vention and environmental protection regulations must be observed for the area of use of the unit. It is the duty of the oper-
ator to ensure that instructions relating to maintenance (e.g. relating to hygiene) are complied with.
2.1 Correct use
The units are only intended to be used for heating and cooling air in frost-free and dry rooms. Within the room, the unit
needs to be connected to the building's heating/cooling/ventilation system and to the building's waste water and power net-
work. The operating limits and limits of use described in Chapter 2.2 [}6] must be observed.
IMPORTANT NOTE!
Only use the unique after completion of the complete building and system. Site heating is not deemed to be
correct and proper use.

IMPORTANT NOTE!
Danger of frost in cooling mode!
There is a risk of the heat exchanger freezing when used in unheated rooms.
Make sure that the unit is equipped with a frost protection sensor and/or thermostat in this case.
IMPORTANT NOTE!
Warning of misuse!
In the event of misuse, as itemised below, there is a danger of limited or failing operation of the unit. En-
sure that the airflow can circulate freely.
Never operate the unit in humid areas, such as swimming pools, wet areas etc.
Never operate the unit in rooms with an explosive atmosphere.
Never operate the unit in aggressive or corrosive atmospheres (e.g. sea air).
Never operate the unit above electrical equipment (such as switch cabinets, computers or other electrical
units, or contacts that are not drip-proof).
Never use the unit as a construction site heater.
Never operate the unit in areas with a high dust content.
IMPORTANT NOTE!
Energy losses due to misuse!
Operating the unit with open windows (or other room openings) can result in significant energy losses.
Heating and cooling modes (particularly when operating different units) need to be coordinated with
each other.
2.3 Risk from electrocution!
DANGER!
Risk of fatal injury from electrocution!
Contact with live parts will lead to fatal injury from electrocution. Damage to the insulation or individual
components can lead to a fatal injury.
