- Before installing a gauge on the high-pressure side of a system, you should do which of the following? A. Turn on the system. B. Turn off the system. C. Adjust the system to a neutral position. D. Have a cylinder approved by the DOT nearby.arrow_forwardWhich of the following statements about manifold gauge sets is not true? An adapter is required for using R-12 gauges on an R-134a system. A manifold gauge set is used when discharging, charging, and evacuating and for diagnosing trouble in an A/C system. The gauge manifold is designed to control refrigerant flow. When the manifold test set is connected into the system, pressure is registered on both gauges at all times. R-134a service hoses have a black stripe along their length, the low-pressure hose is blue, and the high-pressure hose is red.arrow_forwardAll gauges operate but read lower than normal: Technician A says that the connection to the instrument cluster may be corroded.
