IMPORTANT: When all 4 LED ’s are off, move thevehicle to an unlevel position so one or two yellowlights are on. Level the vehicle according to the yellowLEVEL lights. Recheck the level. If more adjustment isneeded, DO NOT try to adjust the sensing unit until theyellow level lights go out, instead just "tweak" thesensing unit, ignoring the LED ’s on the sensing unit.

Example: After the initial adjustment and releveling

the vehicle, the front is still low. This means the frontyellow level light is turning off too soon. Determinewhich sensing unit light is the front light, A-B-C or D.Move the adjustment for that light very, very, slightly inthe OPPOSITE direction that is given in the aboveinstructions for LED ’s A, B, C, and D. This will allowthe front yellow light to stay on slightly longer to bringthe front up more. Again, unlevel the vehicle thenrelevel the vehicle using the yellow level lights on thetouch panel. Recheck with a level. Repeat the"tweaking" process until the system levels the vehicleproperly.

The control box sends a +12 signal to the normally open12 volt relay. The 12 volt relay (2) will energize and thecompressor will run. The normally open air solenoid (1)will close allowing the compressor to build pressure.

The normally open air solenoid (1) will open any time thecompressor is not running, allowing internal pressure &moisture to bleed off. The check valve (3) will keep thesuspension air from bleeding back to the compressor.
