15 – Solar Boiler™ Copper Tube Connections
The Solar Boiler ™ module is prefilled with heat transfer fluid.
Carefully remove the plugs from the brass fittings and retain.
Replace with the 3/8” compression nuts provided. Turn the
nuts on until finger tight.
Insert the marked copper tube in the fitting located on the pump
until it bottoms. Using two wrenches, one on the fitting body
and one on the nut, tighten the nut one full turn.
