MANUAL
VENTILATION CONTROL
The house extraction fan serves as a mechanical air
extraction unit in the apartment, allowing the resident to
adjust the ventilation eciency. The eciency is adjusted
using the ventilation eciency control.
1. Away profile
The ventilation eciency can be temporarily
reduced when the apartment is unoccupied.
2. At home profile
Ventilation must be continuous, i.e. the air
inside the building must be replaced at least
once every two hours.
3. Boost profile
Cooking, sauna, bathing, drying of clothes,
excessive heat, and other similar situations
can require that ventilation be increased
from the standard setting. In such a situation,
ventilation must be increased.
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.
PLEASE NOTE!
• Neglecting the cleaning of the grease filter can cause a
fire hazard.
• The outer surfaces of the house extraction fan can
become hot when the cooker top or the oven is turned on.
• Flaming is forbidden underneath the house extraction fan.
• Always follow the instructions provided on adjusting the
eciency of ventilation.
• Enable a sucient supply air flow into the room if the
house extraction fan and non-electric devices are used
simultaneously.
USING THE UNIT
The house extraction fan has a sliding glass that can be
pulled out of the cooker fan. It is recommended that the
sliding glass be pushed or pulled from the aluminum strip on
its front edge. Pull the glass out of the house extraction fan
for maximal extraction capacity.
Front panel buttons
The front panel of the house extraction fan has four buttons.
Position of the damper
In normal circumstances, the damper must be closed
(the signal light is o ), which boosts the extract air flow from
other premises.
The damper must be open (the signal light turned on)
when the user wants to increase the extract air flow
from the house extraction fan, 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.
House extract fan light
Turn the light on or o by pressing the light switch. The light
is dimmable. Adjust the brightness by pressing the light
switch until the brightness is adequate.
Ventilation profiles
Select the profile by pressing the ventilation profile button
repeatedly until the signal light indicates the desired
ventilation profile.
Away profile

The settings button is roughly 2 cm to the left from the light
switch.
Other functions
Guard function
The house extraction fan is equipped with a guard function
that is activated when the temperature of the house
extraction fan exceeds 60°C or after a sudden increase in
temperature (> 8°C/min). In such a case, all signal lights of
the house extraction fan and the LED light will flash. If this
kind of an alarm is noticed before fire damage, it can be
acknowledged by pressing any of the house extraction fan
buttons.
Pre-setting of light brightness
To modify the pre-setting of light brightness:
1. Turn on the light, close the damper, and set the
ventilation to the Away profile.
2. Press the settings button for roughly 3 seconds until the
setting mode signal light starts to flash.
3. Adjust the brightness of the light by pressing the light
button until the brightness is adequate.
4. To save the setting, press the settings button for roughly
3 seconds until the setting mode signal light stops to
flash.

