Information about the device
Device description
The Qube+ consists of only one device and is 50% lighter and
50% smaller than a comparable MultiQube tower.
A multi-device installation with complex hose connections can
be omitted without replacement. Just set it up, plug it in, switch
it on – all done! No further equipment technology is required.
The device comes ready for connection with all integrated parts:
a powerful fan motor, a water separator, a 4-stage filter system
and an efficient silencer – ultra-compact, united in a robust,
stackable aluminium construction, offering clearly more
advantages and at the same time causing considerably less
costs than multi-device solutions.
Globally unique integral solution:
• VX 5 turbine
• Water separator WA 4i
• HEPA filter module
• Silencer NR 19
Equipment features:
• Adaptronic power control for flexible low-pressure surface
drying operations ranging from 8m2 to 85m2
• Globally unique HiDry automatism for all power stages
• Optiflow NT multi-function display
• Non-wearing touchscreen control panel
• Counter for operating hours and energy consumption
(MID-compliant)
• Night operation – whisper mode
• 2 TTKwic quick couplings for drainage connection of
dehumidifiers
• Flexible 4-stage filter system
• DA4 interface
• Efidry humidity sensor connection
• Residual water draining
• Connection for discharge of hot process air
• Service socket (tamper-proof)
• Cable holder
• Key lock to prevent maloperation
• ECO level (stage1) for small surfaces
• Height-adjustable telescopic push handle
The device is equipped with a touch screen with LC display.
It provides information on the operating stage, air flow rate etc.
The background colour of the LC display changes according to
the traffic light principle to indicate how suitable your drying
installation is. An optimal air flow rate is indicated by a green
background colour during operation. If the display is illuminated
in yellow, this means that the installation is OK but the flow
conditions for the dry air are not optimal. Drying can be carried
out without any difficulties while the display is yellow. A red
background indicates an uneconomic operation. The
compressor should not be permanently operated in this
condition.
Practical benefits:
• The most light, compact and powerful system unit on the
market
• 50% smaller than a comparable MultiQube installation, up
to 75% smaller than constructions from competitors
• Flexible filter system with optional HEPA filter usage
• Total weight only 27kg
• Stackable
With the device all negative time factors can be eliminated in
one sweep – this way less devices are needed and moved,
stock requirements are reduced, more equipment can be
transported to the damage site per tour, less time is needed for
set-up and disassembly as well as for cleaning. All in all, your
working, space and warehouse productivity can be increased
many times over by using the Qube+!

Connecting the drain hose
The device must be connected to an appropriate drain or
collection container via a drain hose so that the device can drain
the accumulated water from the water tank if required.
Observe the following when connecting the drain hose:
• Please note that the collection container must be
sufficiently dimensioned. The end of the drain hose should
not extend into the water.
• Please note that only unpolluted water may be discharged
into the drain.
• The drain must be able to take the respective water
quantity.
• Height differences of up to 10m are permissible.
• Dispose of contaminated water in accordance with the
national regulations.
1. Connect the drain hose (Ø12mm) to the water discharge
connection.
2. Guide the other hose end to a drain or collection container.
• Regularly inspect the drain hose and hose connection for
kinks and dirt. Remove kinks and clean the drain hose,
if required.
TTKwic quick couplings
As standard, the device comes with two integrated TTKwic
quick couplings(7), where condensate discharge hoses of up to
two used dehumidifiers plus condensate pump can be
connected. The entire water discharge is then taking place
centrally via the drain hose of the device.
Note
When using the TTKwic connections of the device,
please make sure that the device is switched on.
If the device is switched off, the accumulated
condensation will not be pumped out and may
overflow.
Should the device – while using the TTKwic
connections – create much less noise during operation
or stop working altogether, set the device to a lower
performance level or switch on TTKwic mode, see
chapter Operation.

10 EN
insulation drying unit Qube+
Positioning the device
When setting up the device, make sure that the warm air
generated by the device is discharged. The room temperature
should not exceed 35°C.
If condenser dryers are operated at temperatures above 35°C
and at high humidity levels permanently, the pressure in the
refrigerant circuit will rise. Consequently the compressor will
permanently run at its limit, which leads to increased wear and
tear.
• If required, ensure that the process air is discharged by
connecting a suitable discharge hose to the process air
discharge connection(18).
• Provide sufficient fresh air supply by ventilating the room
at regular intervals.
• Should the discharge of warm air not be an option, the
device can also be installed outside of the room to be dried
and the hose connection can be established by means of a
PlanoPro door gap nozzle (art.no. 6.100.000.160).
Such an installation may look like this, for example:
The device comes equipped with an overheating protection.
This serves to prevent excessive ambient temperatures.
It protects the materials and devices located in the room.
Start-up
• Use suitable hoses (observe number and diameter) to set
up the drying installation.
• Remove the sealing caps from the connectors to which you
want to connect a hose. If a connector is not needed, the
sealing cap must remain on the connector.
Note
Connectors without a sealing cap or a connected hose
may cause water to escape and thus result in water
damages.
Carefully check the connectors before switching the
device on.
• For drying operations, only use cables and sockets
complying with the regulations. In addition to the 16A
fuse, the socket should also be secured by a 30mA
residual current device (RCD).
Note
We recommend using a suitable mat if the Qube is
placed on sensitive ground.
Inserting the filters
Check whether the filters have been properly inserted into the
device:
• G4 filter sleeve or optional F8 filter sleeve or HEPA filter
with F8 filter sleeve
• demister
• coarse filter (filter mat) with coarse filter fixation
• pump filter
Info
The coarse filter fixation should rest on the coarse filter
to prevent the coarse filter from floating
unintentionally.
Mains connection
• Plug the mains plug into a sufficiently fused socket.
Switching the device on
Press the power button(42) to switch the device on.
The following working stages are available:
• 4 power stages 1-4
• stage 5: boost stage

In accordance with calibration regulations, restoration
companies are so-called "meter users" or "users of
measurement readings", which binds them to observe the
German Weights and Measures Act (MessEG). The MessEG
regulates the recording and transfer of measurement readings
based on which the power consumption costs of the devices
shall be determined.
Info
If a load is connected to the service socket, its energy
consumption will also be measured by the energy
meter.
Connecting the DA4 (external control unit)
The communication port(41) is used for data transfer to the
DA4 control unit. The data may then be forwarded (USB and
modem or USB only).
Additionally, the internal sensor of the DA4 must be connected
via the sensor connection(12).
Emptying the tank
Info
The drain hose must be connected and guided to an
appropriate drain or collection container.
Filling level sensors inside the tank control the automatic
operation of the pump. Once a certain filling level is reached in
the tank, the pump will start to operate automatically:
• The message abpumpen... appears on the LC display.
• The pump drains the accumulated water via the connected
