General
Pipe installation must be carried out in accordance with
current standards and directives. F1355 can operate
with a return temperature of up to 58 °C and an outgoing
temperature of 65 °C.
F1355 is not equipped with internal shut off valves;
these must be installed to facilitate any future servicing.
NOTE
The pipe installations must be flushed before
F1355 is connected, so that any contaminants
do not damage the components parts.
NOTE
Do not solder directly on the pipes in F1355,
because of internal sensors.
Compression ring coupling alternatively pres-
sure connection should be used.
NOTE
The heating system's pipes must be earthed
to prevent a potential difference between them
and the building's protective earth.
