INSTALLATION

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. The minimum distance between the top of the unit and the finished ceiling surface is 30 mm. Note that during mounting the unit rises 10 mm higher than the final height. Mount the ventilation unit onto the wall with a mounting plate (optional), as shown in the figures below. Make sure that the unit is horizontally level after mounting.
MOUNTING ON THE CEILING
Vallox 096 MV and Vallox 110 MV can be equipped with an optional ceiling mount plate. To attach the ceiling mounting plate: · On rafter frames or other frame structure with M8 thread bars so
that they withstand the weight of the unit. · Ensure that the installation plate is horizontally level, as this
determines the position of the unit. · The top edge of the white covering strip of the ceiling mounting
plate can be installed against the ceiling. Alternatively, a concealed mounting method can be used, in which case the ceiling can be 20 mm below the top of the white covering strip. Insulate the ducts against condensation also between the unit and the ceiling mounting plate.
Mounting the ceiling mounting plate
1. Fasten the thread bars on the rafter frames or other frame structure, and screw the nuts onto the bars.
2. Lift the ceiling mounting plate in place. 3. Push a rubber damper and a washer onto each thread bar, and ensure
that they touch the bottom of the cups of the plate (Vallox 096 MV). 4. Turn the nuts to make sure that the unit is horizontally level. 5. Shorten the lower ends of the thread bars so that they will be at no
more than 10 mm from the lower surface of the ceiling mounting plate. CAUTION The ventilation unit is very heavy. Do not perform this procedure alone.
7

NOTE When installing the unit, reserve a sufficient space in front of the unit for servicing purposes. Mount the ventilation unit in a place where the temperature does not fall below +10°C. Vallox 096 MV: The service space in front of the unit must be at least 400 mm. Vallox 110 MV: The service space in front of the unit must be at least 450 mm.

MAINTENANCE

MAINTENANCE
BEFORE BEGINNING MAINTENANCE WORK
The safety switch (S) automatically turns off the power when the door of the unit is opened.
WARNING Always disconnect the power plug before starting the ventilation unit maintenance. There are two unit models, left- (L) and right-handed (R). The figure shows the right-handed model.
CHANGING THE FILTERS
When the maintenance reminder becomes activated, check the cleanliness of the filters and replace them if required. The Vallox ventilation unit has three air filters: · Coarse filter for supply air filters insects, heavy pollen
and other relatively large foreign objects out of the outdoor air. · Fine filter for supply air filters microscopic pollen and dust particles out of the supply air. · Coarse filter for extract air filters the extract air and keeps the heat recovery cell clean.
The filter replacement interval depends on the ambient particle concentration. It is recommended that the filters be replaced every spring and autumn, or at the very least once a year.
To replace the filters: 1. Disconnect the ventilation unit from the mains
electricity supply. 2. Lift the latch to open the door of the Vallox ventilation
unit. 3. Lift the door off.
CAUTION The door is heavy. 4. Remove the old filters (A, B, C) and discard them. 5. Install the new filters (A, B, C). 6. Close the door of the unit. Ensure that the safety switch catch of the door is touching the safety switch, allowing the unit to be turned on. 7. Plug the ventilation unit back into the mains.
The filters have now been successfully replaced.
14

IMPORTANT If the power cord is damaged, the manufacturer, its service representative or other person with similar qualifications must replace it to avoid danger.
TIP Using original Vallox filters ensures that the ventilation unit remains in top condition, giving the best results. To select and order filter packages, please go to: filters.vallox.com
NOTE Vallox 096 MV: The service space in front of the unit must be at least 400 mm. Vallox 110 MV: The service space in front of the unit must be at least 450 mm. Vallox 145 MV: The service space in front of the unit must be at least 550 mm.

CLEANING THE HEAT RECOVERY CELL
Check that the heat recovery cell is clean roughly once a year, or whenever the filters are being replaced. Clean by washing as required.
To check and clean the heat recovery cell: 1. Disconnect the ventilation unit from the mains electricity
supply. 2. Open the Vallox ventilation unit door by first lifting the latch
fully up and then lowering it back a little way. 3. Lift the door off.
CAUTION The door is heavy. 4. Remove the filters (A, B, C). 5. Remove the sealing strip (E) above the cell in the direction of the arrow. 6. Lift and pull the cell (D) out of the unit.
IMPORTANT Handle the cell carefully! For example, do not lift the cell by the layers. The cell layers are very thin and easily damaged. 7. 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. 8. Rinse the cell clean with a water spray. Do not use a highpressure cleaner. 9. When all the water has drained from between the layers, reassemble the ventilation unit in the reverse order. 10. When reassembling Vallox 096 MV, check that the sealing strip below the cell is pressed against the bottom of the unit. 11. Close the door. Ensure that the safety switch catch of the door is touching the safety switch. 12. Plug the ventilation unit back into the mains.
The heat recovery cell has now been checked and cleaned.
CONDENSING WATER
In the heating season, the extract air humidity condenses to water. In new buildings, condensation runoff 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.
15

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.

