Collector Top Connection:
At the collector top connection, connect the supplied 90
o
-
compression fitting. (An extension is supplied with flush
mount kits to make installation easier)
Attach the pressure relief valve unit, then the air vent
(appearance may vary from pictures).
A clean way to install is to put in a 90
o
-compression
union at this point and drill a 1 1/2” hole directly below it
for the roof boot flashing to be installed. Cut the shingle
as needed and slide the roof boot flashing into place.
The copper tubing will be installed into the union and the
hole in the flashing later filled with caulk and insulated.
Tighten, but do not over tighten the connections. Be
sure the line with the pressure relief and other valves
on it are parallel with the roof. The pressure relief
valve should be tightened so it faces down directly
onto the roof, onto the supplied aluminum splash
sheet, for safety. The air vent must face directly up,
with no tilt, for proper operation.
Bottom Connection of Collector:
When the end of the union is flush with the edge of the
collector, alignment in the colle ctor is correct.
If a straight union is installed for shipping purposes, it
will usually be removed and replaced with a 90
o
union.
Use the straight unions for the tank end connections.
Put in the 90o compression union at this point and drill a
1 ½” hole directly below it for the roof boot flashing to be
installed.
Cut the shingle as needed and slide the roof boot flashing
into place. The copper tubing will be installed into the
union and the hole in the flashing later filled with caulk
and insulated.
NOTE: The hole in the side of the collector will be
covered with insulation as a final step. All insulation
over fittings is done last, after the system is
pressurized, to allow for checking for leaks and
tightening the unions as needed.
Paint outside insulation with Latex paint or
cover with aluminum tape to protect it from UV
degradation.
The 50’ roll of ½ OD copper tubing is easily unrolled and
straitened by placing it on the ground and unrolling it as
you lightly step in the unrolled portion.
It is sometimes easiest to feed the pipe down through
the roof boot flashing and into the tank area.
A variety of techniques can be used depending on the
situation such as needing to pull the pipe through an
attic where it may need to come up from the bottom
and be fed through the roof.
To locate the return line hole, place the 90 degree compression union on the
upper tube and snug up. Place the upper return assembly with air vent, pressure
relief valve into the 90. Center absorber in collector and make a mark 1” in
front of the end of the tube. Drill a 1 ½” hole centered on the mark.
Slip the flashing under the
PRELIFTED shingles as shown.
