Hydraulics installation
5.1
Carrying out the installation preparations
▶
Install the following components, preferably from the
manufacturer's accessories:
–
An expansion relief valve, a stopcock and a mano-
meter on the heating return
–
A domestic hot water safety assembly and a stopcock
on the cold water supply
–
A stopcock on the heating flow
▶
Check whether the volume of the installed expansion
vessel is sufficient for the heating system. If required, in-
stall an additional expansion vessel, connected as close
to the product as possible, in the heating return.
▶
Install the connection pipes such that they are free from
mechanical stress.
▶
If you are using metallic pipes to connect the pipe to the
outdoor unit, earth the pipes.
▶
Heat-insulate the pipes.
▶
Only solder connectors if the connectors are not yet
screwed to the service valves.
▶
Carefully flush the heating installation before connecting
the product.
▶
Check whether the expansion relief valve's drain pipe-
work opposite the outdoor air remains open, is installed
in a frost-free environment, always runs downwards and
visibly ends in an open drain.
