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.

2.4 For Necessary Removal of Door
The door can be removed when it is open between 40º and 105º (see Fig. 9). If there is limited space in front of the unit, the lock screw under the door can be temporarily unscrewed (see Fig. 10), as well as the end studs if these are installed (see Fig. 6). Then the door can be pushed out sideways (see Fig. 11).

3 Cleaning and Maintenance
CAUTION! Before opening the door: switch off
the heat, let the fans continue for three minutes to remove hot air, disconnect power from the
unit and wait 2 minutes before opening the doors.
3.1 Fans
The fans must be cleaned a minimum of once a year. Clean the fan blades with detergent (for example methylated spirit) on a cloth and compressed air if possible. NB! Do not use water.
To take out the fans:
1. Loosen the screw on the fan door (see Fig. 12).
2. Pull out the electric quick-release contact for the motor (see Fig. 13).
3. The fan can then be carefully pulled out of the unit (see Fig. 14).
4. Loosen the screws and remove the fan cover to access the fan blades.

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.
Fig. 16
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
NB! When inserting the filter cartridge into its slot, push it properly to prevent air leakage.
