2.1. Installation Documentation
2.2. Legal Installation Regulations
Please, ensure disposal of the device complies with the current building regulations and lawful accident prevention rules in your country (get more information with the relevant professional associations).
2.3. Legal Installation Authorization
Please,ensure strict compliance with the legal local requirements for installation of ventilation and electrical systems in your country. Check your legal permission for installation.
The ventilation system with heat recovery is a ‘SELV’-equipment (Safe Extra Low Voltage) which operates only by DC power of 7-15V, however, the Twist Control is connected to 230V AC according to legal installation authorization required in Germany.
2.4. Installation in Rooms with Open Fireplaces
In case of use of RV 30 equipment produced by Ventoxx Company in rooms with open fireplaces or stoves, it is necessary to ensure installation complies with the applicable rules and standards in respective country. Apart from fireplaces with balanced flue air supply air may be needed for operation of all other operating units with an open flame. When stoves or other built-in components and Ventoxx devices of RV product line are used at the same time, a prior consult from a competent regional chimneysweep is essential because of the risk of serious personal injury andproperty damage. There is suffocation
threat!

2.5. Installation Instructions for ventilation units Ventoxx RV 30,Ventoxx RV 30s, Ventoxx RV 25
2.5.1. Tools Needed for Installation
For Installation you will need the following listed tools and protective equipment. Tools:
Level Utility knife Core drilling unit with 235 -240 mm drill bits for retrofitting Phase tester (electrical fitting) Screwdriver cross medium size (cover installation) Wrench Size 10 (mounting outer cover) Wire stripper (for cable mounting) Spatula (inserting the control installation box) Hammer and chisel or drill with drilling crown (inserting the receiving box)
Please, use the following protective equipment for installation:
Wear work gloves Wear protective goggles Use hearing protection Wear head protection Wear safety shoes
2.5.2. Additional Accessories Needed for Installation
The following additional accessories are required for installation, which are not included in the package:
PU installation foam (please, follow the current safety regulations of your country for
using PU installation foam)
Mounting plaster Various cables(see section 2.5.8 Cabling on page 12 for details)
10
2.5.4. Allocation of the Fan
Ventoxx RV units work on a pendulum fan principle. In “Ventilation with Heat Recovery” operation mode two units always work together(one as an air supply and the other as an air outlet). The running direction will change every 68 seconds. Therefore, the factory sets Ventoxx RV units working in opposite direction in one delivery. For this purpose the units are marked with blue and red circles on the fan.
When installing the fans please note that the associated fans always have different colour markers (blue and red).
2.5.5. Installation in a New Building – Creating an Installation Opening
When constructing new buildings, we recommend providing the necessary openings in the shell of the house. By making openings, e.g., in the brickwork, with the dimensions 232 mm x 232 mm, a subsequent core drilling can be avoided.
Depending on the company and tool inventory, core drilling can be more economical, particularly in Germany.
11
2.5.6. Installation in an Old Building–Creating an Installation Opening
To minimize additional filthy and unnecessary work during installation, we recommend core drilling to create an opening for Ventoxx RV unit. It will also make the further steps easier. Ensure the drill bit can provide an opening of 230-240 mm. The opening should also have a slight slope to the outside (2 degrees).
When drilling a wall opening, make sure:
That no people can be injured and/or object can be damaged by the fall out of wall
fractions;
No wires or pipes are available in the drilled wall; That the hole does not influence the bearing capacity of the wall; That creation of an opening has no effect on the physics of the building, e.g.,
penetration of vapour control or rain protection path;
That all necessary protective equipment is applied.
12
2.5.7. Preparing for Installation
The following steps should be taken before the professional installation:
Unpack the unit. Check the completeness of the contents. Your delivery has the following
components:
1 x Ventilator with Heat Exchanger Installation Unit1 x Piping Segment Consisting of 3 Elements Assembled2 x Round-head Screws with Square Neck2 x Screw Nuts1 x Inner Cover1 x Outer Cover1 x Sealing Ring (Self-Adhesive )
Remove the installation unit (ventilator with heat exchanger) from the piping and
secure it against damage such as knocks or contamination.
The heat exchanger is made of ceramics and can be easily damaged by knocks or falling!
2.5.8. Cabling
Cable Connecting
To connect the control in the provided location, the room must have 230 V cabling. In the new building, in particular, at least one empty wiring conduit leading to the place of future control is recommended to be provided before plastering.
