Opening shutoff
valve
1. Remove the cap and turn the valve counterclockwise with the hexagon wrench.
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 special tool.
3. Make sure to tighten the cap securely.
Closing shutoff
valve
1. Remove the cap and turn the valve clockwise with the hexagon wrench.
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 below.
Tightening torque
CAUTION
Always use a charge hose for service port connection.
After tightening the cap, check that no refrigerant leaks are present.
When loosening a flare nut, always use two wrenches in combination.
When connecting the piping, always use a spanner and torque wrench in combination to tighten
the flare nut.
When connecting a flare nut, coat the flare (inner and outer faces) with ether oil or ester oil and
hand-tighten the nut 3 to 4 turns as the initial tightening.
