STEP 6: CONNECT THE 6' HOSE TO ICM
Using the ½" nipple,
couple the 3' long flex hose
provided in the adapter
kit to the 3' long flex hose
provided in the solar water
heating system kit, to make
a 6' finished hose. Attach
the 6' flexible hose to the
nipple. Attach the other
end of the flexible hose
to the threaded fitting on
top of the ICM by carefully
forming hose so as to not
apply a side load to the fitting. Note: Flexible hose
does not require thread sealant.
