Installation
CAUTION
Do not freeze this product.
Doing so may damage the valve body and cause leakage.
When piping this product, be sure there is no foreign matter in the pipes.
If foreign matter remains in the pipes, the product may break down.
Install and use this product under the conditions specied by this manual.
Failure to do so may cause device failure.
Installation location
• To remove foreign substances inside the pipes, install a strainer on the inow side of each valve. In case that the strainers
cannot be installed on the inow side of each valve, install it on the pipe diverting sections (sections diverting from main
piping system to sub piping system).
•Do not install the product nearby a steam coil, pressurized hot-water coil, or any high heat source. High temperature
radiation might cause malfunction of its actuator.
•Do not mount the valve on a pipe where water hammer occurs, or where solid objects including slug may accumulate.
• Install a bypass pipe and gate valves on the inow, outow, and bypass sides. Also, install a strainer (with 40 or more meshes)
on the inow side.
•Install the valve assembled with the actuator in a position allowing easy access for maintenance and inspection. Fig. 1 shows
the minimum clearance for maintenance and inspection. When installing the valve and actuator in a ceiling space, provide an
access panel within the 20” radius of the valve and actuator. And, place a drain pan under the valve.

Mounting position
The valve (assembled with the actuator) can be mounted in any position ranging from upright to sideways (90° tilted). The
valve should be installed with its actuator vertically positioned above the valve body. However, the valve must be installed
always in upright position outdoors.

Piping
CAUTION
Do not screw a pipe excessively far into this product.
Doing so may damage the inside of the valve and cause leakage outside of the valve, or may cause malfunction.
• Install the valve so that the  ow direction of process  uid agrees with the arrow indicated on the valve body.
•When installing the valve to pipes, do not allow any object, such as chips, to get inside a pipe or valve. Valve cannot fully
closes, or the valve seat may get damaged causing  uid leakage, due to an foreign object jammed inside the valve.
•When piping, do not apply too much sealing material, such as solidifying liquid and tape, to the pipe connection sections
so that these materials  ow into the valve. Valve cannot fully closes, or the valve seat may get damaged causing  uid
leakage, due to the sealing material jammed inside the valve.
•When connecting the valve to pipes, hold the valve body (where a pipe is screwed) with a tool such as a wrench, and
screw the pipe into the valve. (See Fig. 5.) Do not apply excessive torque to the pipe. Refer to the table in Fig. 5 for the
recommended torque.

• Before activating the valve and actuator,  ush the pipes (with the valve and actuator installed) at the maximum  ow rate to
remove all the foreign substances. Fully open (in 100 % position) the valve to  ush. (Factory preset position: 100 %)
CAUTION
After installation, make sure no  uid leaks from the valve-pipe connections.
Improper piping may cause  uid leakage outside of the valve.