MAINTENANCE

CLEANING THE FANS
Check the cleanliness of the fans when servicing the filters and the heat recovery cell. Clean the fans as required. You can clean the fan blades with compressed air (wear protective goggles) or by brushing them gently. Do not remove or move the fan blade balancing weights.
Cleaning the supply air fan
To clean the supply air fan: 1. Disconnect the ventilation unit from the mains electricity
supply. 2. Lift the latch to open the door of the Vallox ventilation unit. 3. Lift the door off.
CAUTION The door is heavy.
4. Remove the extract air filter (C), the cell top bracket (E) and the heat recovery cell (D). See chapters “Replacing the filters” and “Cleaning the heat recovery cell”.
5. Pull out the temperature sensor (figure 1) located at the top of the extract air duct (G). Remove the stopper screw (I) at the bottom of the duct. The extract air duct now comes out by turning and pushing it downwards simultaneously (figure 2).
6. Remove the temperature sensor from the resistor support (figure 4).
7. Remove the additional and post-heating resistor support, which is attached by two wing nuts (Vallox 110 MV and Vallox 145 MV) or screws (Vallox 096 MV) from below (figure 5).

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. Do not remove or move the fan blade balancing weights.

TECHNICAL SPECIFICATIONS

DUCT RADIATOR OPERATION
Always follow first and foremost the connection diagram provided by the HVAC designer or heat pump manufacturer. Also read the duct radiator manual.
The accompanying figure shows an example of the arrangement for connecting the heating/cooling radiator unit to the heat collection circuit.
Connect the radiator output pipe to the heat collection circuit return pipe. Direct the fluid returning from the radiator unit to the heat collection circuit return pipe. If you know that there is a large loss of internal pressure inside the heat pump, the heat pump should be bypassed. If this is done, the fluid circuit will come into operation when the heat pump comes to a halt. When this happens the pressure loss in the one-way bypass valve Y2 must be lower than the pressure loss in the heat pump.
Heating: The pump starts when the outdoor air temperature drops below the winter limit value set at the factory (-5 °C).
Cooling The supply air setpoint value for the active mode (for example, At home) controls the pump start-up. The pump starts when the supply air setting is below the temperature of the supply air that is blown into the apartment.
The duct radiator can be installed in both the supply air duct and the outdoor air duct. If the radiator is installed in the outdoor air duct, it can be used for both preheating and cooling. If the radiator is installed in the supply air duct, it can be used for heating or for cooling only.
The duct radiator can be set to function either automatically or manually.
· Automatic – In summer, the supply air temperature will be maintained at the level specified in the temperature setting. In winter, the duct radiator will turn on, when the outdoor temperature falls below the winter setting.
· Manual – In summer, the duct radiator will turn on, when the outdoor temperature rises above the summer setting. In winter, the duct radiator will turn on, when the outdoor temperature falls below the winter setting.
To prevent the risk of condensation in the supply air duct, you can set the adjustment of the supply air limit to automatic or manual.
· Automatic – The supply air limit is adjusted automatically based on the dew point of the extract air. When the supply air temperature falls too low, the duct radiator will turn off.
· Manual – The supply air limit can be set manually. When the supply air temperature falls down to the set value, the duct radiator will turn off.
If an external sensor is in use, it is selected from the settings of the external sensor whether it is used to control the outdoor air duct radiator or the supply air duct radiator. The temperature of the external sensor can be read from the service menu: menu > service menu > unit information page 5 “External sensor”.
26

NOTE: If the duct radiator is used in the supply air duct, it can only be used for cooling.
NOTE: When used to control the outdoor air duct radiator, the external NTC sensor is installed in the outdoor air duct before the radiator. When used to control the supply air duct radiator, the external NTC sensor is installed after the radiator.
NOTE: When selecting the relay (C), take account of the maximum allowed combined power supply (6W) of the circuit board in the external MV electrical box, if the relay power supply comes from the circuit board’s +24V connector.
NOTE: Due to the risk of humidity damage, in a duct that has not been insulated for condensation the supply air temperature must not fall below +16 … 20 °C.
