Requirements
Danger!
Risk of scalding and/or risk of material
damage due to incorrect installation lead-
ing to escaping water.
Stresses in connection cables can cause
leaks.
▶
Install the connection cables so that they
are free from mechanical stress.
Caution.
Risk of material damage due to heat trans-
fer during soldering.
▶
Only solder connectors if the connectors
are not yet screwed to the service valves.
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.
Caution.
Risk of material damage caused by
residues in the pipelines.
Welding remnants, sealing residues, dirt or
other residues in the pipelines may damage
the product.
▶
Flush the heating installation thoroughly
before installing the product.
Caution.
Risk of material damage caused by
changes to the connected pipes.
▶
Only bend connection pipes if they have
not yet been connected to the product.
▶
Install an expansion relief valve on-site.
▶
A discharge pipe with inlet funnel and siphon must be
routed on-site from the discharge line of the expansion
relief valve to a suitable drain in the installation room.
The drain must be visible.
▶
Install a purging device at the highest point in the heating
installation.
▶
Install a filling/draining device in the heating installation.
