1. INTRODUCTION
This manual is intended for qualied technicians installing the DOMEKT air handling unit. Qualied professionals are per-
sons with sucient professional experience and knowledge of ventilation systems, their installation, knowledge of electrical
safety requirements and ability to work without risk to themselves or others.
1.1. Safety requirements
To avoid misunderstandings, read this manual carefully before installing the unit.
Air handling unit may only be installed by a qualied technician in accordance with the instructions given in this manual
and in accordance with applicable legal and safety requirements. The air handling unit is an electrical-mechanical device
that contains electrical and moving parts, therefore, ignoring the instructions in the manual not only shall invalidate the
manufacturer’s warranty but can also cause direct damage to property or human health.
• When performing any kind of work, make sure the unit is unplugged from electrical supply.
• Use caution when working near heaters inside or outside the unit, as their surfaces may be hot.
• Do not connect the unit to the power supply network before all the external assemblies are fully
installed.
• Do not connect the unit to the electrical supply, if there is visible damage that occurred during
transport.
• Do not leave objects or tools inside the unit.
• It is forbidden to operate the unit in the premises where there is a risk of release of explosive
substances.
• Use appropriate personal protective equipment (gloves, goggles) when installing or repairing the
unit.

1.2. Design of the units
Domekt CF is an air handling unit with a counter-ow recuperator (heat exchanger). Lamellas of the heat exchange come
in contact with dierent air ows. Exchange of heat or cold takes place between extracted indoor and fresh outdoor air. If no
recuperation is required, the air bypass damper is opened and the heat exchanger is closed. This way the outdoor air passes
around the recuperator and enters the premises directly.

Domekt R – air handling units with a rotary recuperator (heat exchanger). The rotating drum of the rotary recuperator
absorbs heat or cold from the air of the premises, transferring it to the fresh outdoor air. If recuperation is not required, the
rotation of the rotary heat exchanger is stopped.

If the capacity of the heat exchanger is not sucient to reach the temperature set by the user, heaters
or coolers may additionally be switched on1. Heat exchanger and heater (or cooler) are designed to com-
pensate for heating/cooling losses during the ventilation of the premises, thus AHU is not recommended
to be used as main heating/cooling source of the building. AHU may not reach the supply temperature
setpoint if the actual room temperature diers a lot from the desired value, since in that case heat ex-
changer capacity will be low.

Depending on the installation and connection of the ducts, the air handling units are divided into:
• Vertical units – when all ducts are connected at the top.
• Horizontal units – when all ducts are connected on the sides.
• Flat units – thinner units are designed for mounting over suspended ceilings. All ducts are connected at the sides of the unit.

2. UNIT TRANSPORTATION AND STORAGE
Equipment must be transported and stored in the original packaging. During transportation, equipment must be prop-
erly secured and further protected against possible mechanical damage, rain or snow.
L
≥L
Fig. 3. Examples of equipment packaging
Forklift truck or crane can be used for loading or unloading. For the crane operation, special lashes or ropes must be
used to securing them in the designated areas. Ensure that lifting lashes or ropes do not crush or otherwise damage the
housing of the unit. We recommend using special belt supports. When lifting and transporting the equipment with a forklift,
the forks must be long enough to prevent the unit from being overturned or mechanically damaging its bottom side. Air
handling units are heavy, therefore, be careful during lifting, moving or transportation. Use personal protective equipment.
Even small units should be transported on a forklift, a trolley or carried by multiple persons.
L
≥L
Fig. 4. Examples of transportation by crane, forklift and trolley
After delivery of the air handling unit, carefully inspect its packaging for damage. If mechanical or other damage is visible
(e.g., wet cardboard packaging), notify the carrier immediately. If the damage is signicant, do not accept the unit. Inform the
selling company or the representative of UAB KOMFOVENT within three business days about any damage detected during
delivery.1
Units should be stored in a clean, dry room at a temperature of 0-40 °C. When selecting a storage location, make sure the
unit is not accidentally damaged, that other heavy objects are not loaded on top and dust or moisture does not get inside
the unit.
Before installation AHU must be stored in clean and dry premises in their original packaging. If the unit
is installed but not yet in use, all connection openings must be tightly closed and the unit must be ad-
ditionally protected against environmental inuences (dust, rain, cold, etc.).
1 UAB KOMFOVENT is not responsible for losses caused by the carrier during transportation and unloading.

3.2. Installation site requirements
DOMEKT units are designed for installation in household or technical rooms with an air temperature of 0 °C to +40 °C,
relative humidity from 20% to 80% (non-condensing). It is recommended to install the air handling unit in a separate room or
in an insulated attic on a solid, level base with vibration damping mat. We recommend not to rest the unit against the wall to
prevent noise or vibration and accumulation of moisture or mould on the wall due to condensation.
It is forbidden to install DOMEKT air handling units outdoors. They are also not designed for ventilation
or dehumidication of humid premises (swimming pools, baths, car washes, etc.).
Make sure that children will not reach and will not play with air handling unit without adult supervision.
With additional accessories, DOMEKT R units can also be installed in unheated premises (for example
an attic), where ambient temperature is below 0°C. In this case, additional air closing dampers must be
installed in the supply and extract air ducts (on the room side). It should prevent warm indoor air from
circulating inside the unit when it is stopped to avoid condensation damage to the electronic compo-
nents. It is also necessary to insulate all ducts passing through unheated rooms.

