Rinnai Australia - 58 - Solar Split Systems Operating / Installation Manual

PRE SOLAR HEATING CHECKS

Before commencing solar heating of the water in the system ensure the following actions have been

completed:

Solar Collectors

1. Are the solar collectors installed with the correct slope and orientation to the sun?

2. Is the installation finished neatly with the roof made good, all tiles and flashings in place?

3. Are the bolts tight on the roof framework?

4. Are all solar collector straps fitted and correctly anchored to the roof structure?

5. If leak testing completed and successful, have any covers been removed from the solar collectors?

6. Has operation of the solar pump been checked?

7. Have the hot and cold sensors and leads been positioned and connected correctly?

Electric Heating Elements

1. In systems with a single heating element only has the thermostat set point been set to at least 60°C

and no greater than 70°C.

2. In systems with both a lower and upper (or booster) element, has the thermostat set point of the lower

element been set to at least 60° and no greater than 70°. Has the upper element been set to 10° less

than the lower element? .

Temperature Limiting Devices

1. Commission any temperature limiting devices in accordance with the instructions supplied by the

manufacturer.

2. Confirm the hot water delivery temperature at a tempered water outlet. Tempered water outlets

should be those supplying areas primarily used for the purposes of personal hygiene such as

bathrooms. The hot water delivery temperature should not exceed 50°C or 45°C as detailed in the

section ‘Hot water delivery temperature’.

SOLAR HEATING

1. Remove any cardboard or tarp covers that may have been placed over the solar collectors to prevent

them from heating water during installation and commissioning.

2. Activate electrical power to both the gas booster and solar pump and controller. Solar heating of the

water in the cylinder will now commence when sufficient solar reduction is available.

Auxiliary Energy Supply

1. Connect the electrical element to the power supply (off peak if available).

2. When the system is full of water turn on electrical supply to element.

FINISHING THE INSTALLATION

After testing is completed explain to the householder the functions and operation of solar water heater

components. Also explain to the householder the importance of carrying out Maintenance as per

separate warranty document.

Leave this Manual with the householder.

Remind the householder to complete the 'Warranty Certificate' provided in the separate warranty

document.
