Caution
Disclaimer and Precautions
- VALCOM warrants product against defects for a period of one year from the date of delivery. If the product fails during this warranty period due to any reasons attributed to VALCOM, we will replace the product. However, note that failure of the product due to any of the following will not be covered by this warranty:
(1)Improper handling or use by the customer (including installation or use without following the instruction manual of equipment)
(2)Unauthorized disassembly by the customer
(3)Modification or repair by anyone other than VALCOM
(4)Natural disasters, calamities, riots, disturbance or any other circumstances over which VALCOM has no control.
Please note that the warranty mentioned here means the warranty for the individual product that is delivered. Therefore, VALCOM - Every product is not intended for use with the components or systems that are used in situations where human lives and assets are involved.
Take your own safety measures for minimizing risks even if the products have failed or broken. - VALCOM assumes responsibility for its products only to the extent specified in Warranty in instruction manuals of the respective products. VALCOM shall not be liable to the customers for any damage or loss (lost earnings, business interruption, information loss, recall, etc.) whatsoever caused by failure or breakage of its products. Even when VALCOM is responsible to pay for the damage or loss, the compensation shall not exceed the amount paid by the customer for the product which caused the damage or loss.

Precautions for Use
- Pressure ports must not be touched. Keep your hands away.
- Do not damage or forcibly bend the power, sensor and I/O cables. Doing so can cause a short circuit which may further lead to ignition.
- Use the equipment only within the specified voltage range. Use outside of specified voltage range can result in fire, electric shock or equipment trouble.
- Do not modify or change the equipment and accessories in any way. Unauthorized modification can cause fire, electric shock or equipment trouble.
Such failure or accidents will not be covered by the warranty even if they occur within the warranty period. - Take care to route and connect the wiring properly. Improper wiring can cause poor contact, which may further lead to fire, electric shock or equipment trouble.
- Tighten the bolts to the recommended torque when installing sensor. Always confirm the manual for proper installation. Improper installation can affect the zero point.
- Use the equipment in places that satisfy the environmental requirements described in the instruction manual. Use in severe condition can affect the measuring accuracy of the sensor or cause trouble.
- If measured values fluctuate or different values are shown rather than constant values, influence of noise is likely. Always keep the sensor-mounting part away from the noise source.
- Do not cover the tube hole of the cable containing the venting tube. Doing so can change the zero reference pressure, thus causing zero point output to be unstable.
- If pressure surge exceeding the withstand pressure of the sensor is expected, take measures against pressure surge, or change the pressure range of the sensor.
- Always check the medium to be measured so that foreign matter will not be stuck to the pressure receiver of the sensor. Otherwise, the measuring accuracy of the sensor may be affected, or trouble may occur.
- Install the sensors in places free from strong vibrations. Vibrations can cause equipment trouble.
- When applying pressure, avoid any operations or settings that can cause excessive pressure. Otherwise, the pressure receiver of the sensor may be damaged.
