- Page 2 Sunpower products This is the common-sense warning that we have to include. NOTE In order to guarantee that your safety, please note the following security item, in order to avoid causes the hot water system's damage Before using the hot water, please test the water, in the water bowl.
- Page 3 Product outline and how the Sunpower system works. The collectors are generally installed on the roof, and the water tank on the ground. Sunlight is collected by the evacuated tubes, and converted to heat. This in turn heats a “copper heat pipe “inside the evacuated tube. There is a copper pipette at the top of the tube, which has your tank water circulated around it.
- Page 4 Sunpower systems have a 3.6 Kw electric heating element in the tank. These guarantee all weather hot water availability. They are also able to couple to Natural gas and L P G heaters, as back up heating, instead of using the electrical element.

- Page 18 collectors have simple ½ inch compression olive / nut for the solar flow, and return. Same as the hot water outlet fitting. The system has been designed so all fittings to the tank are on the L H S from the front. It can take a minimum of 150 mm extra width if required, with all the copper pipes / sensor being able to be joined inside this area.
