1.1 Description MEIER-BRAKENBERG Top-Climate-System
The MEIER-BRAKENBERG Top-Climate-System is a cooling and humidifying system for agri-
cultural houses and industrial buildings. It is designed for an effective and efficient cooling, hu-
midifying and cleaning of the air inside the house. The working principle is direct evaporative
cooling.
The main components of the system are a high pressure pump unit with an electronic controller
which supplies water with a pressure of 70 bar. The water is distributed in stainless steel pipes
to high pressure fogging nozzles which atomize the water. The extremely small droplets evapo-
rate immediately. The necessary heat energy is extracted from the air –the air cools down. This
cooling effect can reduce the necessary ventilation rate which can save energy. The MEIER-
BRAKENBERG Top-Climate-System is also used to increase the humidity during heating peri-
ods and after the date of entry of young animals.
The electronic controller is responsible for the evaluation of the applied electrical signals from a
climate computer or its own humidity and temperature sensors. The controller switches the
pump and the valves accordingly. In addition, control functions are integrated into the controller
to ensure safe, reliable and long-lasting operation of the system.
NOTE
The system must be monitored regularly despite the built-in control and alarm function - Sever-
al times a day on climatically extreme days.
The Top-Climate-System is intended exclusively for evaporative cooling or air humidification, for
example in stables. Any use beyond this is considered not intended. The manufacturer is not li-
able for any resulting damage. The risk is borne solely by the user. Intended use also includes
observance of all instructions in these assembly instruction and operation manual. Non-
observance of the instructions or improper use will void any warranty claims.
Installation, maintenance and repair work may only be carried out by qualified personnel.

3 Assembly instruction
The Top-Climate-System is generally supplied in components as a modular system. Each sys-
tem is designed to meet the individual requirements of the customer.
Important information!
The system must always be thoroughly flushed before being put into operation. For
this purpose, the ball valves at the ends of the nozzle lines are opened after the as-
sembly of the lines and all lines are thoroughly flushed. The first flushing of the sys-
tem must take place without nozzles. Only after flushing the mounting of the noz-
zles is the last step to complete the system.
3.1 Installation of the pump unit
Place the pump unit on a even, horizontal, clean floor that is easily accessible and adequately
ventilated. Instead of placing the pump unit on the floor, it can alternatively be mounted to a flat
vertical wall using the optional wall mounting kit (Art. 7290). Depending on the wall, suitable
dowels/screws must be used for horizontal mounting of the bracket. The machine feet can be
screwed to the angle plate in prefabricated holes. The pump unit is then suspended from the
holder in a vibration-decoupled manner and fixed with nuts.
Important information!
Check whether a red transport plug still closes the pump housing. If this is the case,
replace it with the supplied oil vent screw. Check the oil level and refill if necessary
(15W-40).
Remove the protective foil from the attached high-pressure hose and connect it to the connect-
ing pipe by means of a cutting ring fitting (remove union nut and cutting ring on one side). Alter-
natively, a PressFix fitting with a suitable connection for the hydraulic hose can be used for the
connection (Art. 7409). If optional modules are used, the hydraulic hose is connected to the re-
spective module (see chapter 3.3 “Installation of additional modules”).
The pump unit is designed for connection to a MEIER-BRAKENBERG Touch Controller. With-
out the MEIER-BRAKENBERG Touch Controller no correct function of the system can be guar-
anteed. The pump unit must not be connected to the power supply until “First start-up” (chapter
4.1)!
(Art. 7290)

Seite 17
3.2 Installation of the filter unit
Selection of the filter unit:
If a pump unit is connected directly, a filter unit with integrated main valve is required (the valve
plug is connected to the Touch Controller). A 1/2"-valve is sufficient for up to 25 l/min, a 3/4"-
valve is required for more than 25 l/min. A pressure gauge is installed behind the valve. While
the pump is running, it must be ensured under all operating conditions that the pressure at this
pressure gauge (inlet pressure of the pump) is 1...4 bar. Filter units with bypass can be used for
the dosing of additives, in which any 3/4" dosing units can be installed. Usually filter units with 4
filters are used, only with very good water quality on site, filter units with only 2 filters can be
used. The smallest required filtration degree is 1 micron.
Mount the prefabricated filter battery horizontally on a wall or bracket near the pump unit.
Be sure to observe the installation direction! Filter sizes are pressed into the filter inserts
(25 micron, 10 micron, 5 micron, 1 micron). The water must flow through the filter battery in this
direction. This ensures optimum filtration of the supply water and a long service life of the filter
cartridges.
The supply line is connected to the input of the filter unit (3/4" IT). The supply line should at
least correspond to the diameter of the pump suction connection, preferably larger, and should
be as free as possible of resistances and throttling points. There is a hose connector at the out-
let of the filter unit. Here the 3/4" hose of the pump unit (or a hose to a tank) is connected. The
hose must be laid in such a way that it is not bent too much and does not rub. The valve con-
nector cable is connected to the Touch Controller according to the “Anschlusspläne/Wiring
plans” (chapter 7). After the connection, the manual shut-off valve can be opened and the filters
can be put under water. Before switching on the system, the filters need to be vented: Open the
breather valves on the filter head until only water emerges.
When later replacing used filter cartridges, make sure that the O-ring is cleaned and lightly
greased (e.g. with Vaseline).
Important information!
Make sure that the order of the filter cartridges is correct.
Check the condition of the filter cartridges regularly. If they are very dirty, replace
them. Regular replacement (e.g. once a year) is recommended. Dirty filters can
lead to an insufficient inlet pressure below 1 bar.
When using a chem. filter cartridge (5 micron chem.), it must be replaced regularly
(twice a year or after 150 m³ flow).
(Example: Art. 7126-V1-B)

