Table of Contents

In blocks of flats and terraced houses, the maintenance of the unit is taken

care of by a property maintenance company or the user, depending on the

contract.

Before starting maintenance activities, stop the machine either at the ON/OFF switch or by removing the

fuse from the fuse panel of the dwelling. The safety switch also turns the unit off when the door is opened.

FILTERS

Outdoor air is filtered in the unit with two types of filters. A G3 class coarse filter(A) filters

off insects, heavy pollen and other dust. A F7 class fine filter (B) filtersoff fine, invisible dust.

Extract air is filtered with similar G3 class filters as outsideair.

Clean the coarse filter (A) when needed for example by washing them 2 to 4 times a year

(and more often if needed). Wash a coarse filter with +25...30 °C warm water and washing-

up liquid, pressing it smoothly. Do not handle the filters with force.When washing is done

properly, filters stand cleaning 4...5 times. In otherwords, you have to replace them at least every

two years or when needed.

The fine filter (B) is not washable. Clean it at the same time as the coarse filters,using the

brush nozzle of a vacuum cleaner. When cleaning, be careful no tobreak filter material. To

ensure good supply air quality, replace the filter from every six months toyear (more often if needed)

depending on local air quality. It is recommended to replace filters in autumn. This way the

filters stay cleaner through the winter and can effectivelyfilter off dust in the following spring.

In connection with the cleaning of the filters, it is also advisable to check the cleanliness of

theheat recovery cell (C) every two years or so. Grab the ears at the ends of the cell and

pull thecell out of the unit. If the cell is contaminated, soak it in a solution of water and

washing-upliquid. Rinse the cell clean with a jet of water. When all the water has drained

from betweenthe laminas, push the cell back so that the sealings next to the sliding surfaces

are in place andthe "up" sticker at the end of the cell points to the corner next to the upper

support.

In addition, check in autumn and spring the position of the summer / winter damper and

theleaving of condensing water from the unit as well as the position of the post-heating

radiator thermostat.

Filter guard Vallox 75/95 (option)

VALLOX 75/95 can be equipped with an optional filter guard. The filter guard indicator

lights up at speeds 3 and 4 when the filters are clean; this is normal and does not call for

any maintenance activities. If the indicator does not light up at speed 4, the pressure over

the finefilter differs from the factory setting. When needed, an expert may change the setpoint.

If the filter guard symbol already lights up at fan speed 1 or 2, the filters need cleaning. If they are clean,

the lighting up may be caused by a clogged up dense mosquito net installed against mounting

instructions in the external grille or by the closing of the supply air valves in the rooms.
