essary pressure losses in the pipes.
—
Always connect two flexible pipes to the flexible pipe connection.
—
As far as possible, use flexible pipes with a diameter of 75 mm.
—
The total length of each flexible pipe should not exceed 10 m.
—
Minimise the number of bends in the flexible pipes.
—
Run the two flexible pipes of a flexible pipe connection in parallel to one another.
The minimum distance between the flexible pipes must not be less than 3x the
pipe diameter.

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.
