2. Keep panels as close to the pool equipment area as possible.

3. Always utilize space efficiently so that additional panels may be added at a later date.

4. Keep pipe runs vertically and horizontally to conform with panel array and roof lines. This gives the system. that professional look.

5. Make sure that distance between collectors or collectors and pipe or collectors and roof lInes are adequate for installation and servicing.

6. For freeze protection:

1. Install a vacuum breaker at the highest point or on feed pipe at collectors.
2. Install feed line below collector array.
3. For system that does not facilitate gravity drainage of panels (where solar plumbing crosses the ridge of the roof, or where panels are located below pool water level), provide a hose bib at the lowest point in collector array for manual draining.
