CONNECTIONS – PLUMBING

To connect the solar cold and solar hot pipes to the solar storage tank:
• Remove the compression nut and olive from each
of the solar cold outlet and solar hot inlet fittings at
the top of the solar storage tank. Remove the
rubber washer from each of the unions and
discard.
• Connect the solar cold pipe (flow to the collector) to
the nipple in the solar cold outlet using the
compression nut and olive supplied.
• Connect the solar hot pipe (flow from the collector)
to the nipple in the solar hot inlet using the
compression nut and olive supplied.
AUXILIARY PUMP
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 must be installed. This pump is the same model as contained within the solar storage
tank.
The auxiliary pump (kit PN 299914) is to be installed:
• on the solar cold pipe from the solar storage tank to the solar collectors
• within 1 m of the top of the solar storage tank
• with the inlet and outlet in a vertical orientation
• securely fixed to a structure, such as a wall, with suitable screws or anchors.
• wired to the control board (refer to “Auxiliary Pump” on page 34).
• within a suitable weatherproof enclosure to protect it from rain as the pump is not weatherproof.
The installation of an auxiliary pump will enable a maximum height of 18 m to be achieved.
