WARNING
▪ Units which have been set-up and installed incorrectly
can be a health and safety risk endangering human life
and may not operate properly.
▪ Installation commissioning may only be carried out by
authorised and trained heating technicians following
the provided installation and maintenance manual.
▪ Only original replacement parts may be used.
CAUTION
A hot water storage tank commissioned improperly can
lead to property damage.
▪ Observe the regulations in VDI 2035 in order to avoid
corrosion and deposits.
▪ If the filling and top-up water has a high degree of
hardness, measures must be taken to stabilise this
hardness or soften the water.
▪ Set the pressure reducer on the cold water connection
to a maximum of 6bar.
CAUTION
If the electric immersion heater is started with the storage
tank empty or not completely full, it can lead to a reduction
in performance of the electric heating (tripping of the safety
temperature limiter).
▪ Operate the electric immersion heater only with the
storage tank completely full.
Incorrect start-up makes the manufacturer's guarantee for the unit
void. If you have questions, please contact our Technical Customer
Service.
▪ Check all the points on the enclosed checklist. Make a record of
the test results and sign it, together with the operator.
▪ If an electric immersion heater is fitted, set the desired storage
tank water temperature.
