Square mounting block

Intended use

The square mounting block consists of an
EPP block, two dust covers and the interior
installation set for mounting the external cover.
It is used to hold the ComfoSpot 50 ventilation
unit (Fig. 1). For installation, a square wall
opening of at least 360 mm (14 3/16 inch)
must be provided in the exterior wall. The final
wall thickness must be within a range of min.
335 mm (13 3/16 inch) to max. 600 mm
(23 5/8 inch) (Fig. 2).

Preparatory work

Select a suitable installation location in the exterior
wall. Ensure that there is 20 cm (7 7/8 inch)
of clearance on the left side of the room and
10 cm (3 15/16 inch) on the right side from
the wall opening and 70 cm (28 inch) deep
clearance in front to access the unit for routine
maintenance.

Wall opening
The ComfoSpot 50 must be installed in a
plumb vertical wall. The wall opening must be
prepared so the EPP mounting block will sit
plumb and level inside the opening.
The wall opening must not compromise
the load-bearing capacity of the wall
and there must be no load transferred to the
EPP mounting block.
