Title: How should the vacuum gauge and vacuum pump be connected to a four-port manifold? Post by: qpitt19777 on Mar 16, 2018 How should the vacuum gauge and vacuum pump be connected to a four-port manifold?
A) The vacuum gauge is connected to the 1/4-in center port, and the vacuum pump is connected to the 3/8-in center pump. B) The vacuum gauge is connected to the discharge service valve, and the vacuum pump is connected to the evaporator coil. C) The vacuum gauge is connected to the 3/8-in center port, and the vacuum pump is connected to the 1/4-in center pump. D) The vacuum gauge is connected to the evaporator coil, and the vacuum pump is connected to the discharge service valve. Q. 2 The rotor turns because of: A) The induced cyclonic effects created by the proximity of the rotor to the stator. B) The repulsion and attraction between the poles of the rotor and stator. C) The directional spin of the electrons in the stator windings. D) Directional spin of the electrons in the rotor winding. Q. 3 The proper order for repairing a system after identifying a leak in a brazed joint on the discharge line is to: A) Recover the refrigerant, repair the leak, leak test the system, evacuate the system, charge the system with refrigerant. B) Recover the refrigerant, leak test the system, repair the leak, evacuate the system, charge the system with refrigerant. C) Charge the system with refrigerant, repair the leak, recover the refrigerant, leak test the system, evacuate the system. D) Leak test the system, repair the leak, recover the refrigerant, evacuate the system, charge the system with refrigerant.
