6. Installation preparati on

Installation in windows

WARNING

Danger of cuts caused by sharp glass edges and glass breakage. Damage t o the window pane from mater ial stress.

 If necessary, extract the

window pane and putty it back in place without stress.

NOTICE

Functional impair ment and unit damage if inst alled on an uneven substrat e.

 Make sure there is a level

seating in the area of the window pane rings [7] and [10].

CAUTION

Danger of short-ci rcuits with sloping install ation position through the build- up of condensation in side the housing.

 Only install the unit vertically,

with the cable f eed from above.

 Decide on the installation position.

Maintain sufficient distance (min. 50 mm) from the window fr ame or wall/ceiling. Allow enough spac e for a correct cable feed and the opening area of the window.

 Get an expert t o make the window cut-out

– diameter 360 mm.

 Lay the power cable.

Installation in walls and wooden panels

 Make the same preparati ons 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 catc hes [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 pl ug [12] off.  Remove the testing cables from the

connection t erminal socket [9]. These are no longer required.

7. Installation

Installation in windows

NOTICE

Faulty operation and unit damage caused by a rubbing impeller [14] with incorrect installation.

 Do not install the internal

housing twis ted or crimped.

The internal housing [1] shoul d only be installed indoors. Outdoor installation of the internal housing [1] is not permitted.

 Press the external grille [8] and the

connecting flange against t he window pane from outside and inside respectively.

 Line the external grille and connecting

flange up horizontally and bol t them together with t he 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 overtightened.

 Tighten the bolts carefull y and

do not over-tighten them.

 Make sure you have enough sealant, e. g.

silicone in the case of special, e.g. corrugated gl ass.

Notes

● Make sure there ar e no leaks at the window pane rings [7] and [10].

● I n the case of a window pane that is > 8 mm thick, replac e the supplied bolts [2] with other suit able 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 hous ing domes [8.1] .

 Loosen the mountin gs 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 f lange again and bolt them together as des cribed before.

 Additionally, the external grille is fixed to

the connecti ng flange through t he 4 drilled holes. Make sure that suitable bolts and nuts are available on site.

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 insulat e any

unnecessary cable cores.

CAUTION

Danger of short-circuits through incorrect feeding of the power cable into the housing.

 Feed the power cable

professi onally through the cable grommet and make sure there is tension relief. See printed cable run.

 Locate both cable grommets [5] in t he

connecting f lange.

 Feed the power cable through the ope n

cable grommet.

 Connect the power c able to the connection

terminal s ocket [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 l abels A and B.

NOTICE

Damage to the contact holder caused by tearing or pulling on the plug cable

 Always hold the inter nal

housing near t he connecting flange to avoid pulling tension at plug connect ion.

 Plug the connect ion terminal pl ug [12] on to

the connecti on terminal socket [9].

 Push the internal housing parall el onto the

connecting flange as shown bott om right in Figure A.

The internal housing must clip into the upper locking h ooks [3.1]. Don’t trap the cables.

 Switch the unit off with the switch.

The internal shutter closes. The fan unit s w itches off.

EVR 31

 Switch the unit on using the switc h, 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 s w itches 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 pul l-cord

angled towards the window or wall and then return it to its base pos ition. . The internal shutter clos es mechanically. The fan unit s w itches off.

9. Maintenance

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 t he window frame.
