INSTALLATION – SOLAR CONTROL UNIT
The solar control unit is designed to be mounted on the side of the solar storage tank, with its location above
and offset from the solar cold water outlet. The solar control unit, supplied with a 1.8 metre power cord,
requires a 240 V 50 Hz general purpose outlet (GPO) located within 1.2 metres of its installation. The GPO
must have a continuous power supply originating from a circuit other than the water heater circuit. The GPO
is required to be weatherproof if installed outdoors (refer to “Connections – Electrical” on page 38).

Notes:
Care must be taken when mounting the solar control unit to the side of the solar storage tank. Damage
to the cylinder as a result of mounting the solar control unit to the jacket will void the warranty (refer to
“Saddling - Pipe Work” on page 25).
Use thread sealing tape or an approved thread sealant on all fittings.
