INSTALLATION – SOLAR CONTROL UNIT
SOLAR CONTROLLER KIT
The solar water heater is designed for the solar collectors to be roof mounted
and the solar storage tank to be installed at ground or floor level. This solar
controller kit is designed to be mounted on the side of the solar storage tank
incorporating a raised solar hot water inlet.
The solar control unit governs the operation of the solar water heater. For full
details on the installation of the solar storage tank, the cold water plumbing
supply details and electrical connections to the tank, refer to the Owners Guide
and Installation Instructions supplied with the solar storage tank. The Owners
Guide also contains consumer information on the operation of the solar water
heater system.
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 12).
The solar control unit automatically controls the flow rate through the collector
circuit. This is achieved via the hot and cold sensors and differential controller
programming providing control over the operation of the circulator. There is no
provision for nor is adjustment to the solar control unit required.
Notes:
Care must be taken when mounting the solar control unit to the side of the
solar storage tank. If the cylinder is damaged as a result of mounting the solar
control unit to the jacket, any resultant faults will not be covered by the
manufacturer’s warranty (refer to “Saddling - Pipe Work” on page 11).
All pipe work must be purged and cleared of foreign matter before connection
and before attempting to operate the water heater.
It is important to connect the solar cold and solar hot pipes to the correct
connections at the solar storage tank.
Connect the solar pipes to the solar storage tank using only the fittings
supplied.
All olive compression fittings must use brass or copper olives.
Use approved thread sealant such as Teflon tape on all other threaded joints.
