INTRODUCTION
IMPORTANT
Apartment-specic
ventilation units allows
residents to adjust the
ventilation efciency.
Ventilation is controlled
based on the need e.g.
through the cooker
hood, ventilation control
panel, or a separate
control centre. In order
to ensure that the
indoor air presents no
harm to health and
remains optimal also
for the structures of the
building, ventilation
must be kept on
without disruptions.
It is recommended that
ventilation be left turned
on during long holidays
also. This keeps the
indoor air fresh and
prevents humidity
from condensing in
the ventilation ducts
and structures. It also
reduces the risk of
moisture damage.
VENTILATION UNIT CONTROL
Ventilation unit control options.
Ventilation has to be constant for the indoor air to stay healthy
for the dwellers and the structures of the dwelling. Even for
longer holidays, it is not advisable to stop the ventilation,
because the indoor air will become stuffy and, during the
heating season, the indoor air humidity may condense in the
ventilation ductwork and structures, causing moisture damage.
You can control and automate the ventilation unit operation in
the following ways:
- By using an Adroit control panel installed in the building
- Through the Adroit Home local network connection and the
Web interface
- Through the Adroit Cloud Service and the Web interface
- Through a remote monitoring service or building automation
by using voltage signals or Modbus messages
- By using the front panel of the cooker hood; this control option
applies only to the DV51CH.
At home
Use this mode when the dwelling is occupied.
Away
Use this ventilation mode when the apartment is
unoccupied, e.g. during a trip or other long absence.
Boost
Fireplace mode
Use this mode when starting a re in the replace.
The mode is primarily used to create a short period
of overpressure in the dwelling, stopping spillage of
smoke back into the property.
Use this mode to increase the ventilation rate,
e.g. when there are more people than usual in
the dwelling and for rapid clearance of air-born
contaminants.
Changing the ventilation mode
Adroit DV51
The Adroit DV51 ventilation unit is controlled by using the Adroit
Control panel. Press the left button of the control panel (See
icons below) repeatedly until the desired status is shown as the
middle option on the display.
Adroit Control panel

Cooker hood light
Turn the light on or off by pressing the light switch. The
brightness of the light can be adjusted. See page 7.
Ventilation modes
Select the mode by pressing the fan speed button
repeatedly until the signal light indicates the desired
ventilation mode:
Away mode
Use this ventilation mode when the apartment is
unoccupied, e.g. during a trip or other long absence.
At home mode
Use this mode when the dwelling is normally occupied.
Boost mode
Use this mode to enhance ventilation, e.g. when there
are more people than usual in the apartment and for the
rapid clearance of airborne contaminants
Selection button
The selection button is roughly 2 cm to the left from the
light switch.
CAUTION
• Neglecting the
cleaning of the grease
lter can cause a re
hazard.
• The outer surfaces of
the hood can become
hot when the cooker or
the oven is turned on.
• Flaming is forbidden
underneath the cooker
hood.
• Always follow the
instructions provided on
adjusting the efciency
of ventilation.
• A sufcient supply air
ow must be ensured in
the room if the cooker
hood is to be used
simultaneously with
non-electronic devices.
Adroit DV51CH
The Adroit DV51CH ventilation unit is controlled by using the
Adroit cooker hood that is connected to the unit. The cooker
hood is designed to be used above the cooker top, as a general
extraction valve in the kitchen, and as a ventilation system
control panel.
The front panel of the cooker hood has four control buttons.
Position of the damper
The damper is opened by pressing the damper button
(signal light turns on). The damper is closed (signal light
turns off) by pressing the damper button or automatically
after one hour (without a timer or adjustable from 45 to
120 min when programmed).
In normal circumstances, the damper must be closed (the
signal light is off), which boosts the extract air ow from other
premises.
The damper must be open (the signal light is turned on) when
theuserwantstoincreasetheextractairowfromthe
cooker hood e.g.
• when the cooker top or the oven is used for cooking;
• the load in the kitchen is exceptional due to the use of
strong detergents, presence of a large number of people, or
similar.

