Method of opening/closing a valve
• Remove the cap, turn the gas pipe side until comes to the “Closed”
position as indicated in the drawing on the right.
• For the liquid side pipe, turn with a hexagonal wrench until the shaft
stops. If excessive force is applied, the valve main body can be dam-
aged. Always use a dedicated special tool.
• Tighten the cap securely.
For tightening torque, refer to the table below.

(4) Refrigerant charge
S Models FDCA301~601
(a) The outdoor unit is charged with enough refrigerant for a piping length of 30 m when it is shipped from
the factory, and additional charging is not necessary in the case of a system with 30 m or piping or less.
(b) If the system’s piping exceeds 30 m, charge with an amount of additional refrigerant corresponding to the
additional length of piping in the system.
(Example) If the FDCA301 model is newly installed and the piping length is 45 m.
Additional Charge Amount: 0.60 kg = (45 – 30) m 0.040 kg/m

Notes (1) The standard refrigerant charge volume shows the charge volume with the length of refrigerant piping is 0 m.
(2) Concerning the additional charge per meter of piping and the refrigerant charge volume when the unit is shipped from the factory, as shown in the above
the unit is charged with a portion of the refrigerant needed for the local piping, so be sure to calculate the amount of additional charge that is needed and
charge the system locally.
