Step 2. Install the reflecting components


Use bolts sort 3

Step 3. Install the tanks into their supports


Step 4. Position of the system

Be sure that all the bolts are tightened and the system is totally rigid. Now you can orient the system. The best direction is south. Avoid shadows on the system.

The system requires a solid base, because the system weight is 170 Kg when it’s full of water. Be sure that the system is horizontal. Fix the 4 bases of the system

Step 5. Collecting tubes installation

Take a tube out of the box carefully

Take out the tube approx 20 cm. Apply the liquid concentrated soap on the top of the tube (10 cm approx) and into the white hole into the tank


Insert carefully the tube into the hole of the tank and turn slowly in the watch direction, until the tube gets inside, approx 5 cm and introduce it turning into watch opposite direction until it gets strongly fixed into its base.

Move the black component to seal the tube with the tank

Put some Teflon at the tube where the hot water goes out (downside of the tank) and install the spherical key

Introduce water into the tank to check if it doesn’t escape. Then fill it until ¾ of the total.

If the system is empty and the sun warms it for more than 30 minutes, don’t fill it because the cold water could break the tubes because of the drastic temperature change. Wait until night to fill it.
