Page 9: Hydraulic Installation
InstallatIon and InstructIon manual FRESH watER Station Hydraulic installation Install the hydraulic piping according to the instructions in chapters "Installation on buffer tank" and "Wall fastening". Piping Piping between buffer tank and Fresh Water Station ought to be as short as possible. When using different piping materials take care of the installation sequence to avoid electrochemical corrosion Personal and material damage The tap water supply needs to be constructed according to specification (Picture below ). -
Page 10: Installation Of Circulation Unit
Installation of circulation unit Personal and material damage Sufficient expansion and overpressure safety devices must be installed in the circulation circuit A rinsing port needs to be installed in the circulation circuit. Electrical connection of circulation unit Danger to life Manipulation of electrical parts must be conducted by a professional electrician. Deenergize the device before opening it. Local regulations must be observed! Connect the circulation unit according to the desired operating mode. -
Page 11: Operating Modes Of Circulation Unit
InstallatIon and InstructIon manual FRESH watER Station Operating modes of circulation unit Circulation shutdown temperature The circulation will be deactivated when the shutdown temperature is reached. The preset temperature at the temperature dial (A) must be at least 10 K below the set temperature at the Fresh Water Station to avoid non-stop operation of the circulation unit Set the temperature dial to the desired temperature. -
Page 12: Initiation
Initiation Material damages Put fresh Water Station into operation only after completed filling. • Check tightness of swivel nuts.. • Fill device and check for leak-tightness. • Open valves on both buffer and tap water sides slowly to avoid pressure blows. • Connect device to power supply. • De-aeration and rinsing of device: • Open a nearby hot water tapping point and turn thermostatic head to maximum. -
Page 13: No Hot Water
InstallatIon and InstructIon manual FRESH watER Station No hot water Cause Relief Buffer tank not hot enough • Increase temperature in buffer tank Charge pump doesn’t • Check water level in buffer tank (extraction of buffer water for the convey buffer water Fresh Water Station happens at the highest point of the tank) • De-aerate buffer circuit and check system pressure • Check, if all shutoffs (buffer and tap water side) are open. -
