COMMISSIONING

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.

Open the gas isolation valve fully.

Check the gas pipe work for leaks.

Open the isolation valve in the pipe work between the outlet of the heat exchanger and the solar pump,

located behind the lower front cover of the solar storage tank (refer to step 4 of “Commissioning the

Solar Circuit” on page 49).

Plug in the storage tank and gas booster at the power outlets.

Commission the solar circuit (refer to “Solar Circuit” on page 47).

Switch on the electrical supply at the power outlets to the storage tank and gas booster.

The power outlets must be switched on for the solar controls to operate and solar gain to be achieved

and for the gas booster to operate and have its frost protection activated.

Open a hot tap.

The gas booster will operate automatically.

Check to ensure the flow from each connected hot tap is sufficient to operate the gas booster.

The minimum operating flow rate is 2.0 litres per minute.

Check the gas inlet and burner gas pressure of the gas booster (refer to “Gas Inlet Pressure” on

page 59 and “Burner Gas Pressure” on page 59).

Check and if required adjust the preset outlet temperature or thermostat setting of the in-series booster.

Refer to “Preset Outlet Temperature Setting” on page 59.

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.
