Rational CombiMaster Plus User Manual

Building services - steam generator descaling
90 / 107
The steam generator must be descaled manually on a regular basis.
We recommend the following descaling intervals
based on 8 hours’ steaming per day:
- up to 18 °dH (to 3.2 mmol/litres) at least 1x annually
- up to 24 °dH (to 4.3 mmol/litres) at least 2x annually
- over 24 °dH (to 4.3 mmol/litres) at least 3x annually
These recommended descaling intervals may vary from the approximate values given above,
depending on the composition of the water (e.g. minerals).
You need:
Electric descaler pump - article no.: 60.70.409
Descaler, 10 litre canister – article no.: 6006.0110
Heavier limescale deposits in the steam generator can only be removed by the Service
Technician.
If the steam generator has a heavier build up of limescale, the "Calc Infor" function will be
displayed at the end of the CleanJet
®
cleaning programme.
You can find more information on this in the descaling display sub-section in this operating
manual.
