1 GENERAL INFORMATION
1.1 What can be expected from the work of an EBC, 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 EBC is turned on, the air circles continuously
through these three parts of the system. 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. 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 - the higher the setpoint the more distinct. This
behaviour is technically induced and does not constitute an error.

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 3.3.2 "RH/T sensor", p. 19).
The design and positions of the air inlets and outlets on the case (see section 3.2 "Setting up the EBC,
establishing the hosepipe connections", p. 12).
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 3.2 "Setting up the EBC, establishing
the hosepipe connections", p. 12).
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 3.2 "Setting up the EBC,
establishing the hosepipe connections", p. 12).
Regular visual inspection of the EBCs, regular maintenance and care of the EBCs (see section 7
"Maintenance and care", p. 7).
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 3.3. "Wirings for the external signals (Composite error alarm and on-off
status)" on p. 20).
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
5-35°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).
10-50ºC, 20-60%RH, non-condensing (applies to the storage of the RH/T sensor).
NOTE: The values 5-35°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. 53).
1.4 Further requirements for using EBCs
Electric supply through a fuse-protected standard socket-outlet with earthing contact. Possible range of
voltage & frequency: 100-2 0VAC, 50-60Hz.
No pipework is required for the use of an EBC (all water is taken from and stored in the unit's own bottle).
1.5 Available types
EBC10 - device for air volumes of up to approx. 3m3.
EBC11 - device for air volumes of up to approx. 5m3.

EBC12 - device for air volumes of up to approx. 10m3.
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 EBC10
increases the capacity by approx. 3m3, every added EBC11 by about 5m3 and every added EBC12 by about
10m3. Mixing different types of EBCs (EBC10, EBC11, EBC12) within one chain is permissible. Furthermore
it does not matter which of those types is going to be used as the master of the chain and which as slave(s).

Your EBC can be equipped with a standard fan (ULV) or with one of the stronger fans (ULV+ and ULV++).
The latter are used with units that shall work in installations with an increased air resistance inside the air
circuit system. The fan type built into the unit is marked on the EBC's rating plate. (see Fig. 1).
2.7 Identifying the kind and number of the water level sensors for the bottle
By default every EBC is equipped with one water level sensor for the bottle high mark. Once the bottle
becomes full, the sensor provides for the respective alarm to be issued. The devices can optionally also be
ordered to be equipped with a second sensor for the low mark of the bottle, so that the user can be alarmed

before the bottle becomes empty, too. Where neither of these alarms is required both sensors can be left
away and the EBC will be delivered without any bottle alarm.
The bottle sensors are turquoise rectangular plates mounted to aluminium brackets on the side (default for
EBC10 and -11) or front (option for EBC 10 and -11; by default the only option for EBC128) of the EBC (see
Fig. 3). The top bracket also holds the black hook-and-loop-fastener ("Velcro®") for securing the bottle. If you
see a sensor on the top bracket, your unit is equipped with a water level sensor that issues an alarm before
the bottle can overflow. If you see a second aluminium bracket with a turquoise sensor below, your unit will
also recognise it when the bottle needs to be refilled.
Fig. 3 - Water level sensors for the high and for the
low level alarm. In the sample image, the brackets,
that hold the sensors and the hook-and-loop-fastener
for securing the bottle, are mounted to the left side of
an EBC10 or -11. They can also be mounted to the
front of any EBC10 or -11, whereas on EBC12 they
are always positioned on the front plate; if you need
to have them mounted to the side of an EBC12
additional parts need to be ordered for that purpose.
3 INSTALLATION
3.1 ositioning the bottle
The bottle (0.5l or 2.0l) can be positioned to the left of the EBC10/11 as well as to the front of it (EBC12: By
default to the front only, with optional accessories to the side as well). By default the bottle holder(s) with the
water level sensor(s) (if any; see section 2.7 "Identifying the kind and number of the water level sensors" on
p. 9) and the hook-and-loop-fastener for securing the bottle are mounted on the side of any EBC10/11. If that
assembly shall not be changed, continue with section 3.2 "Setting up the EBC, establishing the hosepipe
connections" on p. 12.
If, on the other hand, you plan to put the bottle (0.5l or 2.0l) to the front of your EBC10 or -11, follow these
steps:
8Additional parts for mounting the bottle holder to the side of an EBC12 are available.

