Removing the electrode
Installing the electrode
1st
Loosen the Allen screw (1) and remove the cover.
1st
Insert the new electrode (5) into the retaining cylinder
(7) from below. Make sure that the seals at the tip of
the electrode are clean.
2n
d
Remove the electrode cable (2) secured to handle (3).
2n
d
Mount the handle (2) on the electrode and insert the
locking pin (8) to secure it in position.
"
Caution!
Make sure that coil spring (11) is inserted. This is
essential to ensure correct electrical contact and
correct measuring signals.
3rd Loosen knurled nut (4) by hand. This knurled nut acts
as a locknut.
3rd Pull the electrode back until the tip of the electrode
no longer protrudes from retaining cylinder (7).
4th Remove the electrode (5) by turning the handle (2).
The electrode can now be pulled out of the retaining
cylinder (7) as far as a defined stop.
#
Warning!
Risk of injury. Under process conditions (pressure in
the piping system) the electrode can recoil suddenly
against its stop. Apply counter-pressure while
releasing the electrode.
4th Screw the retaining cylinder (7) onto the ball-valve
housing (9) and tighten it by hand. The seal (10) on
the cylinder must be correctly seated and clean.
!
Note!
Make sure that the rubber hoses on the retaining
cylinder (7) and stop cock (6) are of the same color
(red or blue).
5.
Close the stop cock (6) after pulling out the electrode
as far as it will go.
#
Warning!
Do not subsequently open the stop cock, in order to
prevent fluid escaping.
5.
Open the stop cock (6) and turn the handle (2) to
screw the electrode all the way into the retaining
cylinder.
6.
Remove the electrode complete with
retaining cylinder (7).
6.
Screw the knurled nut (4) onto the
retaining cylinder. This firmly locates the electrode in
position.
7.
Remove the handle (2) from the electrode (5) by
pressing out the locking pin (8). Take care not to lose
the coil spring (11).
7.
Use the Allen screw to secure the electrode cable (3)
to the handle (2).
"
Caution!
Make sure that the machine screw securing the
electrode cable is firmly tightened. This is essential to
ensure correct electrical contact and correct
measuring signals.
8.
Remove the old electrode and insert the new
electrode. Replacement electrodes can be ordered
separately from Hauser.
8.
Reinstall the cover and tighten the Allen screw (1).
