1 GENERAL INFORMATION
1.1 What can be expected from the work of an EBCeasy, what can't
1.1.1 Primary purpose
The miniClima Constant Humidity Devices EBC are built for the regulation of the relative air-humidity in both
air- and steam-tight enclosed museum showcases, switchboards, deposit cupboards, containers and similar
applications (hereinafter only referred to as "cases"). The devices help in reaching and keeping a desired
level of relative air-humidity inside the cases. They are not built for the purpose of influencing or changing
any other state or condition of the air being processed (e.g. temperature, pollution, etc.), but further
equipment1 can be added to an EBC for filtering dust and particles out of the system air.
1.1.2 Characteristic features
Once set up correctly, the EBC, the case and the interconnections between EBC and case (hosepipes)
together form a tight air circulation system. As long as the EBCeasy is turned on and has adjusted its internal
air-leading parts, the air circles almost continuously through it. More in detail: The air is exhausted from the
case, led to the EBC, where it is going to be either humidified, dehumidified or left unchanged - depending on
the set and actual RH values. The conditioned air is then led back into the case. Conditioning is achieved by
means of a solid state polymer ionic membrane. On one side of the membrane it splits hydrogen ions (H+)
from the air, migrates it through the membrane and discharges it on the other side. The membrane can only
be used in one direction. Therefore the EBCeasy is equipped with a mechanism to switch the air-stream
between both sides of the membrane depending on the necessity to humidify or dehumidify. The respective
other side of the membrane is opened to the surrounding air to equalize the generated humidity level.
When the EBCeasy has to change its operation-state between humidifying, dehumidifying or just circulating,
it first stops its circulation fan, then closes flaps being open to the outside and then opens flaps according the
new operating state and starts the circulation fan again. The outside air is therefore never opened to the
internal air-stream directly. Moreover to avoid the transport of external particles into the internal air-stream,
the outside air is filtered by filter-pads of filter-class F6 on the incoming side and of filter-class F3 on the
outgoing side.
During all these times a digital sensor measures the values for relative air humidity and temperature within
the case. The EBC receives these values and compares the measured RH value with the setpoint, the

hysteresis and the threshold values, which can all be set via the menu prompts on the front panel of the
EBC.
Through the work of the EBC, the desired level of the air humidity in the case is constantly approached -
duration and speed depending on the initial values, on the conditions (temperature, humidity) the case is
exposed to, and on a number of further variables (like the temperature at the EBC's place of installation, the
size and shape of the case, the air/steam tightness of the case, the kind of materials stored inside the case,
the length of the hosepipes, whether or not the hosepipes are laid in many bends and turns etc). After the
setpoint range (=setpoint +/- hysteresis) has been reached, the RH is going to be kept on a constant level. A
negligible movement around the setpoint might be observed. This behaviour is technically induced and does
not constitute an error.
A typical reaction process can be seen in the following picture, showing the humidification and
dehumidification by an EBCeasy1 for a showcase of 1,0m³ (RH: blue, T: red) at 30%RH, 22°C surrounding
conditions.

1.2 Risk of use, recommendations
Our devices are first and foremost used for the regulation of the relative humidity of the air surrounding
precious and/or irreplaceable works of art or artefacts. It is therefore necessary to cover all possible
imponderables, when installing and using the EBCs. For this purpose, please do bear in mind the following
recommendations and risks of use.
A clean installation, carried out according to the instructions found in this manual, is the basis for a working
system. In particular essential are:
The use of a climate-ready case (air-tight, steam-tight).
The positioning of the miniClima RH/T sensor on a spot that features the same environmental conditions
as the one where the exhibit is placed (see section 3.2.3 "RH/T sensor", p. 1 ).
The design and positions of the air inlets and outlets on the case (see section 3.1 "Setting up the EBC,
establishing the hosepipe connections", p. 10).
That the air resistance within the air circuit is kept low (short hosepipe connections, avoidance of too
many bends and turns when laying the hosepipes etc. - see section 3.1 "Setting up the EBC, establishing
the hosepipe connections", p. 10).
Preventing different temperatures inside the case (light installations, solar radiation,...). The miniClima
RH/T sensor and the exhibit in particular need to be exposed to the very same temperature.
The temperature surrounding the EBC and the hosepipes (see section 3.1 "Setting up the EBC,

