4. Installation
4.1 Transport and storage
• Handle with care, do not throw!
• Dry and cool storage place.
4.2 Unpacking
• Observe when unpacking:
– No humidity should get into gas-leading parts!
– No foreign matter should get into gas-leading parts!
• Mount as soon as possible after unpacking.
4.3 Mounting
Requirements for mounting
• Installations at the pressure side from the containers resp. the
evaporator are present and checked for tightness
• Piping has been rinsed with nitrogen
– no more soiling present
• In case of design without liquid gas trap and for mounting to
header lines: Filter and liquid gas trap resp. pressure reducing
valve has been installed directly before the vacuum regulator
• Directly before the vacuum regulator the highest temperature
in the course of the pressure gas lines is present.
– If necessary, wrap a heater band around the pressure line
connection of the vacuum regulator.
5. Commissioning
5.1 Preparations for commissioning
5.1.1 Vacuum connections
• At the vacuum regulator, connect the vacuum line and connect
it to the dosing regulators.
• Connect the overpressure line to the overpressure connection.
• Connect the vacuum line to the injector.
5.1.2 Pressure line connection
• Slightly apply grease to the gasket, if necessary
• Connect the pressure line to the pressure line connection
5.1.3 Electrical connections
Connecting the liquid trap (option)
• Connect mains cable of the liquid trap with the mains
Connecting the contact manometer (option)
• Connect two cables with an external evaluation device
Warning
Ensure that all container valves are closed before
mounting.
Only use the intended line types!
Caution
In case of design without mounting plate:
The device will only be carried by the connection with
the pressure line.
Ensure that all piping is free of distortion.
Do not mount the device in a distorted manner.
Warning
Before connecting, ensure that the valves of all gas
containers are closed.
Only use the intended line types!
Caution
Only tighten the union nuts of the vacuum
connections by hand. Do not use any tools!
Danger of damages!
Maximum length of the vacuum line, see chapter
2.7 Recommended diameter
Warning
Lead the overpressure line downwards, as chlorine is
heavier than air.
Connect the overpressure line to a suitable
adsorption device. If using a gas warning device:
Mount the sensor in a distance of about 10 cm from
the outlet hole of the adsorption device.
The overpressure line must end in the room, never
lead to the open air!
Note
Ensure that the pressure lines are as short as
possible.
Caution
Before connecting the mains cable:
Check if the mains voltage indicated on the type
plate corresponds to the local mains voltage. Wrong
voltage can lead to damages of the product!
To ensure electromagnetic compatibility (EMC):
Signal lines must be shielded. The shield must be
connected to PE or ground on the side of the
counterpart, par exemple a controller.
Signal lines and mains lines must be guided in
different cable channels.
Note
The polarity is arbitrary.

English (GB)

5.2 Checks before commissioning
Check tightness of the total plant before start-up.
– Observe manual of the gas dosing regulators!
5.2.1 Checking the tightness of pressure gas lines
Pressure gas lines are all lines from the gas containers to the
vacuum regulator.
• If the plant is equipped with a nitrogen rinsing device: Check
tightness roughly with nitrogen (all dosing media)
• Detailed checking: with ammonia
5.2.2 Checking the tightness with nitrogen
• Close all container valves
• Open container connection valves and all shut-off valves up to
the gas dosing system
• Open the connection valve of the nitrogen cylinder
• Slowly open the valve of the nitrogen cylinder, until the lines
have a pressure of about 10 bar (read at the manometer of the
vacuum regulator).
• Apply leakage spray or soap water to all components under
pressure
– Formation of bubbles and/or pressure drop at manometer
-->Leakage in pressure lines!
• Depressurize the plant!
• Eliminate leakage!
• Check tightness again!
– No formation of bubbles, pressure at manometer does not
drop significantly within one hour
--> Pressure lines are tight.
5.2.3 Checking the tightness with ammonia
• Open all container valves and container connection valves and
quickly close them again
• Slowly pass the open ammonia bottle along pressure-gas
leading parts
– Formation of white mist: Leakage in pressure lines!
• Depressurize the plant!
• Eliminate leakage!
• Check tightness again!
Fig. 15 Formation of white mist: Leakage in pressure lines!
– No formation of white mist: Pressure lines are tight.
Fig. 16 Pressure lines are tight
Fig. 17 Liquid ammonia makes leakages by corrosion
6. Operation
6.1 Function
• Reducing the gas pressure (overpressure) to subatmospheric
pressure (vacuum)
• In case of too high pressure in the device (e. g. if the inlet
valve is soiled or damaged) the overpressure valve opens.
– Gas will be lead to the absorption vessel.
• In case of the gas container getting empty or blocked gas
supply (too high vacuum in the device) the vacuum shut-off
valve closes.
– Gas containers will not be evacuated with the injector
vacuum.
• Liquid trap (option)
– Prevents liquid gas from getting into the vacuum regulator
– The temperature is self-regulating to max. 60 °C.
6.2 Display Elements
• Pressure gauge (option)
– displays the gas pressure at the inlet (admission pressure)
– optionally with a limit contact for minimal admission
pressure, e.g. empty signal is sent to the control panel.
6.3 Operating
• Observe manuals of the other components.
Warning
Check the tightness not until the total plant is ready
for start-up.
Danger of gas leakage!
Warning
Before checking the tightness:
Start running the optional built-in liquid trap or the
seperate liquid trap!
Danger of gas leakage!
Warning
