c. Feed at the lowest point in the system and connect the return line from all panels to the
highest point in the system.
d. All piping should be sloped continuously downward, towards the existing pump and fi lter.
If there are any low points or traps in the piping, drain plugs should be installed to ensure
complete drainage if the installation is an area subject to freezing conditions.
e. For multiple level, or split arrays, ensure that all return piping rises to a common high
point. Use abank kit (K15BKB) for multiple rows and a split kit (K15SPLB) for roof obstruc-
tions (see the part list of the pool systems in para 5).

8.8 Layout of the Solar Panel Array
a. Determine the exact location of the array, based on the required array confi guration, the
existence of roof obstructions, proper feed and return pipe runs, shading of the panels and
any other specifi c factors that may aff ect the location of the array.
b. Utilizing a chalk line or string, make a horizontal line across as a reference for where the top
header of the panels will be located. Allow suffi
cient room between the headers and the
roof line for pipe runs. Care must be taken to make the horizontal line truly horizontal. For
maximum protection against freezing, slope the entire array toward the feed pipe. The slope
should be 1” per 10’-0” (25 mm per 3 meters).
