3.7 Roof transit for ducting
Roof transit requirements:
- Must be provided (including materials) by contractor.
- Must be watertight.
Example of a roof transit for ducting
3.8 Roof transits for cabling / plumbing
Caution
Prevent rainwater from following the cables: always bend the cable(s) in a V–
shape.
Note
For a IntrCooll® Plus with a natural ventilator, the use of a roof transit for cabling
is not necessary. With this setup the cabling goes through the natural ventilator
to the unit.
To guarantee a waterproof transit of power cables, control cables and water
supply lines, use commercially available products with the same functionalities as
the examples below:
