Transportation And Storage
1- The product is normally packaged individually, and when stored, please carefully repackage the packaging it originally came with. 3.2 At the front thread of the rigid rod, the induction diaphragm is protected by a protective cap, which should be tightened at any time during storage and only opened when using the installation. It is strictly prohibited to press the diaphragm with sharp materials.
2- Long-term storage needs to meet the following conditions:
① Ambient temperature: -20~85℃, relative humidity: 0%~100% R.H.
② Not exposed to rain or affected by water seepage/leakage.
③ Vibration and shock are kept to a minimum.
Product Installation Hole
Before installing the product, make sure that the mounting holes are machined to the correct size and that the holes are free of burrs.
Correct Installation Mode
