As shown in the diagram (scheme) the water must always run from below upwards, to ensure the absorber (collector) is completely filled with water. So water should be supplied from below to run back down from the highest point. The air supply valve, at the highest point, provides the necessary air supply in case the pump doesn’t function. In this scenario, the tubes would suck together because of the weight of the water waiting to run down. This would create dangerous under-pressure in the absorber. To prevent frost damage in the winter avoid leaving water in the headers. The rubber mat itself is frost-resistant.

The filter pump is normally strong enough to send the water from the swimming pool (pond) and into the absorbers on the roof (Max. 6 metres higher without extra pump), because there is hardly any loss of pressure.

For a general diagram of the framing and the operation of your installation see below:

1) On an inclined surface
Place the collector at the water source and secure it onto the tie-beams under the roofing using the metal butt-strap (but-string) provided. Place another collector on top for the heated water running down. You can also use a synthetic ribbon every metre to fasten the absorber onto the roof. There are several products on the market for gluing EPDM onto the roof surface. Just clean the roof surface thoroughly before using the glue.

2) On a flat roof (surface):
Here you can also use an appropriate glue every metre, or a synthetic ribbon to fix the absorbers onto the roofing. The ribbons are then fastened at each side with a ballast.

3) On grass/sand/lawn
You can walk on the absorbers, but bear in mind that the grass underneath will scorch.
