m
Danger to life due to electric shock!
An electric shock can result in death or serious injury�
– Ensure that the unit is voltage-free and isolated from the mains power supply. Ground and short circuit the unit, shield
neighbouring live components
Dispose of all components and filters and disused operating materials (e.g. oil, refrigerants) in an environmentally-friend-
ly manner in accordance with the local codes, practices and environmental regulations.
An authorised specialist waste processing company must dispose of the unit or the individual components. The ap-
pointed contractor must ensure that:
– the components are separated according to material types.
– the used operating materials are sorted and separated according to their respective properties.
The controller of this product contains batteries. According to the battery law (BattG) we are obliged to inform you
about the following:
Batteries and rechargeable batteries must not be disposed of with household waste. You are legally obliged to return used
batteries and accumulators. You can return batteries and accumulators free of charge to retailers or municipal collection points.
Batteries or rechargeable batteries that contain harmful substances are marked with a crossed-out dustbin symbol.
Under the garbage can symbol is the chemical designation of the pollutant.
Cd for cadmium / Pb for lead / Hg for mercury
Think of our environment, with the return you make a substantial contribution to environmental protection!

Danger to life due to electric shock!
The installation and connection of the unit may only be carried out by qualified specialist personnel. The electrical con-
nections must be carried out by a person who has proper professional training and experience in the relevant accident
prevention regulations, as well as other generally recognised safety and occupational health codes, with authorisation
to perform work on the unit.
Risk of injury due to electric shock, hot surfaces and potentially hot surface of optional auxiliary heater�
m
Danger to life due to electric shock!
The unit must be fully isolated from the mains power supply before all maintenance and installation work and
opening the terminal compartment! The electrical connections must be carried out in accordance with the
relevant wiring diagram and must only be carried out by qualified electricians� The electrical connection must
be fully isolated until the final assembly!
2�4�1 General mechanical assembly
The central ventilation unit AIR1 XVP.. must be installed in the upright position. Due to noise levels, which change
depending on system pressure, it is recommended that the compact ventilation unit is installed in the utility room or
storage room. It must be ensured that there is a waste water connection in the installation area. In this respect, please
consider the condensation outlet information!
The assembly should take place in such a way to enable the shortest possible ventilation ducts and trouble-free con-
nection to the unit. Tight bends result in increased pressure losses and flow noises.
The unit can be turned 180° for optimal installation, so that the inlets and outlets for the outside air/exhaust air and
extract air/supply air can be on the left or right side of the unit. With regard to these properties, bends and long pipe
sections are not required. In addition, the heat loss is reduced and the system efficiency is increased.
Important note:
– The ventilation ducts must not become kinked.
– The connections to the connectors must be firm and tight.
– The flange connections must be leakproof and firm.
– If necessary, anti-vibration mounts can be used on site between the base of the unit and the floor.
Ensure that the unit is positioned on a flat surface before the start of installation work.
Assembly area
The AIR1 XVP.. ventilation units are exclusively intended for installation in frost-free indoor spaces
(room temperature > 0 °C).
The following criteria must be observed when installing the unit to ensure easy accessibility for maintenance and main-
tenance work (Fig.4).
