*1: When mounting the pressure gauge, take care not to over-tighten. Excessive tightening will cause damage. Use pipe tape for sealing.
*2: Water is not an acceptable fluid. Before using other fluids, please contact the manufacturer's support center as there may be a corrosion problem.
*3: The set value of the pressure switch is indicated by the pointer (green). It is the point where the circuit between N.O. (white) and COM (black) is turned off during pressure decrease. To set the value, turn the needle in the clockwise direction to the correct value. When setting, if the desired set position has been passed, turn the needle in the counterclockwise direction back again beyond the desired value and then set it again.
*4: Make sure to provide a minimum difference of 0.1 MPa between the set pressure and the operating pressure (including the pressure drop). If the difference is smaller, it could lead to improper operation. See the manufacturer's catalog for details on how to set the setting needle. Note that the operating pressure should be the sum of the pressure of the setting needle error (±0.03 MPa), the hysteresis (0.07 MPa), and the display accuracy (±0.05 MPa) on the set pressure value, or the circuit between N.O. (white) and COM (black) may not turn ON while pressure is increasing.
*5: Maximum error value: Add the pressure gauge indicator error to the setting needle error.
*6: Take care to avoid freezing. This may result in a malfunction.
*7: The guaranteed temperature range is 23°C±5°C.

Procedure for Setting the Limit Gauge Indicator and the Setting Needle
Method 1
(1) Before setting the limit indicator and the (green) setting needle, turn the cover counterclockwise (approximately 6 to 7 mm) until it stops. Then, remove by pulling it towards you.
Method 2
(2) Use a flat head screwdriver (with a 2.9‑mm blade width) to set the (green) limit indicator. Be careful not to bend the other needle or damage the dial plate.
Method 3
(3) Before setting the setting needle, use a flat head screwdriver (with a 2.9‑mm blade width) to turn the setting screw and set the setting needle to the set pressure.
Turning the screw
- Clockwise: increase setting pressure
- Counterclockwise: decrease setting pressure
Method 4
(4) After completing the setting, replace the cover. Fit the cover by aligning the cutout in the cover to the groove on the top of the black case. Turn the cover clockwise (approximately 6 to 7 mm) until it stops. Make sure that the matching mark on the cover is aligned with the groove on the top of the case.
Precautions
Selection
- 1.Do not apply high load voltage (current) or surge current. This can cause the switch to malfunction.
- 2.Make sure that no direct impact or vibrations are applied to the body.
- 3.If operating under pressure pulsations or in high-frequency operations, please contact the manufacturer's support center.
Mounting
- 1. During transport and installation, protect the product from impacts, for example from accidental dropping, etc. This can affect the product's precision.
- 2.Install the product perpendicular to the ground, with the zero point on the reading of the pressure gauge facing down.
- 3.Do not install it in an area that is exposed to high temperature or humidity. This may result in a malfunction.
- 4.To screw in the pressure gauge, make sure to turn the gauge by placing a wrench over the square wrench flats. If the pressure gauge is screwed in by holding it on some other area, air leakage or damage may result.
Other
- *Be sure to read the selection and installation precautions before use.
- *See the manufacturer's catalog for information other than the above.
