VENTILATION THE RIGHT WAY
V E N T I L A T I O N & H E A T R E C O V E R Y
3.5
Electrical connection
The working voltage range of the ventilation unit is between 85 V AC and 265 V AC /
50-60 Hz.
NOTICE
If the ventilation unit is not equipped with a mains connection cable and plug or other
means of disconnecting from the mains supply that has, at each pole, a contact opening
width that conforms to the conditions of overvoltage category III for complete separa-
tion, then such an isolating unit (e.g. circuit breaker) must be integrated into the perma
-
nently installed electrical system in accordance with the installation regulations. The
isolating unit must be identified as such and easy to access.

Special notes for installation in solid walls
The installation kit can be installed in solid walls that are at least 30 cm thick (including
internal plaster, external render and insulation).
►
For wall structures that are 70 cm thick or more, you will need 100 cm long outdoor
and exhaust air pipes (M-WRG-LR 100, part no. 5580).
NOTICE
The installation kit fixes the ventilation pipes with a 2° fall to the external wall.
—
The installation kit can be shortened by up to 165 mm (to no less than 273 mm). If
the unplastered wall is thin (30 cm or less), do not cut off the installation kit flush with
the unplastered wall (see section 8.15 on page 34). Allow the kit to protrude into
the external thermal insulation composite system (ETICS) as this is the only way to
allow the ventilation pipes to pass far enough through and so be fixed in place.
—
When fitting the ETICS, make sure that the ventilation pipes maintain their 2° fall.

Special notes for installation in frame constructions
The installation kit can be installed in frame constructions with walls that are at least
30 cm thick (including internal plaster, external render and insulation).

and exhaust air pipes (M-WRG-LR 100, part no. 5580).