- or anyway, laid in a way so that the bottle will still touch the sensor, once fixed with the hook-and-loop-
fastener):
Rearranging the holders back to the left side of the EBC is done likewise.
 IM ORTANT: Beware to not squeeze any cable or the silicone pipe when rearranging the holders! Also, do
not yet fill the bottle. Please continue with the installation as follows.
3.2 Setting up the EBC, establishing the hosepipe connections
NOTE: If you have ordered air-distribution-boxes (LVB25, LVB32, LVB 0), filter capsules (FLT25, FLT32,
FLT 0), 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, though9. The device has to be installed horizontally and firm in order to permit correct water level
control, and to avoid water running out of the inner evaporation tub during operation. 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 plinth10, or by ventilation fans, if necessary);
2) ...the EBC is placed on a plain surface (no carpets or other materials that could block the cooling air slits
on the bottom of the EBC);
9Users do report that this has been done successfully, still, we do not recommend it. If you intend to place your EBC inside the conditioned part of your case, you should be
aware of the fact that the EBC has to and will emit its self-produced heat. Furthermore you will have to take care against a shortcut of the air flow between the EBC's air inlet
and outlet, which are very close to each other. Finally it would become necessary to open the conditioned part of the showcase every time the EBC has to be handled
(filling/emptying the bottle, changing settings or reading out data via the menu, connecting a PC to the EBC, maintaining the cooling air slits/grills/filter,...).
10 Recommended sizes and positions for the ventilation holes: 2x150cm 2 per EBC10 or -11, x150cm2 per EBC12; top & bottom panel of the plinth and/or both side panels of it.

3) ...neither the cooling air grill on the right side (EBC10/11/12), nor the one on the left side (EBC12 only),
nor any of the slits (top, bottom) are blocked in any other fashion and that edge distances of min. 50mm
(EBC10/11: top, right side; EBC12: top, right side, left side) are kept for an adequate ventilation;
) ...the air slits (top, bottom) are vacuum cleaned regularly and the dust filter(s) behind the air grill(s) on the
right and/or left side are regularly checked/vacuum cleaned/washed/replaced (see section 7
"Maintenance and care", p. 7).
 CAUTION: Absence of ventilation at the device's place of installation or blocked cooling air in-/outlets of
the device might overheat the device, as well as reduce the dehumidification capacity of the device.
Two hosepipe connections for the air circulation have to be established between each EBC and the case.
Follow the steps described below for each device that shall be connected to the case (includ. every slave
unit, if any):
The device itself is already equipped with two hosepipe fittings. The hosepipe fittings on the case wall need
to be affixed now. You need two hosepipe fittings for every EBC - one for the air inlet, one for the air outlet.
Firstly define the ideal positions of the air in-/outlets on the case so as to best enable an equal distribution of
the conditioned air.
NOTE: The positions shown in Fig. do not represent a general solution or recommendation.
Mind the following rules before deciding:
1) As already mentioned above, all used EBCs should be positioned as close as possible to their respective
cases, though they can also be placed some meters away, if necessary. Due to the growing air resistance
the efficiency of the EBCs diminishes a little with the length of the tubes. Mind the total length of the
hosepipe provided with your EBC.
2) The hoses must not be laid next to heat-emitting parts.
3) In- and outlets (even those of different EBCs) must not be located directly next to each other on the case
wall (you may position inlets next to inlets and outlets next to outlets). If they need to be positioned close
to each other, anyway, the inner construction of the case should be realised along the ideas presented in
Fig. .
) The constructions on the inside of the case should be realised in a way that enables the air to stream
over the whole volume of the case. Should i.e. some air in- and outlets be located behind the same
partition wall or divider, the inlets need to be sealed off from the outlets even if much space is left

