1. Prepare a rechargeable exclusive refrigerant container, a scale, and a Manifold gauge.
2. Check the amount of refrigerant remaining in the overall system at the time.
3. Connect the refrigerant container to the outdoor unit as shown in the following figure, and operate only about 50% of the total
indoor units in air conditioning mode.
4. Check the high pressure from the Manifold gauge 10 minutes after the air conditioning begins operation.
Reduce the number of indoor units in operation if the high pressure goes above 30kg/cm2,g. to lower the high pressure below
30kg/cm2,g.
5. Check that the high pressure goes below 30kg/cm2,g, and open the Manifold gauge connected to the liquid pipe, as well as
the refrigerant container valve, so that the refrigerant flows from the liquid pipe to the refrigerant container.
6. Check the changes in the weight of the container using the scale. Once the desired amount of refrigerant is filled up inside the
container, close the valves, and then remove the Manifold gauge.
7. The amount of refrigerant that can be contained inside the container is about 50% of the amount of refrigerant inside the over
all system.
8. Please take extra caution by precisely determining the amount of the refrigerant that can be put in each container so that too
much refrigerant is not contained in the container.
The weight must be measured by using a scale to avoid putting more refrigerant than the amount originally contained in the
container.
