Important informations
Operation: Important information about the ventilation system as well as settings at the
controller are specified here.
Maintenance: In the maintenance part important information about filter changes and necessary
cleaning and maintenance activities are specified. The user usually accomplishes maintenance
work.
Montage: The chapter “installation” with important installation information and unit base
settings addresses itself to professional installers. Read this instruction in any case carefully
and completely before you operate, install or connect the ventilation unit. Keep in safe
custody!
Planning documents: The planning office provides the necessary planning documents for the
system calculation. Additional information can be requested ex works.
Saftey instructions
For safety it is absolutely necessary that the following instructions are thoroughly read and
observed.
Receipt
The consignment contains: KWL EC 200 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 200 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.
3
GENERAL INFORMATIONS
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
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.
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.
m 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.

FUNCTIONS
Models: KWL EC 200 Eco R / KWL EC 200 Eco L
KWL EC 200 Eco removes contaminated air and replaces it with fresh filtered and heated
outdoor
air.
Efficient filtering of outdoor air (G4 + F7) prevents harmful particles from entering the duct­
work and rooms via the unit. Good filtering of extract air (G4) diminishes the contamination
of the unit and ensures proper operation of heat recovery and the extract air fans.
With an effective counter-current heat exchanger, most of the heat of contaminated extract
air can be transmitted to outdoor air coming inside. The efficiency of KWL EC 200 Eco
depends on the temperature of extract and outdoor air, the humidity content of extract and
outdoor air and the air flow volume of extract and supply air. The adjacent examples show
the efficiency of supply air in KWL EC 200 Eco in two different sets of circumstances.
The unit has a manual heat recovery bypass function, which eliminates needless heating of
outdoor air during summer. The automatic defrosting of the heat recovery cells intermittently
stops the supply air fan when the temperature of exhaust air goes under the set threshold
value.
The unit KWL EC 200 Eco has an 4-level operation switch and therefore four speed steps.

1
• The unit is mounted indoors, in a place where temperature does not fall below +5 °C.
• If installed within not heated areas (e.g. cock loft) a sufficient isolation on all sides is to be
mounted outside at the unit. Otherwise condensate formation at the casing sides could
occur. The condensate drainage must be laid frost protected.
• The unit is to be mounted in a place where the sound pressure level coming through the
envelope is not acoustically disturbing (utility room, washroom, corridors, technical rooms,
stores, and in some cases rooms where people spend time).
• The unit is mounted on the wall using the wall mounting plate included in the delivery.
Lift the unit to the wall making sure that the hooks on the back side of the unit attach to
the mounting plate.
• The unit is splash protected (IP34), and can thus also be mounted in a damp room.
• NOTE: Remove the transportation lock (wingnut) in the extract duct.
• Before start-up, check the rubber aprons of the motors. They must be fitted correctly.
• NOTE: The unit has to be mounted level with the vertical and the horizontal. (indispensable
for a correctly condensat drain).
Duct connections
• The unit has four (diameter125) inner fittings equipped with rubber rings. Fix the ducts
steadily and tightly to the outlets. (NOTE! Unit models L/R). Implement insulation as defined in
the ventilation plan.
Condensing water connection
• Water condensing from extract air going through the unit is removed from the bottom
reservoir through a condensing water outlet.
• Condensing water is led through the outlet either to a floor drain or to the wastewater
drain. The connection is to be located before the water seal.
• The drain must not rise after the water seal.
• The condensing water outlet is placed in the middle of the unit. The unit must be installed
100 % perpendicular (very important for a correct condensing water drain).

