WARNING
This product weighs 18 kg or over (depending on the models). To prevent hazardous accident and severe injury,
move or carry the product with enough manpower or using a vehicle.
Do not disassemble the product. Disassembly may result in electrical shock or equipment damage.
CAUTION (1/2)
Installation and wiring must be performed by qualified personnel in accordance with all applicable safety
standards.
Disconnect power from ACTIVAL before performing any wiring, maintenance (installation), and setting the selector
switches to prevent equipment damage.
All wiring must comply with local codes of indoor wiring and electric installation rules.
Use crimp terminal lugs with insulation for electric wires to be connected to the screw terminals.
Make sure all the wires are tightly connected to the screw terminals. Loose connection may cause fire or heat
generation.
Always close the top cover and the terminal cover except when setting the selector switches and connecting/
disconnecting wires.
Install the ACTIVAL in the position as specified in this manual. Excessively tight connection of the valve to a pipe
and improper installation position may cause valve damage.
Do not install the ACTIVAL in a location close to a steam coil or a hot-water coil. High temperature radiation may
result in an actuator malfunction.
After installation, make sure no fluid leaks from the connecting parts of valve and pipes. Incorrect piping may
cause fluid leakage.
Do not allow any foreign substance inside the piping. Flush the piping so that no foreign substance remains.
Attach a strainer with 40 or more meshes (80 or more meshes recommended for steam control) in a pipe on the
inflow side of the ACTIVAL to prevent equipment damage.
This product must be operated within its rated operating ranges specified in this manual. Failure to comply will
cause equipment damage.
This product must be operated under the operating conditions (power, temperature, humidity, vibration, shock,
installation position, atmospheric condition, etc) specified in this manual to prevent equipment damage.
Avoid using the ACTIVAL (actuator, valve, and other components) in a corrosive gas including oxide gas and
explosive gas.
Set the selector switches using a pen nib or fingers. Do not use a tool such as a screwdriver. Such a tool can
damage the selector switches or the PCB.
To operate the ACTIVAL with small dead band, provide shielded cable for input/output signal lines and power line.
Unshielded cable can cause error due to noise.
