Installation
Installation, inspection, maintenance, repairs, disassembly, adjustment and valve opening/closing should
be carried out only by trained maintenance personnel.
1. The joint and the siphon tube are temporarily connected when shipped. Make sure to retighten when
installing the product before use.
Make sure to retighten the joint and siphon tube. If retightening is not carried out, steam
or hot fluid may leak, resulting in malfunction of the product and leading to burns or other
injury.
CAUTION
2. Make sure to use the siphon tube if the operating fluid temperature is 85
C or more.
3. Make sure to use the joint, as the siphon tube cannot be installed without it.
4. Do not put any stress on the diaphragm inside the pressure receiving part.
5. Supply voltage of DC10 to 30V is required for operation. When the product is used with instruments that
do not have a built-in sensor power supply (controller, recorder, indicator, etc.), provide the power
supply for the sensor separately.
6. Ensure that the wiring is carried out with the correct polarity by referring to figures below.
7. Ensure that all the screws for the cover and the wiring connection are firmly tightened once the
installation and the wiring are complete.
