The collectors may be damaged if the solar heating
system is not filled with heat transfer medium
immediately after installation. Therefore protect the
collectors against insolation by covering them up.
Refer to page 41 for information on venting the
solar heating system.
Installing the General Connection Set and Collector Temperature Sensor
Hydronic Connections
1. Insert the plugs
qZ
until they bottom out, and secure
with profile clips
qE
.
2. Insert the supply and return connection pipes
qT
until
they bottom out and secure them with pipe clips

.
3. Fit the 90° elbow
qU
onto the return connector at the
bottom of the collector.
4. Fit the tee
qO
onto the supply connector at the top of
the
collector.

and secure with strain relief fitting
wQ
.
8. Insert the 4” long, 3” Ø to 22 mm Ø adaptor
qI
into
the compression fittings of elbow
