1 Use The domestic hot water tank serves for heating and storing process water. Above all, solar systems and supplementary heating systems, like gas, oil heaters or solid boilers, are the heat generators that come into consideration. Any other use, or use over and above that described, will be considered not in conformity with intended purpose. The manufacturer rejects all liability for damage from usage not in conformity with intended purpose and the owner/operator alone bears the risk. 2 Safety Instructions and Explanation of Symbols 2.1 Safety instructions The tank may only be installed, commissioned and maintained by qualifi ed technical personnel. This appliance is not intended for use by persons (including children) with limited physical, sensory or mental abilities or with a lack of experience and/or knowledge, unless they are being supervised by a person who is responsible for their safety, or have received instructions from such a person as regards its use. Comply with the instructions, so that troublefree working is ensured. Install only in dry and frost-free rooms. Operate only at ambient temperatures between +2 C and +40 C. The operating pressures given on the type plate may not be exceeded! Touching the tank during operation can result in burns. The installation and operation must be carried out in keeping with the locally applicable regulations and standards or directives. For maintenance, or in case of faults, contact the responsible technical workshop. We reserve the right to make changes owing to technical improvements.. Use 3

6 Installation 6.1 Installation of the tank Electrical heating elements may only be installed by approved electrical technicians. A dry, frost-free room that provides suffi cient space for maintenance work is requried as the installation site. The compact hot water storage tank must be installed so that it is protected from splashing water and may only be run at room temperatures below 40 C. When positioning the tank, it is necessary to ensure that the underlying ground is of suffi cient strength.. The tank should be positioned min. 10 cm away from the wall The connections should be made according to EN 806-1 and DIN 4753/1. To equalise pressure variations or water hammers in the cold water network and to avoid unnecessary wastage of water, we recommend the installation of a suitable expansion vessel with fl ow fi ttings. 7 Comissioning Damage to property Start up the machine only after it has been completely fi lled Check the union nuts for fi rmness. Rinsing the machine. Filling and venting the machine till the system is completely de-aerated. Before commissioning, check whether the water supply has been opened and the tank fi lled. The compact hot water storage tank may not be operated above 95 C. The ideal operating temperature is 50-60 C. With these operating temperatures, you can save energy and avoid the heat-dependent calcifi cation. Electrical heating elements may only be installed by approved electrical technicians. Care must be taken that the electrical heating element is connected in keeping with the circuit diagram and in accordance with the country-specifi c regulations. The specifi cations of the EVU and VDE must also be mandatorily observed. The electrical heating element should be maintained annually and de-calcifi ed if required. Flow noises indicate air trapped in the machine. After commissioning, the function and the air tightness of the entire machine should be checked. 8 Installation We reserve the right to make changes owing to technical improvements.
7.1 Maintenance The cleaning of the tank and the inspection of the plant should be carried out annually. The functional safety of the safety valve should be checked at regular intervals, with an annual maintenance by technical personnel being recommended.. The magnesium anode should fi rst be checked the fi rst time after 2 years, according to DIN 4753, and then every year, and replaced if required. 8 Warranty The manufacturer has a warranty on the supplied product and its components of 5 years from the date of delivery. Unauthorised modifi cations or changes are not permitted for safety reasons and will inevitably lead to the voiding of the warranty for the machine.
