Procedures for charging additional refrigerant.
Additional refrigerant charge procedure (2)-by Additional refrigerant charge operation
About the system settings for additional refrigerant charge operation, refer to the [Service
Precaution] label attached on the electric box cover in the outside unit.
1. Fully open all shutoff valves (valve A and valve B must be left fully closed).
2. After ten minutes, fully close liquid line shutoff valve and then, open the valve by turning 180°.
Start the additional refrigerant charge operation.
See [Service precautions] Label for detail.
If it is difficult to charge the refrigerant additionally, decrease the water temperature or warm
the refrigerant tank.
(Warm the refrigerant tank with a stupe or a warm hot water of 40 degrees or less.)
3. After the system is charged with a specified amount of refrigerant, press the RETURN button
(BS3) on the PC board (A1P) in the outside unit to stop the additional refrigerant charge
operation.
4. Immediately open both liquid-side and gas-side shutoff valve.
(If do not open the shutoff valve immediately, liquid seal may cause the pipe to burst.)
Shutoff valve operation procedure
Caution Do not open the shutoff valve until checking of device and installation conditions are completed.
If the shutoff valve is left open without turning on power, it may cause refrigerant to buildup in
the compressor, leading to insulation degradation.
Opening shutoff valve
1. Remove the cap and turn the valve counterclockwise with the hexagon wrench (JISB4648).
2. Turn it until the shaft stops.
Do not apply excessive force to the shutoff valve. Doing so may break the valve body, as the
valve is not a backseat type. Always use the hexagon wrench.
3. Make sure to tighten the cap securely.
Closing shutoff valve
1. Remove the cap and turn the valve clockwise with the hexagon wrench (JISB4648).
2. Securely tighten the valve until the shaft contacts the main body seal.
3. Make sure to tighten the cap securely.
* For the tightening torque, refer to the table on the next page.
