Installation
When installing the units follow these instructions:
1) Tilt the machine 10-15 mm towards the drainpipe
to allow condensing water to run to drain.
(Does not apply for GES)
2) Install an airtight water trap on a non-freezing
location, to compensate for fan pressure.
3) The water trap hight must be at least 100 mm.
4) Make sure that the drain flows downwards all the
way from the unit.
5) Pour 1 liter water into the driptray in the unit to
verify that it is drained properly. Up to the heating
season make sure that the drain is properly filled
with water.
6) If freezing of the water trap may occur, it is necessary
to install a thermostat and electrical heater to prevent
freezing, when the temperature drops below +2C°.
7) Airflow adjustments must be made on both supply
and exhaust sides for a 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 used.
This instruction must be followed. If the drain is not
made according to this instruction, GENVEX A/S can
not be made responsible for any additional damages,
which have nothing to do with the GENVEX unit.

Dimensions in mm
GE Energy 1 - Installation
The GE Energy 1 is available in a right-hand version (as
shown). For a mirror image unit, the front and rear panels
may be removed, the back panel mounted on the front
and the unit rotated 180°. This will cause the supply to
exchange places with the escaping and the fresh air with
the extract, with the cover on the correct side of the unit.
The drain connection will also be on the opposite side.
The unit must be positioned on a subsurface such that
vibrations from the unit cannot be transferred down through
ceiling and walls and such that the condensate drain with
the necessary trap can be led to an internal drain without
danger of freezing in cold weather, as in the winter period a
unit may produce up to 8 litres of condensate per day.
To allow access for service and maintenance, there must
be a clear space of a minimum of 600 mm in front of the
unit. If the unit is located in the loft, there must be free
access to the unit from the loft hatch.
Bypass:
The GE units can be delivered with modulising bypass or it
can be mounted on site.
Weight: 55 kg
GE Energy 2 - Installation
The GE Energy 2 is available in a right-hand version (as
shown). For a mirror image unit, the front and rear panels

GE Energy 3 - Installation
The GE Energy 3 is supplied in a right-hand version (as
shown) or left-hand version (mirror image), in which the
fresh air exchanges places with the extract air and the
supply air with the escaping air. The drain is also on the
opposite side. The unit has supports and can be installed
directly on a vibration-free sold sub-surface. If oscillation
dampers are provided (extra equipment), these should
be mounted under the supports. In addition it must be
ensured that the condensate drain with the necessary trap
can be led to an internal drain without danger of freezing
in cold weather, as a unit may produce up to 8-10 litres of
condensate per day.
To allow access for service and maintenance, there must
be a clear space of a minimum of 700 mm in front of the
unit. If the unit is located in the loft, there must be free
access to the unit from the loft hatch.
The units are installed with bypass.

Duct connection
All duct connections display a yellow sticker indicating the
type of ventilation channel to be connected.
Connect the supply air:
Duct system from the unit to the supply outlet in the living
room.
Connect the extract air:
Duct system from wet rooms to the unit.
Connect the fresh air:
Duct system from fresh air roof cowls/external grills from
the ground collector to the unit.
Connect the exhaust air:
Duct system from unit to the escaping roof cowls/external
grills.
Duct system
It is recommended that the duct system is executed in
spiral ducting connected with rubber ring seal fittings in
order to provide a leak-free and durable duct system.
To achieve a satisfactory low sound level from the unit,
sound locks must always be fitted to the supply and extract
duct system between the unit and the first supply and
extract fittings.
It is recommended that air speeds in the ducts are
dimensioned at sufficiently low level to prevent noise from
the supply and extract fittings.
When positioning fresh air and extract roof cowls/grills,
make sure 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 provide optimum comfort.