Please, note that this service can only be provided by an authorized supplier representative (e.g., electrician) in Germany.
Cabling Ventoxx RV ventilation units
Low-voltage cables must lead from the control to the relevant associated fans. For this a wiring with a cable cross-section 3 x 0.75mm² is sufficient. As a power feed cable (connection between electrical power network and transformer) a wiring with a cable cross-section not less than 3 x 1.5mm² is sufficient. Please, note that there should be enough overhang at both ends to connect the control and the fan. An overhang of 40 cm should be provided.
In an old building, laying low voltage cabling in corners and under wallpaper is recommended to ensure minimum intervention to the existing inventory.
13
2.5.9. Fitting of the Telescopic Pipe: Steps 1–5
When assembling and installing the telescopic pipe, deformations must be avoided! The form of the ventilator with heat exchanger installation unit is accurately adapted to the pipe!
It is necessary to leave the space between the wall and the pipe. The inner-side vapour barrier must be connected to the unit, if available. The same applies to an external rain protection path, if available. There is a threat of penetration of condensate due to an improperly attached vapour barrier or penetration of driving rain by improperly connected rain protection path!
The standard telescopic pipe can be built into the wall of maximum thickness of 310 mm. If your building hasthicker walls, you need additional pipe elements for piping system (please, specify the wall thickness when ordering, the required additional elements are included in a separate packaging).
Step 1
Accurately measure the total outer wall thickness (including plaster layer). Add extra 10 mm.
Step 2
The piping is pre-assembled. You can supplement the piping inside, as appropriate, by the necessary elements to the pipe length determined in Step 1:
Inner Outer

2.5.10. Installing the Piping into the Wall: Steps 6–10
During installation of the piping system into the wall, note the following things:
The pipe must be pre-assembled as described in2.5.9, completely and tightly The ventilator with heat exchanger installation unit is not used in the piping The opening in the wall is free of dust and debris
Step 6
Slide the pre-assembled pipe into the opening. There should a little slope of the piping to the outside (about 2%) to ensure the further condensation drainage.
Observe the mounting direction. The screws must face the front side. .
Ensure the placement of the outside carriage bolts (fastening the outer cover) is
horizontal. Vertical and horizontal mounting of the outer cover is dependent
thereon.
.

Step 7
Turn the pipe into the correct position. Fix the pipe so that the sealing ring on the pipe top comes to rest. Insert the enclosed wedges to secure the position of the tube. Wedge the pipe on four sides.
Step 8
Check there is sufficient slope of piping to the outside (about 2%), and the position of the screws on the front side is horizontal.
Step 9
Wear work gloves and protective goggles to protect your eyes from contamination and damage with PU mounting foam! Please follow safety instructions for installing the product you are using.
Seal the pipe with PU mounting foam. It is necessary to leave the space between the wall and the pipe to ensure a stable position of the piping.
Please keep in mind connecting a vapour barrier and rain protection path to avoid structural damage!
Further installation steps may be takenonly after hardening of PU-foam. Please follow the manufacturer’s instructions for hardening time for polyurethane foam.
17
Step 10
Insert the unit control connection cable into the pipe. The cabling between the control and theunitis provided. The actual connection of the control is described hereinafter (see how to do this in chapter 3 of these instructions).
2.5.11. Installation of the Outer Cover: Steps 11–13
When installing the cover, please, ensure there is sufficient stability of your footprint. Secure yourself against falling hazard. If necessary, please, check the current statutory safety regulations.
Step 11
Attach the mounting panel of the outer cover to the outer wall using the screws and nuts supplied.
Due to the outer wall flatness tolerances, installation of the outer cover can be difficult. Therefore, we recommend the mounting screws not to be over tightened.
Step 12
Insert the outer cover to the mounting panel.
18
Step 13
UV-resistant silicone can be used to close the top and side gaps between the outer cover and the wall.
Please note: silicone joints are maintenance joints.
After installation of the pipe and the outer cover, the ventilation system RV 30should be installed as follows:
After installation of the pipe and the additional compensation box, as well as the attachment of the outer cover on the compensation box, the ventilation system RV 30s should be installed as follows:
After installation of the pipe and the additional air duct on the piping, as well as the attachment of the ventilation grille to the air duct, the ventilation system RV 25 should be installed as follows:
the ventilation grille sits in the window reveal, the ventilation duct sits hidden in the facade insulation.
