Insulation of ducts in
heated spaces
Genvex recommends as follows:
Supply air and extract air ducts
In warm loft spaces the supply and extract channels must
be insulated with 50 mm insulation.
Supply and extract air ducts led through heated spaces in
dwellings do not require insulation. If the supply air duct
has cooling, bypass or earth heat exchanger installed it
must be insulated.
Fresh-air and discharge ducts
In warm loft spaces and warm rooms in dwellings the fresh
and exthaust air ducts must be insulated with minimum 50
mm insulation. In addition, the insulation must be covered
externally with plastic film or aluminium foil in order to
avoid condensate in the insulation.
We recommend an insulation of 100 mm on the fresh air
duct when installing a earth heat exchanger.
Refer to your local distributor for guidance on national
insulation directives.
Optional connection of a
heat-exchanger
The S-models have a heat-exchanger of 0,8 m² mounted
in the tank. A sensor which controls external connections,
such as solar cells, an oil burner or a wood burning boiler
can also be mounted in the sensor pocket. Maximum
diameter of the sensor is 6 mm.
When fitting the piping system in a dwelling, contami
-
nation of the pipes must be avoided. (If required, flush
the piping system with clean water before the unit is
connected). When fitting pipes, it must be ensured that
the pipe connections are not twisted.
Use a pipe wrench to apply counter pressure. If recircu-
lation is not utilized, it must be ensured that the recircu-
lation pipe connection has been tightened properly.
Water connection
The following connectors are placed under the unit:
Condensation drainage hose
¾” RG branch pipe for: Cold water / Recirculation / Hot water
¾” RG branch pipe (2 units) for an extra spiral
(S-models only)
Electrical water heater /
sensor / anode
In the center on the front, behind a steel plate.
Electrical water heater Sensor Anode
Electrical installation
The hook-up to electrical power must be performed by a
certified electrician. (See the enclosed electrical diagram).
The cable connecting the unit to the Design control panel
must be a 4-conductor, 0,25 mm cable with a maximum
length of 50 m.
The unit may only be operated with a full tank.
The unit must always be disconnected from the electrical
power source before the front hatch is dismantled.
Once the unit has been disconnected from the power
main, you must wait until the fan has come to a standstill
before the hatch is opened.
Holes may not be drilled in the unit.