Faulty duct insulation
Condensate drain
The units produce up to 10 litres of condensate per day. It
is therefore important that the condensate drain is correctly
executed and that the unit has a slight fall towards the
condensate drain.
The condensate drain pipe must be air tight for example by
bending a copper pipe as an siphon (see sketch to the left).
Use an armed water hose between the drain connecting
piece on the unit and the siphon and tightend it in both
ends with a collar band.
From the siphon and to the internal outlet there must be
a necessary fall on 1%. The condensate drain must be
fitted with a water trap as there is negative pressure in the
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 below to
ensure that the water in it 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 tape
round the condensate drain pipe.
Insulation of ducts in cold loft spaces
In order to exploit the unit’s high recovery potential
(efficiency), it is necessary to insulate the ducts correctly.
Supply and extract ducts:
To minimise heat losses from the duct system in cold loft
spaces, the supply and extract ducts must be insulated
with a minimum of 100 mm insulation. If insulation form
alternative A is used, it is recommended that it is executed
with two layers of 50 mm lamella mats with paper or foil
externally and with staggered joints between the two
layers. If the ducts are laid on the rafter foot, alternative B
may be used. The insulation must always be tightly packed
round the ducts.
Fresh air and escaping ducts in cold spaces:
It is recommended that fresh air and escaping 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 heating up the fresh air. Take care to seal the
termination where the escaping duct is led through the roof
or through the gable end, in order to avoid condensation
damage.

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. If the supply air duct
has cooling, bypass or earth heat exchanger installed it
must be insulated.
Fresh air and exhaust 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 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.
Reheating of supply air
As the counter current heat exchanger cannot extract all
the heat from the extract air and supply it to the supply air,
the supply air will be about 1-4°C colder than the room
temperature in the dwelling for the whole winter season.
If this lower supply temperature is insupportable during
cold periods, a water-based or electrical reheating surface
can be mounted for reheating the supply air up to room
temperature.
Water-based reheating surface
To protect the water-based reheating surface from frost
burst, a frost protection thermostat must be fitted to the unit
and the surface insulated. The frost protection thermostat
sensor is mounted behind the fins of the water-based
reheating surface. The sensor for controlling the motor
valve is mounted in the supply air channels approx. 500
mm downstream of the water-based reheating surface
in order not to be affected by the radiant heat from the
heating element. The water supply to the water-based
reheating surface must be executed by an authorised
plumbing and heating engineer.
Electrical reheating surface
The sensor for controlling the electrical heating surface
is mounted in the supply air channel approx. 500 mm
downstream of the electrical reheating surface in order
not to be affected by the radiant heat from the heating
element.

Installation
Electrical installation
The electrical connection must be carried out by an
authorised electrical engineer.
See accompaning electric diagram.
The cable between the unit and the control panel is a 4-
conductor 0.25 mm2cable with a maximum length of 50 m.
Optima 100: The cable (RJ 45) between the unit and the
control panel must be max. 10 meters long.
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.
6: If a reheating surface has been mounted on the unit,
set the supply temperature to 0-3°C below the room
temperature in the dwelling.
The unit can now be started up and be allowed to run until
initial adjustment with air measurement equipment has
taken place.

Installation
Optimum initial adjustment of plant
Air measuring equipment is used.
Before starting initial adjustment, check that the 6 points
in the inspection and initial adjustment section have been
carried out. Then start up the unit:
Maintenance of plant - Optima 250 DESIGN
Filters:
When the red lamp on the control panel ashes, the
lters must be changed/cleaned. Stop the unit with 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, 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!
Maintenance of plant - Optima 100
Please pay attension to the red diode wether it is ashing
or constant on. If it is constant on the lters must be
changed. If the diode ashes the lter in the exhaust
hood must be changed.
G4 = Standard lter
(Coarse lter class G4)
F5 = Fine lter (Fine lter class F5)
F7 = Pollen lter (Fine lter class F7)

11
Installation
Condensate drain:
When changing the filter in August/September,
before outside temperatures falls to 5°C, check the
condensate drain for blockage by dirt and check that
there is water in the water trap.
Pour 1 litre water into the condensate tray and make sure it
can run off without problems. If the condensate drain does
not work, this could lead to water damage in the dwelling.
Countercurrent heat exchanger:
Inspect the countercurrent heat exchanger every year. If it
is dirty, remove it and wash in warm soapy water and then
rinse, possibly 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. Remember to shot down the power.
Supply and extract valves:
Clean the valves by wiping 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.
