INSTALLATION INSTRUCTIONS
SOL 27 PREMIUM S & W COLLECTORS - 230016 & 230017
Thermal Insulation
All exterior piping also requires UV and moisture protection.
Insulation must be resistant to temperatures up to 356F.
Use the following recommended temperature and UV-
resistant thermal insulation to insulate the external
pipework:
» Polyisocyanurate, PVC cover
» Armafl ex®
» Mineral wool backed by aluminum mesh foil
» Flexible EPDM hose
A rigid aluminum sheath is recommended as protection
for the mineral wool. The EPDM hose can be fi nished with
UV-resistant paint. Where required, protect the thermal
insulation against bird or rodent attack. Insulate all lines of
the solar loop. Apply the thermal insulation after pressure
testing and checking the system for leaks.
Extremely cold climates that experience nighttime winter
temperatures below -30F may need thicker pipe insulation
to prevent pipe freeze-ups or slushing of the antifreeze
mixture.
Minimum Insulation Thickness
Diameter of Pipe Minimum thickness of insulation layer
Less than ¾˝ ¾˝
¾˝ to 1 ¼˝ 1˝
1 ¼˝ to 4˝ Identical to pipe diameter
Greater than 4˝ 4 ˝
Collector Temperature Sensor
The collector sensor is immersed into the outlet pipe of the
collector array (i.e., positioned at the hot side). Secure the
lead to the outside of the insulation (to avoid melting under
high temperature operation) and under a protective cover.
Cover the outlet pipe and the roof outlet with thermal
insulation, which must be tightly sealed and must be
temperature and UV resistant.
