Environment

Do not use the product in an environment that is constantly exposed to the splash of water.
Otherwise failure or malfunction can result. Take measures such as using a cover.

Do not use the product in an environment where corrosive gases or fluids could be splashed.
Otherwise damage to the product and malfunction can result.

Do not use in a place where the product could be splashed by oil or chemicals.
If the product is used in an environment containing oils or chemicals such as coolant or cleaning solvent, even for a
short time, it may be adversely affected (damage, malfunction, or hardening of the lead wires).

Do not use in an area where surges are generated.
When a machine or equipment generating large surge near the product (magnetic type lifter, high frequency inductive
furnace, motor, etc.), this can result in malfunction (display of incorrect value), deterioration and damage of internal
elements. Take measures against the surge sources, and prevent the lines from coming into close contact.

Do not use a load which generates surge voltage.
When a surge-generating load such as a relay or solenoid is driven directly, use a Flow switch with a built-in surge
absorbing element.

The product is CE marked, but not immune to lightning strikes. Take measures against lightning strikes
in the system.

Mount the product in a location that is not affected by vibration or impact.
Otherwise failure or malfunction can result.

Do not use the product in the presence of a magnetic field.
Such use can result in malfunction of the product.

Do not let foreign matter, such as wire debris, get inside the product.
To prevent malfunction or failure take measures to prevent the debris entering the product.

Do not use this product in places where there are cyclic temperature changes.
Heat cycles other than ordinary changes in temperature can adversely affect the inside of the product.

Do not expose the product to direct sunlight.
If using in a location directly exposed to sunlight, shade the product from the sunlight.
Otherwise failure or malfunction can result.

Keep within the specified fluid and ambient temperatures range.
If the fluid freezes, it may cause damage and malfunction of the switch, so please take measures to prevent
freezing.
When a fluid at a lower temperature than the ambient temperature is supplied, the product can break due to
condensation and malfunction. Keep the product from having condensation.
Protection against freezing is necessary.
Avoid sudden temperature change even within specified temperature. Otherwise failure or malfunction can result.

Do not operate close to a heat source, or in a location exposed to radiant heat.
This can cause operating failure.
