Descaling
Part of the limescale accumulated in the steam generator is flushed away during the automatic flushing and rinsing
cycle, but some of it will remain. Therefore it is important that the steam generator's automatic flushing function is not
out of order due to faulty electric connection. The tank must be flushed after every use.
To prolong its service life and to reduce the need for manual descaling we recommend that steam generators
used in public facilities are connected to a water softener, which removes the calcium. This is especially
important if the water hardness exceeds 4° dH (German hardness).
The water softener must not generate foam or produce harmful chemicals, which may give erroneous view of the
water level in the tank and cause the temperature switch to trip. (Heating elements will break down after some time.)
Manual descaling should be performed according to the chart below.
In normal private use, the need for descaling is minimal if the water is not particularly hard. However, the steam
generator must be descaled at least once a year. This removes the limescale from the tank walls and heating
elements.
Warning: The inlet pipe nut may be hot.
Steam generator descaling
•
Start the steam generator and let it run until the water in the tank boils.
•
Stop the steam generator and wait for about 5 minutes.
•
Remove the connecting piece's lid nut at the top of the steam generator.
WARNING: The nut on the lid might be hot – risk of burning.
•
Pour the descaling agent (e.g. citric acid) into the tank via the connecting piece using a funnel.
•
Attach the lid nut to the connecting piece and let the agent work.
•
The steam generator flushes and rinses the tank automatically after about one an hour, after which you can
use the steam generator again.
Citric acid is an odourless and harmless descaling agent and it does not harm the steam generator's components.
If any other type of descaling agent is used, you must not bathe during the descaling procedure.
As can be seen from the adjoining chart, the need for manual descaling depends on water quality, steam generator
output and operation time.
Operation time in hours before descaling is required. A water softener must be used in public facilities
to reduce the need for manual descaling. In addition, the automatic flushing valve (Automatic Drain
valve) must be used.

Cleaning the steam room
Rinse the seats and the floor with warm water after every use (do not use a pressure washer). Clean the seats
regularly with mild detergent Use ethyl alcohol or dilutine. Never use abrasives, strongly alkaline detergents or
solvents to clean the steam room seats and walls. Contact the manufacturer if necessary.
It is important to clean the floor carefully all the way to the corners. Use hot water, a brush and floor detergent that
removes dirt and grease.
