Remove this cap gently using a screwdriver, ensuring you do not damage any surrounding components. Before making any adjustments, take a reading of the current superheat setting using a superheat gauge.The TXV also needs a proper pressure drop (about 100 PSI); without that pressure drop, the TXV can’t do its job properly. When the suction pressure is low, the technician should take the subcooling and superheat inside and outside. The goal is to look for the temperature differences between the inside and outside measurements.INSTALLATION OF TXV 1. Disassemble flowrater body and remove piston using a small wire or pick. If piston is not removed, expansion valve will not operate properly. 2. Remove the TXV from box and note the location of the inlet side (threaded male port) and the outlet side (female swivel nut port). 3.
