1.
Set the Solar controller to the “ON” position on the slider
switch (refer to Frame 45), the solar pump station will now
circulate the heat transfer fluid around the system. Circulate
until all the air is removed from the system.
2.
Once all the air has been removed from the system, turn the
solar controller to the “OFF” position (refer to Frame 45) and
using the fill and drain valve, slowly drain the heat transfer
fluid until the system pressure reduces to 1 bar.
NOTE. DO NOT USE THE SAFETY ASSEMBLY PRESSURE
