Ok i jus buy a ac chek presure manifold, i wanna recharge mi ac carcompresor but the manual donat said how conect tha house in the r134a can, just said how to chek the presur,, can some one help me with...

To connect the hose to the can, it should have a locking ring with a valve. Some connectors screw on clockwise, and others snap on and clamp downward with a locking lever. To open the can, just turn the T valve down clockwise. To release the freon into the hose, turn the valve to the left. Never remove can from the valve assembly, until the can is empty. If you have no clamp and valve for the freon, just a hose, you can buy one at your local auto parts store

How do i hook my manifold gauges to my residental condensing unit to check pressures

The AC manifold gauges set have the three chambers: the low pressure chamber (left side), utility chamber (middle), and the high pressure chamber (right side).

When technicians connect the HVAC manifold gauge to the air conditioner units, he connects the low pressure side of air conditioner unit to low pressure gauge side.

If he wants to read the pressure in discharge line he connects the high pressure gauge hose to the air conditioner high pressure side.

The utility port (the middle chamber) is a place you connect the hose to vacuum pump, recovery units or add or remove refrigerant from AC units.

Air conditioning gauges is used to measure air conditioner units pressure within closed-system to evaluate or troubleshoot the AC units. Gauges manifold set is the most frequently used item when it comes to refrigerant or pressure.

Air conditioning gauge set allows the HVAC technician to check AC units operating pressures, transfer AC refrigerant, pressure test system, purge the system with nitrogen, and perform other necessary tasks.

The gauges manifold set includes the hoses, the manifold, the valves, the compound gauge (low pressure gauges) and high pressure gauge.

Mobile Mastercool MMB10B set up help needed

It has a float valve so when you connect it to the hose it stays full. The unit holds about 5 gallons but in a hot dry climate that can vanish in an hour or two. A lot of people use a 5 gallon bucket on top of the unit connected to the water inlet with a short hose. It will still need to be filled up but you can run it longer between fills and no hose to trip over.

2000 grand cherokee V-8 stalls out

Start the engine cold and as it warms up, pull the vacuum hose off the EGR valve and see if it keeps running. If it does, replace the EGR valve. The reason the lights are all coming on and the gauges go to zero is because the engine dies and when it starts they return to normal. The EGR valve can stay stuck closed from carbon deposits which is fine for the warm up mode but it needs to open when the engine is warm or it will choke it out. This is not unusual and you will need to replace it. Look on the internet for your make and model an image of your EGR valve it will be easier than explaining it to you. They are in most cases on or connected to the intake manifold or intake plenum.*** Please rate me on this answer.***

Gauge manifold readout interpretation

First of what is the problem taht you are having? To properly diagnose a air conditionign system yoiu have to look at more then just the refrigerant pressures. There is airflow and also duct design and a whole list of other variables. If you haven't done it then my suggestion is to checkout the local colleges in your are and see if they have ight classes to attend to learn more. I had to go to school for 2 years to get my degree and am still learning every day that I am working. thats been 20 years now. Good luck.
