Additional Charge of Refrigerant at installation time
Operational steps
Important points
1. The results of all calculations must be recorded. (Make a list.)
2. The refrigerant will need to be additionally charged whenever the distance between the outdoor
unit and the most distant indoor unit is more than 10m.
3. The additional charging operation should be carried out by input of liquid from Service port at
liquid stop valve following completion of the vacuum drying operation.
4. When the additional charging operation cannot be satisfactorily completed use the action of the
compressor to complete the additional charging during the test run.
Refrigerant
Charging
Instructions
HFC401A are Quasi-azeotropic* refrigerants. Therefore, these refrigerants must be charged in the
liquid state. When charging the refrigerant into equipment from the refrigerant cylinder, turn the
refrigerant cylinder upside down.
Important: Make sure that the refrigerant (liquid) is taken out from the bottom part of the refrigerant
cylinder. Do not take out the refrigerant (gas) at the upper part of the refrigerant cylinder for
charging.
Caution
Since some refrigerant cylinders differ in the internal mechanism, it is necessary to examine the
cylinder carefully. (Some cylinders have a siphon tube to eliminate the need for turning it upside
down.)
Use the length of the piping to
calculate the amount of
refrigerant required
