When installing the GES Energy follow these instructions:

1) Turn off the electricity before opening the unit

2)  Install an air tight water trap on a non-freezing location to 

compensate for the fan pressure.

3)  The height of the water trap 

must be at least 50 mm.

4) Make sure that the drain flows downwards all the way 

from the unit.

5)  Pour 1 liter water into the drip tray of the unit to verify that 

it is drained properly. Before each heating season make 

sure that the drain is filled with water. 

6) If freezing of the water trap occurs, it is necessary to 

install a thermostat and electrical heater to prevent 

freezing when the temperature drops below +2 C°.

7) Air flow adjustments must be made on both supply 

and exhaust air sides before use of the machine. It is 

important supply and exhaust air volumes are balanced.

8)  It is recommended to keep the ducts closed until the unit 

is started and the system is adjusted.

This instruction must be followed. If the condensate 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.

GES Energy 1 - Installation

The GES Energy 1 is supplied in a vertical version (as 

shown) or a horizontal version.

The vertical version cannot be used as a horizontal 

version and vice versa. One of the reasons being that the 

condensate water would not reach the condensate drain if 

the unit would be turned around.

The unit must be positioned so that the condensate drain 

with a necessary trap can be properly led to an internal 

drain. In the winter period a unit may produce up to 6 

litres of condensate water 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.

Weight: 32 kg

 

The vertical version cannot be used as a 

 

horizontal version and vice versa. One of the 

 

reasons being that the condensate water would

Duct connection

All duct connections are with a yellow sticker indicating the 

type of ventilation pipe to be connected.

Connect the supply air        :

Duct system from the unit to the supply outlet in the living 

area.

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 or 

the ground collector to the unit.

Connect the exhaust air         :

Duct system from unit to the escaping roof cowls/external

grills.

Condensate drain

The units produce up to 6 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.

Optimal operation is achieved by mounting a 

connector piece Ø 160 mm in each outlet of the 

GES Energy and tighten them with the supplied 

collar bands.

While operating there will be a low pressure in 

the unit it will therefor be neccesary to make 

sure that the height difference is min. 50 mm 

to the water in the siphon.

Faulty duct insulation

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.

Minimum distance: 3 m between supply and exhaust air

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.

Genvex recommends as follows:

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.

Refer to your local distributor for guidance on national 

insulation directives.

Insulation of ducts in heated spaces

Genvex recommends as follows:

Supply and extract 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 exhaust 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.

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.

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 cable for Optima 250, with a maximum length 

of 50m and a 8-conductor cable for Optima 100 with a 

maximum length of 10m.

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.

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:

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. 

Before the counter current heat exchanger can be moved, 

the front of the condense tray have to be opened. There is 

a snap lock in the right site of the condense tray. 

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. 

By demounting the front it is important to remove the 

filters before the front is removed.

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.

If an error occurs on an electrical heater, the safety ther-

mostat will disconnect. 

The heater is equipped with a fire thermostat that auto-

matically cuts off the power supply, if the temperature 

exceeds 80 °C. If the temperature decreases, the heater 

automatically re-engages.

As an additional security there is a built-in thermal cut-out, 

which disengages if the temperature exceeds 110 °C. Re-

engaging must be done manually.

Does not apply to PTC electrical heaters.
