Installation
dOs & dOn’TsuniT insTallaTiOn
Using the mounting plate provided with
your vacuum cleaner, secure the unit to
the wall (figure 1), at a height allowing
easy access for maintenance of the
filters, dirt receptacle and/or bags (see
pages 6 and 7).
The connections to the piping system
will require some basic tools: a mitre
box and small saw or a pipe cutter
(figure 2). See pages 9 and 10 for
general instructions pertaining to the
preparation of PVC pipes. To simplify
matters, installation kits, including
necessary fittings, pipes, glue and
wiring, as well as a detailed instructions
booklet, are available from Mvac service
centers.
Contrary to all other connections
in the piping system, do not glue
the last fitting to your unit. Mvac
central vacuums are equipped with an
adjustable air intake valve (figure 3),
which does not require glue. An air-
tight fit is achieved with the screw-type
adjustment on the fitting itself.

INSTALLING INLETS
When installing your vacuum inlets, we recommend that the principle of electric
polarity be taken into account. Ensure that the wire connected onto contact A
on inlet 1 is the same as that connected to contact A on inlet 2, and so on. Do
not cross, reverse or interchange wires.

There should be an electric outlet within 1 meter (3 feet) of your central
vacuum unit. Once the appliance is installed in a suitable location, connect your
central unit to an electric outlet on an dedicated* grounded circuit. Do not
use extension cords or modify the length of your vacuum cleaner’s power cord.
DEDICATED* GROUNDED CIRCUIT
• North America
120 V / 240 V All models: 15 A
• European continent and other
220 V / 240 V Model M11: 10 A
220 V /240 V All other models: 8 A
Your central vacuum cleaner has a thermal safety device or a circuit breaker to
protect against any over voltage or electrical defect. If that protection should
fail, contact your authorized service center.
*Please reserve a circuit breaker dedicated only to the connections for your
central vacuum.
If you find that installing your vacuum cleaner is too difficult, ask your
service center to install it for you. When in doubt, it is better to have
the work done by a professional and ensure that the unit is properly
installed. Any installation that does not comply with the specified norms
could alter or invalidate the warranty.

Installation
This appliance must be grounded. If it should malfunction or breakdown,
grounding provides a path of least resistance for electric current to reduce
the risk of electric shock. This appliance is equipped with a cord having an
equipment-grounding conductor and grounding plug. The plug must be inserted
into an appropriate outlet that is properly installed and grounded in accordance
with all local codes and ordinances. No adaptor should be used with this
appliance.
WARNING
Improper connection of the equipment-grounding 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. Do not modify the plug
provided with the appliance – if it will not fit the outlet; have a proper outlet
installed by a qualified electrician.
120 V MODELS
This appliance is for use on a nominal 120 V circuit,
and has a grounded plug (figure 4). Make sure that the
appliance is connected to an outlet having the same
configuration as the plug. No adaptor should be used with
this appliance.
220 V/240 V MODELS
This appliance is for use on a circuit having a nominal rating more than 120V and
is factory-equipped with a specific cord and plug to permit connection to a proper
electric circuit. Make sure that the appliance is connected to an outlet having the
same configuration as the plug. No adaptor should be used with this appliance. If
the appliance must be reconnected for use on a different type of electric circuit,
the reconnections should be made by a qualified service personnel.
GrOundinG insTruCTiOns lOw VOlTaGe COnneCTiOns
Connect the low voltage wires to the low
voltage inlet on your unit. To do so, simply
strip wires over 1/2 cm (1/4"), remove the
terminals from the low voltage inlet on the
unit, and proceed according to the types of
inlet and wire used.
STANDARD LOW VOLTAGE INLET
All types of wire
Twist the stranded wire to tighten the
loose strands together before proceeding.
Insert the wire into the terminal (blue
connector). Using your wire strippers,
tighten the terminal at two places: at the
front, to hold the wire in place, and at
the back to tighten the insulator around
the wire (figure 5). If the insulator does
not completely cover the stripped wire,
use electrical tape to insulate the wire
adquately, and prevent all contact between
the 2 wires. Insert the terminal into the
low voltage inlet (figure 6).
To disconnect
Do not pull on wire. Simply remove the
terminal from the low voltage inlet.

“EASY CLIP” INLETS ONLY
Stranded Wires
Twist the wire to tighten the loose strands
together, and insert into the terminal (yellow
connector). Using your wire strippers, tighten
the terminal at two places: at the front, to hold
the wire in place, and at the back to tighten
the insulator around the wire (figure 7). If
the insulator does not completely cover the
stripped wire, use electrical tape to insulate
the wire adquately, and prevent all contact
between the 2 wires. Insert the terminal into
the low voltage inlet (figure 8).
Solid Wires
Having previously removed the terminals
(blue connectors) from the low voltage inlet
on your unit, simply insert the wire directly
into the inlet (figure 9).
To disconnect
Simply press on the corresponding release
button, and pull out wire or terminal with
wire (figure 10).
Note: When using stranded wires and
terminals, do not pull on wire itself, but grasp
the terminals to disconnect.
lOw VOlTaGe COnneCTiOns
Your Mvac central vacuum unit (except
M4 model) was designed for use with or
without disposable bag. Though it is sold with
a bag installed, it can easily be removed, and
the unit modified for use without disposable
bags.
1. To access the bag, unlatch the two clips and
remove the dust receptacle (figure 11).
2. Remove the used bag (figure 12). If it
has been used, seal its opening with the
self-adhesive flap on the bag collar (see
instructions on the bag). Discard the used
bag. If the bag was not utilized, you may
wish to store it for later use.
3. Loosen the screw on the bag adaptor
clamp.
4. Remove the bag adaptor (figure 13), and
store for later use, if needed.
5. The vacuum unit is now ready for use
without bags.
Note: this procedure is reversible at any time.

Operating Instructions
hOse hOOk-uP & inleTs
BEFORE OPERATING YOUR CENTRAL VACUUM…
Please verify that it is properly connected to the piping system, and to a
grounded electrical outlet, and that the low voltage wires are connected to the
unit (see pages 8 to 16). Then read the complete owner’s manual and proceed
with a quick verification of your unit’s installation:
• Check filter and bag to be sure they are properly installed.
• Check rubber seals in each vacuum inlet.
• Plug the hose alternatively into each vacuum inlet, to ensure that each one
works properly.
• While the hose is still plugged into one inlet and the system is operational,
check other inlets for leaks.
To start your central vacuum, simply insert the hose in the vacuum inlet of your
choice. Please ensure that the tab on the hose end is properly lined up with the
slot in the inlet opening (figure 14). If your hose handle has an integrated on/off
switch, simply slide the switch to the “on” position.
Do not try to open another inlet while your system is in operation, as it
may damage the inlet’s rubber seal.
