Danger!
Risk of death from electric shock!
A continuous voltage is always present on
the mains connection terminals L and N.
▶
Disconnect the product from the power
mains by de-energising the product using
a partitionb with a contact opening of at
least 3 mm (e.g. fuses or power switches).
Caution.
Risk of damage to the electrical lines as a
result of high temperatures.
The electrical lines may be damaged by the
high temperatures from the solar fluid that
flows through the copper pipes.
▶
Make sure that the electrical lines are
not positioned directly next to the pipes
through which the solar fluid flows.
