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.
Warning
Ensure that all container valves are closed before
mounting.
Only use the intended line types!
In case of design without mounting plate:
The device will only be carried by the connection with
Caution the pressure line.
Ensure that all piping is free of distortion.
Do not mount the device in a distorted manner.

5. Commissioning

5.1 Preparations for commissioning

5.1.1 Vacuum connections

Warning
Before connecting, ensure that the valves of all gas
containers are closed.
Only use the intended line types!
Only tighten the union nuts of the vacuum
connections by hand. Do not use any tools!
Caution
Danger of damages!
Maximum length of the vacuum line, see chapter
2.7 Recommended diameter
• At the vacuum regulator, connect the vacuum line and connect
it to the dosing regulators.
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!
• Connect the overpressure line to the overpressure connection.
• Connect the vacuum line to the injector.

5.1.2 Pressure line connection

Ensure that the pressure lines are as short as
Note
possible.
• Slightly apply grease to the gasket, if necessary
• Connect the pressure line to the pressure line connection

5.1.3 Electrical connections

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):
Caution
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.
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
Note The polarity is arbitrary.
