9. Check list for installer
Before leaving from the installation, make sure that:
1. Cold and hot insulated pipes of closed loop system have a continuous ascending slope to the tank. Small
partitions of the piping are allowed to be horizontal, but never descending to the tank. This will allow the
air bubbles to move towards the tank, in the internal expansion tank and would not obstruct recirculation.
2. The closed loop system is operating properly. This can be identified, after one hour of sun shine by
touching the hand on the hot inlet of tank (from top of collector) and at the same time on the cold outlet
(to bottom of collector). There must be a significant temperature difference which means that the natural
recirculation is functioning.
3. There is no leakage at the closed loop or open loop circuit.
4. All bolts and nuts of the support system have been tightened very well and that the fixing on roof is made
properly to withstand strong winds.
5. Cold supply and hot return piping are properly installed and secured so that the wind will not move them.
They should be properly insulated with a certified insulation material of minimum thickness 9mm and
maximum thermal conductivity of 0.037 W/m°K, and well finished in order to be resistant against rain and
moisture.
6. The (optional) electric heater is functioning properly and the thermostat is set maximum at 55
