Electrode wear
Eelctrode wear depends on:
• composition and conductivity of the
supply water
• the amount of steam produced
In case of the electrodes being burned-off to
less than one third to half of their genuine
length, electrode replacement should be
made.
When cylinder water maximum level is
detected for a period of 60 mins, an error
message (s. FlexLine control manual, „Faults
and warnings“ section) is generated and unit
operation is cut. At the latest, electrode
replacement should then be made.
9.6 Leak test
Risk of electrical shock!
Hazardous electrical voltage!
Follow safety instruction for work on live com-
ponents.
Leakages may invoke leak currents.
The leak test described below must be done
after all maintenance work that affects the
water circuit inside the unit. If work has been
done at several points, the final leak test is
enough, although this work step is listed for
all parts of the work.
The leak test must be done with the unit
open, paying particular attention to the warn-
ing above.
» Open the water supply.
» Switch on the unit and check the
inside for leaks (hose connections,
O-rings, seals) after 15-30 minutes
of operation.
» In case of leakage turn off power
supply and secure against being
switched on again.
» Find leakage and eliminate.
» Check again.
» Follow the instructions in the section
funktional check.
9.7 Functional check
» Run the system with maximum out-
put for a couple of minutes
» Check hose connections and seals
for leakage.
