Installation - Solar
Connection To Solar Primary Circuit
The lower (solar) coil of the S
OLAR
cylinder must be
connected to a fully pumped solar primary circuit. The
connections are suitable for 22mm copper pipe direct
to the compression fittings provided. The connections
are also threaded 3/4” BSP male parallel should BSP
be required.
The solar primary circuit should have its own dedicated
circulating pump and safety controls which must be
installed as per the manufacturer’s instructions.
Control of Solar Primary Circuit
Temperature control of the S
OLAR
cylinder must be
carried out using a suitable proprietory solar controller/
programmer. The cylinder temperature sensing probe
(supplied with the solar controller) should be fully
inserted with the thermal cut-out probe into the pocket
provided on the SOLAR
cylinder.The cable must
be secured using the cable clamps on the controls
housing.
Connection to the solar controller should be in
accordance with the manufacturers instructions.
The solar controller should be programmed to give a
cylinder temperature of approximately 60°C (maximum
70°C).

SOLAR CONTROLLER
The solar controller and solar primary circulation
pump must be wired via the over-temperature cut-out
mounted in the lower solar controls housing. This will
ensure that the heat input to the solar coil is interrupted
in the event of the cylinder over-heating (see Fig. 07
below). There must also be suitable check (non-return)
valves installed in the solar primary flow and return to
prevent the possibility of any thermo-syphoning if the
solar circulation is stopped.
