OVERPRESSURE – LEAK DETECTOR DL ..
(7) Seal conduits to be gas-tight with protection from penetration of liquids.
(8) Avoid build-up of static electricity (e.g. when inserting and routing tubes).
(9) Details for connecting systems, see worksheet AB-820 500
4.5 Installation of the dry filter (DL .. ONLY)
(1) As close as possible to the leak detector. If the leak detector is mounted in a protective
box, the dry filter can be installed in the protective box or in the open air.
(2) Vertical with intake opening at the bottom, using enclosed installation material.
(3) Connect the dry filter to the leak detector intake port with a PVC hose (or similar).
4.6 Choice of pressure reducer (DLG ..ONLY)
(1) The pressure reducer must have an integrated overpressure valve.
(2) The range for the pressure reducer must be selected according to the specific application
respectively adjusted pressure (see Annex B).
4.7 Pressure cylinder and pressure reducer (star up/function test) (DLG .. ONLY)
(1) After the pressure cylinder has been set up securely, remove the protective cover.
(2) Fit the pressure reducer to the cylinder.
(3) Close the shut-off cock on the pressure reducer.
(4) Install the connecting tube between leak detector and pressure reducer.
(5) Turn pressure control valve all the way back.
(6) Open bottle shut-off cock (poss. leak test between pressure reducer and bottle)
(7) Adjust pressure at pressure reducer as per Annex B using pressure control valve on
pressure reducer (poss. readjust during pressure build-up).
(8) To change the pressure cylinder:
-
Close the shut-off cock on the pressure reducer.
-
Close the bottle shut-off cock.
-
Remove the pressure reducer from the cylinder (caution: gas escapes until pressure is
relieved in the pressure reducer)
-
Put protection cover on the cylinder.
-
Erect and secure new cylinder, remove protection cover.
-
Fit the pressure reducer (poss. leak test between pressure reducer and cylinder)
-
Open bottle shut-off cock.
-
Open shut-off cock on pressure reducer, poss. readjust pressure using the pressure
control valve.
