Trouble Shooting

CAUTION
Before any maintenance work on the compressor, make sure there is not air inside, under pressure.
Every time you stop the compressor, ALWAYS open the manual drains so as to remove condensate.
Maintenance work on the compressor must always be done with the compressor stopped and disconnected from
the mains supply. Never forget to open the manual drains, after stopping the compressor.
Especially when you are planning to clean the solenoid valves (auto drains version), always turn off the main
electrical supply.
You must always have in mind, if you disconnect the coil of the solenoid valves, without turning off the electrical
supply, it will be destroyed immediately!!!
