5.2 Connecting the vacuum regulator

Warning
Before connecting, make sure that the valves of all
chlorine containers are closed.
The vacuum regulator has to be operated in the
chlorine room.

1. Position chlorine containers and protect them from turning
over or rolling away.
2. Clean and dry the connections, if necessary.
3. Remove the protective cap from the container valve.
Warning
Replace the gaskets of the pressure connection at
any change of container.
Use the filter at the pressure connection.
4. Insert the gasket at the pressure connection of the vacuum
regulator.
– Replace the filter at the pressure connection, if necessary.
Do not align the device by turning the housing.
Caution
If necessary, hold up with a 13-mm fork wrench.
5. Mount the regulator onto the container connection.
Warning
Lead the overpressure line downwards, and into a
suitable adsorption filter.
If using a gas warning device, install the sensor at a
maximum distance of 10 cm below the outlet hole of
the adsorption filter.
6. Connect the overpressure line (2) to the adsorption filter.
For the selection of the lines, see section

lines.

5.3 Connecting the liquid trap (option)

Make sure that the mains voltage indicated on the
name plate corresponds with the local voltage.
Wrong voltage can lead to damages of the product.
Signal lines must be shielded to ensure
Caution electromagnetic compatibility (EMC).
The shield must be connected to PE or ground on the
side of the counterpart, e.g. a controller.
Signal lines and mains cables must be guided in
different cable channels.
Connect the mains cable of the liquid trap and the optional
contact pressure gauge with the mains. Connect the contact
pressure gauge with the evaluation device. Observe the polarity.
