| Concerning the proper installation of the sensing bulb of a thermal expansion valve that is attached to the evaporator tail coil on a horizontal run, what statement is true? |
| A) the bulb should be attached so that the pinched off tubing should be oriented down and the capillary tube running to the valve diaghragm should be oriented up |
| B) the bulb should be attached so that the pinched off tubing should be oriented up and the capillary tube running to the valve diaghragm should be oriented down |
| C) the bulb should be attached so that the pinched off tubing should be oriented to one side and the capillary tube running to the valve diaghragm should be oriented to the opposite side |
| D) the bulb should be attached with no regard to the orientation of the pinched off tubing or the capillary tube running to the valve diaphragm |
