6. Installation preparation

Installation in windows WARNING Danger of cuts caused by sharp glass edges and glass breakage. Damage to the window pane from material stress. If necessary, extract the window pane and putty it back in place without stress. NOTICE Functional impairment and unit damage if installed on an uneven substrate. Make sure there is a level seating in the area of the window pane rings [7] and [10].

CAUTION Danger of short-circuits with sloping installation position through the build-up of condensation inside the housing. Only install the unit vertically, with the cable feed from above. Decide on the installation position. Maintain sufficient distance (min. 50 mm) from the window frame or wall/ceiling. Allow enough space for a correct cable feed and the opening area of the window. Get an expert to make the window cut-out – diameter 360 mm.

Lay the power cable.

Installation in walls and wooden panels Make the same preparations for the installation in walls and wooden panels as described under Installation in windows.

Dismantling internal housing with connecting flange, see Figure A, bottom left. Loosen both catches [13] with a screwdriver. Hold on to the internal housing, slightly angle the connecting flange and disconnect it from both locking hooks [3.1]. Pull the connection terminal plug [12] off. Remove the testing cables from the connection terminal socket [9]. These are no longer required.

Installation in windows NOTICE Faulty operation and unit damage caused by a rubbing impeller [14] with incorrect installation. Do not install the internal housing twisted or crimped. The internal housing [1] should only be installed indoors. Outdoor installation of the internal housing [1] is not permitted. Press the external grille [8] and the connecting flange against the window pane from outside and inside respectively.

Line the external grille and connecting flange up horizontally and bolt them together with the M5 x 25 bolts supplied [2]. The ball [11] can be used to help if unlatched first.

CAUTION Danger of injury through glass breakage if the bolts are over-tightened. Tighten the bolts carefully and do not over-tighten them. Make sure you have enough sealant, e.g. silicone in the case of special, e.g. corrugated glass. Notes ● Make sure there are no leaks at the window pane rings [7] and [10]. ● In the case of a window pane that is > 8 mm thick, replace the supplied bolts [2] with other suitable ones, of your own choosing.

Installation in walls and wooden panels Drill through the 4 housing domes [8.1] on the external grille – diameter 5.5 mm. Install the external grille and connecting flange as described before. Mark additional drill holes on the wall through the housing domes [8.1]. Loosen the mountings a little and turn the external grille with the connecting flange in the wall breakthrough by approx. 45°. Drill through the wall (4 holes).

Line up the external grille with the connecting flange again and bolt them together as described before. Additionally, the external grille is fixed to the connecting flange through the 4 drilled holes. Make sure that suitable bolts and nuts are available on site.

GB14 Electrical connection DANGER Danger to life from electric shock Switch the mains fuse off. CAUTION Unit damage in the case of short-circuits Cut off and insulate any unnecessary cable cores. CAUTION Danger of short-circuits through incorrect feeding of the power cable into the housing. Feed the power cable professionally through the cable grommet and make sure there is tension relief. See printed cable run.

Locate both cable grommets [5] in the connecting flange. Feed the power cable through the open cable grommet. Connect the power cable to the connection terminal socket [9] as shown in the wiring diagram on Page 25. Internal housing installation see also Figure A, bottom right

CAUTION Danger of short-circuits and unit damage with wrong polarity Make sure the polarity is correct, see labels A and B. NOTICE Damage to the contact holder caused by tearing or pulling on the plug cable Always hold the internal housing near the connecting flange to avoid pulling tension at plug connection.

Plug the connection terminal plug [12] on to the connection terminal socket [9]. Push the internal housing parallel onto the connecting flange as shown bottom right in Figure A. The internal housing must clip into the upper locking hooks [3.1]. Don’t trap the cables. Close both catches [13] with a screwdriver. Switch the mains fuse on. Carry out a function test.

EV 31 Switch the unit on using the switch, e.g. speed controller ST… The internal shutter opens automatically. The fan unit runs and extracts air from the room. Switch the unit off with the switch. The internal shutter closes. The fan unit switches off.

EVR 31 Switch the unit on using the switch, e.g. reversing switch STW… The internal shutter opens automatically. The fan unit runs and ventilates or extracts air from the room. Switch the unit off with the switch. The internal shutter closes. The fan unit switches off.

EVH 31 NOTICE Unit damage by jerky pulling at the pull-cord Don’t pull the pull-cord in a jerky way.

Switch the unit on by pulling the pull-cord angled towards the front. The internal shutter opens mechanically. The fan unit runs and extracts air from the room. Switch the unit off by pulling the pull-cord angled towards the window or wall and then return it to its base position. . The internal shutter closes mechanically. The fan unit switches off.

The unit is maintenance-free. With fans in swivel windows Check the connection cable regularly for signs of damage at the transfer point from the window sash to the window frame. If the cable is damaged, have it replaced by a trained electrician.

DANGER Danger to life. Unit is powered

Switch the mains fuse off. Do not remove the internal housing for cleaning. Do not flood the unit with liquid. Clean the unit with a damp cloth.

see also Figure A, bottom left DANGER Danger to life from electric shock Switch the mains fuse off. Open both catches [13]. Swing the internal housing up slightly and remove it. Disconnect the electrics. Remove the connecting flange and external grille. GB16

12. Fault rectification

● Call on the services of a trained electrician any time there is a fault. ● Repairs should only be carried out by a trained electrician.

DANGER Danger to life. Unit is powered

Switch the mains fuse off. Fault Countermeasure Unit doesn’t run. Thermal overload protection of the motor switches unit off and back on again after cooling down. Localise the cause of the fault and rectify it. Tab. 1: Fault rectification

When ordering spare parts, always quote the print number 0185.0853.0007 from these instructions, the rating plate number “X” and the corresponding item number.

Not in domestic waste. The unit contains in part material that can be recycled and in part substances that should not end up as domestic waste. Dispose of the unit once it has reached the end of its working life according to the regulations valid where you are.
