This AC Manifold Gauge Set can be used to test evacuate and fill automotive air conditioning systems. This AC Manifold Gauge Set is designed to test automotive air conditioning systems using R134A refrigerant only by comparing the high side and low side pressure reading to the vehicle manufacturers AC system specifications.
The center where everything attaches is called the manifold.
How to use ac manifold gauge set. The process begins by twisting both low- and high-side valves on the manifold gauge set to the closed position both on the gauge housing and at the hose ends then connecting the hoses to respective low- and high-side pressure fittings on your vehicle. Once hoses are connected to vehicle fittings open the valves where they attach to the vehicle. A manifold gauge set will have red blue and yellow hoses.
The blue hose goes to the low pressure gauge. The yellow hose can go to either low side or high side depending on which valve is open. The red hose goes to the high pressure valve.
The center where everything attaches is called the manifold. Close all valves on the manual service couplers and manifold gauge set. Connect the high side coupler to the high side port and connect the low side coupler to the low side port.
Turn on the AC system and let it run until gauge readings stabilize. If the pressure shown on the gauges differ from the manufacturers specs determine the problem and make necessary repairs. How to Use AC Manifold Gauges.
Connect the low side hose blue to the low side port on the AC unit. Close all valves on the manual service couplers and manifold gauge set. Connect the high side coupler which is connected to the red hose to the vehicles high side service port and connect the low side coupler.
How to use AC gauges in your car DIY with Scotty Kilmer. How to fix ac problems. How to read and recharge the AC system using pressure gauges.
The AC gauge hoses port are not color coded but the hose is color coded. The blue hoses are used to connect the manifold to the low pressure side central air units suction line. The color coded red mark the high pressure gauges and its connected to the air conditioner unit discharge valve or liquid line valves.
Close both valves on the manifold gauge set by turning the high and low knobs clockwise. The gauges are correctly calibrated at the factory before shipment. If calibration is required insert a straight blade screwdriver into the adjusting screw on the gauge face.
Attach the high and low couplers to the male end of the red and blue hoses. Using a manifold gauge set to diagnose car AC issues. Youll need manifold gauge set if you want to properly diagnose your car AC with gauges.
You cant really diagnose with just a low pressure gauge. Youll also need temperature probes and a multimeter that accepts K-style fittings. For more information about conducting tests using.
Turn on the AC unit at the thermostat and allow it to run for about 20 minutes then turn it off. Connect the blue gauge on the C-manifold to the low side service port on the AC unit. The service hose on the manifold gauge set must have manual or automatic backflow valves at the service connector ends to prevent refrigerant from leaking.
Connect the blue hose to the low pressure port on the AC Connect the red hose to the high pressure port of the AC. Open the valves and take the PSI readings. Mofeez Pro AC AC Diagnostic Manifold Freon Gauge Set.
