6.6 Leakage current 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.”...
7. Cleaning system 7.1 General information Steamtec II Basic steam generator is equipped with an automatic descaling and draining sys- tem. Included with the delivery is a 5 l container for cleaning liquid (cleaning liquid not includ- ed, optional accessory) with the level probe.
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.
8. Power selection Steamtec II Basic steam generator features adjustable power output, which allows to quickly set the required power output directly on site and to adjust it later if required. The power output selection is made by F-fuses (switches) on the main terminal rack of the steam generator.

Steamtec II Basic 9 kW). By Steamtec II Basic 18 kW it is possible to reduce the heating power dur- ing this phase to 6 or 3 kW by switching off fuses F2 and F3. By Steamtec II Basic 9 kW the basic power is always 3 kW only.

Once the room temperature falls below the low hysteresis point an external switching signal will be normally given to Wb terminal and the steam generator will start heating will all enabled heating elements. For safety reasons if no external switching signal is given for 30 minutes the steam generator with completely stop (continuous steam production phase will stop).
10. General operation The Steamtec II Basic steam generator does not have an own on/off switch and remains always connected to power supply. The steam production is switched on or off from an external control unit (switching signal on input terminals Wb, S1 and N). An external control unit does not belong to the delivery scope of the steam generator and shall be purchased separately.
Disconnect the steam generator from power before any mainte- • nance and servicing works. Make sure to observe servicing intervals as given below. • Request an assistance from EOS or an authorized EOS dealer by • any questions. Recommended servicing intervals •...
Remedy: Check the drain, make sure it is not blocked by scale and other deposits. If the drain is clean and motorized ball valve does not appear to function please contact your EOS dealer for assistance. The ball valve or the actuator may be faulty.
Fault: No descaler liquid (pilot lamp flashing 3 times) Remedy: Replenish the descaler liquid container. Make sure to use the suitable type of descaler. Check the level probe for lose connection and verify it is connected properly. General fault: Overheating limiter fuses releases occasionally. Remedy: Increase the water filling level in the water tank by pulling the water level probe up to1 - 2 cm up.