Seite 18
3.3 Installation of additional modules
Important information!
The hoses must be installed in such a way that they cannot rub against other com-
ponents/sharp edges. The hoses must not be bent too much. Non-observance will
reduce the lifetime of the hose.
The pressure relief module for connection to the connection
pipe (Art. 7113 - STANDARD) is mounted between the hydrau-
lic hose of the pump unit and the connection pipe. For the con-
nections of the T-piece, the information in chapter 3.5.2 “Cutting
ring fittings”must be observed. The mounting position of the
valve should be with the solenoid upwards. The hose at the
connector should be led into the drain. The cable of the valve
connector is connected to the Touch Controller according to the
specifications in the chapter 7 “Anschlusspläne/Wiring plans”.
The additional module 2-house without pressure relief
(Art. 7114) is mounted near the pump unit on a wall or alterna-
tively in the pump unit on the rear wall of the angle plate. The
mounting position of the valves should be with the solenoids
pointing upwards. The connector between the valves is con-
nected to the hydraulic hose of the pump unit. The two hydraulic
hoses behind the valves are connected to the connecting pipes
to the two compartments. The cable of the double valve con-
nector is connected to the Touch Controller according to the
specifications in the chapter 7 “Anschlusspläne/Wiring plans”
(version LC-2 or LCS-2 required!).
The additional module 2-house with pressure relief (Art. 7115)
is mounted near the pump unit on a wall or alternatively in the
pump unit on the rear wall of the angle plate. The mounting po-
sition of the valve block should be with the solenoids pointing
upwards. The right connection (P) is connected to the hydraulic
hose of the pump unit. The hose at the nozzle (R) is led into the
drain. The two hydraulic hoses behind the valve block (A1 and
A2) are connected to the connecting pipes to the two compart-
ments. The cables of the double valve connectors are connect-
ed to the Touch Controller according to the specifications in the
chapter 7 “Anschlusspläne/Wiring plans” (version LC-2 or
LCS-2 required!). The two valves at the inlet of the valve block
control the two outputs. The two valves at the block outlet each
serve as pressure relief.
NOTE
All protective conductors of the modules must be connected to the protective conductor ter-
minal in the touch controller. The multicore cables must be connected according to the wire
colors in the chapter 7 “Anschlusspläne/Wiring plans”. For the double valve connectors of the
2-house modules, the position of the respective connectors must be taken into account
(compare the function of the valves in the wiring plans).

3.4 Installation MEIER-BRAKENBERG Touch Controller
Important information!
The MEIER-BRAKENBERG Touch Controller is essential for controlling the Top-
Climate-System. The manufacturer accepts no liability for the installation of a sys-
tem without the Touch Controller.
The MEIER-BRAKENBERG Touch Controller should be installed in a dry, clean and easily ac-
cessible location near the pump unit. For mounting, the cover must be opened and the housing
is fastened with suitable screws through the holes intended for fixation.
DANGER
Warning of electrical hazard!
Touching live parts or parts that have become live due faults, poses a direct risk of death. Dam-
age to the insulation or individual parts can be fatal hazard.
Only electrical specialists are allowed to work on the system’s electrical equipment.
When working in the electrical equipment always shut off the power and verify safe isolation.
Observe the regulations of VDE (Verband der Elektrotechnik Elektronik Informationstechnik
e.V.) or IEC (International Electronical Commission) and the national accident prevention
regulations for electrical systems and equipment.
The MEIER-BRAKENBERG Touch Controller has a wide voltage input (85-264 V, 50/60 Hz).
The voltage supply is usually made via a multi-core connection cable of the pump unit and must
usually be 220-240 V to supply the valves. Other cables (e.g. from additional modules, pressure
switches, climate computers, etc.) are also inserted into the Touch Controller. Depending on the
pump unit and the additional modules, the appropriate Touch Controller must be selected (for
pump units with frequency inverter, the "LCM vario" version is required).
NOTE
Suitable cable glands must be used to ensure good sealing and strain relief of the cables.
The cables are connected according to the wiring
plans (see chapter 7 "Anschlusspläne/Wiring
plans").
The multi-core cables of the pump unit are labelled
with numbers. In the circuit diagrams, the number-
ing is marked as shown in the adjacent detail. Col-
oured cables are marked accordingly (abbrevia-
tions according to IEC 60757). GNYE
(green/yellow) identifies the protective conductor.
The protective conductors of all components must
be connected to each other!
Important information!
Make sure that the mainboard and the IO-Card are not confused when connecting
the cables. Mainboard and IO-Card are marked in the circuit diagrams. Attention:
Sometimes there is the same name of the terminals on both boards.

3.4.1. Connection of external climate computers and sensors
The correct pin assignment for external climate computers and sensors can be found in the wir-
ing plans (see chapter 7 “Anschlusspläne/Wiring plans”).
CAUTION
To avoid malfunctions, lay all cables in the controller close to the base plate.
Never connect or disconnect components when the controller is switched on.
External climate computer
The potential-free switching contact of an external climate computer is connected to the pre-
scribed input terminals of the controllers (e.g. DI1 and 24V for MBWEICH3; see chapter 7 "Wir-
ing diagrams/Wiring plans"). These cables must be laid separately and should be shielded. Only
potential-free cables are allowed for connection. If the potential-free contact is closed (24V are
applied to the input), the system cools/humidifies.
Sensors
Sensors are also connected to the input terminals. These cables must also be installed sepa-
rately. The cables must have a low resistance (1.5 mm²).
3.4.2. CAN connection
In the LCM vario version (Art. 7745), the controller can be connected to extension boxes
(Art. 7750) if required. Eight additional outputs are available for each box. The connection is
