Check pipelines for dirt and clean.
→
Install a dirt filter before the valve inlet (≤ 500 µm).
5.3 installation
note!
Caution risk of breakage!
• Do not use the coil as a lifting arm.
→
Hold the device with a open-end wrench on the body and screw
into the pipeline.
Valve body must not be installed under tension.
→
Observe pin assignment according to switching function and
identification.
