Attach the extended interface cables to the Output and Ground terminals using the
unit’s set screws. The RED wire (Pin C on connector) goes to the Output, and

Test the power converter as described below before connecting the interface cable
to its mating connector on the Predatair.
Testing the Power Converter with the Predatair
1. Verify power converter wiring.
2. Re-attach battery/power source and verify voltage polarity on the interface cable
connector with a multi-meter. RED/Pin C (+) to GREEN/Pin B (-) should be nominal
12V.
3. Connect the interface cable connector to its mating connecting on the Predatair.
4. The Predatair display screen will power on and perform SYSTEM CHECK followed
by SYSTEM READY. The warning light on the display box should not be illuminated.
Note:
Perform pre-operation checklist tasks. See Predatair Installation
Manual for details on installation requirements, hydraulic system
requirements, and pre-operation checklist tasks.
5. Enable PTO/hydraulic system. When temperatures are below -15°C, circulate the
hydraulic fluid to warm it before activating the PREDATAIR.
6. Press the ON button. The Ready light should be illuminated. The warning light on
the display box should not be illuminated.
7. Operate the system with an air tool for at least ½ hour. Ensure the Predatair fan
powers on during the test.
Note:
The fan powers on when compressor temperature rises above 88°C. It
also powers on if hydraulic and compressor temperatures are both above
66°C and 77°C, respectively.
8. For the duration of the test, the Predatair should remain powered and the display
box screen show text. (i.e. Predatair should not turn off by itself, nor should the
display box screen go blank when the fan starts/turns-on.)
9.
Press OFF on the Predatair’s display box.
Review the Predatair Owners Manual before using the Predatair.
