Grounding of water piping
V Place a grounding strap on both the supply and return
piping to the tank. (Suitable location).
V Connect both grounding lines (AWG9) with a suitably
heavy line to the main ground of the electrical system.
Piping will receive an automatic air vent during
roof installation (accessory)
V Route the piping with a steady slope down from the air
vent. Install an air vent where necessary at every air
high point in the piping system. (Temperature range up
to 302 °F/ 150 °C).
Warning: Potential system damage due to
very high temperatures and pressures!
V Use pressure and temperature resistant
piping connections.
V Use not any galvanized piping, connec-
tions and graphite or plastic gasket mate-
rials or PEX or plastic piping or
connections of any such type.
V When soldering piping connections, make
sure to use high temperature rated lead
free solder.
(Melt temperature > 455 °F/ 235 °C).
For proper, trouble free and efficient opera-
tion of the entire system make sure to proper-
ly vent the system. Directions for proper
system venting can be found in the Installa-
tion Instructions of the KS solar station.
Make sure to have all piping connections
done by a licensed contractor.
