Preparing for installation
A vertical outer wall and a flat surface on the outside of the shell wall are required to properly install the
embrasure module. Any uneven surfaces must be compensated for in the area where the embrasure
module is fitted to the shell wall surface.
Drilling the core hole
Before drilling the core hole, select one of the four possible embrasure module installation variants. The minimum wall
thickness must be 335 mm. If the shell wall is not thick enough, the difference must be compensated for by placing
insulation under the embrasure module in the thermal insulation composite system plane.
1. Determine the core hole position based on the relevant installation variant in section

versions
.
Ensure that there is sufficient clearance around the installed ComfoSpot 50 unit and that there is enough room for
maintenance work to be carried out (at least 39 cm on the left, 29 cm on the right, 70 cm at the front and 20 cm at
the top – in relation to the pipe axis of the wall mounting pipe; viewed from the inside of the outer wall).
2. Drill the core hole (

340 mm) in the horizontal axis of the drill hole, observing the explanations given in section

Preparatory work for direction-change adapter installation
Depending on the intended installation variant, the moulded parts serving as duct closure openings must be separated
from the EPP housing and the fixing clips (1) must be attached.
The processing measures are shown in the following sections based on installation variant 1: ODA and EHA duct on the
left.
When installed, the
OBEN / TOP
embossing on the EPP housing must be positioned at the top.
1. Use a sharp knife or a fine-tooth saw to carefully cut off the EPP moulded parts in the profile groove (white dashes)
of the relevant duct connections. The separated EPP moulded parts are to be inserted as blanking plugs in the duct
adapters (8) to protect against contamination until the facade is finished and the discharge grilles (10) are installed.
