General notes
Work on the valve should only be carried out by specialist staff and with the correct tools!
Before working on the system, always turn off the supply voltage!
Clean the piping system before installing the valve!
Where necessary, connect a strainer upstream to protect against faults.
When tightening the connections, never use the coil as a lever!
Ensure that the operational conditions agree with the performance data of the unit!
Avoid back-pressures in the exhaust channels by the use of large-volume silencers!
