Auxiliary Pump - Solar Circuit
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 (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. Note: The installation of an auxiliary
pump does not allow for an increase in total pipe length of the system. The maximum pipe
lengths shown in the table on page 12 must still be observed.
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.
The auxiliary pump speed setting must be set on 3. The solar control unit automatically
controls and adjusts the speed of the pump to maximise solar contribution. Manual
adjustment of the speed dial setting on a setting other than 3 may result in the system not
operating correctly or efficiently. Note: If an auxiliary pump is utilised it will switch on with
pump 1, run for 3 minutes to establish circulation then switch off. After this period pump 1
maintains circulation.
The two wire plug from the auxiliary pump connects to the terminals marked “PUMP 2” on
the control board (refer to wiring diagrams on pages 5 & 6) and the earth wire spade
connector from the auxiliary pump connects to a terminal on the earth connector strip
located on the bracket adjacent to the control board. For information on installing an
auxiliary pump refer to ‘Installation Instructions – Auxiliary Pump Kit Solar Drain Back
Water Heater’.