between those in- and outlets - see Fig. .
5) For partition walls / dividers / sealed off separations between in- and outlets: The overall surface of the
openings between each partition / separated part and the rest of the case should at least be of the same
size as the sum of the cross-sections of all hosepipes connected to this partition / separated part, thus
ensuring that the air does not need to overcome a higher air resistance there than it does inside the
hosepipes.
6) There is no universally valid figure for the permissible max. total length of the hosepipe connections per
air circuit between EBC and case but the length that is usually delivered with a device (3, 5 resp. 6m) can
be taken as a reference.
Fig. - The shown positions of the hose fittings do not represent a general solution or
recommendation.
As soon as the positions are fixed, you need to clarify whether the thickness of the case walls exceeds 6mm
on those positions where you want to bring on the hosepipe fittings. If the thickness is 6mm or less you may
cut, drill, or crack the holes for the hosepipe fittings directly in the case wall11: EBC10: Ø 25mm, EBC11: Ø
32mm, EBC12: Ø 0mm. If the thickness is above 6mm on the other hand, you need to use intermediate
pieces (not part of the delivery by default) whose thicknesses actually are max. 6mm, e.g. metal plates like
our flanges. The necessary diameters for the boreholes when using flanges or the like result from the size of
the counter nut and gasket of the respective hosepipe fitting: VE25.. (EBC10): Ø 37- 2.5mm; VE32..
(EBC11): Ø 2- 9mm; VE 0.. (EBC12): Ø 5 -60mm (always depending on the make of the counter nut -
please take measurements on the delivered parts.)
 IM ORTANT: Mind the necessity that every air in-/outlet on the case has to be carried out airtight.
Hosepipe fittings, which are fitted directly to the case wall with the delivered gasket, need no further sealing.
For intermediate pieces that come without gaskets the additional use of silicone will be required.
11 Mind that purpose-made models might be equipped differently. Always measure off the delivered parts before cutting/drilling/cracking. Also, EBCs that shall be used together
with LVBs will need different boreholes on the case walls - see the delivered installation manual for the LVBs.

3.2.1 Handling the hosepipe fittings
Currently three different types are in use: VE.._V1 (partly discontinued) and VE.._V2 are both for use along
to our robust PVC hosepipes UFX.._V1. The newest model is VE.._V3. It is now the standard fitting used on
new builds and fits to our PA wave tube UFX.._V2. The gaskets (GD..) used along to all these fittings are
always of the same type.
3.2.1.1 Handling VE25_V1, VE32_V1 and VE 0_V1
1) Slide the union nut (A) over the hosepipe (F). Then, press or "screw" the clamping ring (B) over the end of
the hosepipe:
2) The screw joint (C), the rubber gasket (D) and the counter nut (E) have to be brought into either the case
wall or the intermediate piece/flange (G) (ensure this connection to be tight):
3) Finally, push the hosepipe with the clamping ring in the screw joint and fix the connection with the union
nut (again making sure that this connection is tight):

3.2.1.2 Handling VE25_V2, VE32_V2 and VE 0_V2
Handling the second model is almost identical: The slotted clamping ring is now built into the joint screw as
slats. Please do take good care to not fold over these slats as well as to position the hosepipe inside all of
the slats when inserting it into the joint screw. Always cut the hosepipe as even as possible, in order to make
it possible for the hosepipe to be seated solidly inside the screw joint (relevant for the tightness). We
recommend the use of appropriate hosepipe nippers.
Furthermore, please do always push the hosepipe up to the stop inside the joint screw. Fix the connection by
use of the union nut only when the pipe has been pushed fully inside. The union nut should be tied up well
but do not over-tighten it.
Proceed like this:
1) Slide the union nut (A) over the hosepipe (E):
2) The joint screw (B), the rubber gasket (C) and the counter nut (D) have to be brought into either the case
wall or (as seen here) into the intermediate piece/flange (F) (ensure this connection to be tight):
3) Finally, push the hosepipe up to the stop inside the joint screw and do fix the connection after that with
the union nut. The union nut should be tied up well but beware to not over-tighten it.  IM ORTANT: All
slats of the joint screw have to remain outside the hosepipe, do not fold them over:

3.2.1.3 Handling VE25_V3, VE32_V3 and VE 0_V3
Handling these fittings is somewhat different as compared to the way the two other models are operated,
whereat the new fittings offer significant advantages:
It is by far easier to establish an air-tight connection between hosepipe and connector.
Less effort is required for affixing the hosepipe in the connector (no clamping ring, no union nut).
The only downside of the new parts can immediately be spotted as their most prominent distinction: The
necessity of tools or means of aid for loosening the connection once the hosepipes have been put inside the
connectors. A suiting tool (VEOPENER) will of course always be part of our deliveries. No tools are required,
on the other hand, for the establishment of the connection of hosepipe and connector.
The handling in detail:
1) Again, cut the hosepipe as straight and even as possible. We recommend the use of nippers built for that
purpose (can be ordered with us).
2) Also like above (see there), the connectors have to be affixed to either the showcase wall or to an
intermediate piece/flange using the rubber gasket and the counter nut (make sure that this connection is
air-tight).
3) Finally, simply press the delivered hosepipe into the connector until it stops. Have the fixing clips of the
connector closed while doing so. There is no need to open them up in the beginning. There is also no
need for the use of any tools for this process.

