Removing the electrode
Installing the electrode
1
Loosen Allen screw (a) and remove the cover.
1
Insert new electrode (e) into retaining cylinder (g)
from below. Make sure that the seals at the tip of
the electrode are clean.
2
Remove electrode cable (c) secured to handle (b).
2
Mount handle (b) on the electrode and insert
locking pin (h) to secure it in position.
"
Caution!
Make sure that coil spring (k) is inserted. This is
essential to ensure correct electrical contact and
correct measuring signals.
2
Loosen knurled nut (d) by hand. This knurled nut
acts as a locknut.
2
Pull the electrode back until the tip of the electrode
no longer protrudes from retaining cylinder (g).
3
Remove electrode (e) by turning handle (b).
The electrode can now be pulled out of retaining
cylinder (g) 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.
3
Screw the retaining cylinder (g) onto ball-valve
housing (i) and tighten it by hand. Seal (j) on the
cylinder must be correctly seated and clean.
!
Note!
Make sure that the rubber hoses on retaining
cylinder (g) and stop cock (f) are of the same color
(red or blue).
4
Close stop cock (f) 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.
4
Open stop cock (f) and turn handle (b) to screw the
electrode all the way into the retaining cylinder.
5
Remove the electrode complete with retaining
cylinder (g).
5
Screw knurled nut (d) onto the retaining cylinder.
This firmly locates the electrode in position.
6
Remove handle (b) from electrode (e) by pressing
out locking pin (h). Take care not to lose coil
spring (k).
6
Use the Allen screw to secure electrode cable (c) to
handle (b).
"
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.
7
Remove the old electrode and insert the new elec-
trode. Replacement electrodes can be ordered
separately from Hauser.
7
Reinstall the cover and tighten (a) Allen screw.
