4.2. Fans and post-heating radiatorThe supply and extract air fans (D and E) have been fastened with rubbercollars (F). When removing the fans for maintenance, remove the one-waydampers (L) from the VKL model, open the ear (K) attached to the fan, bentover the rubber collar. Then lift the rubber collar away and turn the fan awayfrom above the lower support (M) made of rubber. Then take the electricalconnector (G) off from behind the fan.Clean the fan blades with compressed air.If you use water when cleaning the unit or its parts, do not let water enter the electric parts.For cleaning the post-heating radiator (J), remove the filters and the heatrecovery cell. Clean the post-heating radiator while it is in place in the uniteither by vacuuming it or blowing it with compressed air. The radiator can beeither electric or water circulated. If needed, you can remove the electricradiator for maintenance by removing the electrical connector (H) as well asthe two tightening-up screws (I) and the adhesive or screw fixing the supportagainst the bottom reservoir.4.2.1. Detaching and attaching of one-way damper.Detaching and attaching of self-actuated one-way damper (vacuum damper):A Put the hook on the rim of the damper (Y) under the side edge of thefastening collar (K) of the fan (F). Then push the damper downwards sothat the guide edges of the valve go inside the rubber collar.B Push the other side of the collar with a finger.C Put the hook on the other side edge of the damper below the edge of thecollar.To detach the damper take the same steps in the opposite order.Self-actuated one-way dampers are only used in VKL model units. Observethe position of the damper so that it can also operate on the F7 filter side.4.3. Filter guardDIGIT SE can be equipped with an optional filter guard. The filter guard symbol ( ) normallylights up in the main display at speeds 7 and 8, when the filters are clean, and this doesnot cause any service activities. If the symbol does not light up at speed 8, the pressure inthe ventilation ductwork of the building differs from the factory setting. In that case, adjustthe filter guard setpoint lower in the inside of the unit (see Section 2.14). If the filter guardsymbol lights up at fan speed 4 or 5, the filters need cleaning. If they are clean, the lightingup may be caused by too dense a mosquito net installed in the external grille or by theclosing of the supply air valves in the rooms. If, after checking these things, the symbolcontinues to light up at small speeds, adjust the setpoint greater.4.4. Condensing waterDuring the heating season, the humidity in extract air condenses as condensing water. Waterformation may be abundant in new buildings or if ventilation is scarce in terms of moistureproduction by the inhabitants. The condensing water must exit the unit without hindrance.In connection with maintenance operations, for example in the autumn before the start ofthe heating season, make sure that the condensing water joint (L) in the bottom reservoir isnot clogged. You can check this by pouring a little water in the reservoir. Clean if needed.Do not let any water enter the electrical devices.VALLOX DIGIT SE/SE VKL14MAINTENANCE INSTRUCTIONS© VALLOX • We reserve the right to make changes without prior notification.FKYFKYFKYFKYA B CFPLEGDGHI JMMLFKKQ