19
2.5.12. Installation of the Ventilator with Heat Exchanger Unit: Steps 14 and 15
Step 14
Insert the ventilator with heat exchanger installation unit into the pipe. (The fan should point in the direction of the interior). The unit is set horizontally and then pushed with light pressure into the pipe.
For the drainage of the possibly accumulating condensation water in the heat exchanger, the ventilator with heat exchanger installation unit must be pushed to the end of the telescopic pipe. Thus the noise in the living room caused by the unit will be reduced, too.
Be careful when inserting the ventilator with heat exchanger installation unit to avoid
pressure on the fan! Only the edges of the installation unit (foam) can be pressed.
Step 15
Connect the connection cable to the fan according to the connection scheme (see chapter 3.2. of these instructions).
20
2.5.13. Installation of the Inner Cover: Step 16
Step 16
Insert the inner cover. Turn the inner cover clockwise to close. To open, turn it anti-clockwise.
Close the inner cover when Ventoxx ventilation unit is off (for example, in strong winds, to avoid noise and drafts).
3. Connecting Twist Control
3.1. General Information
3.1.1. Intended Use
Ventoxx Twist Control is used to operate Ventoxx RV ventilation units. When installed and used as intended, connection and operation of the controller constitutes no danger to people or property.
If the controller is used for other purposes than stated herein, there can be threats of injury or damage. The manufacturer or supplier is not liable for any damages arising from improper use. The risk is borne by the user only.
3.1.2. Safety Instructions
Risk of injury!Improper installation and connection to the power supply system can cause personal injury or property damage. Please, carefully follow all the relevant regulations for connection of electrical equipment and accident prevention applicable in your country.
Connection of control and/or fan to 230V voltage leads to certain damage and loss of equipment. There is a risk of serious personal injury due to electrocution!
3.1.3. Scope of Delivery
The necessary control for the operation of the device is not normally included in the standard packaging of Ventoxx ventilation unit but is delivered separately packed.
21
3.2. Connection and Installation of the Control
3.2.1. Red Fan-Blue Fan
The centre of the front of each our reversible fans is marked with a blue or red circle. As our system works in pendulum fan method, ensure that each system has the same number of blue and red fans.
Please also note this when connecting the units.
1) Control: Input Voltage 12V DC
2) Front Panel
3) Transformer (for connection of up to 4 units)
4) Flush-Mounted Box
22
When a system has two fans of the same colour marking installed, they operate in the same direction and not as a pendulum version. Accordingly, there can be no heat recovery.
3.2.2. Connection Scheme
Since Ventoxx ventilation units and Ventoxx Twist Control will be built-in, you should ask the representatives of the manufacturer or a specialist for an advice about the choice of installation locations.
When choosing the installation location for the control, it should be noted that certain operating modes of the ventilation units provide the supply of fresh air of the outside temperature. In case of work in lower temperatures for long hours (for example, in winter) this can lead to negative results.
Any number of ventilation units can be connected to the Ventoxx Twist Control. However, please, make sure that sufficient power is fed into the power grid. The power and control unit are installed in the fans themselves. The control gives the fan only the command for controlling the operation modes.
Note that Twist Control and RV
ventilation units are never supplied
with 230V AC; only low-voltage current may be applied. 230V electricity will destroy the device and lead to a significant risk of injury due to electrocution.
This standard connection scheme shows the optimal choice for the installation location. The power supply can be placed at any point of the electricity circuit.
3.3.5.1. Operation Mode “Ventilation with Heat Recovery”
When turning the knob of the control clockwise, only one green LED lit up shows the first speed, if two diodes are on – it is the second speed, etc. In this mode the ventilation system most efficiently saves the heat from the consumed air in the heat storage and enriches the incoming fresh outside air with this heat.
When the device is reversing, it is indicated by the blinking of the blue LED. The ventilation unites reversing every 68 seconds. This visual illumination only means that the fans have changed the direction of rotation (the function appears only when the illumination is activated).
The best results are achieved when the unit is steadily running on low levels 1-2. In addition to high heat gain, the noise level is the lowest!
