3.2 Personnel requirements
Only specialist personnel or specifically trained personnel may install and operate the equipment.
The electric connections and the wiring of the device must be executed by a specialist in accordance with all applicable national and
local regulations.
3.3 Personal protective equipment
When working at the system, wear the stipulated personal equipment such as hearing and eye protection, safety boots, helmet,
protective clothing, protective gloves.
See the national regulation of your country for personal protective equipment required.
3.4 Intended use
The device is used in plant systems for stationary heating and cooling circuits. The devices may be used only in systems that are sealed
against corrosion and with the following water types:
• Non-corrosive.
• Chemically non-aggressive.
• Non-toxic.
Minimise the entry of atmospheric oxygen throughout the plant system and into the make-up water.
Note!
Ensure the quality of the make
-up water as specified by national regulations.
–
For example, VDI 2035 or SIA 384-1.
Note!
•
To ensure fault-free operation of the system for the long-term, glycols whose inhibitors prevent corrosion
phenomena must always be used for systems operating with water/glycol mixtures. It must also be ensured that no
foam is formed due to the substances in the water. Otherwise this could endanger the entire function of the vacuum
spray tube degassing as this can lead to sedimentation in the vent pipe and therefore leaks.
•
The specifications of the respective manufacturer are always decisive for the specific properties and mixing ratio of
the water/glycol mixtures.
•
Types of glycol must not be mixed and the concentration is generally to be checked every year (see manufacturer
information).
3.5 Inadmissible operating conditions
The device is not suitable for the following applications:
• Mobile system operation.
• Outdoor operation.
• For use with mineral oils.
• For use with flammable media.
• For use with distilled water.
Note!
It is not permitted to make any modifications to the hydraulic system or the circuitry.

3.6 Residual risks
This device has been manufactured to the current state of the art. However, some residual risk cannot be excluded.
CAUTION
Risk of burns on hot surfaces
Hot surfaces in heating systems can cause burns to the skin.
• Wear protective gloves.
• Please place appropriate warning signs in the vicinity of the device.
CAUTION
Risk of injury due to pressurised liquid
If installation, removal or maintenance work is not carried out correctly, there is a risk of burns and other injuries at the connection
points, if pressurised hot water or hot steam suddenly escapes.
• Ensure proper installation, removal or maintenance work.
• Ensure that the system is de-pressurised before performing installation, removal or maintenance work at the connection points.
WARNING
Risk of injury due to heavy weight
The devices are heavy. Consequently, there is a risk of physical injury and accidents.
• Use suitable lifting equipment for transportation and installation.
CAUTION
Risk of injury upon coming into contact with glycol containing water
Contact with glycol containing water in plant systems for cooling circuits can result in irritation of the skin and eyes.
• Use personal protective equipment (safety clothing, gloves and goggles, for example).

4.4 Function
The device combines the functions make-up and degassing of water for the plant system:
• Gas-rich water is conveyed via the make-up line connection from the plant system to the vacuum spray tube.
• Additional freshwater is conveyed via the make-up line connection from the plant system to the vacuum spray tube.
A freshwater make-up occurs if there is a pressure drop in the plant system.
Sequence of a degassing cycle in the vacuum spray tube
1 Create vacuum in the spray tube 3 Discharge
2 Injection 4 Idling time
The degassing operation uses timer-controlled cycles. A cycle comprises the following phases:
1. Create vacuum in the spray tube.
– The pump starts and conveys water from the vacuum spray tube The pump transports more water from the spray tube than
can be transported via the connection lines of the water make-up. A vacuum is created.
2. Injection
– Opening of the solenoid valves in the make-up lines routes gas-rich water into the spray tube. It is atomised by nozzles in the
spray tube. The atomised water is degassed in the vacuum of the spray tube because of the large surface area resulting from
the atomisation. The degassed water is returned to the plant system via the vacuum pump. The overflow valve means that the
pump is set to a constant working pressure. The working pressure depends on the respective plant system.
3. Discharge
– The pump shuts down. The pressure in the plant system causes more water to be injected into the vacuum spray tube and
degassed. The water level in the vacuum spray tube rises. The gases released in the vacuum spray tube are released into the
ambient atmosphere via the degassing valves.
4. Idling time
– When the gas has been discharged, the device will remain in idle until the next cycle is started. Post-degassing occurs during
the idling time.

Description of the device
Servitec 35-120 with Touch controller — 06.07.2016 - Rev. B English —
15
Degassing programmes
The device controller regulates the degassing process. The controller monitors the operating states and outputs them to the display.
The controller provides 3 different degassing programmes for selection and adjustment:
• Continuous degassing
– For continued degassing over several hours or days in a sequence of degassing cycles without idling periods. This degassing
programme must be selected after commissioning and repairs.
• Interval degassing
– This comprises a limited number of degassing cycles. The system idles between the intervals. This degassing programme must
be selected for continuous operation.
• Make-up degassing
– Is automatically activated for every water make-up during continuous or interval degassing. The sequence corresponds to
continuous degassing. The degassing time is limited by the make-up time.
Make-up variants
There are two make-up variants for the device. These are selected in the controller and set for the device:
• Magcontrol make-up variant.
– For plant systems with diaphragm expansion tanks. The pressure in the plant system is monitored with the aid of the
integrated pressure sensor in the device. If the plant pressure falls below the calculated filling pressure, water make-up is
triggered.
• Levelcontrol make-up variant:
– For plant systems with pressure maintaining stations. The water level in the expansion tank of the pressure maintaining system
is determined with the "LIS" external pressure transducer. If the water level falls in the expansion tank, a signal is triggered at
the device controller to start the water make-up.
