1. INTRODUCTION
This Installation Manual is intended for professionals, qualified to install Verso Standard air handling units. Qualified pro-
fessionals are people with sufficient professional experience and knowledge of ventilation systems and installation thereof,
knowledge of electrical safety requirements and having ability to perform works without endangering themselves or others.
See the KOMFOVENT website for user manuals.
1.1. Safety Requirements
To avoid misunderstandings, read this Instruction Manual carefully before installing air-handling unit.
Only a qualified professional in accordance with the manufacturers instructions and applicable legal acts and safety re-
quirements may install air-handling units. An air handling unit is an electrical-mechanical device that contains electrical and
moving parts, therefore, disregarding instructions of this manual will void the manufacturer’s warranty and may also cause
direct damage to property or human health.
Before starting any tasks, make sure that the unit is unplugged from the mains.
Use caution when performing works near internal or external heaters as their surfaces may be hot.
Do not connect the unit to the mains unless all the external assemblies are installed completely.
Do not connect the unit to the mains in case of any visible damage incurred during transportation.
Do not leave foreign objects and tools inside the unit.
It is forbidden to operate air-handling units in areas with potentially explosive atmospheres.
Use appropriate safety equipment (gloves, goggles) when performing installation or repair works.
This symbol indicates that this product may not be disposed of with your household waste as specified in WEEE Di-
rective (2002/96/EC) and national laws. This product should be handed over to a designated collection point or to an
authorised collection site for recycling waste electrical and electronic equipment (EEE). Improper handling of this type
of waste could have a negative impact on the environment and human health due to potentially hazardous substances
that are generally associated with electrical and electronic equipment. At the same time, your cooperation in the correct
disposal of this product will contribute to the effective usage of natural resources. For more information about where
you can drop off your waste equipment for further recycling, contact your city authorities, waste management organisa-
tions, approved WEEE scheme or your household waste disposal service.
1.2. Unit Types and Sizes
An air-handling unit is a device designed to ensure good ventilation in the premises. An air- handling unit removes indoor
air containing carbon dioxide, various allergens or dust, while replacing it with filtered fresh air from outside. As the outside
air is usually colder or warmer than the air within the premises, an integrated recuperator (heat exchanger) collects thermal
energy from the indoor air and transfers the majority of it to the supply air. When a recuperator is not capable of reaching a
desired temperature, additional heaters or coolers may be activated.
Heat exchangers and heaters (or coolers) are designed to compensate for heat/cool losses during ven-
tilation, therefore, we do not recommend using this unit as the main heating/cooling source. The unit
may fail to reach a user-dened supply air temperature when the actual temperature in the premises
diers signicantly from the temperature set point, since this will lead to inecient operation of a heat
exchanger.
Verso Standard air handling units are manufactured in different sizes and various air flow ranges (from 1000 to 7000 m3/h).

1.2.1. Unit types by heat recovery type
All Verso Standard air handling units are divided into 3 groups according to the type of recuperator (heat exchanger)
used:
Verso R - air handling units with rotary heat exchangers. Rotating wheel (rotor) of a rotary heat exchanger collects heat
or cold from the indoor air and transfers it to the fresh supply air. Recovered heat/cold capacity is changed by adjusting the
rotor speed. When heat recovery is not required, the wheel stops.

Verso CF – air handling units with counter-flow recuperators (heat exchangers). Plates of a heat exchanger come in con-
tact with different air flows and so heat exchange between extracted and incoming fresh supply air takes place. Amount of
recovered heat or cold is controlled by adjusting the air bypass damper position. When recuperation is not required, the air
bypass damper is opened and the heat exchanger is closed. This way, the outdoor air bypasses the heat exchanger and flows
directly in to the premises.

