Start-up
WARNING!
A ROTEX HPSU compact that is installed or started incorrectly may not operate properly and is dangerous for
the health and safety of individuals.
• The ROTEX HPSU compact may only be started up by authorised and trained heating experts.
CAUTION!
A ROTEX HPSU compact not put into operation properly can lead to damage to property and the environment.
• Observe the regulations in VDI 2035 in order to avoid corrosion and deposits.
• Measures for desalination, softening or hardness stabilization are necessary, if the filling and top-up water
have a high total hardness (>3 mmol/l - sum of the calcium and magnesium concentrations, calculated as
calcium carbonate).
– We recommend Fernox lime and corrosion protective agent
KSK (
15 60 50)
.
• During the plant operation, the water pressure at the manometer (green area) must be checked at regular
intervals. If necessary, readjust by refilling
