1. Mount all components in a suitable location, preferably in a high area above the air system.
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 the position as shown being certain that the compressor is above air
pressure tank.
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.
4. All connections for air lines are 1/4" NPT. Use Teflon tape, or equivalent on all connections to
insure no leakage of air.
5. The recommended installation of the Auto Pump air compressor system is shown below.
6. Note that an external check valve is located between the compressor and the pressure switch.
No additional check valve is required.
7. Mount the air compressor. Connect a suitable piece of flexible tubing from the outlet port of com-
pressor to the air tank. (Tubing and connectors are not supplied)
8. An optional Mounting Plate is available to help reduce vibration and noise from Auto Pump and
to simplify pump mounting.
