EN 16
When planning the installation location, please note that the clearance needs to be 10 cm on the extract
air side and 20 cm on the supply air side for the intended operation. For maintenance work, a free space
of 70 cm should be observed in front of the unit.
The unit has the protection class IP11. Make sure that the applicable country-specific standards /
regulations for compliance with protection zones when installing the unit in rooms with a bathtub or
shower are observed!
Installation preparations
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 level of the finished wall construction.
The installation of the ComfoSpot 50 is only allowed in connection with the round wall mounting pipe or
with the square wall mounting pipe!
The square wall mounting pipe, intended in particular for new buildings, should be integrated in the outside wall construction
in the course of the wall construction. The round wall mounting pipe is primarily used in the refurbishment and
reconstruction of the building fabric, and is inserted in the outside wall by means of a core hole (
∅
340 mm).
Observe the respective enclosed instructions on professional installation when installing the wall
mounting pipe.
A 230 VAC mains connection for fixed units is to be prepared on site for the mains power supply.
In order to connect an external control panel, a cable must be installed on site between the control panel
and ventilation unit (recommendation: type J-Y(ST)Y 2x2x0.6 LG indoor cable with colour coding in
accordance with VDE 0815).
The mains supply line (e.g. NYM-J 3x1.5) must be installed in the area of the bottom left side of the unit and, where
applicable, the cable to the external control panel, must be installed flush-mounted 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.
Installing the ventilation unit
Prior to starting work, ensure that the mains supply line has no voltage!
The relocation of the internal control panel to the bottom and the installation of a sensor module (optional
accessories) in the unit has to be done prior to installation when the unit is disassembled!
Proceed as follows for the installation of the unit:
1. Adjust the installation length of the unit either to the wall thickness or to the measure of length of the wall mounting
pipe by shortening the EPP housing extension.
The cut must be performed all around, perpendicular to the axis of the EPP pipe extension!
