1. The steam generator will be ready to use immediately after lime removal If you detect a lemony aroma in the steamroom after lime removal flush the steam generator again Citric acid is not harmful to the health STEAM GENERATOR FOR PROFESSIONAL USE In addition to lime removal we recommend drafting a service plan for steam generators which are in daily use 5 or more hours The steam generator should be serviced at least 2 times a year including a visual inspection and cleaning of the resistors and surface level sensor as well as an inspection and cleaning of the tank interior lime deposits Replace parts wherever necessary The tank is cleaned through the resistor mounting holes 152. When the fault alarm is given the steam generator will shut down Repair the cause of the fault or call an authorised service technician Malfunctions can be reset by pressing the ON OFF button In button equipped versions the button LED will flash rapidly when the fault is detected the steam generator is running when the water faucet is shut or for some other reason water is being prevented from flowing into the steam generator This alarm is also given when the water feed is cut while the steam generator is running The malfunction can be reset by pressing the button Repair or replace the cause of the fault The circuit board output for an external alarm is 12 V DC max 50 mA The output is activated when alarm El or E2 is displayed or the LED flashed rapidly The alarm is reset by pressing the ON OFF button 13 HSX STEAM GENERATOR SERVICING PROCEDURES The HSX steam generator has a programmed automatic function which drains and rinses the tank after each use The electrically operated drain valve is an accessory A long service life is also achieved by emptying the steam generator tank immediately after use in areas where the water is perhaps not of the best possible quality However draining the tank is not an alternative for the regular removal of lime from the tank It is also worth cleaning the surface sensor at times These procedures should be undertaken either by a service centre or some other professional person Testing water qua
