Installation space
Duo is small and quiet. The Duo central unit is meant to be installed in dry rooms or storage
spaces. The temperature in the installation space should not be below +5 C or above +35
C, even when the vacuum cleaner is used. Do not store or handle flammable or corrosive
substances in the same space with the central unit.
Connect the exhaust coupling to the exhaust pipe which leads outside using a twist hose, or,
if that is not possible, purchase a separate HEPA exhaust air filter. The HEPA filter cleans
the vacuumed air before returning it to the installation space of the vacuum cleaner. If the
exhaust air is led back indoors, place the central unit in a well-ventilated location.
When the central unit is installed in a closet, cooling ventilation is prevented, and additional
ventilation holes should be made. Make the holes level with or below the bottom of the Duo
unit, as well as above the unit, and in any shelves in between. The size of the hole must
be at least 6 x Ø 50 mm, or e.g. 30 x 400 mm (or the width of the doorframe). Do not cover
the cooling ventilation holes. Attach the central unit to a 230 V wall socket, protected with at
least a 10 A slow plug fuse, or a 16 A automatic fuse. The length of the power supply cord
in Duo is 150 cm. Please ensure that the plug can be accessed after installation.
The exhaust air muffler and the silencer for exhaust air are accessories. For more instructions
on installing the pipes and wall inlets, please see the pipe kits. All instructions can also be
found on the web site:

Mounting the central unit
The Duo unit comes with a wall bracket suitable for different kinds of wall structures. Mount
the unit in one of the following ways (see pictures 5–7). Keep the wall material and thickness
in mind when choosing suitable mounting screws.
5
Screw the Duo unit to a shelf or a wall through the screw holes in the bottom of the unit.
6
Attach the wall bracket to the bottom of the unit with two screws. Screw one screw into the
wall and lift the unit hanging on the screw. Screw in the highest two screws.
7
Screw the wall bracket onto a shelf or a wall with four screws. Suspend the unit from the
wall bracket. Lock the unit to the bracket with two screws.

SERVICE
Note any maintenance actions in the maintenance log at the end of the manual. Always use
original Allaway equipment with the Duo.
Power cord
If the power cord of the central unit is damaged, it should be replaced with a special power
cord from the manufacturer in an authorised Allaway maintenance company.

Changing the dust bag
ALWAYS use Allaway microfibre dust bags on the Duo unit. Replace the dust bag before
it is completely full. Unplug the power cord from the wall socket. Remove the used dust bag
from its holder. Clean the dust bag space. Take a new dust bag from its packing, and puff
it with your hands. Attach the new dust bag to the dust bag holder. The dust bag package
contains a shutter sticker that can be used to close the used dust bag.
Maintenance of the turbine filter
The turbine filter protects the turbine, in case the dust bag gets damaged. The filter must be
intact and in place. When servicing the filter, remove the power cord from the socket. Clean
the filter with water. If the filter is damaged, replace it.
Maintenance of the HEPA exhaust air filter
The Duo Aparto Kit contains a HEPA exhaust air filter that cleans the vacuumed air before
returning it to the surroundings of the vacuum cleaner. The HEPA filter is also available as
an accessory. Remove the power cord from the socket when servicing the filter. The filter
may be cleaned with water, but avoid scrubbing. The filter must be intact and in place.
Replace the filter if it is damaged, after every fifth change of the dust bag, or every three
years, whichever is the sooner. It may be necessary to replace the filter at an earlier stage
if it is blocked or has absorbed odours. Mark the date of changing the exhaust air filter on
the side of the filter using a permanent marker.
Maintenance support
For maintenance instructions and useful tips, please go to www.allaway.com. A list of
authorised Allaway maintenance companies is also available.
There are no parts for the user to maintain inside the central unit's motor housing. We
recommend that the need for maintenance and replacement for the electric motor's turbine
and other parts inside the motor housing are estimated by an authorised Allaway service
dealer after approx. 600 hours of use. This corresponds to approx. 8 years when the device
is used an average of an hour and a half per week.
Machine information for maintenance
Before contacting the authorised Allaway maintenance company, write down the type and
serial numbers from the name plate on the turbine casing. Do not drop the machine or
expose it to impact.
