THERMAL EXPANSION VALVE (TXV) ADJUSTMENT
Subcool Adjustment
(Refer Subcool Adjustment to Refrigerant Charging Section).
REFRIGERANT CHARGING
Allow the systems to stabilize for 20 minutes before adjusting the thermal expansion valve (TXV) in order to
ensure correct subcooling and superheat conditions. Turn Superheat Adjustment spindle 1/4 turn at a time,
stabilizing the systems in between adjustment, check condition, adjust again if necessary until correct subcool
and superheat conditions are attained.
