How to use ? - Solar hot water panel
Step 3
Bend the copper tube to form a circuit as shown.
Do not create too pronounced angles as it could "fold" the tube.
The use of special pliers avoids this risk and gives a more regular shape to the circuit. Place the copper circuit in the center of the panel by passing first (from inside) the two tube ends through the holes.
Step 4
Attach the circuit against the panel by tying it with some metal wires. Pass the wire through the layer of polyurethane and tie it the other side. Small pieces of cardboard can avoid the wire from cutting through the foam.
With some universal glue, seal the surrounding of the tubes inside de panel and let it dry.
Do the same thing where the tubes come out on the other side. Pass the cap on the tubes and push against the glue. Fill the cap with about 1 cm of glue. Let it dry.