During operation of AHU with counter-flow heat exchanger condensate is forming and it can freeze at negative outdoor
temperatures. If there is a risk of freezing, heat exchanger defrost procedure is started (see user manual). During the defrost-
ing cycle an air bypass damper is opened and cold outdoor air is directed to heating devices bypassing the heat exchanger,
therefore, during the defrosting cycle the supply air temperature briefly decreases. To reduce temperature fluctuations dur-
ing defrosting and to ensure that the heat exchanger will not freeze, even at very low outdoor temperatures, it is recom-
mended to install a preheater, which should heat up air entering AHU to at least -4°C.

1.2.2. Unit types by duct connections
Depending on the installation and connection of the ducts, the air handling units are divided into:
Vertical units (marked by the letter V) – when all ducts are connected at the top of the unit.
Horizontal units (marked by the letter H) – when all ducts are connected on the sides of the unit.
Flat units (marked by the letter F) – thinner units, which are designed for mounting over suspended ceilings. All ducts
are connected on the sides of the unit.
Universal units (marked by the letter U) – which duct connections can be relocated from the sides of the unit to the
top and vice versa. Each universal unit has 16 different duct layout options that are easy to change during installation,
depending on the intended installation location.
Horizontal unit Vertical unit Flat unit

Fig. 2. Relocation of duct connections of the universal units
1.2.3. Unit types by inspection sides
Also, each unit may be left or right inspection side1. The inspection side indicates which side of the unit contains the air
supply duct to the premises. The exact arrangement of the duct connections for the different inspection sides can be found
in section “Unit components”.

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.
Fig. 4. 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.

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 significant, 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 040°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.
Air handling units are heavy, therefore care must be taken during lifting, carrying or moving operations.
Use personal protection equipment, do not stand under a suspended unit or a part thereof.
Only an employee qualied to operate a forklift truck or crane and familiar with the principles of
cargo lifting and safety requirements, must perform unloading or lifting operations.
It must be ensured that the casing is not crushed or otherwise damaged by straps or ropes during lift-
ing operations. Use of special supporting structures (traverses) is recommended.
When lifting the unit or section thereof, note that their center of gravity may dier from the geomet-
ric center of the load.
Mounting of separate air handling units in stacks is not allowed unless its construction design is in-
tended for such installation.
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 additionally 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. MECHANICAL INSTALLATION
3.1. Requirements for Mounting Location and Installation Base
Verso Standard air handling units are designed for ventilation of medium or large commercial or industrial premises (e.g.,
stores, offices, hotels, etc.) where standard air temperature and humidity is maintained. These units are not intended for
transporting solid particles within air flows. Standard equipment air handling units are intended for indoor installation; and
with additional accessories, these units may be mounted outdoors. Air handling units are designed for ambient tempera-
tures from -30°C to +40°C.
Verso Standard units are not intended for operation in areas with potentially explosive atmospheres.
Air handling units are not designed for ventilation and dehumidication of wet areas (pools, saunas,
car washes, etc.).
If the AHU is installed in a room with high humidity level, condensate may form on the walls of the
unit at low outdoor temperatures.
An air handling unit must be mounted on a relatively large and sturdy base, based on the weight of the unit and in ac-
cordance with building regulations. Base must be made of reinforced concrete or metal structures. If the unit is not equipped
with adjustable height feet, it must be installed on a flat base. Vibration dampening gaskets must be fitted between the unit
and installation base.
The outdoor air handling units must be xed to the installation base (e.g., metal angle pieces with rub-
ber vibration dampening gaskets).
Units installed on such base must be levelled in respect to the horizon – deviations shall not exceed 0.3mm for 1m in the
longitudinal direction and 0.5mm for 1m in the transverse direction. If installation base is uneven, it is recommended to in-
stall the unit on the mounting frame with adjustable feet, which should be ordered separately. Some units are manufactured
with factory-assembled mounting frame for separate sections of the unit. If necessary, adjustable feet may be ordered for
such frame.

Flat units are usually attached to the ceiling, floor slab or other horizontal structures with the doors down. For this pur-
