8. REFILLING THE REFRIGERANT
Be sure to use R410A as refrigerant.
8-1 PRECAUTIONS FOR ADDING REFRIGERANT
This unit does not require charging, however, so if the piping length is within the lengths shown in the table
below, no additional refrigerant needs to be charged.
The piping length of the refrigerant piping is determined based on the figure following.
In cases where the piping length exceeds that shown in the above table or recharging needs to be performed,
charge as described below.
Be sure to write down the additional amount of refrigerant charged or the entire amount re-charged on the
precaution plate on the rear of the front panel, as this information is needed in case of after-sales service.
8-2 ADDING REFRIGERANT
From the table below, select a refrigerant amount that is suitable for a piping length exceeding the length for
which charging is actually needed. Then add the refrigerant from the service port of the liquid side stop valve.
Select the amount of refrigerant to be added from the table below in accordance with the piping length, and add.
