VALLOX X-Line PTXP MC Ventilation Units User Manual
The Vallox X-Line PTXP MC control hood is suited to controlling SC or MC ventilation units.
The cooker hood is designed to be used above the cooker top, as a general extraction valve in the kitchen, and as a ventilation system control panel.
VENTILATION CONTROL
Apartment-specific ventilation units allow residents to adjust the ventilation efficiency. Ventilation is controlled based on the need e.g. through the cooker hood, ventilation control panel, or a separate control centre.
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.
-
Away mode (position 1).
The ventilation efficiency can be temporarily reduced when the apartment is unoccupied. -
Normal mode (position 2 or 3)
Ventilation must be continuous, i.e. the air inside the building must be replaced at least once every two hours. -
Boost mode (positions 3-4)
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. This is done by boosting the ventilation either in general or space-specifically. For example, the damper of the cooker hood is kept open during cooking but is closed or in the minimum position at other times.
USING THE UNIT
Front panel
Position of the damper
When turned to the left, the damper is in the closed position: In normal
circumstances, the damper must be closed,
which boosts the extract air flow from other premises.
When turned to the right, the damper is in the open position
used when the extract air flow needs to be boosted, e.g., in the following
situations:
- when the cooker top or the oven is used for cooking
- when the load in the kitchen is exceptional e.g. due to the use of strong detergents or the presence of a large number of people.

WARNING
The unit is not intended for use by children under 8 or by persons with
reduced sensory, physical or mental capabilities, or whose lack of knowledge
and experience do not ensure safe operation of the unit. Such persons can use
the unit under supervision, or by following the instructions of someone who is
responsible for their safety. Do not let children play with the unit or to
clean or maintain it without supervision.
WARNING
If the ventilation of the apartment is turned off, the entry of fresh
replacement air into the apartment and the extraction of used air from the
apartment are prevented. Impurities, such as carbon dioxide, humidity, smells,
formaldehyde, dust, and radon, which come from people, structures, and the
soil will quickly contaminate the room air and are harmful to the health of
people. Excessive humidity may damage the structures of the building and
result in mould and fungal growth. For this reason, building regulations
require that ventilation be turned on at all times and that its efficiency is
adjusted based on the needs of the user.
CAUTION
- Neglecting the cleaning of the grease filter can cause a fire hazard.
- The outer surfaces of the hood can become hot when the cooker or the oven is turned on.
- Flaming is forbidden underneath the cooker hood.
- Always follow the instructions provided on adjusting the efficiency of ventilation.
- Enable a sufficient supply air flow into the room if the cooker hood and nonelectric devices are used simultaneously
MAINTENANCE
Keep the cooker hood clean. Wipe outer surfaces regularly with water containing a small amount of a mild detergent. Clean off 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 by hand or in a dishwasher at least 1-2 times a month.
Removing and mounting the grease filter
-
Open the quick connectors of the bottom plate of the cooker hood by turning (Figure 1).
-
Turn the bottom plate down.
-
Remove the grease filter from its holder (Figure 2).
Replacing the lamp
-
Remove the protective glass of the lamp by moving it to the left (Figure 3).
-
Remove the lamp by pulling it to the left (Figure 4).
-
Lamp type: G23 LED.
INSTALLATION
Use the mounting accessories included in the package to fasten the cooker hood in place.
- Shorten the extract air duct to be connected to the hood (125 mm spiral duct) to the correct length.
- Where required, install a Vallox cover strip, for instance, (2142400 cover strip 500 or 2142500 cover strip 600) to cover the opening in the rear wall.
- Lift the hood so that it is in contact with the duct.
- Fasten the cooker hood with the mounting brackets or by other means, so that the hood is firmly in place and cannot move (figures 1, 2 and
- The mounting screws included in the accessory bag are suited to walls made of wood, chipboard, cement or stone. Use appropriate mounting devices for other materials.
- Check the tightness of the extract air duct system.
- Plug the cooker hood into the mains. Ensure that the plug can be unplugged, where required.
Signal light
The signal light shown in Figure 1 (A) is on when the MC ventilation unit
controlled by the hood is on. Signal light flashing at one second intervals
indicates that it is time for maintenance of the ventilation unit. This
reminder is shown every six months. The service reminder is set off when the
door of the ventilation unit is opened. Other reasons for the flashing of the
signal light indicating failure are described in the manual of the ventilation
unit.
The signal light is not in use if the hood is used for controlling roof fans
or some other ventilation unit, or if the signal light has not been connected
to the ventilation unit.
CAUTION
- The cooker hood 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).
- The cooker hood must not be fastened through the side panels to the cabinets.
- Fans that are controlled through the cooker hood must have an engine cover and their maximum power must not exceed 340 W.
- Regulations on leading extraction air doors must be observed.
WARNING
A G23 PL lamp will cause damage!

Performance values
Adjusting the fan speeds
A low signal voltage is coming to the control panel and, therefore, the
adjustment is made while the control panel is connected and the ventilation
unit is running.
- The adjustment is made by using the four holes found underneath the knob of the ventilation control panel (Figure 2) one speed at a time, by using the potentiometer of the speed in question.
- The set voltage can be measured from the measurement points found underneath the knob of the control panel (markings S and -) or on the terminal block underneath the black casing (markings S and -, see Figure 6) by using the DC voltage measuring of a universal meter. The adjustment range is ~2…11.2 V.
- The control voltage (air flow) increases when the potentiometer is turned to the right. The preset voltages are 2.5 V, 5 V, 7.5 V, and 10 V. Please note! Do not set the control voltage so low that the fan does not stop (approx. 1.5 V).
An example of air flow adjustment:
Standard ventilation is adjusted at speed 2.
- Set the control panel to speed 2 and measure the air flows from the valves.
- If the total air flow is too low, increase the control voltage from potentiometer 2.
- If the total air flow is too high, decrease the control voltage from potentiometer 2. Do not choke the air flow unnecessarily by using valves!
- The balance between the supply and extract air flow of the Vallox MC ventilation unit is adjusted with the potentiometer inside the unit. Do not change the supply/extract balance in connection with measurements conducted at other speeds.
- Adjust the Away air flows similarly by using speed 1 (potentiometer 1).
- Adjust the Boost air flows similarly by using speed 3 (potentiometer 3).
- Speed 4 is usually reserved for the maximum speed.
Adjustment positions of the damper
Set the ventilation control to position 1 and remove the knob by using a
screwdriver, for exampl
There are holes for adjustments and measurements underneath the knob
Measure the voltage from poles – and S, set e.g. speed 1 from potentiometer 1
Replace the knob, set the ventilation control to the next speed, and remove
the knob again.
Measure the voltage from poles – and S, set speed 2 from potentiometer 2, etc.
You may also carry out the measurement from the terminal block, at the places
indicated by the wiring diagram.
Lastly, measure the voltage of each speed from the measuring pins and record them in the measurement log. In e.g. terraced houses, the voltage measurement can be used to “copy” the measurement made in the first apartment to other similar apartments.
