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.
This sign means that the product may not be disposed of together with your household waste as dened in Directive
(2002/96/EC) and national legislation on the management of WEEE. This product must be disposed of at an appropri-
ate collection point or recycling facility for waste electrical and electronic equipment (WEEE). Improper handling of
this type of waste due to hazardous substances inside electrical and electronic equipment can endanger the environ-
ment and human health. By helping to ensure proper disposal of this product, you will also contribute to the ecient
use of natural resources. For more information on how to dispose of such waste for further recycling, contact your city
authorities, waste management organisations, approved WEEE systems or your household waste management bodies
representatives.

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.

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.
