Calculation of the operating point

In connection with a Helios hot water heating element WHR.., the following guide values for the differential pressure
setpoint are approximated:
Type Water Line cross-
section
WHR volume
250 470 l/h
315 810 l/h
355 1080 l/h
400 1060 l/h
2/40/20 610 l/h
4/40/20 980 l/h
2/50/25-30 1050 l/h
* The pressure loss in the piping depends on the pipe length, pipe diameter and the water flow rate!

Maintenance and servicing

The safety instructions in chapter 1.3 must be observed!
– It must be ensured that the assembly has been disconnected from the mains power before any work!
– In principle, the assemblies are maintenance-free, user maintenance is not envisaged.
However, any necessary maintenance work must be carried out by authorised, qualified personnel!
After maintenance and servicing work, the following must be checked:
• fittings, water connections and pipes are tightly fitted
4.2

Spare parts

Only Helios original spare parts must be used. All repairs must only be carried out by authorised, qualified personnel/
companies.
4.3

Decommissioning and disposal

Dispose of the components used according to the locally applicable regulations and laws.
