voltage. Make sure the input power
source meets the power requirements for
the unit per Section 2, Specications.

Power On
Place the Power Supply ON / OFF switch to the
ON (up) position. AC indicator turns on.

pressure for power supply operation and the cool-
ing fans turn on.

condition occurs, the fans will continue to run
while the condition exists and for a ten (10)
minute period once the condition is cleared.
