(see Fig. 5).
Step 2) Turn on the power supply or plug the power
cord into a properly grounded and rated power
source.
Step 3) Start the compressor by turning the OFF/
AUTO knob to the “AUTO” position.
Step 4) At initial start-up, verify that the compres-
sor flywheel is rotating counterclockwise (as
viewed from the flywheel side of compressor).
Watch and listen for excessive vibration and
unusal noise. If either exist, stop the compres-
sor and refer to TROUBLESHOOTING.
Step 5) New compressors should be run with the tank
drain valve open for 1 hour to break-in the
compressor. This will allow the compressor
time to warm up and seat the rings.
