  • Page 20 NOTICE Damage due to inadequate installation site The steam generator may vibrate slightly when the water boils. If the wall bearing capacity is insufficient or the wall is of poor quality, the steam generator cannot be securely installed and may fall off. Before installation, check the quality and bearing capacity of the wall intended for instal- lation.

  • Page 21: Mechanical Installation

    5.4 Mounting the steam generator The steam generator is mounted on the wall with four (4) retaining screws and suitable anchors. Note that the steam generator may vibrate slightly when the water boils. Ensure that you have sufficient hardware for securing it if you do not use the supplied screws and anchors. Necessary steps: Preparing for installation Loosen the vaporiser from the shipping plate...
  • Page 22 Loosen the steam generator from the shipping plate 1. CAUTION! Vaporiser and shipping plate weigh approx. 35 kg. Obtain help from a second person.. Lift the steam generator out of the shipping box with the shipping pla- te. Do not pull or hold the device by the plastic housing! 2.
  • Page 23 Mounting the steam generator 1. CAUTION! Generatlr and back wall of housing weigh approx. 28 kg. Two people are needed to mount the unit.

    5.6 Mounting the steam pipe Necessary steps • Connecting the steam supply to the housing floor Hardware + tools: • Ø 35 mm pipe, heat-resistant up to 110°C • T-piece: 1 1/4’’ for steam supply, 3/8’’ for essence nozzle • Silicone, heat-resistant up to 110°C •...
  • Page 28 NOTICE Damage to the steam supply If the injection nozzle for essence is inserted from the side into the vertical pipe or from below into the horizontal pipe, it is possible for essence to dry up before drops of it reach the rising steam. In such instances, a sticky substance can form, which can block the injection nozzle and the pipe.

    6.6 Leakage current The leakage current must not exceed the following values in accordance with DIN EN 60335- 1:2012-10: For stationary class I heating appliances: 0.75 mA or 0.75 mA per kW rated power input of the heating unit, whichever is higher, up to a maximum of 5mA. The electricity supply must be protected by a residual-current-operated protective device (RCD) with a rated fault current of <30 mA.

  • Page 37: Cleaning System

    The approved cleaner is available at EOS as an accessory. The warranty will be void by the use of an unsuitable and unapproved cleaner liquid.
  • Page 38 7.2 Functioning of the cleaning system The 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 evaporated water quantity. They do not depend on the total “switched on” time which may have certain intervals without actual steam production.

  • Page 39: Adjustment Of The Performance

    8. Adjustment of the performance SteamRock II Basic steam generators have a fast-tuning performance that can be adjusted to the cabin size in a few seconds on-site. The switching capacity is set by means of F-fuses (see Fig. 9) on the main terminal block.
  • Page 40 Special attention is required for power increase. If you are unsure which power to select, start with a lower setting first. If necessary, contact EOS Customer Service. CAUTION Risk of scalding from excessive humidity and temperature During commissioning, it must be ensured that the set power matches the cabin size and is not able to generate excessive temperatures in the cabin.

  • Page 41: General Operation

    The SteamRock II Basic does not have an on / off switch. The device is permanently connected to the mains and is switched on and off by an external control by wiring the inputs WB, S1 and N.

  • Page 42: Resetting The Safety Temperature Limiter (Stb)

    9.1 Resetting the safety temperature limiter (STB) The safety temperature limiter (STB) switches off the heater if the vaporiser tank overheats. To restart the heater, you must press the Reset button. CAUTION Risk of burns from hot parts The steam pipe on the base plate is very hot. Do not touch the steam pipe.

  • Page 43: Cleaning And Servicing

    10. Cleaning and servicing The SteamRock II Basic steam generator must be serviced and cleaned regularly. The frequency de- pends on how often it is used. The integrated cleaning and descaling system increases the service life of the steam generator. It does not replace an upstream water softening system, which is re- quired for hard water or if used commercially.
