1 General
Ventilation units from the FRÄNKISCHE profi-air product range constitute an important part of a heat recovery ventilation sys-
tem. They bring the required volume of supply air to and take extract air from rooms. With the help of an integrated plastic
cross-flow heat exchanger, these ventilation units provide high heat recovery eciency. Even if the fresh air temperature is
around the freezing point, the supply air is heated virtually to the room temperature. All profi-air ventilation units are fitted with
fully automatic summer bypass flaps, in order to prevent undesired heating of the fresh air during transitional seasons.
1.1 Introduction
These installation and operating instructions are intended to help you install a fully functional profi-air 180 flat ventilation unit and
properly operate it. We therefore recommend that you read these instructions carefully before you start to operate and set the
unit. These installation and operating instructions can also serve as a reference for service and maintenance work and guarantee
smooth and ecient operation.
1.2 Safety
If used for the intended purpose, the device is safe and reliable to operate. Its construction and design are state of the art and
comply with all relevant DIN / VDE regulations and safety provisions. All safety regulations, warnings and notes of these installa-
tion and operating instructions have to be complied with; non-compliance may result in personal injury and/or damage to profi-
air 180 flat.
1.2.1 Safety regulations
nInstallation, connection, putting into operation as well as maintenance of profi-air 180 flat may be performed by authorised
and qualified personnel only (with the exception of filter replacement).
nInstallation of profi-air 180 flat must be carried out according to applicable local construction, safety and installation regula-
tions.
nUnauthorised changes or modifications to profi-air 180 flat are not permitted.
nInstructions regarding regular filter replacement are to be strictly adhered to.
nKeep these installation and operating instructions near the ventilation unit during the entire life of profi-air 180 flat.
1.2.2 Safety equipment and measures
nThe profi-air 180 flat unit cannot be opened without tools.
nMake sure that the fans cannot be touched with hands as long as the system is connected to the power grid.
nDuring maintenance, the device may therefore be opened in the “dead” state only, and profi-air 180 flat may only be operat-
ed with the installed duct network.

1.2.2 Symbols used
1.3 Intended use
The profi-air 180 flat ventilation unit has been designed and constructed for the use in heat recovery ventilation and is solely
intended for this application. When using heat recovery ventilation, stale, moist and bad-smelling air is removed from the bath-
room, toilet, kitchen and utility rooms to be replaced with the same amount of fresh air in the living room, bedroom and chil-
dren's room. Overflow outlets provide sound and well-balanced air circulation in the housing unit.
1.4 EG conformity
The profi-air 180 flat ventilation unit bears the CE marking.
See Section 11 for EC Declaration of Conformity
Please ensure that the overflow outlets are not closed or covered in order not to impede proper function-
ing of the system.
Operation of profi-air 180 flat during the building drying stage is inappropriate in terms of its intended use.
