Subject to Technical Modications

When installing GENVEX Premium-series
and Premium range, please follow these
instructions:
1) Make sure that the machine is in plumb.
2) Install an airtight water trap on a non-freezing
location to compensate for fan pressure.
3) The height of the water trap must be at least
100 mm.
4) Make sure that the drain ows downwards all
the way from the unit.
5) Pour some water into the drip tray of the unit
to verify that it functions properly.
6) If freezing of the water trap may occur, it
is necessary to install a thermostat and an
electrical heater to prevent freezing when the

temperature drops below +2C°.
7) Air ow adjustments must be made on both
the supply and exhaust side prior to normal
use of the machine. It is important to have
a balance between supply and exhaust air
volumes
8) It is recommended to keep the ducts closed
until the unit is adjusted and working.
This instruction must be followed. If the drain is
not made according to this instruction GENVEX
A/S cannot be made responsible for any additio-
nal damages, which have nothing to do with the
GENVEX unit.

Installation
Dimensions in mm Installation
The GE Premium range is available with supply air on the
right-hand side (as shown) or supply air on the left-hand
side and as a reversible cool/heat exchanger.
When it is a left-hand version the unit is build laterally
reversed, which means that the power connection is placed
on the left-hand side.
Because it is a reversible heat pump the unit has two
condensate drains. At all times the condensation from the
heat pump will appear. Both outlets must be connected to a
suitable drain on site.
The unit must be positioned on a surface so that vibrations
from the unit cannot be transferred through ceiling and
walls and so that the condensate drain with the necessary
water trap can be led to an inside drain without danger
of freezing in cold weather. In the winter period the unit
may produce up to 5-8 litres of condensate each day. To
allow access for service and maintenance, there must be
a space of a minimum of 600 mm in front of the unit and
a current floor. If the unit is located in the loft space, there
must be free access to the unit from the loft hatch.

Duct connection
At all duct connections there is a yellow sticker indicating
which ventilation duct to be connected.
Connect the supply air duct:
Duct system from the unit to the supply outlet in the living
room
Connect the extract air duct:
Duct system from wet rooms to the unit.
Connect the fresh air duct:
Duct system from fresh air roof cowls/external grills to the
unit
Connect the escaping air duct:
Duct system from unit to the escaping roof cowls/external
grills.
Duct system
It is recommended that the duct system is made of spiral
ducting with rubber ring seal fittings in order to provide a
tight and durable duct system. To achieve a satisfactory low
sound level from the unit, silencers must always be fitted
to the supply and extract air duct system between the unit
and the first supply and extract valves.
It is recommended that the air speed in the ducts are
dimensioned at a sufficiently low level to prevent noise from
the supply and extract valves.
When positioning fresh air and extract roof cowls/grills,
make sure that the two air flows do not intercept causing
escaping air to be drawn in again. It is recommended that
grills are placed on the north or east side of the house to
ensure optimum comfort.
In flats/houses where it is not possible to provide a
sufficient distance between the fresh air and the escaping.

Faulty duct insulation
Condensate drain
The units produces up to 5-8 litres of condensate per
day. It is therefore important that the condensate drain is
correctly made and that the unit has a slight fall towards
the condensate drain. The condensate drain pipe must
be mounted with the necessary gradient and be led to an
internal outlet. The condensate drain must be fitted with a
water trap as there is negative pressure in the air chamber
in which the condensate tray is mounted.
If the unit is installed in a cold loft space, the condensate
drain pipe must be insulated to prevent freezing of the
condensate in the pipe.
However, it is recommended that the water trap is installed
in a heated space to ensure that the water does not freeze.
If installation problems make it impossible to secure the
condensate drain pipe from freezing by insulation, it will be
necessary to mount a thermostat-controlled heating coil
round the condensate drain pipe.
Insulation of ducts in cold loft spaces
In order to high recovery rate of the unit, it is necessary to
insulate the ducts correctly. Supply and extract ducts:
Supply and extract air duct :
To minimize heat losses from the duct system in cold loft
spaces, the supply and extract ducts must be insulated with
minimum a 100 mm insulation mat. If insulation type A is
chosen, it is recommended that it is done with two layers of
50 mm mats wropped with paper or foil on the outside and
with staggered joints between the two layers. If the ducts
are positioned on the rafter foot, type B may be chosen.
The insulation must always be tightly wrapped round the
ducts.
Fresh air and exhaust air ducts in cold spaces :
It is recommended that fresh air and exhaust air ducts
are insulated with a minimum of 50 mm insulation. The
fresh air duct is insulated to prevent warm air in the loft in
summer from heat up the fresh air. Make sure to seal the
termination where the escaping duct is led through the roof
or through the gable end in order to avoid condensation
damage.

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.

Installation
Optimal commissioning of the ventilation
system
Air measuring equipment is necessary for commissioning.
Before starting adjusting the system make sure that the 5
points in the section commissioning of the unit have been
carried out. Then start up the unit.
The basic ventilation value adjustment is to be done on
speed 2. To reduce energy consumption as much as
possible, start by adjusting the main air volumes to the
desired air volume by changing the voltage outlet on the
transformer.
Then adjust the supply and extract air valves with air
measuring equipment (when adjusting the supply and
extract air valves, remember to lock them and to turn the
guide plate in the supply air valves so the air blows in the
right direction).
Then measure the main air volumes again and do the
finaladjustment of the main air volumes with the fresh and
extract air dampers (Remember to lock the dampers after
commissioning).
Maintenance of the unit
Filters:
When the red lamp on the control panel ashes, the lters
must be changed/cleaned. Stop the unit on the switch
on the unit or the electrical panel. Open the front cover
and take out the lter. When the lter has been changed
or cleaned by shaking it and by removing the worst dirt,
and mounted again switch on the unit and press the enter
button on the control panel for 10-15 seconds until the
Genvex logo starts ashing again and the equipment is
back in normal operation.
Careful handling of the plates is required. They
have sharp edges and must not be damaged.
Do not vacuum or clean at high air pressure. It
will damage the lter!
Remember: do not open the unit, before it has
been disconnected from the electricity
Condensate drain:
When changing the filter in August/September, before
outside temperatures fall to 5°C, measure that the
condensate drain is not blocked by dirt and make sure that
there is water in the water trap.
Pour 1 litre of water into the condensate tray and make
sure it runs off without hindrance. If the condensate drain
does not work, this could lead to water damage in the
dwelling.

Counter current heat exchanger:
Inspect the countercurrent heat exchanger every years. If
it is dirty, remove it and wash in warm soap water and then
rinse, if possible in the bathroom using the shower head.
Fans:
Every year check the two fan wheels for dirt. If they are
dirty they may be cleaned with a brush, bottle washer etc.
Supply and extract valves:
Clean the valves by wiping them with a dry cloth. Make
sure the valve does not rotate causing a change in the air
volume.
Service:
If you are unable to maintain your unit yourself, you
can sign a service agreement with the Genvex service
department. If any faults arise in the unit, contact the
Genvex service department.
