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.

REPLACING THE FILTERS

When the maintenance reminder becomes activated,

check the cleanliness of the filters and replace them if

A

required.

The Vallox ventilation unit has three air filters:

S

· Coarse filter for supply air filters insects, heavy pollen

C

and other relatively large foreign objects out of the

outdoor air.

B

· 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. Open the door of the Vallox ventilation unit by undoing the finger screws.
3. Lift the door off. 4. Remove the old filters (A, B, C) and discard them.
CAUTION The door is heavy.
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.

11

IMPORTANT If the power cord is damaged, the manufacturer, its service representative or other person with similar qualifications must replace it to avoid danger.
NOTE The service space in front of the ventilation unit must be at least 500 mm.
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

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”.
19

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.
