2.5.7. Preparing for Installation
The following steps should be taken before the professional installation:
Unpack the unit.
Check the completeness of the contents. Your delivery has the following
components:
1 x Ventilator with Heat Exchanger Installation Unit
1 x Piping Segment Consisting of 3 Elements Assembled
2 x Round-head Screws with Square Neck
2 x Screw Nuts
1 x Inner Cover
1 x Outer Cover
1 x Sealing Ring (Self-Adhesive )
Remove the installation unit (ventilator with heat exchanger) from the piping and
secure it against damage such as knocks or contamination.
The heat exchanger is made of ceramics and can be easily damaged by knocks
or falling!
2.5.8. Cabling
Cable Connecting
To connect the control in the provided location, the room must have 230 V cabling. In the new
building, in particular, at least one empty wiring conduit leading to the place of future control is
recommended to be provided before plastering.
Please, note that this service can only be provided by an authorized supplier
representative (e.g., electrician) in Germany.
Cabling Ventoxx RV ventilation units
Low-voltage cables must lead from the control to the relevant associated fans. For this a wiring
with a cable cross-section 3 x 0.75mm² is sufficient. As a power feed cable (connection
between electrical power network and transformer) a wiring with a cable cross-section not less
than 3 x 1.5mm² is sufficient. Please, note that there should be enough overhang at both ends
to connect the control and the fan. An overhang of 40 cm should be provided.
In an old building, laying low voltage cabling in corners and under wallpaper is
recommended to ensure minimum intervention to the existing inventory.
