How to troubleshoot a Sumitomo F-20L that won't start?
If your Sumitomo Air Compressor and connected devices aren't starting, first, ensure the power source is switched 'ON' and the power cord is properly connected. Then, check the compressor's circuit breaker and reset it if it has tripped. If the issue persists, or if there's an open fuse in the control circuit, check for any short circuits and replace the fuse.
Why are gas pressures abnormal in my Sumitomo F-20L Air Compressor?
If your Sumitomo Air Compressor system starts but the gas pressures are not normal, check the equalization pressure against the specifications and the section on Charging and Venting. If the pressure is low, check the system for leaks. Also, ensure all Aeroquip couplings are fully engaged and properly torqued. Verify that the gas lines are connected correctly according to the Installation section.
What to do if Sumitomo F-20L Air Compressor starts then shuts down quickly?
If your Sumitomo Air Compressor starts but shuts down after a few minutes, the issue could stem from several causes. Check the equalization or operating pressure against the specifications. If the pressure is incorrect, refer to the Charging and Venting section. If the pressure is low, perform a leak check on the system. Another potential cause is a failed gas equalization solenoid valve, which would need replacement. Low oil flow can also cause this issue; inspect the compressor capsule for oil leaks. Lastly, a blocked orifice or oil cooling line filter could be the culprit, requiring replacement of the orifice and filter.
Why does my Sumitomo F-20L shut down after running for a while?
If your Sumitomo Air Compressor starts but shuts down later, check the coolant flow and temperature, referring to the Specifications. Also, reset the circuit breaker or replace the fuse if it's open, comparing the electric service with system specifications. Check for an open circuit breaker or fuse and reset or replace if necessary, and check for any faulty components in the power circuit. Measure the current and check motor winding resistances. If water and power checks indicate the utilities are within specifications, interlocks may be faulty.
