Attach to the hoses and gauge set to the high and low side ports of your AC system.

How to put gauges on ac unit. Connect the high side. The low-pressure side goes to the blue port on the gauge. After it is off hook up the refrigerant gauges to the valve connections.

They should be the same because the high and low side pressure equalize once the compressor shuts off. With both low- and high-side valves still closed start the vehicle and turn on the ac to max. Hook your manifold gauges onto something so they are stationary this is the key for an accurate weigh in.

Open the gauges to get the PSI readings on your unit. Be sure the refrigerant container stands upright for the duration. Connect the red gauge to the high side service port on the AC unit.

Then put on some gloves and safety glasses to protect yourself from the Freon and turn off your AC. Connect your charging hose to the refrigerant bottle. The high side is the smaller pipe on the unit.

Service couplers must be connected to a refrigerant hose and the refrigerant hose must be connected to a manifold gauge set with both low and high side valves in the closed. How to Use AC Manifold Gauges Connect the low side hose blue to the low side port on the AC unit. For discharging a unit you need a disposal hose attached at the center of the manifold HVAC gauge.

To read the AC gauge look at it to read the manometer and so that you can locate yourself when you read 10 they are pounds that is equal to psi now when you ask for the bar they are 145 pounds or psi. If gauges do not read 0 psi remove gauge face and adjust calibration screw to 0 psi. Add only small amounts at a time allowing approximately 10 minutes between each small addition to get a clear reading on the gauges.

The center is where youll be connecting the refrigerant tank. Open only the low side valve on the manifold. Wait 15 minutes before switching your AC back on.

Hook your refrigerant gauge up to the three-valve connections on your AC. You should connect the lower pressure side to the blue pressure gauge using a blue hose. Once all aspects are connected to your AC unit you can release the valve on your Freon container and allow the coolant to circulate in the system.

Only connect the left and right tubes for now. Use the larger black low-pressure hose and a refrigerant recovery bottle attached to the manifold. Do this by loosening but not disconnecting the yellow hose fitting at the top of the manifold gauge set until you hear air hiss out for two seconds.

Complete Procedure To Read AC Gauge. Turn the AC back on and wait 15 minutes so you can get an accurate reading on the gauge. Never open the high side valve on manifold gauge set when the AC System is operating.

If split says in the specification on coolant it is 780g r22 bone 780g 17 pounds. With the engine OFF for at least 30 minutes read the low and high-pressure gauges.
