[. . . ] Lift the unit into position and make sure that there is no direct contact between unit and building construction. The unit is produced for installation on the wall, but can alternatively be installed lying (i. If lying installation is chosen, ensure that necessary anti vibration pads under the unit. [. . . ] Note: Even if the cookerhood is connected to the unit, a separate extract louver must be installed in the kitchen. Make sure that the air stream from inlet diffusers has a free passage. Air stream from inlet diffuser mounted on the wall (where the ceiling is horisontal), must have throw length, so that the air is supplied to the room alongside the ceiling. Air supply through extract louvers will ensure an air stream with throw length, and extract louvers can therefore be used as inlet diffusers when mounted in the wall close to the ceiling. Setting of air volume For basic setting of inlet diffusers, open core of the diffuser 5-7 turns from closed position. For basic setting of extract louvers, open core of the diffuser 10 turns from closed position. For adjustment of air volumes to each separate room, setting on diffusers/louvers are to be made in accordance with calculations made during designing of the ventilation system or during commissioning of the system (special measuring equipment required). 3 Air circulation between rooms (Fig 7) To obtain a satisfactory air circulation, a small gap should exist around the doors between rooms with inlet diffusers (living rooms and bedrooms) and rooms with extract points (bathroom, WC, kitchen, laundry rooms etc. Install doors with slot in 2 the frame, doors without door sill or slots/vents in doors/wall (min. There will normally be no under pressure in the building, and therefore no risk for back draught from fireplace or chimney. Supply air duct directly to the fireplace would be the optimal solution, but 2 pcs. 16x16 cm vents could be installed for air supply to tumble dryer and kitchen ventilator (one for each). An open window will also give the required air supply to fireplace, kitchen ventilator and tumble dryer. 10) The unit (2) The VR 400 DCV/B & VR 700 DCV units are supplied with apx. The cookerhood (1) VR 400 DCV/B is designed for connection to cookerhood, designed for this use. 1 m cable and plug for 10A, 230V, single phase earthed connection and cable for potential free signal to unit. When opening the timer operated damper in the cookerhood, the fans will automatically go to maximum capacity. Install a 2 lead wire for potential free signal from cookerhood to the unit. [. . . ] Dampers Fresh air/Exhaust air Damper motors for fresh air intake and exhaust air (operation voltage 230V AC, type spring return) are controlled by “NO”-contacts on main PCB (PCU-EC) in unit, terminals marked “Interlock”/“NO” and “COM” respectively. The purpose of the dampers is to prevent cold air to enter the building when unit has stopped, for instance during night operation. The dampers will also close if return water temperature from the battery is below alarm limit set point for the frost protection sensor (FPS, 7-12oC). [. . . ]
