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 28).

AUXILIARY PUMP
– PLUMBING CONNECTIONS
The auxiliary pump is to be installed:
on the solar cold pipe from the solar storage tank to the solar collectors.
Refer to the label on top of the storage tank to identify the solar cold pipe. The solar cold pipe
connection is located toward the outer edge of the top of the solar storage tank.
within 1 m of the top of the solar storage tank.
with the inlet and outlet in a vertical orientation.
Note: The arrows on the rear face of the pump indicate the direction of flow and should be pointing
upwards when the pump is in the installed position.
with the mounting bracket securely fixed to a structure, such as a wall, with suitable screws or anchors.
wired to the control board and earth connector strip (refer to
“Auxiliary Pump – Electrical Connection”
on
page 42).
with the speed setting set on 3.
This speed setting must not be adjusted. The solar control unit automatically controls and adjusts the
speed of the pump to maximise solar contribution. Manual adjustment of the speed dial setting may
result in the system not operating correctly or efficiently.
enclosed within the mounting cover provided in the kit to protect it from rain as the pump is not
weatherproof.
The mounting cover is to be secured to the mounting bracket with the screws provided.
with the insulation on the solar cold pipe fitted up to the connections of the auxiliary pump, as very high
temperature closed circuit fluid can flow from the solar collectors to the solar storage tank under certain
conditions.
Refer to the installation diagram on page 41.