establishing the hosepipe connections", p. 10).
Regular visual inspection of the EBCs, regular maintenance and care of the EBCs (see section 7
"Maintenance and care", p. 38).
We recommend a beforehand verification by the user/customer that our product is going to be able to fulfil
the individual expectations and needs required for the specific case. Please don't hesitate to get in touch for
any questions.
It is further recommended to test the function of a completely installed system (consisting of the case, the
interconnections and the EBC(s)) before using it to control the relative air-humidity of sensitive exhibits or
components. In doing so, possible errors (i.e. wrong installations) can be discovered early enough to have
them corrected.
Please bear in mind that every technical device can break. So, to be on the safe side with respect to the
lasting integrity of your sensitive and valuable exhibits or components, further actions should be considered:
Regular inspections of the case and the EBC through skilled personnel probably provide for the highest
possible safety against technical failures or breakdowns.
Installation of external signal devices for every EBC, to be alarmed in time when one of our devices
needs attention (see section 3.2.5 "Wirings for the external signals (Composite error alarm and on-off
status)" on p. 16).
Having a spare unit at hand if need be or when the regular inspection at our workshop becomes due. You
can save time and avoid delays during which your case might remain without humidity control. Those who
decide for this option should actually best have their EBCs rotate in regular intervals.
Please mind to install, use, maintain, deinstall, pack up, store and ship your EBC and all accessories
correctly and in accordance to the instructions.
1.3 ermissible ambient conditions
-5 - 30°C, 15-80%RH, non-condensing (applies to the storage of the EBC as well as to the operation of
the completely installed system as a whole).
Note: The performance ot the EBCeasy also depends on the humidity of its environment, as a high
difference of the humidity inside and outside of the showcase can cause diffusion of humidity through the

membrane.
NOTE: The values -5 - 30°C and 15-80%RH refer to the air-conditions surrounding the EBC and the case
which are generally obligatory for operation (or damage-free storage) of the EBC. They do not refer to the
surrounding air-conditions were the full capacity with respect to the achievable setpoint range (inside the
case) will be given (see also section 9 "Technical data", p. 0).
1.4 Further requirements for using EBCs
The EBCeasy has to be operated with 12V DC, 2 W. An according wall power supply is usually part of
delivery.
1.5 Available types
EBCeasy-1 device for air volumes of up to approx. 1,0m3.
EBCeasy-2 device for air volumes of up to approx. 2,0m3.
NOTE: The capacity of an EBC will differ depending on the ambient conditions, the tightness and
constitution of the case, the tightness and constitution of the connections between case and device, the kind
and consistency of the materials stored/presented inside the case, and the like.
Every EBC of the current series can be used as both a master unit and a slave. The decision for one of the
two hierarchic states is selected automatically dependant upon the type of cable connected to the EBC. If it
is the cable of a miniClima RH/T sensor then the EBC becomes a master controller; if it is the control line
coming from another EBC then the unit becomes a slave and will duplicate the function of the EBC that is the
first in the line (chain of EBCs).
With this it is possible to increase the max. volume of the air that can be conditioned: Every added
EBCeasy1/2 increases the capacity by approx. 1,0/2,0m3.

3 INSTALLATION
3.1 Setting up the EBC, establishing the hosepipe connections
NOTE: If you have ordered air-distribution-boxes (LVB20), filter boxes, or other accessories relevant for
the hosepipe connections, do also regard their additional installation manuals at this point.
The EBC should be positioned as close as possible to the case, to keep the air resistance, which increases
with the length of the used hosepipes, low. The EBC should not be located in the air-conditioned part of the
case itself. The device has to be installed horizontally and firm. The device has to be given the possibility to
emit its self-produced heat during the operation. It is therefore necessary to ensure, that…
1) ...the device's place of installation (mostly the plinth of the case) is aired (e.g. by means of ventilation
holes in the plinth , or by ventilation fans, if necessary);
2) ...the EBC is placed on a plain surface
3) ... the filter grills on the sides are not blocked and that edge distances of min. 10mm (right side, left side)
are kept for an adequate ventilation;
) ...the air slits are vacuum cleaned regularly, if necessary, and the filter(s) behind the air grill(s) on the right
Recommended sizes and positions for the ventilation holes: 2x50cm2 per EBCeasy: top & bottom panel of the plinth and/or both side panels of it.
