UNIT DESCRIPTION
The AWN Eco+ is an exhaust fan with integrated exhaust air heat pump for outdoor installation. The exhaust
fan is intended for conveying exhaust air from apartments at a constant negative pressure. The AWN Eco+
continuously adjusts its output to the existing exhaust air volume flow.
The unit includes a water-cooled heat pump that operates with R410A refrigerant in a hermetic cooling circuit
with inverter rotary piston compressor. It is a single-circuit unit with hermetic cooling circuit and inverter rotary
piston compressor, as well as a plate heat exchanger on the system side and a lamella heat exchanger on
the source side (direct evaporator). Two automatic vent valves as well as a safety valve (3.0 bar) are installed
on the sink side as standard. Microprocessor-controlled regulation including LCD display allows the heat
pump components to be operated easily via the user menu. The exhaust fan can be regulated via a separate
control unit.
TYPE PLATE
The unit is labelled with a technical type plate.
Do not modify or remove the type plate.
LOAD-BEARING CONSTRUCTION AND ERECTING DEVICE
The construction is based on a hot-dip galvanized steel frame of appropriate thickness. All other parts in
contact with the environment are made of sufficiently corrosion-resistant materials. To lift the unit, eye bolts
must be attached to the top corners of the frame. (These must be removed after installation and the remaining
openings must be closed with the enclosed cover caps.)
During the design phase, it was ensured that all interior components are easily accessible. All inner surfaces
on the exhaust side are lined with sound-absorbing material of suitable thickness.
The unit is equipped with feet which are each fitted with a base plate with two holes for
mounting fasteners. Each foot sits on a 20-mm-thick anti-vibration mat, which also pro-
tects the roof skin from damage and reduces the transmission of structure-borne noise
to the installation surface.
