６．３ Warning & Caution For Installation - Yoshitake DP-10 Series Instruction Manual

６．３ Warning & Caution for Installation
Warning
（１） When there is a risk of having life hazard, harming a body or property by the
malfunction of the solenoid valve, please install the safety device which operates
interception, opening, warnings on the basis of machinery or device.
（２） The Valves is not for explosive atmosphere.
* It is not explosion-proof construction.
（３） Carry out the cable connection only after confirming that no power is supplied.
* May cause an electric shock.
（４） Carry out the connection after confirming the rated voltage and follow to the
instruction.
* Erroneous cable connection may cause an electric shock or fire.
（５） Do not turn on electricity without coil on solenoid valve.
* May result in fire caused by an over current.
Caution
（１） For piston type solenoid valve, the minimum differential pressure between inlet
and outlet side must be more than 0.05MPa.
* May result in an abnormal operation.
（２） Vertical or horizontal installation is possible, but the coil must be installed above
the horizontal level.
* May result in a short circuit.
（３） When using less than 0.1MPa pressure, the solenoid valve should be installed
horizontally with the coil up.
* May result in an abnormal function.
（４） Remove foreign matter and scales from the lines before connecting the valve.
* Failure to do so may prevent the valve from functioning correctly.
（５） In case specifying installing direction, install inlet and outlet correctly.
* Failure to do so may affect the original performance.
（６） Install a strainer (Recommendation: 80-100mesh) at the valve inlet side.
* Failure to do so may prevent the valve from functioning correctly.
（７） Do not apply excessive load, torque or vibration to the valve.
* Doing so may result in malfunction or drastically shortened service life.
（８） Provide space around the valve so that the valve can be easily disassembled and
inspected.
* May not be able to do the maintenance.
（９） When using in the outdoor, set the eaves at the product to keep rain away from
the products and treat waterproof at the wire connection part.
* May result in a short circuit.
（10） Do not apply insulation around the solenoid coil.
* May cause an abnormal function.
