The solar collectors must be the
highest point of the system. The
maximum height of the solar
installation, from the base of the
solar storage tank to the top of the
solar collectors, is 9 m. The pump
supplied will not circulate closed
circuit fluid through heights
greater than 9 m and solar gain
will not be achieved.
For heights greater than 9m, an
auxiliary pump kit (PN 299914)
must be installed. Refer to
‘Auxiliary Pump - Solar Circuit’ on
page 13 for more information. The
installation of an auxiliary pump
will enable a maximum height of
18 m to be achieved.

Notes:
• For each additional 90° bend, reduce the maximum total pipe length by 0.5 metres.
• For each additional metre of pipe length, reduce the number of 90° bends by two.
• One 90° elbow is equal to two 90° bends.
