1. INTRODUCTION
This Installation Manual is intended for professionals, qualified to install VERSO PRO 2 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.
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 manufacturer’s 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 speci-
fied in WEEE Directive (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 equip-
ment for further recycling, contact your city authorities, waste management organisations, 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
ventilation, therefore, we do not recommend using this unit as the main heating/cooling source.
The unit may fail to reach a user-defined supply air temperature when the actual temperature in the
premises differs significantly from the temperature set point, since this will lead to inefficient opera-
tion of a heat exchanger.
All VERSO PRO2 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.
