Operation Appliance description 3. Appliance description 5. This electronically controlled instantaneous water heater with automatic output matching keeps the outlet temperature constant. This occurs regardless of the inlet temperature up to the output limit. The DHW outlet temperature can be freely selected. The bare wire heating system is suitable for hard and soft water areas; it has low susceptibility to scale build-up. The heating system ensures quick and efficient DHW availability. 4.
Installation Safety 7. Safety 7.1 General safety instructions All required steps to complete commissioning must be carried out by a heating contractor. During this process, these installation instructions must be observed. 7.3 7.3.1 Cold water line Permissible materials: Galvanised steel pipe, stainless steel pipe, copper pipe or plastic pipe. 7.3.2 DHW line Permissible materials: Stainless steel pipe, copper pipe or plastic pipe.
Installation Appliance description 8. Appliance description CAUTION Burns If operating with preheated water, the set temperature limit and anti-scalding protection may be ineffective. ff In this case, restrict the temperature at the upstream central thermostatic valve; see chapter “Accessories”. The bare wire heating system is suitable for hard and soft water areas. The heater has low susceptibility to scale build-up. The appliance is suitable for heating cold water or for reheating preheated water.
Pipe set, offset installation 9.1.3 Appliance with changeover connected load This pipe set with pipe bends is required if you want to have the appliance vertically offset against the water connection by approx. 90 mm downwards. The appliance DHB-E 18/21/24 SLi is set to 21 kW when delivered.