3.2.1. Maintenance area
When selecting the installation or mounting location of the unit, provide unrestricted and safe access to the equipment
for its repair or preventive maintenance. The inspection opening (if any) should not be less than the size of the unit and the
installation must allow easily dismantlement if necessary (e.g. in the case of complicated repairs). Minimum space for main-
tenance refers to an area free of any xed or immovable equipment, constructions, walls, structures or furniture.

• It is forbidden to drill or screw into the casing of the unit, in places not provided for purpose, as there is a
danger of damaging cables or tubes inside the housing.
• Domekt CF 150 F, CF 500 F and CF 700 F at units must be tted with a 15 mm slope on the drainage side
to facilitate the discharge of condensate from the unit.
• Only these units can be mounted on the ceiling or wall and only in such positions as specied in Fig. 6.
3.2.2. Humidity in the installation room
If the unit is installed in a room with high humidity, condensation may occur on the walls of the unit in cold weather
conditions (see Fig. 7). Newly built ats or homes have high probability of condensation, especially in the rst year, until the
construction or nishing materials haven’t dried up completely. When installing the unit in the rooms with a high probability
of condensation, it is necessary to ensure that the condensate does not damage the building structures or furniture.
To reduce condensation on the outside of the AHU, the following is recommended:
• Ensure proper ventilation of the room where the AHU is installed.
• Maintain a lower relative humidity in the room where the AHU is installed.
• Install a pre-heater to increase the air temperature of the outdoor air entering the unit.
• If the air is drier outside, you can increase the ventilation intensity and the temperature settings so that the rooms are
dried faster. For this purpose, you can also use the “Humidity control function” (see “Domekt User Guide”).
If the unit is shut down in cold outside temperatures, due to free air circulation, condensate can form inside of the unit,
therefore, it is important to install air closing dampers (motorized are recommended) to close the air intake and exhaust
openings when the unit is OFF. This will prevent cold air from the outside and warm air from the premises to enter the unit.
We recommend that you always keep the unit turned on and use it at minimum of 20% intensity even
if no ventilation is required. This will ensure good indoor climate conditions and reduce condensation
inside the unit, which might damage electronic components.

3.4. Location and dimensions of xture elements
Special brackets, wall screws with plastic bushings and self-tapping screws are provided for mounting the units. When
mounting the units, care must be taken to ensure that vibrations of the unit are not transmitted to the building structures,
as it may lead to additional noise. In order to eliminate vibrations, additional anti-vibration gaskets are attached to the back
wall of the unit. Some units are supplied with factory tted anti-vibration gaskets; in other cases, they are supplied sepa-
rately. In case of ceiling-mounted units, vibration absorbers are integrated in mounting brackets.
Below are the types of brackets and their mounting dimensions.

3.5. Duct system installation
The air in and out of the unit ows through the duct system. The duct system should be designed and selected to have
low airow rates and low pressure dierentials, ensuring more accurate airow rates, lower energy consumption, lower
noise levels and longer life of the unit.
Outdoor vents must be installed as far apart as possible on dierent sides of the building to prevent the exhaust air from
returning to the air intakes. Try to install the air intake vents where the outdoor air is the cleanest: do not direct them towards
the street, car park or outdoor replace. We also recommend installing the air intake vent on the north or east side of the
building, where the heat of the sun in summer will not have a signicant eect on the supply air temperature.
It is highly recommended to install unit connecting ducts of supply inlet and exhaust outlet with a minimum slope on the
outside of the premise, to avoid water owing into the unit in case of rain or snow.

It is recommended to insulate the ducts in unheated rooms (attic, basement) to avoid heat loss. It is also recommended
to insulate the supply air ducts if the unit is used for room cooling.
The air ducts are tted to the unit with self-tapping screws. Dierent air ow duct positions are marked on the sticker
located on the AHU:

Fig. 8. Air duct marking
Most units with a rotary heat exchanger also have a fth branch (labelled E) to connect an additional exhaust duct (see 1.3.
section). The airow through this opening is delivered directly to the exhaust fan, bypassing the lters and heat exchanger,
therefore, you can connect ducts from the bathroom, toilet, or kitchen in cases when there is no additional extraction fan in
these premises. However, air is extracted through an additional branch without recuperation, thus reducing the eciency of
the heat exchanger. For this reason, we do not recommend using the extra air extraction continuously. An additional exhaust
duct should be tted with air closing damper (motorized are recommended) and should only be opened when additional
extraction is required (e.g. when bathing). If the additional branch is connected to the kitchen hood with an integrated clos-
ing damper, an additional damper is not needed.
