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

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.

Operational Guidelines- Z-WRG RONDO Plus
Caution
Do not remove the cover of the electrical part yourself in order to avoid a the risk of an electric shock. There
are no parts behind the cover of the electrical part and the base plate that need to be maintained by the
customer. Please let expert staff carry out electrical interventions.
The housing towards the room side respectively the room- sided cover is easiest to clean with a humid cloth.
In order to avoid damages of the surface only use water and a little detergent. Always make sure that no
water can ingress.
Cleaning and Care
With the purchase of the Z- WRG RONDO Plus you decided to buy a particularly high- quality product that is
designedfor permanent operation. In case you have to make use of the warranty service,
bought the device from.
Previously read the operating guidelines carefully. That way you can exclude that the mistake did not arise
please contact the firm you from incorrect setting or handling.
General Operating Instructions / Warranty
All Ventomaxx products are subject to the implied warranty of two years. It contains material and production
defects. The warranty starts with the date on which the product was purchased respectively installed. You
have to submit the evidence for the purchase or the installation. For this we ask you for a voucher a receipt
where the dates can be found in. Ventomaxx reserves the right to reject the warranty if the evidence for the
purchase and/or installation is not provided.
In case of a justified defect covered by the warranty, that is due to a material defect or faulty production,
Ventomaxx will either repair the product or replace defective components respectively the whole product.
The warranty is excluded for the following cases if:
- the assembly and operating guidelines have been ignored
- the assembly/ installation was carried out wrong
- the device was improper handled/ willfully or deliberately damaged or destroyed
- intervention(s) on the device were not carried out by expert staff
- components are affected that are exposed to normal, foreseeable stress
- No original spare parts are used
In order to guarantee a consistent quality of fresh air, please check the condition of the filter and the
components that conduct air flow regularly. Please exchange the filter at least once a year.
Filter Exchange
All WRG RONDO Plus devices are frost- resistant up to -20°C because of the cyclic air intake and exhaust. In
contrast to conventional cross- flow or counterflow heat exchangers that have to start with defrosting
operations already at 0°C, Z WRG RONDO Plus devices always ensure a maximal heat recovery efficiency in the
program mode “ Permanent Operation“.
„Winter Operation Mode“ / Increased Frost Protection
During “winter operation mode” with high moisture and/or low temperatures outside the system carrier unit
can be turned around by 180° in order to make the ventilator show to the room side. Of course, this position
can be kept in summer, but the advantage of the “standard summer operation constitutes in a lower noise
level. Thus it is up to the user to run the device in “winter operation” or “summer operation”.

During the filter exchange the system carrier unit should be removed and
inspected for soiling. It is recommended to clean the heat exchanger from
time to time with running water or to put it into the dishwasher
1
Only a clean ventilation device is able
to guarantee a hygienic fresh air
supply. Because the operating
environment and the device runtimes
can differ occasionally, we recommend
inspecting the filter and the system
carrier unit for proper condition once
more than described in the following
during the first months of operation. If
necessary the ceramic heat exchanger
can be cleaned in the dishwasher.
Filters are hygiene products and need
to be changed if their soiled or dirty. In
order to admonish you to exchange
the filter, your Z-WRG RONDO Plus
device is equipped with a filter
exchange display (s. p. 14).
On the ventilation device there are no
maintenance works to do.
The filter exchange is carried out as
follows:
a) remove the front cover of the
device; for this press the unlocking in
the middle and unhook the cover via
light upward movement (fig. 1).
b) the filter frame is held by two snaps
in the housing of the device ; by
pressing the straps it is possible to
remove the filter frame without
needing a tool (fig. 2).
c) Insert the new filter in reverse order
into the housing; hang in the front
cover again and make it snap in using
soft pressure.
Please keep in mind that depending of
the place of the ventilation device it
might be necessary to exchange the
filter every 6 to 8 months. An
inspection of the filter on dirt or soil
thus should be carried out regularly.
Independent from the degree of dirt
the filters need to be exchanged for
hygienic reasons at least once a year.
