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 See "HOT
WATER DELIVERY TEMPERATURE" on page 18.
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 radiation 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 Operating/Installation Manual with the householder. Warranty documentation is provided in a
separate warranty manual.
