11. Maintenance and servicing
The steam generator requires regular maintenance depending on the intensity of use. The integra-
ted automatic descaling system increases the service intervals and reduces the maintenance cost,
however it does not make the steam generator maintenance-free.
!
WARNING
Risk of damages to persons and to the device.
•
The steam generator has hot surfaces, e.g. pipelines, water tank,
which may cause burns
.
•
Maintenance may be carried out by an authorized and appropri-
ately skilled personnel.
•
Disconnect the steam generator from power before any mainte-
nance and servicing works.
•
Make sure to observe servicing intervals as given below.
•
Request an assistance from EOS or an authorized EOS dealer by
any questions.
Recommended servicing intervals
•
By domestic use - at least once per year.
•
By commercial use - at least twice per year or more if necessary depending on the situation,
water quality and intensity of use.
Scope of works for regular servicing:
•
Check condition of all connection tubes, clean if necessary
•
Check condition of the drain, remove scale deposits and clean if necessary
•
Check the overheating temperature limiter fuse (visual condition and secure fastening)
•
Check the level of the descaler liquid, replenish if necessary
•
Check condition of the tube in the descaling pump, replace if necessary (by wear-out traces)
•
Remove the water level prove, check condition and clean if necessary. Re-installed, check
the correct height (page 18).
•
Opening the water tank is normally not necessary. If there is an indication that there are
limescale deposits inside the water tank it may be opened for mechanical cleaning. Check
condition of the inner surfaces, remove limescale if necessary. By excessive limescale
deposits check if the set water hardness level is sufficient and if the pre-installed water
softening system is effective. If no water softening system is available it may be required to
be installed. Before closing the water tank check condition of the silicone sealing gasket. The
gasket needs replacement if worn out or damaged.
