4.1.3 Connecting the VGA-117 dosing regulator to the vacuum
lines
WARNING
Toxic material
Death or serious personal injury
‐
Before starting to connect, make sure that the valves
of all chlorine containers are closed.
Only tighten the union nuts of the vacuum connections by
hand. Do not use any tools.
Make sure that the vacuum connections are clean and
dry.
The dosing regulator can be installed outside the chlorine room.
1. Connect the dosing regulator to the line from the vacuum
regulator (5).
2. Connect the line (3) from the dosing regulator to the injector.
• VGA-117 with differential-pressure regulator: Connect the line
from the differential-pressure regulator to the injector.

4.2 Electrical installation
WARNING
Electric shock
Death or serious personal injury
‐
Before making any electrical connections, switch off
the power supply and make sure that it cannot be acci-
dentally switched on.
‐
All electrical connections must be carried out by a
qualified electrician in accordance with local regula-
tions.
‐
All electrical connections must be carried out in ac-
cordance with the wiring diagram.
Before connecting the mains cable, make sure that the
voltage and frequency specified on the nameplate corre-
spond to the local power supply.
An incorrect supply voltage may destroy the device.
Route the input, output and power supply cables in sepa-
rate ducts.
Read the separate supplier manual of the respective ser-
vomotor. Find the QR code on the nameplate of the servo-
motor.
5. Startup
WARNING
Toxic material
Death or serious personal injury
‐
Startup must be carried out by authorised and trained
experts.
‐
Observe the material safety data sheets (SDS) of the
handled chemicals.
‐
Wear personal protective equipment when handling
chemicals.
For startup, all components of the entire system must be
ready for operation.
Observe the manuals of the system and all other compo-
nents.
5.1 Checks before startup
Before startup:
•
Check the electrical connections.
•
Check the mechanical installation.
•
Check the tightness of the entire system.
5.1.1 Checking the chlorine solution lines and the injector
Observe the installation and operating instructions of the
injector.
5.1.2 Checking the tightness of the pressure side
Observe the installation and operating instructions of the
vacuum regulator.
5.1.3 Checking the tightness of the vacuum side
Make sure that the pressure side of the chlorine gas dos-
ing system is tight.
Make sure that the injector is ready for operation.
1. Close the connecting valves of all drums or cylinders.
2. Start the injector.
3. Slowly open the adjusting valve at the dosing regulator.
The vacuum lines are evacuated.
After about 10 minutes, depending on the length of the vacuum
lines, the dosing regulator indicates no flow.
If the dosing regulator indicates a flow, the complete system must
be checked for leaks.
Checking the system for leaks
1. Disconnect the vacuum lines between the vacuum regulators
and the dosing regulator one after the other.
2. Close each disconnected line tightly.
If the dosing regulator stops indicating a flow, the last disconnected
component is leaky.
Repair or exchange the leaky component and check the tightness
again.
