside. Use the same
tubing and fittings as before. Do not vent power
unit exhaust into a wall, ceiling or concealed
space of a building. Use two exhaust lines for
twin motor units. NOTE: On/off button on
power unit is only used for the inlet on power
unit. All other inlets operate automatically when
hose end is inserted into inlet valve. The power
cable has a three-prong female connector on
one end. This connector must be plugged into
the mating connector on the power unit. Plug
the other end of the power cable into the wall
electrical outlet. WIRING: Check local codes,
but use not less than #12-2 wire with ground.
Plug power unit cord into appropriate electrical
outlet. Be sure line voltage is sufficient to
handle 20 amp load.
Grounding (Earthing)
Instructions
This appliance must be grounded (earthed). If it
should malfunction or break down, grounding
(earthing) provides a path of least resistance or
electric current to reduce the risk of electric shock.
This appliance is equipped with a cord having
an equipment-grounding (earthing) plug. The
plug must be plugged into an appropriate outlet
that is properly installed and grounded (earthed)
in accordance with all local codes and ordinances.
