# Locker engages as soon as compressor is turned on.

When the compressor is turned on and the locker engages, check the orientation of the solenoids and where  the air fitting is installed. If they are in line from one another the solenoid is being bypassed and allowing direct air pressure to the locker. The air output fitting will need to be moved to the port 90 degrees offset from the air input.
