Danger!
Risk of scalding and/or damage due to
incorrect installation leading to escaping
water.
Mechanical stresses in the connection pipes
may lead to leaks.
▶
Install the connection pipes such that they
are free from mechanical stress.
Caution.
Risk of material damage caused by corro-
sion
Due to non-diffusion-tight plastic pipes in the
heating installation, air gets into the heating
water. Air in the heating water causes corro-
sion in the heat generator circuit and in the
product.
▶
If you use non-diffusion-tight plastic pipes
in the heating installation, ensure that no
air gets into the heat generator circuit.
