7.2 Setup and operation of the cleaning system
Steamtec II Basic steam generator features an integrated automatic descaling and draining system.
This system will automatically descale the water tank at certain intervals. These intervals depend
on the effective working time (heating time of heating elements) and the pre-set water hardness
level. They do not depend on the total “switched on” time which may have certain intervals with-
out actual steam production. After the descaling the water tank will be rinsed and drained. High
pressure blast of water directed at the drain will help to split scale flakes into smaller pieces and
clear them out of the tank during the draining.
The descaling cycle will start if the calculated time interval for cleaning is reached and the steam
generator remains idle (no steam production) for 45 minutes. This is interpreted as the end of the
steam operation session and the cleaning cycle may start.
In the case the steam generator is operated in a manual non-stop mode a forced descaling cycle
will be carried out after 24 h of operation.
The descaling cycle will be also started if the steam generator has reached the calculated time for
cleaning and has been disconnected from power and then connected to power again.
In the case if the calculated time for the next descaling has not yet been reached but the gener-
ator has been stopped for 45 minutes it will consider that the operation session is over and will
drain the water tank. This will take approx. 10 minutes time.
If this feature is not desired it may be disabled. To disable or enable this feature:
•
Open the steam generator and disconnect the power supply.
•
Remove the jumper JP2 from „A“ position.
•
Set the jumper JP1 to „H“ and „S“ (use the spare jumper removed
from JP2).
•
Switch on the power supply.
•
The „Status LED“ on the main board will flash
- two times if the draining function is enabled
- three times if the draining function is disabled
•
Disconnect the generator from power
•
Set the jumper JP2 back to „A“ position, set the jumper JP1 to
the desired water hardness level (see below), switch the power
supply to the steam generator.
The setting of the water hardness is made with the jumper JP1 on the
main board of the generator. During the active descaling cycle the “pilot
lamp” with be flashing twice.

Descaling interval
Descaler consumption
H - hard water
5 hours of heating time
~ 400 ml
M - middle hardness
5 hours of heating time
~ 200 ml
S - soft water
10 hours of heating time
~ 200 ml
I - instant descaling
Makes instant forced cleaning with ~ 200 ml cleaner. Make sure to
set the jumper back to H, M or S position after the cleaning cycle.
