MANIFOLD GAUGE HOW TO

Then, you can reattach it with an appropriate refrigerant container. After shutting down the pump, disconnect the yellow-colored hose. When the evacuation is completed, you need to turn off the pump. So, use the blue and red-colored hand valves to open the low and high manifold valves.

After that, connect the yellow hose to the vacuum pump. So, just attach the red hose to the high and the blue hose to the low side. You will notice several colored wires on your 4-way AC manifold gauge. Don't ever vent the stuff directly into the air. Always use appropriate recovery equipment for the refrigerants. To evacuate the refrigeration system, you need to recover all the refrigerants first. Here's how: Step 01: Recover the Refrigerants

MANIFOLD GAUGE HOW TO

All you need to know is just how to hook up ac gauges. You can use your manifold gauge to evacuate the whole refrigeration system, either your car or your AC, at home. Though there are similarities in all of them, you have to know each operation separately. There's a way to figure out whether the system needs charging or not using the manifold pressure gauge.īefore you know how to use four-way AC manifold gauges are set, you need to be aware that there are four situations where you can use the manifold gauges. You can even charge the empty air conditioning system or evacuate it when there's an unknown blend or contaminations in the system using the home AC pressure gauge.

If there are pressure fluctuations in your car's AC, you can just use the hand valves (analog) to adjust it or release the pressure. First of all, you don't need to go to repair shops now and then. Well, there are several reasons behind it. This question might come to your mind of why you should learn to use an AC manifold gauge or what's their purpose in the air conditioning system. And you have to interpret manifold gauge readings based on their types. All you need to do is learn how to read ac manifold gauges R-134A, one of the newest models, and what to do after a condition like low pressure, low charge, etc.Īs an HVAC mechanic, you should know that two types of manifold gauges (analog and digital) are available. However, when it's costly to go and seek help from professionals, you can even use it yourself. It mainly reads the pressure difference in a vessel where the compressed liquid or gasses are put. The manifold gauges are one of the primary refrigeration tools. It's crucial to learn the usage of AC manifolds, or else you might have to go to the repair shop for small and simple things like charging the empty system. After that, the necessary steps vary according to your usage. Then, start the pump or the vehicle to check the pressure readings. You need to connect the red cable or hose to the high side port and the blue line to the low side port. As an HVAC/R technician, you should know how to use AC manifold gauges to adjust/fix your refrigeration system whenever you need.Īn AC manifold gauge can be used in several ways like system evacuation, testing the AC performance, charging a low-charged AC system, and charging an empty system. The manifold gauges are specially used in the AC ventilation system to keep the temperature of your car under control.
