Caution!
Save Device From Moisture and Wetness!
Always Remove the Electronic Connection Before You Open the Device!
All persons that are involved in the assembly, installation and maintenance of the device have to be qualified
appropriately. Observe these operating guidelines and the general approval from the construction supervision
strictly! Missing documents will be sent to you quickly after a request.
The ventilation device is operated with low voltage. The control unit is connected right to the grid. The control
of the device must only be connected to the planned electrical voltage and frequency that fits the description
on the nameplate of the device exactly.
The cables entry/entries of the UP Control must not be loaded on tension! Towards the device
there has to be enough cable length. Otherwise the cable can be damaged which can lead to a
fatal electric shock.
For cleaning and revision the device has to be turned off and all operations with it have to be stopped.
Bigger dirt in as well as on the device must only be cleared up by a specialist. The electric circuit has
to be interrupted on all poles.
The cleaning of the room sided cover must only be carried out with a wet cloth. The ingress of water or other
liquids into the device must be avoided. If this happens however, immediately disconnect the power from the
grid by pulling the power plug or switching off the fuse of the device. Don´t reactivate the device and ensure
that no unauthorized activation can happen.
First approve that the packaging and the single accessories are in a perfect condition. Especially have a close
look on the external power cable and the power cable towards the ventilation unit. They also have to be in a
perfect condition. There must not be any kinks or damages.

Z-WRG RONDO Plus room ventilation devices are easy to install in all common wall structures and end almost
flush on the inside as well as on the outside due to a correct assembly and installation.
It is a modularized system in order to enable the preparation already in the shell construction phase.
The Z- WRG System is funded on a central control of the ventilation devices. The central control unit is
connected to the grid (alternating current/AC) with 85-260V, 50-60Hz. The ventilation units are connected to the
central control unit via star shaped bell wires. The distance between the central control unit and the farthest
ventilation unit should not exceed 50 meters.
Please note:
The integration of the ventilation device into the wall requires openings in the outside wall that have to be built
during the construction. The required opening has to fulfill the requirements of the upcoming figure. It has to be
200mm high and 190mm wide. This assembly and installation instruction shows the integration of a ventilation
device in a monolith composition of the outside wall. Please check which kind of composition the relevant wall
has. Besides, only use the clamping elements that the producer dictates.
Depending on the attributes of the wall different prescription or rules have to be observed. (e.g. for a façade that
contains rockwood, etc.). Thus the installation has to be carried out by a specialized firm. If you are not sure,
which craft can be considered for the assembly or which tools or auxiliary means are necessary for a
professional installation, please contact Ventomaxx! Always consider the notes of the device manufacturer/
machine supplier while using them. Do not forget to wear the recommended protective clothing and equipment
(e.g. a mask, eye guards, gloves, etc.)
Consider with the selection of the installation place:
Supply lines must not take course on/behind the borehole locations;
Multishell strucutres: Always consider that the damaged vapour barrier is tightly sealed after the prescriptions of
the manufacturer.
Weathering stressed areas: on the outside of the ventilation unit a weather protection has to be installed (Also
consider the Notes to the corresponding installation types).
The ventilation device has to be positioned on the inside in a way that a revision of the device is possible at any
time. The air outlet must remain free in an area of ca. 25- 30cm. It must not be blocked or impeded by furniture,
etc..
General Prerequisites
Assembly / Installation Instruction
If the device does not operate correctly please consult an authorized specialist.
Besides the exchange of the filter or the cleaning of the device no further maintenance operations are
necessary. Always disconnect the power from the grid or switch off the fuse of the device.
Z- WRG RONDO Plus is constructed for the ventilation of dry interior rooms. The air outflow must not be covered by
any kind of object. A warranty for other usage cannot by guaranteed. In order to avoid damages by moisture
or health damages, always be aware of appropriate room ventilation. Depending on the usage of the room it
might be necessary to support the ventilation effect with additional window openings (e.g. brief and intensive
airing out for five to ten minutes) or the installation of an alliance of several Z-WRG Plus devices.
For the correct operation of the decentralized room ventilation system WRG Plus it is a prerequisite that the
combustion air lines have a closure capability.

Ventilation devices of the Z- WRG
Plus series are operated via a
central control unit. The necessary
12 V low potential voltage is also
provided this way.
For the electrical power supply
of the central control unit a 230 V
electrical connection is necessary,
fused with 6 A.
The single ventilation units are
connected with the central control
unit via star- shaped low voltage
lines 2x2x0.6. The length of the
longest line should not exceed
50 meters.
