NOTES:
1) Unions and valves must be installed so that acid flushing
of the heat exchanger is possible.
2) Make sure there is not a check valve in the diptube of the
tank.
3) Route thermistor wires to NSKW. Remove yellow
thermistor wires on TB 3 and 4 from control box and
connect thermistor wires from geothermal storage tank.
Set the pump sampling (PS) in the set up of the control
board to continuously (C) sampling (reference Note 5 in
