User manual SYSTEMAIR VR 700 DCV

[. . . ] VR 400 DCV/DE is only available as a left hand model. Bottom side of bracket should be 45 mm below top of unit position, when installed on the wall. Check that the anti vibration packing (2) on the mounting bracket and on the backside of the unit (3) is undamaged. Lift the unit into position and make sure that there is no direct contact between unit and building construction. [. . . ] Inlet diffuser should be mounted in the ceiling. 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. Use frames to ease the removing of diffusers for cleaning. 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 closing vents in outer wall is a good alternative. 16x16 cm vents could be installed for air supply to tumble dryer and kitchen ventilator (one for each). These should preferable be installed in the same room. 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. 1 m cable and plug for 10A, 230V, single phase earthed connection. 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.
