TO FILL AND TURN ON THE WATER HEATER
The power supply to the water heater must not be switched on until the solar storage tank is filled with
water.
To fill the solar storage tank with water and turn on the water heater:
•
Open all of the hot water taps in the house (don't forget the shower).
•
Open the cold water isolation valve fully on the cold water line to the water heater.
Air will be forced out of the taps.
•
Close each tap as water flows freely from it.
•
Check the pipe work for leaks.
•
Inspect for leaks at the temperature pressure relief valve connection to the water heater.
If a leak is detected, close the cold water isolation valve fully and relieve pressure from the water heater
by either operating the easing lever on the temperature pressure relief valve or opening a hot tap. Remove
the valve and all of its thread sealant from the threads of the valve. Reapply new thread sealant and refit
the valve. Refer to the procedure in
•
Operate the easing lever on the temperature pressure relief valve to check the smooth operation of the
valve plunger and that water discharges freely from the drain line. It is very important the lever is raised
and lowered gently. The lever should move smoothly and without undue force.
If the lever cannot be moved or is jerky in its movement, then the valve has been damaged and must be
replaced.
•
Open the gas isolation valve fully.
•
Check the gas pipe work for leaks.
•
Plug in the solar storage tank and in-series gas booster at the power outlets.
•
Commission the solar circuit (refer to
•
Switch on the electrical supply to each of the solar storage tank and in-series gas booster at the power
outlets.
The power outlet must be switched on for the solar controls to operate and solar gain to be achieved and
for the in-series gas booster to operate and have its frost protection activated.
•
Open a hot tap.
The in-series gas booster will operate automatically.
•
Check to ensure the flow from each connected hot tap is sufficient to operate the in-series gas booster.
The minimum operating flow rate for all models is 2.0 litres per minute.
•
Check the gas inlet and burner gas pressure of the in-series gas booster (refer to
"Burner Gas Pressure"
page 61 and
•
Check and if required adjust the preset outlet temperature setting of the in-series gas booster.

Explain to the householder or a responsible officer the functions and operation of the solar water heater.
Warning: Upon completion of the installation and commissioning of the water heater, leave this guide with
the householder or a responsible officer. DO NOT leave this guide inside of the cover of the water heater, as
it may interfere with the safe operation of the water heater or ignite when the water heater is turned on.
If it is necessary to turn off the water heater on completion of the installation, such as on a building site or
where the premises is vacant, follow the procedure
