3. Installation
3.1 Positioning
The ventilator can be installed in many different positions. However, it should always be possible to
open the access door at least 80 degrees, and the locking bolts should always be accessible.
Acceptable ventilator positions are shown below in Fig. 3. Note that the ventilator motor can never
point straight down as this could cause condensation build-up around the shaft, which can shorten
the product life.
Never install the ventilator so the motor points down. This will shorten the
life.
3.2 Floor or Roof Mounting
To minimize the transfer of noise and vibration the ventilator should be placed on a surface that is
level, stable and vibration-free. The ventilator does not need to be secured by any means. See Fig. 4
on page 7.
Once the installation location has been selected the support legs must be installed.
For the standard position bolt holes are pre-drilled so the legs should just be aligned and secured
with the enclosed sheet metal screws.
