stallation)
Removal
»
Shut off water supply and disconnect
tap water hose cap screw connection.
»
Remove connecting hose (20*) from
cylinder base.
»
Detach electrical cable connector
from solenoid valve (25*).
»
Unscrew solenoid valve mounting
screws.
»
Remove solenoid valve from hous-
ing bore.
Reinstallation
»
Reinsert fine filter into solenoid valve.
»
Reinsert solenoid valve with seal in
unit housing bore.
»
Bolt-down solenoid valve.
»
Reestablish tap water connection.
»
Reconnect electrical cable to sole-
nod valve.
»
Reattach connecting hose (20) to
cylinder base using clamp.
»
Follow the handling instructions in
the section
Leakage test.

named chapter
9.4.3 Electrode replacement
»
Remove the cylinder and open it
(see also chapter Removal of the
steam cylinder).
When mounting the electrodes, make sure
that the hand nut colours corresponding with
the wiring colours remain in the same posi-
tion as before in order to omit any unwanted
shift of electrical potential. Hence, the hand
nut positions must be recorded before they
are removed. During reassembly, particular
care must be taken to ensure that no grey
wire is connected to the electrode plug next
to the (grey) sensor electrode hand nut.
»
Unscrew hand nuts (A).
»
Remove electrodes (B).
»
Install new electrodes (48). Make
sure that the electrodes are posi-
tioned correctly (see exploded view)
»
When installing the new electrodes,
make sure that there is a new o-ring
in the cup-like holder.
The electrodes for use with the CY45/2
steam cylinder feature a two-fold sealing (s.
following fig.) In order to allow for the prob-
lemfree electrode installation, moisten the
upper o-ring with water or soap solution.