FUNCTIONS
2. Function
The differential pressure switch DDS monitors the pre-installed outside air filter G4 and the
optional usable pollen filter F7 (intake air). It monitors the static pressure loss between out­
side air and intake air duct.
If the air flow volume is reduced due to dirty. filters,
the pressure loss decreases between the
.
two measuring points ( In the extreme case at V=0 Þ Dp=P1-P2=0 ).
A filter signal, for example a signal lamp can be build on site.
3. Adjustment
The following conditions must be fulfilled:
.
1. The system is installed and
. air flow volume V is set.
2. Switch position of DDS on 3/1 (see wiring diagram SS-857.1, page 10).
3. Set KWL EC 200 Eco unit on middle speed step.
Turn adjustment knob at the DDS (+/-) until switching point responds. Now read the switching
point and reduce by approx. 15% (e.g. 100 Pa Þ setpoint 85 Pa). As soon as the pressure
drops below 85 Pa, the filter signal (build on site) control responds.
Bypass function
Adjustment is carried out via mechanical bypass flap. Open or closed manually. The outside
air is passed by the counter flow heat exchanger at 100% and thus the heat recovery is
stopped.
Defrost function of heat recovery cell
To protect the heat recovery cells from freezing, the supply air fan was switch off temporary
by the measured data of the frost protection sensor.
Maintenance display
Adjustment and control is effected via differential pressure switch DDS (see wiring SS-857.1).
The differential pressure switch DDS is a complete kit to monitor air filter, system pressure
and fan operation. The filter state is indicated over a signal lamp (build on site). In that case
the filters must be cleaned or exchanged.

ATTENTION: All work only in dead state! Before maintenance 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.
G
Filter and heat recovery cell
• When the Maintenance reminder turns on the indicator
lamp in the 4-level operation switch, check the filters.
Outdoor air is filtered in the unit with two separate filters.
A coarse filter (A) of class G4 filters off insects, rough pollen
and other dust. A fine filter (B) of class F7 filters off invisible
dust. Extract air is filtered with a filter (C) of class G4.
• Clean the coarse filters (A and C) by washing them at least
twice a year.
• When you open the door of KWL EC 200 Eco, the security
switch turns voltage off. Filters can now be pulled out.
Wash the coarse filters with +25…30 °C warm water and
washingup liquid, pressing them smoothly. Do not handle
the filters with force. When washing is done properly, filters
stand cleaning 4…5 times. In other words, you have to
replace them at least every years or when needed.
• The fine filter is not washable. Clean it at the same time as
the coarse filters, using the brush nozzle of a vacuum clea­
ner. When cleaning, be careful no to break filter material.
To ensure good supply air quality, replace the filter at least
once a year or more often, depending on local air quality.
It is recommended to replace filters in the autumn. This
way the filters stay cleaner through the winter and can ef­
fectively filter off dust in the following spring.
Filters can be ordered via internet: www.ersatzluftfilter.de

E
• IIt is also recommended to check the cleanliness of the cross-counter heat exchanger in
connection with filters about every 2-years. Handle the thin fins carefully, because they
could bend easily. If the exchanger is contaminated, soak it in a solution of water. Rinse
the exchanger with a jet of water. Pay attention, that no wetness remains inside of the
cross-counter heat exchanger before installation. If the cell is contaminated, soak it in a
solution of water and washing up liquid. Rinse the cell clean with a jet of water.
When all the water has drained from between the laminas, put the cell back in place. Lift
the cell while pushing it in place. For this pull out the sealing strip. Lift and push at the
same time the exchanger and place it on the sealings below. Insert sealing strip again and
check fit of sealing.
Fans
• Check the fans at least every year of pollution or if necessary clean them. Use a small
brush an cathartic against rich. Take care! Do not let water flow to the motor parts.
Dry the fans before mounted them into the unit!
• The supply and extract air fans (E and F) have been fastened with rubber collars. When
removing the fans for maintenance, release the ear fixed to the fan over the collar flange
by bending it upwards. Remove the rubber collar from the opening and turn the fan so
that it can be removed. Remove the plug behind the fan. Clean the fan blades with
compressed air or with brush. Each blade has to be so clean that the fans stay balanced.
Take care not to remove the balancing pieces attached to the fan blade.
• If you use water in cleaning, do not let it flow to the electrical parts.
Condsensing water outlets
• During the heating season, humidity of extract air condenses to water. Water formation
can be abundant in new buildings, during baths and when wet clothes are being aired.
• Condensing water needs to flow out from the ventilation unit without hindrance. In
connection with maintenance, e.g. in the autumn before the beginning of the heating
season, make sure that the condensing water outlet in the bottom reservoir is not clogged.
You may check it by pouring a little water in the reservoir. Do not let water flow to the
electrical parts.
