Insulation of ducts in heated spaces
Supply and extract ducts:
In warm loft spaces the supply and extract channels must
be insulated with 50 mm insulation.
Supply and extract ducts led through heated spaces in
dwellings do not require insulation.
Fresh air and escaping ducts:
In warm loft spaces and heated rooms in dwellings the
fresh air and escaping ducts must be insulated with
minimum 50 mm insulation. In addition the insulation must
be covered externally with plastic fi lm or aluminium foil in
order to avoid condensate in the insulation.
Electrical installation
The electrical connection must be carried out by an
authorised electrical engineer.
See accompanying wiring diagram.
The cable between the unit and the control panel is a 4-
conductor 0.25 mm2 cable with a maximum length of 30 m.
Inspection and initial
adjustment of appliance
To achieve optimum running of the unit it must be initially
adjusted with air measuring equipment.
To start up the unit before adjustment, do as follows:
Before starting up the unit:
1: Check that the Genvex unit is correctly mounted and
that all ducts are insulated as required.
2: Check that hatches can be opened so that service and
maintenance on the unit can be carried out.
3: Check that filters are clean (may be dirty from
installation work).
4: Check that the condensate drain is correctly mounted
with water trap and is protected from freezing. Pour 1
litre water into the condensate tray and make sure it
can run unhindered through the condensate drain pipe.
5: Set all supply valves such 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 intermediate valves by 4-7 turns depending
on how far they are from the unit.
The unit can now be started up and be allowed to run until
initial adjustment with air measurement equipment has
taken place.
