Do not mount in engine compartment or near any source of heat or dirt . The system may be
connected to any point in the vehicle's air system .
2. Mount air compressor in a vertical position as shown.
3. CAUTION no condensate or water must be allowed to enter or accumulate in the output of the
Auto Pump . Route output pressure line downward from Auto Pump to permit moisture to drain
away . Water in the pump outlet will induce failure .
