with liquid. After pressurizing, close the fl ush cart supply
valve to isolate the fl ush cart. Move the Flow Controller
valves to Position D.
Loop static pressure will fl uctuate with the seasons and
pressures will be higher in the winter months than during
the cooling season. This fl uctuation is normal and should
be considered when charging the system initially. Unhook
the fl ush 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 fl ushing, pressures should be
suffi cient for all seasons.
NOTICE : It is recommended to run the unit in the heating,
then cooling mode for 15-20 minutes each to ‘temper’ the
fl uid temperature and prepare it for pressurization. This
procedure helps prevent the periodic “fl at” loop condition of
no pressure.
