Saftey instructions
For safety it is absolutely necessary that the following instructions are thoroughly read and
observed.
Receipt
The consignment contains:
KWL EC 300 Eco with control panel
Please check delivery immediately on receipt for accuracy and damage. If damaged, please
notify carrier immediately. Delayed notification may void any possible claim.
Storage
When storing for a prolonged time the following steps are to be taken to avoid damaging
influences: protection by dry air and dustproof packing (plastic bags with drying agent and
moisture indicators). The storage area must be free of water, vibration and temperature
variations.
When storing for years or non rotation of motor an inspection of the bearings with possible
replacement and an installation inspection in accordance with VDE 0530 are necessary
before starting using the unit. Damage caused by incorrect storage, transportation or
installation are not valid warranty claims.
Operation Use
Compact unit to use in dry indoor areas for ventilation with heat recovery. Suitable as central
or decentral solution for commercial or industrial applications. The standard equipment
permits the installation and use in frost-protected rooms up to +5 °C.
For operation under difficult conditions, e.g. high humidity, long periods of standstill, high
air pollution or through climatic, technical or electronic influences other than standard
operations may not be suitable. For this reason please enquire and obtain operation release.
A release by a third party is not valid.
Mode of action
In the heat exchanger the cold outside air and the warm extracted air "crosses over" without
touching. Through this exchange the energy of the warm air (>90 %) is tranfered to the
incoming air. Additionally a thermostat controlled heating element (pre-heating) warms up
the inlet air (in extreme cold weather conditions) to the required temperature. The inlet air
is directed to the living rooms and bedrooms through ducting and valves. The used air is
extracted from the bathrooms, toilets and kitchens. It flows back to the fan via the ducting
systems, transfering heat before being released into the open air.
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 300 Eco 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.
