UNI 3 User Manual
1 Functional Description Balanced
Ventilation
1.1 Fans (M1, M2)
The fans ensure that air enters and leaves the building. These
can be individually adjusted for optimal operation. The unit
can be regulated at 3 different speeds using the operating
panel; Min, Normal and Max. See section 5.1 for more
information.
1.2 Filter (FI1, FI2)
Filters with a high filter grade (ePM1 55% F7) are used as
standard both for supply air and extract air, so that the air
which enters the building is clean. The filters also ensure that
the unit stays clean.
1.3 Heat recovery system (HR-R)
The air goes through the rotary wheel heat recovery system.
The rotor functions as a heat storage. The heat from the
extract air heats up one half of the rotor. When the heated
part comes over to the supply air side, the heat is transferred
to the supply air.
1.4 Heating element (EB1) (for UNI 3 E)
If the heat recovery system cannot raise the temperature
enough, an electrical heating element will raise the
temperature to a set level. The heating element is protected
against overheating by the thermostat (F20), which switches
off at 60°C. As an additional safety measure, the F10
thermostat switches off at 85°C. The F10 thermostat must be
reset manually by pressing the reset button (see Fig. 2).
1.5 Temperature sensors (B1, B4)
The unit has two temperature sensors as standard. Supply air
sensor B1 registers the temperature of the heating battery.
The outdoor air sensor (B4) registers the temperature of the
outdoor air.

3.2 Filter
The filters have a limited lifetime, and to preserve a
healthy indoor air quality it is important to change them
when they are dirty.
How often the filters need to be changed depends on the
degree of contamination in the air where they are installed.
In general, the filters need to be changed a minimum of once
a year, preferably in the autumn (after the pollen season). In
areas with a lot of dust and contamination, the filters should
be changed in the spring and autumn.
Dirty filters can, among other things, lead to:
• Reduced performance of the unit
• The unit becoming dirty
• Humidity damage in the bathroom
• Reduced indoor air quality
A filter subscription is recommended to ensure full benefit
from the system. The article number for a replacement filter
set is 110716.
To take out the filters:
1. Grip the handle and pull the filter cassette out (see Fig.15).
2. Push the filter out of the cassette (see Fig.16).
3. Insert a new filter.
NB! Ensure that the filter is not damaged during
installation. Use the filter’s outer edge when you
push it in. A damaged filter reduces the unit’s
effect and the air’s purity.
When changing the filter, check that the whole unit is working
normally. Use the following checklist:
• Check that the rotor is rotating (see Fig. 17).
• The unit has filters both for outdoor air and extract air.
• Check that the fans are clean.
Fig. 15
Fig. 16
Fig. 17
NB! When inserting the filter cartridge into its
slot, push it properly to prevent air leakage.

3.3 Replacing the brush strips
The brush strips become worn over time. If they do not
sit tightly against the rotary wheel-type heat exchanger,
it can be necessary to replace them (art.no. 110894).
Alternatively, they can be moved closer to the rotor, where
the aluminium profile they are mounted in has two grooves.
Do the following:
1. Pull the rotor a little way out (see Fig. 18).
2. Unplug the quick-release contact fastened to the rotor
(see Fig. 19).
3. Pull the rotor out completely.
4. Remove the screw in the centre of the aluminium profile
and pull the profile out (see Fig.20).
5. Pull the brush strips out of the groove. Move them up
from level 1 to level 2 (see Fig. 21), or replace them with
new ones if they are completely worn out.

3.4 Rotor
As the unit has high impermeability, filters installed, it is not
usually necessary to clean the rotor. If, for various reasons,
it should still be necessary, dust can be removed with a soft
brush.
Further cleaning is possible if you remove the rotor, spray it
with fat-soluble detergent and then blow it clean from the
opposite side. Distance approximately 60 mm and max.
pressure 8 bar.
Ensure that the motor is not exposed to water during
cleaning. Ensure that all seals around the rotor are intact
and tight. Ensure that there is no damage to the rotor belt,
and that the rotor rotates freely.
3.5 Tightening of rotor belt
The rotor belt can be tightened by releasing 8 screws in order
to remove the rotor side plate (See Fig. 22).
Next release the screws (one on each side) holding the rotor
motor in place (see Fig. 23). This will allow the rotor motor
to be repositioned, thus tightening the belt (see Fig. 24).
Tighten all the screws again
3.6 External Cleaning
Many kitchen surface cleaners contain chemicals that
may damage the product’s plastic components. Therefore
use a soft cloth moistened with warm water and a neutral
detergent to clean the outside of the product.
NB! Do not use abrasive cleaners or scouring
powder, as such products can damage the
surfaces. Do not use cleaners containing citric
acids or ammonia. Products that give stainless steel
an anti-fingerprint coating must not be used either.

5.1 General
The control unit consists of a touch panel with pushbuttons,
LEDs for indication and adjustment potentiometers and
switches for adjusting the ventilation unit. The control unit
communicates with the ventilation unit via a low-voltage
cable.
5.2 Increasing/reducing air supply
Use switches 1 and 2 to increase and reduce the fan speed
and thus the air flow. Different speeds depending on the
operating situation.
MIN Do not use during first year of operation, or
when the building is in use.
NORMAL Used under normal conditions. In this
setting, the air supply must be adjusted
according to current regulations.
MAX Used if there is a need for increased air
supply on account of increased occupancy
or a higher humidity level, for example
during showering or when clothes are being
dried. This setting is usually used for limited
periods of time.
The different speeds are indicated with LEDs 3, 4 and 5.
5.3 Adjusting the air supply
At NORMAL speed level, the air flow must be adjusted
according to project data. Potentiometer 9 is used for the
supply air level and potentiometer 8 for the extract air level.
The adjustment range is 20-100% of the maximum level
according to the scale of the potentiometer.
Factory settings:
MIN 50% (fixed)
NORMAL 75% (variable)
MAX 100% (fixed)
5.4 Temperature adjustment
The temperature required in the supply air can be set with
potentiometer 11. The adjustment range is 10 - 30 °C. Using
the factory settings is recommended.
If necessary, the ventilation unit’s heating can also be
switched ON/OFF with switch 10. In this case only the rotating
heat exchanger is used as a source of heat. It is best to leave
it in ON position, as the unit will then respond automatically
when there is a need for additional heating.
5.5 Filter replacement
Every six months, LED 6 lights up to remind you that it is time
to replace the air filters in the unit. See section 3 for more
information on filter replacement.
After the activity has been carried out, the
indicator must be reset. See more under the
Reset section.
5.6 Alarm
If anything unforeseen occurs with the
ventilation unit, indicator 6 lights up.
The signal given by the indicator depends on the
reason for the indication.
A permanent light indicates:
