The hot water at the tap can reach a temperature of up to 65 C (PSH 30-50 Si) / 62 C (PSH 75-50 Si). There is a risk of scalding at outlet temperatures in excess of 43 C. Small children should be kept away from the taps. 4.2 Adjustment options 4.2. Temperature adjustment PSH 30-50 Si 26_02_20_0026 Risk of injury The appliance may be used by children aged 8 and up and persons with reduced physical, sensory or mental capabilities or a lack of experience provided that they are supervised or they have been instructed on how to use the appliance safely and have understood the resulting risks. Children must never play with the appliance. Children must never clean the appliance or perform user maintenance unless they are supervised. 2.3 CE designation The CE designation shows that the appliance meets all essential requirements according to the: Electromagnetic Compatibility Directive Low Voltage Directive The type plate is located at the bottom of the appliance. 3. Appliance description The wall mounted DHW cylinder constantly maintains the DHW at the pre-selected temperature. The water is heated by the electrical heating element. The appliance is preset at the factory to 65 C (PSH 30-50 Si)/ 62 C (PSH 75-50 Si). For appliances of type PSH 75-50 Si, The temperature setting should only be made by a contractor. The expansion water that collects as the water is heated up is drained off via the safety valve. The inner cylinder of the DHW cylinder is protected against corrosion by an enamel coating in conjunction with the integral protective magnesium anode. 4. Operation 4. Other relevant documents For operation, also observe the operating instructions of the relevant accessories and any appliance documentation. temperature selector (only for PSH 30-50 Si) By turning the temperature selector, you can select the temperature of the water in the DHW cylinder. Turn it clockwise to raise the temperature, and anti-clockwise to lower the temperature. As soon as the temperature of the water in the DHW cylinder drops below the set value, the heating element automatically switches on. The ON/OFF indicator illuminates until reheating is complete and the set temperature has been reached again. 4.2.2 Temperature adjustment PSH 75-50 Si temperature selector The temperature set at the factory can be changed by a contractor. To do this, the temperature controller inside the appliance 26_02_20_0030 6 PSH Si www.stiebel-eltron.com

Operation Cleaning, care and maintenance must be turned to the required position (position 5 corresponds to approximately 62 C). 4.3 Recommended settings 4.3. Water temperature The water temperature is continuously variable, and can be set subject to your requirements. The setting range extends from approx. 5 C to approx. 65 C (PSH 75-50 Si: 5 C to 62 C). For low water consumption or very hard water, we recommend setting the cylinder to a low temperature, as water above approx. 55 C deposits the limescale contained in it. Have a contractor regularly check the appliance and safety valve. Danger to life through electrocution Maintenance work, such as checking the electrical safety, must only be carried out by a qualified contractor. To safeguard a long service life, we recommend having a contractor inspect the protective magnesium anode installed in the appliance after the first year of service. The contractor should determine further maintenance intervals. Annual maintenance intervals could be necessary in areas with particularly hard water. ENGLISH 4.3.2 Holiday and absence During a prolonged period of absence, such as a holiday, you should set the appliance to frost protection or disconnect it from the power supply, in order to save energy. To do so, observe the details in the frost protection chapter. 4.3.3 Sporadic use For only sporadic use, such as in a weekend home, you should set the appliance to frost protection or disconnect it from the power supply when you are not there. For reasons of hygiene and health, you should heat up the content of the cylinder once to above 60 C before initial usage. 4.3.4 Frost protection In the frost protection setting, the cylinder is protected against frost, but the safety valve and water lines in the apartment or house are not. If the appliance are disconnected from the power supply, the cylinder is not protected against frost. In such cases, if there is a risk of frost, the cylinder must be drained. ffclose the cold water inlet. ffopen a DHW draw-off point. ffopen the drain valve or the drain valve on the safety valve, and fully drain the cylinder. Risk of scalding. Hot water may emerge during draining. 6. What to do if...? Fault Troubleshooting checks No hot water Has the power supply (fuse or MCB) been interrupted? If so, reset the fuse or MCB and wait until the cylinder has heated up again. Notify your contractor if the fuse/mcb blows/trips again after you have reset it. No hot water Is the temperature set high enough? Set the temperature slightly higher. No hot water Is the ON/OFF indicator illuminated? When the ON/ OFF indicator illuminates, the appliance heats the cylinder content. This can be necessary, for example because a large volume of water was previously drawn. Wait until the ON/OFF indicator extinguishes again. No hot water Is the ON/OFF indicator illuminated? If the ON/OFF indicator is not illuminated and all other causes have been checked, this can indicate that the high limit safety cut-out has responded. Notify your local contractor. Too little hot water Is the temperature set correctly? If all other possible sources of the fault have been eliminated, the appliance may have been sized too small. In this connection, also observe the maximum DHW draw-off volume, as specified in the "Specification" chapter. Low DHW outlet volume Are the draw-off points scaled up? Limescale on the draw-off points reduces the output volume. Descale and clean the outlet points. If this does not remedy the fault, inform your local contractor. The safety valve is dripping This is normal during heat-up. If the safety valve continues to drip after heat-up is complete, inform your local contractor. 5. Cleaning, care and maintenance A damp cloth is sufficient for cleaning the casing. Do not use abrasive or corrosive cleaning agents. ffcheck the tap regularly. Remove limescale deposits at the tap outlets using commercially available descaling agents. ffregularly activate the safety valve to prevent it from becoming blocked by limescale deposits. ffcheck the safety valve is functioning correctly by pulling out or turning the rotary selector. When you do so, water will escape from the safety valve The drip water outlet of the safety valve must always remain open to atmosphere, and must never become narrower or blocked. Route the drip water outlet to a drain free from the risk of frost, with a constant slope to ensure the unrestricted flow of the water to the drain. www.stiebel-eltron.com PSH Si 7
