Flushing the Earth Loop
Loop static pressure will fluctuate with the seasons and
pressures will be higher in the winter months than during
the cooling season. This fluctuation is normal and should
be considered when charging the system initially. Unhook
the flush cart from the Internal Flow Controller. Install Flow
Controller caps to ensure that any condensation/leakage
remains contained within the Flow Controller package.
If the loop pressure is between 50 and 75 psi [345 to 517
kPa] upon completion of flushing, pressures should be
sufficient for all seasons.

NOTICE: It is recommended to run the unit in the cooling,
then heating mode for 15-20 minutes each to 'temper' the
fluid temperature and prepare it for pressurization. This
procedure helps prevent the periodic "flat" loop condition of
no pressure.
