3. Safety notes Installation, initial operation and maintenance of this appliance must only be conducted by an authorised professional, who will then be responsible for adherence to applicable standards and installation regulations. We assume no liability for any damages caused by failure to observe these instructions.
4. Intended use, operation If the flow rate is too low, if the flow pressure is too low, or if the warm-water valve is closed, the appli- ance switches itself off automatically. For an optimum flow of water, always fit the special jet regulator enclosed with the appliance. This regulator is screwed into the thread on the end of the tap. If the thread of the chrome-plated sleeve does not fit your tap, you can insert it into any standard sleeve M22/24. The maximum possible outlet temperature is determined by the temperature of the incoming water, the rate of flow and the heating power of the heater. The flow rate can be preset inside the appliance to achieve the selected temperature between about 30 °C and 50 °C.
6. Installing the appliance Abb. 1 fi g. 1 Abb. 2 fi g. 2 fi g. 2 • Secure the wall bracket to the wall with screws and suitable wall plugs (see fig 1). • Place the appliance on the wall bracket and snap it into position (see fig. 2). • The appliance is good for undersink and oversink installation according to the examples of installation on the next pages. For undersink installation the water connectors must point vertically upwards. • Pipe connection (see fig. 3): Cold water inlet (blue) and hot water outlet (red) are marked on the rat- ing plate. Connect the appropriate pipes from the tap to the water inlet and outlet accordingly. Avoid exerting any kind of mechanical pressure exerted on the appliance, e.g. by water pipes etc. • After installation, carefully check all connections for leaks and rectify as necessary. In order to obtain an optimum water jet at low flow rates, always screw the enclosed jet regulator onto the tap outlet. This insert fits commercially available sleeves with an M22 or M24 thread. seal strainer seal cold water connection (inlet) hot water connection (outlet) fi g.

8. Electrical connection Fill the appliance completely with water by repeatedly opening and closing the hotwater tap before connecting to electrical power. The heating element may be damaged if this is not done! • The installation must comply with current IEC regulations and national local regulations and any par- ticular regulation, specified by the local electricity supply company! • The mains cable must be permanently connected via connecting box as shown in the circuit diagram.
9. Adjusting the water flow and temperature The maximum outlet temperature can be set between about 30 °C and 50 °C with the potentiometer (Fig. 7), adjustment only by a professional. The factory setting is about 45 °C. Turning the potentiometer clockwise reduces the Min. maximum outlet temperature; turning it counter- Temperature clockwise increases the temperature. adjustment During use, the red LED on the printed circuit Max. red LED board lights if the maximum power of the heater green LED cannot achieve the preset outlet temperature.
10. Commissioning Do not switch on the electric power at this time! 1. Open the hot water tap and allow water to flow until it emerges free of air bubbles. 2. Now close the circuit breaker to connect the electrical supply. 3. If desired, set the desired outlet temperature inside the appliance (see Fig. 7). 4. Explain the functions of the heater to the user and ensure that he knows how to use it. Hand over these operating instructions to the user. 11. Technical specifications Type GPIM7 Art.

Purging To prevent damage to the appliance, the instantaneous water heater must be purged from air before using it for the first time. Each time it is emptied (e.g. after work on the plumbing system, if there is a risk of frost or following repair work), the appliance must be purged from air before it is used again.
