cables at plugs, and the point where they exit from the PL-PRO. To prevent risk of
fire or injury, damaged cords and cables should be replaced immediately.
7. Clean the PL-PRO with a damp cloth only. Do not use solvents or abrasive
cleaners. Never pour any liquid on or into the PL-PRO.
8. When left unused for a long period of time, the power cord of the PL-PRO should
be unplugged from the outlet.
9. The PL-PRO should be serviced by qualified service personnel when:
a. The power supply cord or the plug has been frayed, kinked, or cut.
b. Objects have fallen or liquid has spilled into the unit.
c. The PL-PRO has been exposed to rain or other moisture.
d. The PL-PRO does not appear to operate normally or exhibits a marked
change in performance.
e. The PL-PRO has been dropped, or the enclosure damaged.
10. The PL-PRO requires that a safety ground be present for proper operation. Any
attempt to operate the PL-PRO without a safety ground is considered improper
operation and could invalidate the warranty.
11. Light bulbs are the only user-serviceable parts in the PL-PRO. Instructions for
replacing them are on pages 6-7. The light tubes and end caps become quite warm
to the touch in normal operation. To avoid burning your fingers, allow the cap to
cool completely before unscrewing it. If you find that the heat from the tubes is
excessive, try reducing the setting of the dimmer knob.
12. Do not attempt to service the PL-PRO beyond what is described in this manual.
All other servicing should be referred to qualified service personnel.

Power Status LEDs
The PL-PRO's status LEDs inform you
of abnormal conditions at a glance:
Symptom:
PROTECTION OK Indicator not lit.
Possible Cause:
Protection devices are damaged.
Action Needed:
Factory service.
Symptom:
GROUND OK Indicator not lit.
Possible Cause:
No building ground, bad outlet.
Action Needed:
Locate good ground, run ground wire.
Symptom:
All voltmeter LEDs are flashing.
Possible Cause:
PL-PRO is receiving 130-140 volts. (If only the LED under the
90V mark is flashing, PL-PRO is receiving 80-90V).
Action Needed:
Correct the line voltage. Consider installing a Furman
voltage regulator.
Symptom:
EXTREME VOLTAGE Indicator flashing.
Possible Cause:
Input voltage is below 80 or above 140 volts, causing power to
the PL-PRO's outlets to be shut down.
Action Needed:
Correct the line voltage. Consider installing a Furman voltage
regulator.
Voltmeter Displays
The PL-PRO informs you of voltage problems at a glance. The following chart
