Mounting and preparation/Venting the system
GB
Mount the shut-off valve (3) in the surface mounting flange at the side of the pump
■
in exchange for the screw plug mounted as standard. During this process the pump
must be free of pressure (see chapter 6. Mounting instruction).
Mount the test specimen (4) on the test connection.
■
Mount the reference instrument (5) on the second test connection.
■
Put the reservoir cap back on and fit the shut-off valve (2). However, leave the valve
■
open!
Close the shut-off valve(s) for test connections (3) by turning them clockwise.
■
Turn the star handle anticlockwise until fully out/open.
■
1) Close the shut-off valve on the reservoir (2).
2) Open the shut-off valve(s) for test connections (3) by turning them counterclockwise
(less than one complete turn is suffi-cient).
3) Turn the star handle (1) clockwise until the test specimen and/or the reference
indicates a pressure of appro. 50 to 100 bar.
4) Fully open the valve (2), slowly and carefully. If necessary, check again if any air
bubbles escape.
5) Close the shut-off valve on the reservoir (2).
6) Close the shut-off valve(s) for test connections (3) by turning them clockwise.
7) Turn the star handle anticlockwise all the way out.
Repeat steps 1) to 7) several times.
■
Operation
Open the shut-off valve (3) on the test specimen and close the shut-off valve on the
■
reservoir (2).
Turn the star handle clockwise. Operating liquid is pressed into the connected test
■
specimen.
If the connected instrument has still not been filled enough or if the required pres-
■
sure has still not been reached, close the shut-off valve on the test specimen (3).
Open the shut-off valve on the reservoir (2) and turn the star handle counterclock-
■
wise as far as it will go. New pressure medium is drawn from the reservoir into the
cylinder of the pump.
Close shut-off valve on the reservoir (2).
■
Open shut-off valve on the test specimen (3).
■
Turn the star handle clockwise again.
■
Repeat the process described here until the required pressure is reached.
