7. Installation preparations
Notes
● Refer to Chapter 15 for housing dimensions.
● Select the installation location such that the service
door can be opened wide, so that you can get to the
impeller and clean the inside of the ventilation box.
● The ventilation box is supplied for an installation
position with the exhaust socket directed upwards.
● If the ventilation box is to be turned through 90° for
installation, the hinges and the door handle on the
service door must be adjusted. The service door is
not turned for this purpose. It stays in its original
position.
● A suitable holder must be used for wall or ceiling
mounting, in order to be able to install the ventilation
box as a floor-mounted unit. Ceiling, wall and holder
must have sufficient load-bearing capacity for the
total weight. Suitable mounting material is to be
supplied by the customer.
● If an increased build-up of condensation is expected,
the condensation run-off must be ensured. To do
this, connect a drain tube with siphon to the
condensation discharge outlet [14].
Installation with condensation run - off is only
permitted with a device installation position
where the exhaust socket is directed upwards.
Only in this case is the discharge outlet [14] at the
bottom and the secure run-off of condensation is
guaranteed.
8. Assembly
8.1 Conversion for 90° installation position
● When the ventilation box is turned through 90°, the
door hinges are installed opposite the exhaust
socket.
● The door handle is repositioned.

Carefully lay the device on its back (intake sockets).

Reposition the screw/washer [6] (depending on the
installation position, see arrow above).

Remove both door hinges [12].
Do not turn the service door. It stays in its
original position.

Mount both door hinges on the underside of the
device and the service door (→ circular cut -out) and
screw securely into place.

Remove the door handle [2] and mount it at the side
installation position (→ figure above).

Close off the condensate discharge outlet [14] with
sealing material.
8.2 Device installation, exhaust socket on the
top

Carefully lay the device on its back (intake sockets).

Screw both mounting tracks [2] at the holders [5] to
the housing (Pos. A). Use the supplied screws and
washers [5.1].

Screw the 4 vibration dampers [1] to the mounting
tracks with the supplied cap nuts.

Install the device and locate it horizontally at the
installation location. Make sure that it is securely
located on the vibration dampers.

Provide spacers to compensate for any unevenness
in the floor.

Connect ventilation ducts to the ventilation box on
the exhaust air and outgoing air sides. Use an ELR
flexible fixing cuff on both the suction and pressured
air side, to avoid the transmission of vibrations to the
duct system.
