OPERATING INSTRUCTIONS

Fan speed adjustment

The fan speed of a Vallox ventilation unit can be controlled with a control switch (option), with a separate cooker hood (option) or directly with a 0–11,4 V voltage signal.

Speeds 1, 2, 3 and 4 can be selected at the control switch.

1. Operation during absence. When the dwelling is empty, ventilation can be reduced temporarily.

2–3. Normal operation. In normal operation, air has to be replaced once every two hours.

4. Boosted operation. Cooking, taking a sauna bath, washing, drying clothes, using the toilet, having guests or a corresponding situation may cause a need for higher ventilation than in normal operation.

Adjustment of supply air temperature and summer/winter function

The temperature of air coming to the dwelling can be adjusted between circa +10 °C and +30 °C. The midpoint of the adjustment range is circa +20 °C. When supply air temperature adjustment has been turned in the OFF position, post-heating is not active. This means that summer function is activated for the ventilation unit. The unit has a motorised summer/winter function. When the summer function is on, the heat recovery cell is bypassed as soon as outdoor air temperature has risen above +14 °C. When outdoor air temperature goes below +12 °C, the unit starts to recover heat. When supply air temperature adjustment is in the AUTO position, automatic function is activated for the unit. In this case, the setpoint for postheating is +17 °C and the heat recovery cell is bypassed automatically according to outdoor temperatures as indicated above. When the unit bypasses the heat recovery cell, in which case summer function is activated, post-heating is off.

Fireplace switch function

It is possible to connect a timer-operated switch to the unit. The switch stops the extract air fan during the time when the ﬁ replace is heated. NOTE! The starting of the extract air fan may weaken draught in the ﬁ replace! In winter, this situation may disturb the winter function of the unit. The situation will normalise in a while, after the ﬁ replace function stops.

Winter function of ventilation unit

A threshold value has been set at the factory for the freezing of the heat recovery cell. When the threshold is exceeded, the ventilation unit starts to melt the heat recovery cell by guiding outdoor air ﬂ ow to bypass the heat recovery cell.

A normal melting period takes from 15 to 45 minutes depending on the extent of ice on the heat recovery cell and on the amount of extract air ﬂ ow. The unit has been optimised to operate on the factory settings in normal operation in dwellings and detached houses. The winter function parameters can be adjusted for extreme conditions, such as a swimming bath, but even then it is advisable to contact Vallox Maintenance.

Adjustment of relationship between supply and extract air

This feature may be useful when adjusting air ﬂ ows at the valves during mounting. After the valves have been adjusted, a user does not need, and must not, touch the adjustment. When needed, supply or extract air ﬂ ow can be reduced at the potentiometer.

When the potentiometer is approximately halfway, supply and extract air ﬂ ow have not been reduced. Turning the potentiometer anticlockwise reduces air ﬂ ow on the supply side, and turning it clockwise reduces air ﬂ ow on the extract side.

Maintenance reminder

The unit reminds of the need for maintenance every six months if an indicator (not standard) has been connected to the connectors of the fault signal relay. The indicator then blinks at one-second intervals. The maintenance reminder is reset when the door of the ventilation unit is opened. See the maintenance instructions for information on the necessary maintenance activities.

This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack

MAINTENANCE

Before starting maintenance operations

When you open the VALLOX TSK Multi 50/80 MC unit, the safety switch of the door (T) turns power off from the unit. In spite of that, always disconnect the plug of the VALLOX TSK Multi 50/80 MC unit before starting maintenance operations.

Filters

When the maintenance reminder gives an alarm, the cleanliness of the ﬁ lters must be checked. Outdoor air is ﬁ ltered in the unit with two kinds of ﬁ lters. A coarse ﬁ lter (A) ﬁ lters off insects, heavy pollen and other dust. An F7 class ﬁ ne ﬁ lter (B) ﬁ lters off ﬁ ne dust invisible to the eye. Extract air is ﬁ ltered with a coarse ﬁ lter (C).

By using original Vallox ﬁ lters you ensure good operation of the ventilation unit and the best ﬁ ltering result. The replacement interval of ﬁ lters depends on dust content in ambient air. It is recommended to replace fans in spring and autumn, but at least once a year.

Heat recovery cell

When you replace the ﬁ lters, you are also advised to check the cleanliness of the heat recovery (HR) cell (D) at about two-year intervals.

The G4 ﬁ lters and their supports, the sealing ledge (E) above the HR cell and the side sealing ledge (F) must be pulled off before the cell can be detached. When the sealing ledge has been removed, the HR cell can be pulled out of the unit.

Note! The laminas of the HR cell are very thin and get easily damaged. The correct way to remove the HR cell is to put your hands behind the HR cell and slowly pull it off. If the HR cell is dirty, wash it by immersing it in a solution of water with washing-up liquid. Rinse the HR cell clean with a jet of water. When water has drained from between the laminas, you can push the HR cell back in place. Finally, push the sealing ledges and ﬁ lters in place.

C A

VALLOX TSK Multi 50/80 MC ﬁ lters and heat recovery cell

The units are available as right- and left-handed models. In a right-handed (model R) model, outdoor air comes to the unit from the right side of the centre line, as shown in the instructions. In a left-handed (model L) unit, outdoor comes from the left side of the unit. The ﬁ lters, summer/winter damper and heating radiator also change places correspondingly.

E F

Detaching of HR cell

Pull the coarse ﬁ lters and their frames out of the unit. Also remove the ﬁ ne ﬁ lter if it has been used. You can then pull out the sealing ledges situated on top and on the sides of the HR cell. When the sealing ledges have been removed, the HR cell can be pulled out of the unit. Note! The laminas of the HR cell are very thin and get easily damaged.

MAINTENANCE INSTRUCTIONS

Condensing water

During the heating season, humidity of extract air condenses into condensing water. Water formation may be abundant in new buildings or if ventilation is low compared to the humidity build-up caused by the residents.

Condensing water needs to ﬂ ow out from the ventilation unit without hindrance. In carrying out maintenance, for instance in autumn before the beginning of the heating season, make sure that the condensing water outlet (L) in the bottom tank is not clogged. You can check it by pouring a little water in the tank. Clean if needed.

Do not let water ﬂ ow into electrical devices. The unit comes with a condensing outlet (in the ﬁ gure) equipped with an airlock and an outlet without airlock that takes less space. If you use the outlet without airlock, you have to mount an airlock somewhere between the discharge pipes (the accessory bag contains the parts needed). An airlock guarantees the removal of condensing water and silencing of any sounds.
