Maintenance
The system
switches off after
60 min. in opera-
tion in cylinder full
condition.
•
Unit requires maintenance:
- Cylinder full of scale deposits wich limit the
electrodes immersion depth.
- Electrodes worn out.
•
•
Clean steam cylinder and elec-
trodes or replace electrodes.
Replace electrodes. (If electrode
wear is high, see note in section
„Electrode Exchange“ in unit hand-
book)
•
Phase defective (external fuse faulty).
•
Replace fuse.
•
With very low water conductivity continuous
steam production is insufficient in order to
concentrate and raise the water conductivity.
•
Establish water values and/or con-
tact HygroMatik about the problem.

Maintenance K1
The system still op-
erates. The green
LED flashes rapid-
ly.
•
According to manufacturer specification 90%
of the electrical lifetime is achieved. To avoid
failure, a replacement of the main contactor is
recommended in the short term.
•
•
Replace main contactor.
See parameter description "P11 re-
set main contactor interval" for
Comfort / Comfort Plus control or
"Brief Description of Jumpers" for
Basic control..

•
By opening and closing the safety
interlock the steam generator
restarts operation for the pro-
grammed hours (D5).
Alternatively set parameter D5 to 0
and restart system. The function
