First start-up Electrical connection ■ Important: Do not insert the plug into the mains socket yet. ■ Fill the appliance with water first. Water must flow from the fitting. ■ Only then insert the plug into the mains socket. Note: If the appliance is not filled with water, the resettable safety temperature limitation will trip! Checking the heating ■ Turn the rotary selector switch to “III” (approx. 85 °C). ■ Monitor the heating process until the pilot lamp switches off after approx. 12 ‒ 18 minutes. ■ Check the temperature. ■ Caution: If the safety temperature limitation has switched off the small water heater, unplug the mains plug, open the warm water tap and allow approx. 4 litres of water to flow. Then plug the mains plug back in. The appliance is ready again for operation. Limitation of the water temperature The temperature of the water leaving the tap for the small wa- ter heater can be mechanically set to stage “I” (approx. 38 °C) or stage “e” (approx. 60 °C) (see “Operation”, page 14). Conserving energy ■ Set the rotary selector to “e” to conserve energy. ■ Hand over the installation and operating instructions to the user and explain how the appliance operates.13

Operating instructions ■ Before using the appliance, please read the instruc-tions carefully and observe them! ■ Important: The appliance may never be exposed to frost! Risk of electric shock!If a fault occurs, immediately disconnect the plug from the power supply!Immediately shut off the cold water supply to the appliance should it leak.Please read and observe the detailed safety instructions at the start of these instructions! VI. Operation The small water heater heats and stores drinking water up to approx. 85 °C. Setting the water temperature ■ The required outlet temperature from 35 °C to 85 °C can be set with the rotary selector switch. or: ■ Set the required fixed outlet temperature (A): ❄ Frost protectionI Approx. 38 °C (soft lock-in)e Conserve energy approx. 60 °C (soft lock-in)III Hot water approx. 85 °CThe pilot lamp lights up during heat up.Water drips out of the tap with oversink appliances.The appliance with be covered more quickly with limescale at higher temperatures. Tip: Set the rotary selector switch to “e” to operate the appli- ance economically and to reduce the effects of limescale.Note: If the appliance has not been used for an extended period, e. g. during a holiday, allow the water to briefly heat up to stage “III”. Limitation of the water temperature Limit the outlet temperature to avoid scalding with hot water: ■ Set the rotary selector switch to “●“. ■ Open the cover of the rotary selector switch. ■ Select between “I” = approx. 38 °C (B1) or “e” = approx. 60 °C (B2). ■ Close the cover. Switching off ■ Set the rotary selector switch to “●“ (A). The heating is switched off. Undersink appliances only DO05705, DO05755K, DO3170D5, DO3175D5 and DO05705CH Drip stopThe drip stop function prevents expanding water from drip-ping from the tap during heat up. If water is heated, the gas-ses (air) dissolved in it will be released by the water. Depending on the quantity of gas released – particularly when a higher temperature is selected – it can force residual water from the tap.

Pressure stop The appliance features pressure switch off. The pressure switch off indicates when the tap is clogged by limescale (low or no flow). When water pressure exceeds 0.25 Mpa (2.5 bar) it even detects if the appliance has been incorrectly connected with the water line during initial installation. The pressure switch off automatically shuts off the water inlet and prevents rupturing of the tank.It the pressure stop has tripped, a red pin will appear at the top of the appliance (C1). ■ The fault must be corrected (see chapter “A fault, what to do?”). ■ After the fault has been corrected, the red pin can be pushed back in easily (C2). The water inlet is now free. ■ Please contact customer service if this occurs repeatedly. Important: Do not block the path of the pin (C1) with objects. Cleaning Do not use aggressive or abrasive cleaning detergents!Do not use a steam cleaner. ■ Clean appliance externally with a mild cleaning agent. ■ Clean the dirt and lime scale deposits in the aerator filter. Descaling ■ Descale the outlet pipe with commercially available des- caling agent or vinegar. ■ Please observe the manufacturers warnings when descaling.If the water flows significantly slower when the tap is fully opened, the small water heater and tap should be descaled by a specialist. Otherwise, the pressure stop may trip due to an unpermissible high pressure. Maintenance The following repairs and maintenance may only be carried out by an authorised customer service representative to avoid potential sources of danger. ■ The electrical mains supply and the water supply must be shut off before all work on the appliance. Exchange of the electrical connection cable When the electrical cable is visibly damaged: ■ Switch off the device, unplug the mains plug and contact customer service.

Cleaning the inlet filter When the flow of water is too low and the inlet filter in the tap is descaled: ■ Contact customer service and get the inlet filter (D) cleaned.15

You will save yourself the costs of an unnecessary visit by customer service personnel. ■ The electrical mains supply and the water supply must be shut off before all work on the appliance. Fault Cause Solution Who The appliance does not start (heat), only cold water flows. The fuse in the house electrical installation has tripped/blown. Check the fuse in the house electri- cal installation. Customer The mains plug is not inserted. Insert the plug into the mains socket. Customer The safety temperature limitation has tripped. Unplug the mains plug, open the warm water tap and allow approx. 4 litres of water to flow. Insert the plug into the mains socket. Customer Water flow-rate is too low. The filter in the tap is clogged. Remove the filter and either clean it or descale it. Customer The filter in the cold water regulat- ing valve is clogged. Remove, clean and reinstall the inlet filter. Circulate water through the appliance. If necessary, repeat this procedure until the filter is free of particles. Servicing expert The water outlet or the tap is clogged by limescale. Descale or install a new fitting. Servicing expert The tap drips during heat up regardless of the drip stop. Frequent, momentary dispensing or dispensing with a low water flow. Longer dispensing, increase the flow of warm water. Customer The drip stop function is defective. Exchange the appliance. Servicing expert The pressure stop has tripped, water no longer flows. The appliance has been incorrectly installed on the water connection. Connect the appliance correctly, push in the red pin of the pressure stop. Servicing expert The fitting is clogged by limescale. Descale the tap, push in the red pin of the pressure stop. Customer The warm water connection nozzle is clogged. Clean the warm water connection nozzle and exchange the water con- nection if necessary. Then push in the red pin of the pressure stop. Servicing expert If the fault could not be eliminated, please call customer service.16
