Selection of fan speedFan speed is selected by using a separate speed selector.Speed selectorThe speed selector can be used to select speeds 1, 2, 3 and 4:1. Use during absence. When the dwelling is empty, ventilation can temporarily be

diminished.2-3. Normal use. In normal conditions air needs to be replaced once in two hours.4. Boosted operation. Cooking, bathing in the sauna or bathroom, drying clothes,

using the toilet, having guests, overheat or a similar situation may cause a need forhigher than normal ventilation.

If there is a cooker hood independent of the ventilation system in the dwelling, it is notnecessary to raise the speed of VALLOX 90 SC during cooking.

Heat recovery bypassIn winter use the heat recovery cell of VALLOX 90 SC recovers heat from the air leaving thedwelling and uses it to heat the air coming from the outside.In summer use when it is warm outside, it is unnecessary to heat outdoor air. The heat recoverycell is bypassed in VALLOX 90 SC with the standard damper (A). The position of the dampercan be changed by opening the damper release (B) and then moving the damper in anotherposition. In the summer position air flow through the cell is prevented, and heat recovery bypassis activated.

Air filteringVALLOX 90 SC features coarse filtering of both extract and supply air before the fans. Thesupply air side includes a G4 class coarse filter (C) and the extract air side a G4 class coarsefilter (D). The unit can also be equipped with a F7 fine filter (E), which captures fine dust andpollen as well dust not seen to the eye. The filters need to be in place in the unit wheneverventilation is in operation.

DefrostingWater condensing from extract air may freeze in the heat recovery cell. Freezing can beprevented by stopping the supply air fan, or the unit can be equipped with a preheating resistor,which is switched on as needed.

Stopping the supply air fanThe defrost thermostat T1 stops the supply air fan whenever the temperature of extract air isbelow +5 °C after the cell. The fan restarts when temperature has risen by circa three degrees,i.e. to 8 °C. The limit of the thermostat (F) can be adjusted at the back of the heat recovery cell.If the unit includes a preheating radiator (G), the supply air fan cannot be stopped.

Outdoor preheatingThe unit can have been equipped with a preheating radiator at the factory. If that is the case,the defrost thermostat T1 switches the preheating radiator on whenever the temperature ofextract air goes below +5°C after the cell. The preheating radiator is switched off whentemperature has risen by circa three degrees to +8°C. The preheating radiator heats outdoorair before the heat recovery cell and prevents it from freezing. In very cold temperatures thepreheating radiator is not enough to heat maximum air flow to a sufficient degree (in atemperature of minus 30 degrees, maximum air flow is 30 dm3/s, which corresponds to speed2). The limit of the thermostat can be adjusted at the back of the heat recovery cell.

DESCRIPTION OF OPERATION

Control of operationPower supply to the unit can be controlled with the 0/1 switchin the distribution panel if needed. After starting, the unit operatesat the power selected on the fan speed control switch. There isalso a safety switch SS inside the unit. It stops power supply whenthe maintenance door of the unit is opened.

Fan speed adjustmentCam switchThe SF and EF fans of the unit are controlled, depending onoperating conditions, with a separate 4-step SC cam switchlocated in the ventilation zone.

Voltage signal controlThe fan power of the unit can be controlled steplessly with voltagesignal 0...10 VDC. With a voltage signal lower than 1.5 VDCthe fans stop.

Heat recovery bypassSummer-time bypass (H) of the heat recovery cell HR is donemanually by turning the HR damper in the bypass position for thesummer.

Heat recovery defrostingThe defrost thermostat TS1 of the HR cell stops the supply air fanSF, preventing the HR cell from freezing. The fan starts automaticallyas soon as the risk of freezing has passed. The operating point ofthe defrost thermostat cannot be changed, the factory setting is+5°C.The unit can alternatively be equipped with preheating radiatorLP1, controlled by antifreeze thermostat TS1. When there is a riskof frosting, preheating radiator LP1 starts to heat air coming fromoutside to the unit, thereby preventing the HR cell from freezing.The tubular preheating resistor is connected to 90°C (resetting)overheat protection and 130°C (not automatically resetting) overheatprotection.Note! The preheating radiator can be scalding hot, especially in winter.

InstallationVALLOX 90 SC has to be mounted in a place wheretemperature does not fall below +10 ˚C. Without protectivecasing, the unit must be located in a place with no acousticdisturbance: storerooms, technical rooms etc.

Wall mountingVALLOX 90 SC is mounted on the wall with a fixing plateas shown in the adjacent figure.Wall constructionWhen fixing the unit, take the wall structure into account.Because of sound conduction, avoid mounting the unit ona hollow, echoing dividing wall and on a bedroom wall; or,if you do, prevent sound conduction.

Wall mounting plate

Condensing waterThe delivery includes a water seal. With a pipe connected to the water seal,water condensing from extract air can be led to a floor drain (not straightto the drain).The pipe must not rise after the water seal. The unit has to be mounted levelwith the horizontal in order to ensure that condensing water can get out ofthe unit.

Ceiling mounting/ceiling mounting plateFastening of ceiling mounting plate to ceilingThe ceiling mounting plate is mounted straight, and it has to befastened so that there is a space of circa 6 mm between the backedge of the ceiling mounting plate and the wall (Figure 1).Theventilation unit then becomes attached to the back wall.Minimum distance between the lower edge of the ceiling mountingplate and the ceiling of the room is 14 mm. With this distance,there will be a vent of circa 2 mm between the upper edge of themounted unit and the ceiling.The ceiling mounting plate is fixed to the ceiling with M8 threadbars. After the thread bars have been fastened to the ceiling, firstturn the nuts into the thread bars and lift the ceiling mounting platein place. Then push a rubber damper and washer to each threadbar, all the way into the cup of the plate, and turn the nut.Shorten the lower ends of the thread bars so that they will be atno more than 25 mm from the lower surface of the ceiling mountingplate. NOTE! Shortening the thread bars can only be done beforemounting the ceiling mounting plate. The maximum length of athread bar from the lower surface of the ceiling is the spacebetween the lower surface of the ceiling and the lower surface ofthe ceiling mounting plate + 25 mm.

LOCKING WINGS

Mounting of ventilation unit to ceiling mounting plateBefore lifting the unit to the ceiling mounting plate, detach the following items from the unit(Figure 2):1. Thermostat knob (SC unit)2. Front panel (leave it hanging from the measurement hoses)Put the cables of the connection box into the slot in the upper part of the side plate and pullthe connection box next to the unit so that the cables remain in the slot. Make sure that theduct outlets for the unit’s extract air duct and for the duct coming from the outside to the unitare equipped with condensing water insulation. Lift the unit in place to the ceiling mountingplate till both locking wings lock to the outer edge of the side plate of the unit. Do a visualcheck of the tightness of the duct outlets and of the correct moving of the measurement hosesand electric cables. Fasten the front panel and the knob of the thermostat (SC unit) back inplace.
