FILLING THE DHW TANK
- Open and leave open the cock (5) for the domestic
cold water inlet (CWI).

cold water from the mains supply. When water starts
coming out of the hot water tap, leave it run until you
obtain an even flow then close the tap. The DHW tank
is now full.
FLUSHING THE SOLAR COLLECTOR CIRCUIT
Carefully check all connections and unions for leaks before
filling the system with the water and glycol mix. Use the
following procedure to test for water tightness. The same
procedure can also be used to flush out the circuit to remove
any residues.

a cold water tap using a length of hose pipe.
- Connect the union (2) on the storage cylinder to a
drain.
