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:
•Outdoor operation.
•For the use with mineral oils.
•For the use with flammable media.
•For the use with distilled water.
Note!
It is not permitted to make any modifications to the hydraulic system or the circuitry.

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.
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).
CAUTION
Risk of injury due to heavy device weight
The device weight may cause physical injury or accidents.
•If necessary, work with a second person during assembly or disassembly.
ATTENTION
Device damage during transport
Improper transporting procedures can cause damage to the connections for degassing and makeup lines.
•Use suitable covers to protect the connections against damage.
•Only transport the device in an upright position.
ATTENTION
Property damage during transport
Improper transporting procedures may cause damage.
•Fasten the device with suitable transport securing means such as straps.

Description of the device
4.1
Description
The device is a degassing and make-up station. Its main areas of application are heating and cooling circuits and systems in which
interruptions of operations due to dissolved or free gases. The device works only with a vacuum pump designed for this purpose. This
design enables a compact footprint for small and mid-sized systems.
The device provides the following safety features:
•No direct intake of air thanks to a regulation of the pressure maintenance with automatic make-up.
•No circulation issues caused by free bubbles in the circuit water.
•Reduced corrosion damage due to oxygen removal from fill and make-up water.

Function
The device degasses the water from the facility system and the fresh water from the make-up line. It removes up to 90 percent of the
dissolved gases from the water. The degassing operation uses timer-controlled cycles.
A cycle comprises the following phases:
1. Vacuum is drawn
– The "PU“ pump draws a vacuum. The inlet to the "DC" pump remains closed.
2. Atomisation
– The inlet to the "PU" vacuum pump is opened. Depending on the actual demand, a partial flow of the gas-rich system water of
the facility system or the fresh make-up water are introduced through the "DC" or "WC" lines of the device. The water is then
finely atomised in the vacuum pump. The large surface of the atomised water and the large gas saturation headway to the
vacuum result in a degassing of the water. The degassed water is returned to the system via the vacuum pump.
3. Discharge
– The "PU" vacuum pump shuts off. The system continues to atomise and degas water. The water level in the vacuum pump rises.
The gases separated from the water are discharged into the ambient atmosphere via the "DV" degassing valve.
4. Idling time
– When the gas has been discharged, the device will remain in idle until the next cycle is started.
