AUXILIARY PUMP
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 with the solar storage tank will
not circulate closed circuit fluid through heights greater than 9 m and solar gain
will not be achieved.
For heights greater than 9 m, an auxiliary pump (kit PN 299914) must be
installed above and within 1 m of the solar storage tank. The installation of an
auxiliary pump will enable a maximum height of 18 m to be achieved. The
auxiliary pump is the same model pump as supplied with the solar storage tank.
Note: The installation of an auxiliary pump does not allow for an increase in
total pipe length of the system. The maximum pipe lengths must be observed
(refer to
“Pipe Lengths” on page 33).
