(7) After completion of the functional test or when changing the bottle:
– Close the shut-off valve on the pressure reducing device.
– Separate the pressure reducing device from the interstitial space (testing device).
– Close the bottle shut-off valve.
– Open the shut-off valve on the pressure reducing device (pressure reducing device be-
comes pressure-less)
– Dismount the pressure reducing valve from the bottle.
– Replace the protective hood on the bottle.
5.7. Electrical
connection
(1) Voltage supply according to information on type plate.
(2) Firmly laid, i.e. no plug or switch connections.
(3) The regulations of the electrical supply company must be heeded
.
(4) Terminal connection: see Technical Data sheet.
5.8. Assembly

6. Putting into operation / service
6.1. Basic
instructions
(1) Assembly according to chapter 5, instructions given in that chapter must also be heeded
here.
(2) The interstitial space must be flushed with inert gas if the wall coming into contact with the
stored medium is not impermeable.
(3) Should a leak detector be put into operation on a pipe which is already in operation, special
protective measures must be taken (e.g. check there is no gas in the leak detector and / or
interstitial space). Further measures can depend on local conditions and must be evaluated
by the operating staff.
(4) Once the pneumatic connection has been made, make the electrical connection.
(5) Make sure the "in operation" and "alarm" lamps are lit up and the acoustic alarm is working.
Then switch the "acoustic alarm" switch off.
(6) If the factory settings cannot be taken over, proceed with chapter 6.2
(7) Build up the pressure using the device according to drawing P-115 520
