Electrical Connection for Electric AES Systems

4.13.1
The electric element is only connected in models using an electric AES system. No connection
is made to the electric element for gas AES systems.
The electrical booster requires a 220 – 250 volt single phase AC power supply with a capacity
suitable for the kilowatt rating of the element selected for the application. eg. a 2.4 kW element
requires a 10 amp supply capacity.
The power supply must be protected by an individual fuse or circuit breaker rated to suit the
booster size. The supply to the solar water heater can be operated directly from the switchboard
or via a remotely mounted switch or time clock as requested by the customer.
Final electrical connection at the solar water heater tank must be made via an electrical
disconnection device (eg isolator) and connected at the tank as follows: The earth wire is
connected to the earth stud marked with an earth symbol, the active wire connected to the
thermostat terminal marked (L) and the neutral wire is connected to the thermostat terminal
marked (N).
Do not turn on the power supply until the solar water heater has been filled with water
and pressurised. There is a risk of damage to the system if the installation sequence is
not followed.
Using a bicycle pump or similar connected to the jacket relief valve,
as shown to the right, pressurise the system to 120 kPa.
Check all fittings for signs of leakage and tighten if required.
Check over a 10 minute period that the pressure on the test gauge
remains unchanged.
Once it is seen that the circuit is free from leakage release the
pressure in the system through the pressure test block valve fitting
then unscrew the pressure test block from the tank socket.
Refit the 100 kPa jacket relief valve into the tank socket from which
the pressure test block was removed.
The system is now operational and the covers can be removed from
the collectors.
