Installation
Insulation of ducts in warm spaces
Supply and extract air ducts:
In warm spaces the supply and extract channels must be
insulated with 50 mm insulation.
Supply and extract ducts in heated spaces do not require
insulation.
Fresh air and xhaust air ducts:
In warm loft spaces and warm rooms the fresh and
exhaust air ducts must be insulated with minimum 50 mm
insulation. In addition, plastic or aluminium foil must be
wrapped around the insulation in order to avoid condensate
in the insulation.
Electrical connections
The electrical connection must be carried out by an
authorised electrician.
See the electrical diagram.
The cable between the unit and the control panel is a 4-
conductor 0.25 mm² cable with a maximum length of 50 m.
Commissioning of the unit
To achieve optimal running of the unit it must be adjusted
with air measuring equipment.
If you wish to start up the unit before adjustment, do as
follows.
Before starting up the unit:
1: Make sure that the Genvex unit is correctly mounted
and that all ducts are insulated as required.
2: Make sure that inspection doors can be opened so that
service and maintenance of the unit can be carried out.
3: Make sure that filters are clean (may be dirty from
installation work).
4: Make sure that the condensate drain is correctly
mounted with a water trap and is protected from
freezing. Pour 1 litre water into the condensate tray and
make sure that it can run through the condensate drain
pipe without hindrance.
5: Adjust all the supply valves so that the valve closest
to the unit is opened three turns from closed position,
while the furthest is open eight turns from closed
position. Open the valves in between 4-7 turns
depending on how far they are from the unit.
The unit can now be started up and run until adjustment
with air measurement equipment has been carried out.
