RUNNING FEED AND RETURN LINES TO GROUND LEVEL
To run feed and return lines to ground level:
1.
Connect the appropriate sized 90° elbow to the return line stub, facing down towards the
bottom header.
2.
Repeat the process for the feed line header stub, again with the elbow facing down, away
from the bank.
Tip:
During the pipelines installation, place a rag on the roof, under the joint, to avoid dripping
cement or damage to the mounting surface with a hot welding tool.
3.
Determine the position on the edge of the roof that the feed and return pipes will pass
over. If possible this should be perpendicular to the exact points where they will fasten into
the existing system (or into pipes coming from another location). (See page 33).
4.
Measure the distance from the return elbow down to the spot that you want to go, across
the roof, to the point established above.
Be sure to include the overlap of the socket into
the elbow in your measurement.
Cut a piece of pipe to this length. Repeat this process for
the feed line.
Tip:
If you are not experienced at cutting and fitting pipes, it is a good idea to assemble all pipes and
fittings before cementing or welding them, just in case there is an error.

.
Measure across the roof from these pipes to the points established in step 3. Cut the pipes
to these lengths, debur the ends, and assemble the corners with 90° elbows.
6.
Continue this process around the edge of the roof and down to the existing plumbing,
keeping pipes as short, straight and close to the building as possible.
7.
Once you are satisfied with the plumbing structure, go back and cement/weld all joints
together.
8.
Secure long pipe runs with clamps, one size larger than the pipe diameter, using stainless
steel lag bolts and silicone/polyurethane caulk.
9.
Secure vertical pipe runs on the side of buildings with clamps
the same size
as the pipe
diameter, using screws and anchors as needed.
Important:
All four corners of each bank of panels must be securely fastened to the roof, while
enabling thermal expansion & contraction of the panels.
Important:
All plumbing must be supported with clamps or pipe straps.
