7. Maintenance information
7.1
General information
Maintenance of the Sanoasa Wellness Multicentre shower cabin is
essentially restricted to regular descaling of the steam generator.
All other devices are maintenancefree. The Sanoasa Wellness Mul-
ticentre cabin must be disconnected from the mains supply when
performing any maintenance, installation or repair work. This is
done using the master switch, which is located underneath the
steam generator. Before carrying out any sanitary work on water-
carrying components, they must be disconnected from the water
system (unpressurised). Work on the cabin must be indicated by
means of a well-positioned and legible sign. The operator is respon-
sible for these measures.
7.2
Steam generator
The steam generator features an automatic draining function. This
stops if there is any type of power failure. This automatic function
significantly reduces limescale deposits and contamination in the
water reservoir. To ensure the automatic draining and rinsing will
work, a switch possibly located between the fuse box and steam
generator can be switched off at the earliest 80 minutes after the
timer is triggered on the control panel.
7.3
Descaling the steam generator
Descaling must be carried out regularly according to the table on
the right. This removes limescale deposits from the walls of the
container and from the heating elements. Regular descaling ex-
tends the service life of the steam generator. If descaling is not
regularly carried out in accordance with the table listed under Sec-
tion 5.3.1, the steam generator will very quickly become damaged
and the device cannot be repaired. It is recommended to install a
water softener in areas with hard water, i.e. above 5° dH (German
hardness).
Procedure for descaling:
1.
Unscrew the cap nut at the top of descaling pipe no. 1.
2.
Start the steam generator and let it run until the water in the
container is boiling.
3.
Switch off the steam generator and wait approx. 5 minutes.
4.
Dissolve the descaling powder in 200 ml warm water (approx.
30 minutes) and, with the help of a funnel, pour into the cop-
per pipe and rinse down with approx. 300 ml water.
5.
Screw the cap nut on to the copper feed pipe and tighten.
Allow the descaling agent to take effect.
6.
After approx. 1 hour, the container is automatically drained
and rinsed and the steam generator can be operated again.
Maximum running time before descaling:
As the following table shows, the requirement for manual descal-
ing depends on the water quality and running time:
If the steam bath is only used rarely, it is recommended to descale
the bath generally at least every three to four months.
