how to add freon to rheem air conditioners

Rhine manufacturing in the United StatesS.
Production of air conditioners for residential and commercial use.
The Rhine air conditioner uses refrigerant (usually the trademark of DuPont is HCFC refrigerant Freon) to cool the indoor air.
Ideally, this refrigerant will always remain under pressure within the air conditioning system.
However, over time, leaks occur and refrigerant flows out of a closed system.
After repairing the leak, the technician will add the refrigerant to the air conditioning system, so that the pressure level reaches the working level.
As of 2010, new air conditioning systems manufactured by Rhine group and all other manufacturers may not use freon or other HCFC refrigerants.
Turn on the Rhine air conditioning system on the thermostat.
Move the temperature setting to the lowest level.
Check the internal temperature with a thermostat\'s thermometer.
Open two brass refrigerant service valve covers with an adjustable wrench.
The service valve located on the external unit of the copper refrigerant line entering the Rhine condensate provides access to the refrigerant closure system.
Screw the bottle cap to the heightand low-

When connecting the manifold meter, the pressure refrigerant causes freezing damage to the exposed skin.
Twist the intermediate hose of the refrigerant manifold meter to the freon tank or other brand refrigerant.
The refrigerant manifold meter has three hoses connected to the brass manifold.
The two meters are also connected to the manifold.
The handle on both sides of the manifold operates a set of valves inside the manifold.
High operation of one handle
Low pressure side, one operationpressure side.
Wash the intermediate hose.
Open the cold storage tank.
Open one valve handle of the manifold for two seconds.
Twist the left hose of the manifold to the service valve of the large refrigerant line.
Low left hose operation-
Pressure manifold valves and meters.
Twist the right hose of the manifold to the service valve of the small refrigerant line.
High correct hose operation
Pressure manifold valves and meters.
Open the service panel of the Rhine condensate unit with a nut drive.
There is a temperature/pressure chart inside the service panel located above the refrigerant line.
Use the chart to find the correct refrigerant pressure for the internal air temperature using the pressure/temperature chart.
Follow the \"temperature\" line until the number corresponds to the internal air temperature.
Find the right refrigerant pressure for this temperature.
Add refrigerant if the meter reading is low pressure.
Open the left valve handle of the manifold for 60 seconds.
Close the handle and let the gauge needle settle.
Compare the new meter reading with the temperature/pressure chart.
Continue adding refrigerant until the meter reads within 5 pounds per square inch (psi)
Ideal pressure level.
Dirty coils and filters or improper airflow can have a slight effect on the pressure reading.
Check the outside temperature with a thermometer.
Put this article and
Pressure manifold table readings on the pressure/temperature chart.
Service technicians use this information to determine the overall health of the refrigerant system and to check the compressor and heat exchanger.
Extreme differences require system maintenance and/or repair.
Close the valve of the cold media tank.
Unscrew the manifold hose from the service valve and the cooling agent tank.
Replace the repair panel for the repair valve cover and condenser.
