9.4 WALL MOUNTING
9.4.1 Hole preparation
Prepare a through hole in the wall with a diameter of 110 mm for KERS 25, inclined outwards by no more than 2°.
9.4.2 Telescopic duct insertion
When several KERS recovery units are installed in series with each other (see specific chapter), it is necessary to
provide passages for the connection cables between one KERS and the other, as well as for the power supply
cable.
Install the telescopic tube inside the drilled hole, so that the smaller diameter faces the inside of the room. The
telescopic tube must be flush with the internal wall and must protrude from the external wall by 10 mm. Keep an
outward inclination of approximately 2° to prevent possible condensation from flowing inward.
9.4.3 Mounting plate positioning
Connect the mounting plate: For the connection, refer to what is indicated in the drawing in chapter 4.3.
Fix the mounting plate to the wall with 4, 4x40, screws and 6x40 plugs, included in the supply.
