• Connect collector flow and return
pipes to the collectors.
• Ensure that you connect the solar
flow (cold) and solar return (hot)
pipes to the correct connections:
– the solar flow (cold) pipe connects
to the
bottom
of the collectors
– the solar return (hot) pipe connects
to the
top
of the collectors,
diagonally opposite to the solar
cold pipe connection.
• We suggest when you install pipes
through roof, that you consider
colour coding the pipe ends to show
flow and return.
Critical: During connection,
the header pipe can move in
the collectors. It is critical that
the header pipe is centred to
provide about 40mm of tube
on both sides of the collector.
