GENERAL INFORMATIONS
Performance
To achieve the given performance, the unit must be correctly installed. Varying from the
design and/or installation requireements and also by incorrect operation can lead to a
reduction in the unit capacity. Noise figures are stated in sound power levels LWA in dB(A)
(conforms to DIN 44635 T.1). Sound pressure levels LPA depend on room specific conditions.
These conditions may affect the measured result on site and vary from the catalogue data.
Installation – Assembly
The KWL EC/ET 200 Pro is suitable for „hanging“ arrangement for installation in a cupboard
or for installation on a wall and therfore for installation within the room of the dewelling.
There are drilled holes for wall installation at the level of the air connecions. For wall
installation a support plate to hang the unit on is included. If a wall installation is not possible,
the unit can also be fixed through its side panell into the ajoining surface.
When screwing through the side panel, the fans, controler, heating element and electrical
wiring must not be damaged or restricted in function. Sound and vibration transfer must be
considered on site when installing the unit.
It is necessary to connect the condensation spigot of the unit to a pipe connected to the
Kondensatablauf
drainage system of the house with a U bend trap in to prevent oders returning from the
drains (see condensation run-off). The condensate pipeing must ensure the effective gravity
flow of the condensate water. Tight bends can lead to a high pressure loss and flow noise. Condensing water outlet
A secure and tight connection of the ductwork is required. For maintenance and installation
work, the unit must be accessable.
When taking the unit out of the carboard box, the unit must not be stod on the condensation
spigot at the bottom of the unit. Therefore lay it on its back to prevent damage, using the
polystyrene packing to lay the unit on will ensure the unit will not get scratched. Before
installation the operation switch must be taken out of the unit.
Fireplaces
Fire and building regulations must be observed.

Elektrical connections
ATTENTION: Only work with the unit isolated from the electric supply!
Electrical connection is to be carried out only by a qualified electrician, observing the
appropriate regulations and guidelines of national bodies and the EVU (e.g. VDE 0100/
DIN57100 T.420) VDE0721, DIN18379). Before maintenace an isolator is required for
with a minimum of 3 mm contact opening of each pole. Electrical connection should only
be carried out by a qualified person.
Electrical connections are to be made according to wiring diagram in these instructions.
Connection in the external terminal box in accordance with the wiring diagram.
Ventilation duct, ventilation line
When designing the ductwork, use the shortest possible runs. Airight connections and change
overs must be ensured for the best possible heat recovery. To avoid pressure loss, accumulating
dirt, and noise, use smooth ducting (plastic or rigid ducting). For main ducting (outside air,
extract air, inlet air, discharge collection) a diameter 160 mm has to be used, for side ducting
the diameter ø must be suited reduced.
To reduce condensation in the extract and outside air pipes, the ducting has to be insulated
where appropriate. Also if inlet and extract ductwork cross unheated rooms insulation must
be provided to reduce heat losses.
Fresh air should be supplied into living and bedrooms, extraction takes place in bathrooms,
toilets and kitchens. To balance the whole system the duct connection into the rooms we
recommend the use of adjustable valves.
On extract of polluted outside air a filter (accessory) is to be used. It is not allowed to install
kitchen hoods to the system (dirt, fire, hygiene). There must be enough air transfer flow
between rooms (e.g. door grilles) within the building to guarantee air flow between intake
rooms and extract rooms.
IMPORTANT: Fire and building regulations must be observed.
