When installing GENVEX 315, 420, 525,
630 & 840 follow these instructions:
1) Adjust the machine in plumb.
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 ows downwards all
the way from the unit.
5) Poor some water into the driptray in the unit
to verify that it is drained properly.
6) If freezing of the water trap may occur, it is
necessary to install a thermostat and electri-
cal heater to prevent freezing, when the tem-
perature drops below +2C°.

Installation
The GE 315 VP(C) to GE 840 VP(C) is available with
supply air on the right-hand side (as shown) or supply air
on the left-hand side AND as a heat exchanger (VP) or as
a reversible cool/heat exchanger.
When it is a left-hand version the unit is build in a mirror
image, which means that the power connection also is
placed on the left-hand side.
Concerning the reversible heat exchanger (VPC) the unit
has two condensate outlets. At all times there will appear
condensation from the heat exchanger. Both outlets must
be connected a suitable drain on site. As well as the single
outlet (VP-version)
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 5-8 litres of condensate per dayTo
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.

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 to the
unit
Connect the escaping 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.
In flats/houses where it is not possible to provide a
sufficient distance between the fresh air and the escaping,
a Genvex airbox may be used.

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
mounted with the necessary fall and be led to an internal
outlet. The condensate drain must be fi tted 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.
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.

Installation
Optimum initial adjustment of plant
Air measuring equipment is used.
Before starting initial adjustment, check that the 5 points
in the inspection and initial adjustment section have been
carried out. Then start up the unit:
Set the initial basic ventilation value, which is speed 2.
To reduce energy consumption as much as possible, first
adjust the main air volumes to the desired air volume by
changing the voltage outlet on the transformer.
Then adjust the supply and extract valves with air
measuring equipment (Remember when performing initial
adjustment of the valves to lock them and to turn the guide
plate in the supply valves so the air blows in the right
direction).
Then check the main air volumes again and fine-adjust the
main air volumes with the fresh air and escaping dampers
(Remember to lock the dampers after initial adjustment).
Maintenance of plant
Filters:
When the red lamp on the control panel flashes, the filters
must be changed/cleaned.
Stop the plant with the switch on the unit or the electrical
panel. Remove the front cover and take out the bag filter
and flat filter. The bag filter may be cleaned two or three
times with a vacuum cleaner before replacing it.
The flat filter can be taken out of its frame and washed in
warm soapy water. Then hold the filter diagonally so the
water runs out. The filter must not be wrung out or washed
in dishwasher. After two or three washes, replace the flat
filter. Replace the flat filter in its frame, set both filters in
the unit and refix the front cover. Then switch on the unit
and press the left-hand button on the control panel for 10
seconds until the red lamp goes out. If it is desired to clean
the filters at a different time interval, this can be adjusted
on the control circuit board filter timer potentiometer,
mounted in the electrical cabinet. Remember to turn off the
current before opening the electrical cabinet.
Condensate drain:
When changing the filter in August/September, before
outside temperatures fall 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 unhindered. 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 three
years. 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 three years 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 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.
