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

not reach the condensate drain if the unit

would be turned around.

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.

Duct insulation, alt. B

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.

Subject to Technical Modifications of GES Energy Small and GES Energy Medium

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.

Subject to Technical Modifications of GES Energy Small and GES Energy Medium

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:

Filters

When the filter timer reaches the set value for filter

change, “Alarm!” will show in the screen saver and ”Chg.

filter” will flash. This means that it is time to clean/change

the filters.

Switch the unit off on the switch on the control panel

or the switch on the electrical panel. Open the front

doors and remove the filters. When the filters have been

cleaned/replaced, close the front doors and reset the

filter alarm by holding down the button below the filter

symbol, until ”Alarm!”, “Chg. Filter” and the exclamation

mark disappears in the filter symbol. The unit reverts to

normal operation.

If the wish is an other time interval this can be adjust in

the User menu.

The fresh air filter (F7) is in the left site of the unit and it

is higher than the extract air filter (G4).

Do not vacuum or clean at high air pressure. It

will damage the filter!

condense tray

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.

Troubleshooting

Safety thermostat in electrical heater

(optional equipment)

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.