3.3.5.2. Operation Mode “Ventilation at the Selected Speed”
By pressing the rotary knob when " Ventilation with Heat Recovery " operation mode is activated, the blue LED lights are on and the ventilation units start working in "Ventilation" operation mode which means that the reversing is switched off and cold air of an outside temperature flows into the rooms.
By pressing the knob again, the blueLED begins to flash, which means that the ventilation units work in the "Ventilation" operating mode but have changed the direction of air flow, for example, when in room 1 the ventilation unit has been working to supply air and in room 2 – to let exhaust air out, therefore, air will be removed from room 1 and let inside in room 2.
To switch off the "Ventilation" operation mode, you have to use the control knob only one step to any other speed. To start the "Ventilation" operation modeat different speed, you have to select the required speed and then press the knob.
This working mode has no automatic shutdown and is only switched off when turning the knob.
3.3.5.3. Operation Mode “High-PerformanceVentilation”
To start this operation mode you have to switch off the ventilation units by turning the knob of the control anti­clockwise until a red LED lights up. Now please press the knob until the blue LED lightsup. The ventilation units are now working in the "High-PerformanceVentilation" operation mode.Press the knob againto switch tothe other direction. Here the blue LED begins to flash like in the “Ventilation at the Selected Speed” operation mode.
After about 10 minutes this modewill automatically switchoff and the system will continue operating as ventilation with heat recovery. By pressing the knob you return to the "Ventilation with Heat Recovery" mode.
3.3.5.4. Operation Mode “Power Off”
To turn off the device turn the knob of the control anti­clockwise until the red LED light up.

4. Maintenance and Repairs
Before you start any kind of maintenance, switch Ventoxx RV units off and disconnect them from the power supply. The ceramic heat exchanger is fragile, do handle it carefully and do not let it fall.
4.1. Maintenance of the Unit
4.1.1. Filter
The filter is suitable for long-term use. Cleaning is carried out under running water. If damaged, the filter must be replaced.
Filter requires changing or cleaning every three months. A flashing red LED on the control indicates that.
4.1.2. Fan
The condition of the fan should be checked annually. Even if the filter is cleaned regularly, a small amount of dust can stick to the fan. This may lead to lower efficiency. The fan can be cleaned with airflow or with a soft sponge or brush.
4.1.3. Heat Exchanger
We recommend annual check of heat exchange unit. If there is contamination of the heat exchanger, proceed as follows:
Turn the power off Remove the inner cover and the filter Disconnect the electrical terminal Get the ventilator unit removed from the piping Carefully remove the fan from the ventilator unit Now the heat exchanger can be cleaned with a vacuum cleaner or a damp cloth.
We recommend you to avoid cleaning the unit in the dishwasher not to damage the insulation!
4.1.4. Control
The control itself does not require any special cleaning. Should there be any cleaning of Ventoxx RV unit or its filter change, yet the fans must be turned off via the control (see operating modes).
Problem
Possible Solution: Please, check…
Low airflow
You notice that airflow is too low
the fan speed set, and, if necessary, set a higher fan
speed (see 3.3.5.2)
the inner cover panel - it must be open; if it is not, open it the dust filter: check it for dirt and clean if necessary (see
4.1.1)
the heat accumulator: it could also be contaminated. If
this is the case, please clean it (see 4.1.3)
Cold airflow
You felt that air flow is too cold
whether the ventilation units are connected in
accordance with the installation instructions. A red and a blue fan are always working as a pendulum unit (see
2.5.4)
if the device is working in the "High-Performance
Ventilation", and, therefore, there is no heat recovery. Please, adjust to “Ventilation with Heat Recovery" operation mode (see 3.3.5.1)
Strange noise My fan is making strange
sounds ...?
if the ventilator with heat exchanger installation unit is
installed according to the instructions? Perhaps, it is mounted into the pipe too close to the inner wall of the house. Then it should be pushed further into the pipe. Please, install the unit according to the instructions (see
2.5.12)
if the fan is dirty or an alien object is in the fan? – Please,
clean it and remove any alien objects (see 4.1.2)
the set fan speed; perhaps, it is too high. Reduce the fan
speed (see 3.3.5.2)
Stoppage of the Fans: My fan stopped working…?
if the fan has been connected properly? if there is a power supply to the fan? if the control has been connected properly? If the control has been connected according to the
instructions?
If your answer to all the above mentioned questions is "yes", there may be a defective control or a defective fan. In this case, please, contact one of our dealers.
