If you were checking an air conditioning system for proper thermostatic valve installation, the sensing
bulb should be:
a. firmly clamped to the suction manifold of the coil.
b. wrapped with insulation, right along with the suction line.
c. mounted on a section of the suction line where it will sense liquid refrigerant.
d. mounted on a section of the suction line where it will sense gas refrigerant.
e. located just upstream from the place where the external equalizer line penetrates the suction line.
f. located just downstream from the
place where the external equalizer line penetrates the suction line.