) Use a tool (i.e. a screw driver or the one originally delivered by us) for opening up the connection again.
Push the latches on both sides to the outside in order to do so:
3.2.2 Connecting the hosepipes to the EBC
Dispose of the protective coverings on the hosepipe fittings of the EBC, if any. After that, proceed as
described above in order to attach the hosepipes to the EBC's fittings. Mind the different types of fittings
mentioned above.
3.3 Electrical connections
3.3.1 Handling the ferrite core
In case you need to take off the ferrite core(s) of the RH/T sensor cable or the control line temporarily, this
can be done easily (kind and colours of the cores vary):

 IM ORTANT: Do not forget to put the core(s) back on the cable before using the EBC: Wind the cable
through each core once - see the pictures above. The core(s) should be positioned next to the RJ 5 plug of
the sensor cable or next to each of the RJ 5 plugs of the control line respectively.
3.3.2 RH/T sensor
(Applies to EBCs used as master units only.)
Please see the printed note that has been added your delivery before handling the sensor.
 IM ORTANT: The RH/T sensor has to be affixed at a suitable point inside the case, which ideally is in the
close surrounding of the humidity sensitive objects stored/presented in the case. The sensor does not
necessarily have to be placed in the visible part of the case, but even so, it has to be positioned on a spot
and under conditions that are comparable to those of the exhibit in the case. Especially lighting installations
and their effect on the temperature of the air surrounding the sensor may have a heavy impact on the
functioning of a correct humidity control. Do not cover, wrap, or in any other fashion separate the sensor from
the air that surrounds the exhibit.
By default the sensor comes complete with housing, a 2.5m or 5m cable, a RJ 5 plug and a ferrite core. As
neither all parts of the sensor housing nor the plug can be detached from the cable, you need a borehole of
min. Ø 13mm in the case wall so as to be able to lead the cable (sensor sided) through.  IM ORTANT: The
chip of sensor is an easily damageable electronic component and it juts out a bit from the housing. Therefore
it is important to take good care to not harm it when leading it through the wall! It is also essential to take
care for an airtight lead-through of the sensor cable through the wall of the case.
Once the sensor is positioned and mounted inside the case, verify that the EBC is still not plugged to the
mains connection. Then plug the sensor cable to its jack on the front plate of your EBC, labelled Sensor &
Control in. With the sensor plugged in, the EBC is already defined to be a master unit.
 IM ORTANT: Do not plug or unplug the sensor to/from the EBC during operation! Always turn the EBC off,

wait for the completion of the pumping process (if any) and then pull the mains connection before handling
the sensor cable. Otherwise the electronics of the EBC might be harmed and/or unexpected malfunctions
might occur.
3.3.3 Control lines
(Applies to master/slave-systems only.)
 IM ORTANT: Do not plug or unplug the control line to/from any affected EBC master or slave set as long
as they are operating! Always turn the master off (all slaves follow automatically), wait for the completion of
the pumping process (if any) and then and pull the mains connection cables of the affected EBCs before
handling the control line(s) interconnecting the EBCs. Otherwise the electronics of the EBCs might be
harmed and/or unexpected malfunctions might occur.
Every EBC that is ordered as a slave unit is going to be delivered with a 2m or 5m control line - a customary
category-5e patch cable, twisted pair/non-crossed, with RJ 5 plugs and ferrite cores on either end. Verify all
EBCs are still not plugged to the mains connection, then plug one RJ 5 to the master unit's jack labelled
Control out and the other to Sensor & Control in on your slave. In case two or more slave units shall be
controlled by one master unit, continue by always leading the control lines from Control out of the
first/previous slave unit to Sensor & Control in of the following one.
3.3. Wirings for the external signals (Composite error alarm and on-off status)
Every miniClima Constant Humidity Device is equipped with two potential-free changeover contacts that can
be used for the installation of external signals, i.e. red/green lights in a control room, or sirens. One signal
indicates whether the EBC is turned on or off, the other switches whenever the EBC issues an alarm.
 CAUTION: Max. voltage/amperage for using of the changeover contacts: 8V/ A.
The wires that shall be connected to the changeover contacts of the EBC have to be put to the EBC's 6pin
plug-in connector. Proceed as follows for handling the plug-in connector:
1) Grip the plug-in connector on its sides with index and thumb and pull it off from its connection plug. Hold
the EBC with your free hand when doing so, to keep it from being torn away ( IM ORTANT: The
connector has to be pulled off the EBC for all works that shall be done on it):
Applies analogously to the individual products of series EBC10/11/12 (Rev.3). As of 2 .11.201 . Subject
