6.6 Leakage current
6.7 Special advice for water quality
Please make sure to observe the DIN EN 60335-1:2012-10 norm in respect to the leakage current.
This norm requires that the leakage current may not exceed the following limits at the normal
operating temperature:
“For stationary class I heating appliances - 0,75 mA or 0,75 mA per kW rated power input of the heating
appliance with a maximum of 5 mA, whichever is higher.”
The electricity supply must be protected with a residual-current-operated protective device (RCD)
with a rated fault current <30 mA. Please make sure that no other electrical appliances are protect-
ed with this RCD device.
The applicable international, national and local legal norms and requirements (e.g. VDE, EU regula-
tions) in their currently valid version should be observed. All installation and testing works should
be carried out by a licensed and appropriately qualified electrician with the respect to the men-
tioned norms and codes (e.g. VDE 0100 part 701). All works may be only carried out when the
steam generator is completely disconnected from power.
Important Notice:
Water supplied to the steam generator may be contaminated with so-called plasticis-
ers or similar substances which are able to modify the surface tension of water in the
water tank.
This may cause strong foam building during water boiling. Boiling water may be
spilled into the steam pipe or it may cause the generator to measure the water level
incorrectly and lead to overheating and tripping of the limiter fuse.
Please ensure that water supply to the steam generator is free from plasticisers.
Plasticisers or similar substance are for instance contained in essence oils and fra-
grances, certain cleaners and chemicals. They may get in water from PVC pipes and
tubes. It must be ensured that the entire water supply line does not contain materials
containing plasticisers
.
