5 – Copper Tube at Solar Collectors
The copper tube roof penetration is made adjacent
to the “A” collector for the SB64-9PV system and
the “B” collector for a SB32-9PV system.
Make a roof penetration at a position 8" - 10" hori-
zontally away from the “A”, (“B”) collector bottom
ports. A 3/8” hole for each tube and the wire is
sufficient.
Pass about 2 feet of Copper tube through the roof
penetration from below. Clamp the copper tube to
the truss. Do not crimp the copper tube.
Seal the roof penetration with silicon sealant.
If the copper tube has been installed on the outside
of the house, a roof penetration is not necessary.
Simply bend the tubing bundle around the soffit
and up to the solar collectors
Connect the 3/8" copper tube to the "IN" (blue) port using a 5/8" and 11/16”
wrench. Be sure to hold the bulkhead union from moving during this process.
Connect the other 3/8" copper tube to the "OUT" (red) port.

Bulkhead Union
3/8” Compression
Nut
IMPORTANT: The 11/16” wrench is required to pre-
vent the bulkhead union from rotating while turning
the nut with the 5/8” wrench.
As of January 2010, S Series collectors are
equipped with Bulkhead Union locking plates. This
eliminates the need for an 11/16” wrench.