MOUNTING ON THE WALL
NOTE
Avoid mounting the unit on a hollow, echoing partition wall or on
a bedroom wall, or prevent the conduction of sound.
Note that during mounting the unit rises 10 mm higher than the
nal height.
Mount the ventilation unit on the wall with a mounting plate, as shown
in the adjacent gure. Make sure that the unit is horizontally level after
mounting.
Adroit DV51CH must be mounted so that the clearance between the
bottom of the cooker hood and the cooker top is at least 426 mm
in case of an electric stove and 650 mm in case a gas stove. The
clearance is 134 mm (i.e. the height of the cooker hood) more between
the bottom of the ventilation unit and the cooker top.
EXTERNAL ELECTRICAL CONNECTIONS
External electrical connections are led to the ventilation unit through
the ceiling bushing for electric connections. The length of the wires
must enable pulling the fan chamber assembly out of the unit without
having to disconnect any of the connections.
NOTE
A space of at least 330
mm must be reserved
in front of the unit for
maintenance purposes.

REMOVAL OF CONDENSING WATER
Adroit DV51
The Silent Klick siphon is installed in the bottom pool of Adroit
DV51. The condensing water tube is led from the siphon e.g. to the
siphon of the sink or to the oor drain. Alternatively, an elbow can be
installed in the bottom pool, in which case the Silent Klick siphon
is installed in the condensing water tube to enable maintenance
measures.
NOTE
The Adroit Silent Klick
siphon package is
delivered with Adroit
DV51CH and DV51.
Installation instructions
for the siphon are
enclosed with the
packaging, and can
also be found online at
www.airow.com. When
the alternative siphon
installation method is

Adroit DV51CH
In Adroit DV51CH, an elbow is mounted on the bottom pool
between the unit and the cooker hood. Condensing water tube
is led from the elbow e.g. into the siphon of the sink or the oor
drain. The siphon must not be installed inside the cooker hood.
Instead, it must be installed in the condensing water tube so as
to enable maintenance measures. There are approx. 2 mm wide
holes at the rear of the bottom of the Adroit DV51CH ventilation
unit marking the position where the condensing water tube must
be installed.
1. Install the elbow at the bottom of the ventilation unit without
the siphon (Figure 1). Install the siphon in the condensing
water tube before the drain or odour trap (Figure 2). The
Silent Klick siphon helps prevent noise disturbance caused
by the removal of condensing water.
2. The condensing water tube must be installed either directly
backwards from the cooker hood through the wall, if there
is a sewer connection behind the wall (see gure 2 for the
dimensions of the tube location), or to the odour trap of the
sink (Figure 2).
3. 3. The condensing water pipe must be placed at an
angle so that it always points downwards, enabling the
condensation to drain away from the unit.

The accessories delivered with the unit include four (4) air ow
measuring tubes. These can be inserted in the ducts to allow for
easier ventilation adjustment.
MEASURING AND ADJUSTING THE AIR
FLOW RATES OF THE COOKER HOOD
Standard ventilation
The volume ow rate of the air inside the cooker hood is measured
with the damper closed and, where required, adjusted based on
the static pressure loss and the performance scheme of the cooker
hood.
• The static pressure loss is measured from the hole in the
damper using the measuring tube found in the accessory bag
(see Figure).
• Determine the volume ow rate from the performance scheme
based on the measured pressure and the number of open
holes in the damper.
Adjustment:
• Cover the required number of holes in the damper with the
magnetic strip that is delivered with the cooker hood.

BEFORE BEGINNING
MAINTENANCE WORK
WARNING
Always disconnect the power plug before starting
maintenance on the ventilation unit. The unit has no
safety switch that would switch the power off when
the door of the unit is opened.
CHANGING THE FILTERS
The Adroit ventilation unit has three lters:
• Coarse lter for supply air lters insects, heavy pollen
and other relatively large foreign objects out of the
outdoor air.
• Fine lter for supply air lters microscopic pollen and
dust particles out of the supply air.
• Coarse lter for extract air lters the extract air and
keeps the heat recovery cell clean.
The lter replacement interval depends on the ambient
particle concentration. It is recommended that the lters
be replaced every spring and autumn, or at the very least
once a year.
To replace the lters:
1. Disconnect the ventilation unit from the mains
electricity supply.
2. Open the door of the unit.
CAUTION
The door is heavy.
3. Remove the old lters (A, B, C) and discard them.
4. Install the new lters (A, B, C).
5. Close the door of the unit.
6. Plug the ventilation unit back into the mains.
7. The lters have now been successfully replaced.
TIP
Using original Adroit
lters ensures that the
ventilation unit remains
in top condition, giving
the best results. To
select and order lter
packages, please go to:

