The AC manifold setup is used to recharge or evacuate the refrigerant from the system and measure the pressures at the low-pressure LP and high-pressure HP lines. It has a brass manifold with 2 pressure gauges - one for the low pressure side marked in blue marked from 0 - psi and the other for the high pressure side marked in red marked from 0 - psi. There is a valve mounted on either side which controls the flow of refrigerant through the 3 threaded ports on the manifold. While charging the refrigerant, the valve next to the LP side is opened and the refrigerant flows from the refrigerant can stored under high pressure just like your LPG cylinder to the system low pressure side in the liquid phase. The manifold has a gauge glass at the centre which shows the flow of refrigerant while charging the setup. Color coded hoses are used to connect the manifold to the system.

You will notice the flow of refrigerant in the liquid phase through the gauge glass on the manifold: Close the valve. Just like the pressure gauges, blue for the LP side, red for the HP side and yellow for charging or evacuating. Evaporator - assumed to be working fine.

While charging the refrigerant, the valve next to the LP side is opened and the refrigerant flows from the refrigerant can stored under high pressure just like your LPG cylinder to the system low pressure side in the liquid phase. I also had a refrigerant top up solution like this CRC , which made the process a lot simpler. The gas will kill any mould and bacteria in the system, which are usually the causes of bad smells. The compressor won't engage! It should be between - psi. Follow the directions for that kit. This sounds too simple, but, it will feel empty. Some gauges have an adjustable "V' on them to highlight the acceptable pressure range.
