OPERATING INSTRUCTIONS

TO TAKE THE SHOWER FOR THE USER

IMPORTANT!
THE HEATER TANK MUST BE FILLED UP WITH WATER BEFORE TURN ON THE ELECTRIC SUPPLY THIS IS TO PREVENT ANY DRY BURNT DAMAGE TO THE HEATING ELEMENT.
SHOULD TURN OFF THE HEATER BEFORE TURN OFF THE Product water supply valve.

Starting

1. Turn on the main product water supply valve.

2. Switch on the electric supply on the main switch out of the shower:

   • a. It enables the SAFETY CHECK technology to run a system scan of the product for 4 sec. and the SAFETY CHECK led will blink:
   1. If everything is running smoothly and safely the SAFETYCHECK and ELCB led will be steady.
   2. If the SAFETY CHECK led continues to blink, it is because SAFETY CHECK technology has de-tected some failure and the user has to switch off the main supply and contact the service agent for repair.

3. Turn on the product water supply valve on the product to clockwise until the water flow through the shower head.

4. Rotate the control knob, the HEATING led will light up and hot water will start flowing from the shower head.

5. Adjust the shower condition setting by:

   • a. Rotate the control knob in clockwise to increase the temperature or in anticlockwise to de-crease the temperature;
   • b. Turn the product water supply valve in clockwise to increase the water flow decreasing the outlet water temperature or turn it in anticlockwise to decrease water flow increasing the outlet water temperature;
   • c. In rare case if inlet water is too cold, both options can be not enough to reach the desired shower conditions.

6. Temperature setting (fig. 2) AURES PREMIUM

   • a. Rotating the control knob the user gradually regulates the Power setting to find the desired shower condition:
   1. Rotating clockwise the control knob the power gradually increases and the shower tem-perature will go up., at “MAX” position the hottest outlet water;
   2. Rotating anticlockwise the control knob the power gradually decreases and the shower temperature will go down, at “OFF” position, the water temperature will remain at inlet temperature;
   3.  In case some external factors (i.e. Inlet temperature, Inlet water flow, electricity fluctuation) change, the product will not modulate the power and outlet temperature will be impacted increasing or decreasing depending on the external changing.
      AURES PREMIUM+

   • a. Rotating the control knob the user gradually sets the Temperature to find the desired shower condition and on the display he reads the temperature is going to set ;

   • a. Rotating clockwise the control knob the temperature gradually increases, reaching 45°C at “Max” position;
     b. Rotating anticlockwise the control knob the temperature gradually decreases till 32°C at “Min” position. At “OFF” position, the outlet temperature will remain at inlet temperature;

   • c. In case some external factors (i.e. Inlet temperature, Inlet water flow, electricity fluctuation) change, the product will modulate the power so that outlet temperature will remain con-stant at setting temperature, guaranteeing the highest and stable comfort.

7. Select the preferred shower jet thanks to spray position lever on the shoer head.
