General installation requirements

The ComfoSpot 50 is intended exclusively for installation in an outside wall, where the side air passage openings must be
located on the inner side, vertically and with the thumb wheel for shutter adjustment on the right side.
The following requirements and precautions at the installation site must be taken into account:
WARNING
Observe accident prevention regulations
Observe the accident prevention regulations when setting up the installation site.
Secure the outside area against falling parts.
WARNING
Danger due to escaping gas or electric shock
Make sure that there are no supply lines (e.g. electricity, gas, water) in the area of the external wall opening.
Ensure that the external wall opening meets the static requirements on site.
WARNING
Risk due to electric shock
Observe the country-specific standards/regulations for compliance with the protection areas for installation in rooms
with a bathtub or shower with regard to the IP11 degree of protection applicable to the ventilation unit.
NOTE
The electronics/control unit can be damaged by static charge; which is why you must always take measures to prevent
electrostatic discharge when handling the control unit (e.g. by wearing an anti-static armband).

Installation preparations

4.2.2.1 Preparations for installing the wall mounting pipe
Prior to installing the ventilation unit, an appropriate wall mounting pipe must already be installed in the outside wall at the
designated installation location. It must be adjusted flush with the dimensions of the final wall structure.
The square wall mounting pipe, intended in particular for new buildings, should be integrated in the outside wall construction
in the course of constructing the outside wall. The round wall mounting pipe is to be inserted after drilling a core hole (
340 mm) into the drill hole of the outside wall.
NOTE
Installation of the ComfoSpot 50 requires the use of the round or square wall mounting pipe.
Observe the respective enclosed instructions on professional installation when installing the wall mounting pipe.
4.2.2.2 Preparations for installing electrical connections
The mains supply line for the power supply must be installed in the area of the bottom left side of the unit and, where
applicable, the control cable for connecting an optional external control panel, must be installed up to the area of the bottom
right side of the unit. The cable ends should protrude approx. 10 cm out of the wall surface in the respective area of the
cable entry point of the bottom cover of the interior cover.