MAINTENANCE
Keep the house extraction fan clean. Wipe outer surfaces
regularly with water containing a small amount of a mild
detergent. Clean o any grease stains immediately. Do not
use abrasive or corrosive detergents or tools.
Keep the grease filter clean to ensure an adequate extract air
flow. The grease filter must be washed with warm water and
detergent at least 1-2 times a month.
Light
The house extraction fan has a long-lasting LED lighting
module. If the light is not working, contact a ser vicing
company.
INSTALLATION
In the example, the bottom of the sides and the rear of the
house extraction fan are level with the bottom of the top
cabinets (see figures 1-2). In this case, a specially made cover
panel is needed to hide the fan. The height of the cover
panel is roughly 210 mm.
The house extraction fan can also be mounted higher, even
so that it touches the frame of the spice cabinet. In this case,
rear corners need to be sawn o from the spice cabinet
frame (see figure 3). In this mounting method, the height of
the house extraction fan cover panel is 100 mm.
When the lowest possible mounting height is used, the
bottom edge of the sliding glass, when pushed inside the
house extraction fan, is level with the bottom of the top
cabinets (see figure 4). The L strip is mounted on the wall as
shown in figure 5. In this mounting method, the height of the
hood cover panel is roughly 248 mm.
Figure 1.
Remove the spice cabinet. Mount the L strip on the wall so
that it is level.
The L strip fully covers the gap between the house extraction
fan and the wall and also makes it easier to balance the fan in
place during mounting.
If the top cabinet frames are less than 305 mm deep, the
longer edge of the L strip is mounted on the wall. The
perforations on the lower surface of the L strip can be
covered using white plastic studs.
Removing and mounting the grease filter
Removing the filter
• Pull the locking device of the grease filter towards the
front edge of the house extraction fan while pulling the
grease filter downwards until it comes o.
• Wash the grease filter and leave to dry.
• Mount the grease filter back in place. Push the front
edge of the filter into the pins on the cooker hood, and
click the rear edge in place.
NOTE! Ensure that the locking device points
downwards.
Mounting the filter
Figure 2.
Place the house extraction fan on top of the L strip so that
it is level and fasten the fan on the top cabinet frames with
four screws. It is vital that the house extraction fan is both
vertically and horizontally level. The front panel of the house
extraction fan must be at the same depth as the outer surface
of the top cabinet doors.
Figure 3.
If the highest possible mounting height is used, saw o
diagonal pieces measuring at least 20x50 mm from the spice
cabinet frame.

height is used.
PLEASE NOTE!
The minimum distance of the bottom edge of the house
extraction fan to an electric cooker is 426 mm, and to a
gas cooker 650 mm.

PLEASE NOTE!
• The house extract fan must not be connected to a flue
that is used for removing combustion gases (e.g. from a
wood- or gas-burning fireplace, cooker, or stove).
• Regulations on leading extraction air outdoors must be
observed.

Setting the ventilation profile
As the default factory setting, TTC hoods have the following
fan control voltages:
Away: 2.5 VDC | At home: 5.0 VDC | Boost: 10.0 VDC
To adjust the control voltage:
Close the damper, turn o the lights, and select
the At home ventilation profile.
Press the settings button for roughly 3 seconds until the
setting mode signal light starts to flash. The signal light will
flash in a series of five flashes to indicate that the 5 VDC
control voltage is set.
Press the ventilation profile button. The signal light will flash
in a series of five normal + one quick flashes (5.5 VDC).
Press the ventilation profile button. The signal light will flash
in a series of six flashes (6.0 VDC).
Press the ventilation profile button. The signal light will flash
in a series of six normal + one quick flashes (6.5 VDC).
Keep on pressing until you reach the maximum voltage of 10
VDC. Next, press the ventilation profile button, which sets
the control voltage at 2.5 VDC. After this, the voltage will
increase by 0.5 VDC at a time.
Save the selected control voltage by pressing the settings
button until the signal lights flash. Saving the fan speed of the
At home profile also adjusts and saves the fan speed of the
Away and Boost profiles.
The eciency of the Away and Boost profiles can also be
adjusted separately. In this case, adjusting only aects the
profile that is selected. The profile that is to be adjusted
needs to be selected when moving to the setting mode.
Alternatively, the control voltage
can be controlled using a general
meter. For that purpose, there are
probes at the bottom of the filter
enclosure (see figure).

Measuring and adjusting
performance values
Standard ventilation
The volume flow rate of the air inside the
house extraction fan is measured with
the damper closed and, where required,
adjusted based on the static pressure
loss and the performance scheme of the
house extraction fan.
• Measure the static pressure loss from
the hole in the damper using the
measuring tube found in the accessory bag (see figure).
• Determine the volume flow rate from the per formance 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 house ex traction fan.
Boost ventilation
The volume flow rate of the air inside
the house extraction fan is measured
with the damper open based on
the static pressure loss and the
performance scheme.
• Measure the static pressure loss
of the house extraction fan. The
measuring point must be located
2 times the duct diameter above
the outlet collar of the house
extraction fan (see figure).
• Determine the volume air flow based on the measured pressure
and the performance scheme (with the damper open).
