ROUTINE MAINTENANCE

Routine maintenance consists of periodically blowing out
the machine, using a low-pressure air stream, to remove
accumulated dust and dirt from the intake and outlet
louvers, and the cooling channels in the machine.
Also verify the STT® Module fan is operational when the
power source fan is activated.