CLEANING THE HEAT RECOVERY
CELL
Check that the heat recovery cell is clean roughly once a year,
or whenever the lters are being replaced. Clean by washing
as required.
IMPORTANT
If the unit has an enthalpy cell, it must not be washed.
Only aluminium or plastic cells can be washed.
Cleaning the heat recovery cell:
1. Disconnect the ventilation unit from the mains electricity
supply.
2. Open the door of the ventilation unit by undoing the nger
screws and by lifting the door off.
CAUTION
The door is heavy.
3. Pull out the black upper support of the cell (E) located
above the cell.
4. Lift and pull the cell (D) out of the unit.
IMPORTANT
Handle the cell carefully! Do not lift the cell by the layers.
The cell layers are very thin and easily damaged.
5. If the cell is dirty, clean it by immersing it in warm water, to
which a small amount of a mild detergent has been added.
6. Rinse the cell clean with a water spray. Do not use a high-
pressure cleaner.
7. When all the water has drained from between the layers,
reassemble the ventilation unit in the reverse order.
8. Close the door.
9. Plug the ventilation unit back into the mains. The heat
recovery cell has now been cleaned.
MAINTENANCE
CONDENSING WATER
In the heating season, the extract air humidity condenses to
water. In new buildings, condensation discharge can form
rapidly. Condensed water must be able to freely leave the unit.
At some time before the heating season begins (e.g. during
autumn maintenance), check that the siphon or the condensing
water outlet in the bottom pool are not clogged. To check this,
pour some water into the pool. Clean as required.
NOTE
Some condensing
water may have
accumulated in the
bottom pool of the
unit; this is normal and
requires no corrective
action.
WARNING
Water must at all times
be kept out of the
electrical system.

CLEANING THE FANS
Check the cleanliness of the fans when servicing the lters and
the heat recovery cell. Clean the fans as required.
Removing and cleaning the fans
To clean the fans:
1. Disconnect the ventilation unit from the mains electricity
supply.
2. Undo the door screws to open the door of the Adroit
ventilation unit.
3. Lift the door off.
CAUTION
The door is heavy.
4. If the length of the cables that are led out of the unit through
the ceiling bushing grommets (G) and connected to the
connection card (F) in the electric box prevents moving
the fan chamber sufciently far from the ventilation unit,
disconnect the cables. Pull these cables out of the unit
through the ceiling bushing.
5. Detach outdoor and extract air temperature sensors from the
ceiling mounts. Remove the round feedthrough rubbers (H)
from the slots on the intermediate walls of the unit by pulling.
6. Undo the earthing screw (K) on the upper left corner of the
electric box.
7. Release the damper motor (J) by placing an orange magnet
(I) on the magnet icon on the damper motor. Observe the
location of the magnet so that you will be able to return it to its
original location after maintenance. Remove the bar from the
joint of the damper. Turn the crank of the damper motor so
that the bar comes off from the bypass damper and turn the
damper into the cell bypass position.
8. Pull out the upper support of the cell (E). Lift and pull the cell
(D) out of the unit.
9. Pull the fan chamber (K) out of the unit (contains the fans,
electric box, and the bypass duct incl. the damper motor).
10. The fans are mounted on the fan chamber by means of three
screws (L). Do not undo the earthing screw at the bottom
edge on the rear wall side.
11. Disconnect the quick connectors of the fan cable.
12. Clean the fans. The fan can be cleaned with compressed air
(wear protective goggles) or by brushing it gently.
13. To reassemble the ventilation unit, follow the above steps in
reverse order.
NOTE! Remember to reconnect the bar of the damper motor
into the joint of the damper and to lock the connection
with the orange magnet. Ensure that the sensors and their
feedthrough rubbers are in correct locations. Also ensure
that all the connections have been correctly implemented
and the earthing screw is in place in the left corner.
MAINTENANCE
IMPORTANT
The fans are
extremely sensitive
to external shocks. It
is recommended that
the fans be cleaned
in place, i.e. without
attempting to remove
them. Handle the fan
blades carefully.
It is recommended that
the fans be cleaned by
a professional.
