Cautions For Use

This product is a sensor for detecting leak of fluids.
When this product is used with safety devices, construct the system such that the device itself.

Before using this device, check whether the device performs properly with the functions and capabilities as per the design specifications.
Avoid using this device in an explosive atmosphere because this product does not have an explosive-proof protective construction.

Installation

There is the detection mount difference by directivity of a liquid leakage. When there are a direction from which a liquid leakage happens, and an inclination, please install the nose-of-cam side (opposite side of a cable) of a sensor towards a top.
Use the mounting bracket MS-SQ4-□ (optional) which suits the liquid to detect.
Periodical checking of operation is recommended with the liquids which are not dangerous (water, alcohol, etc.).
The amount of detection may change with the conditions of the installation surface.
Be sure to use the mounting bracket MS-SQ4-□ (optional) when installing this device to avoid human error, etc.
Reliable detection cannot be guaranteed when this sensor is used alone.

Maintenance

Before conduct maintenance, be sure that the system is in safety state.
When using chemical liquid, use proper protections such as groves, masks, goggles, helmets etc. When using protections, be sure to read manuals of them and use properly.
Dispose or reinstall in different environment, flush with DI water.

Mounting

Keep enough space for maintenance when mounting this product.

Leakage detection condition and variation factor

Leak detection part of this product properly detects the leakage in the following condition.

1.	Detection range: Area except backward of this product (liquid must enter to the detection range)
2.	Material of installation surface: Hard vinyl chloride or Stainless steel
3.	Surface condition for installation: Glossy surface (surface roughness: corresponding 0.4 μmRa) and clean surface.
4.	Installation surface angle: Horizontal

This product may not detect properly liquid in following element.

1.	Liquid kind, consistency (surface tension) and air bubble incorporation.
2.	Material, roughness, angle, dirtiness and liquid absorption of surface of installed surface of sensor.
3.	Wrong selection of dedicated mounting bracket.
