INTRODUCTION
The Auto-Pump Air Compressor system is a compact electric motor operated single cylin-
der air compressor designed specically for installation on vehicles with air brakes. During
long idle periods of the vehicle when even the slightest seepage can cause an air brake
system pressure to drop below the brake lockup pressure, the Auto Pump automatically
starts to maintain the pressure. The unit also has an automatic water separator that
drains the water from the separator bowl whenever the pump is cycled.
The Auto Pump motor is directly coupled to the compressor section eliminating all belts
and pulleys assuring long life and reliable operation. A heavy duty pressure switch is
adjusted to start the compressor when the system pressure drops below 105 psi and
stops the compressor when 125 psi is attained. The start up pressure is eld adjustable
- the pressure differential between start up and stopping is xed. Please read and follow
the installation instructions carefully. The Auto Pump requires no routine maintenance. A
careful installation will assure years of trouble free operation.
CAUTION
NO CONDENSATE OR
WATER MUST BE ALLOWED TO EN-
TER OR ACCUMULATE IN THE OUT-
PUT

NOTE: Compressor must be
mounted above air tank to assure
that moisture will flow away from
compressor.
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 the 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.
4. All connection 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. Mount the air compressor. Connect a suitable piece of flexible tubing from the outlet port of
compressor to the air tank. (Tubing and connectors are not supplied .)
7. An optional Mounting Plate 091-9H-12V-HP-H, is available to reduce any vibration and noise from
Auto Pump and to simplify pump mounting.
THIS PUMP IS FOR VERTICAL MOUNT ONLY
VEHICLE WIRING INSTALLATION
1. Remove cover of the Pressure Switch on the Auto Pump.
2. Wire the pressure switch to the battery and a good chassis ground, use #14 AWG WIRE
MINIMUM.
3. Reinstall cover of Pressure Switch.
4. The compressor is calibrated to cut-in at 105 PSI and cut-out at 125 PSI . For higher cut-in
and cut-out, turn the range nut clockwise. To lower cut-in turn range nut counterclockwise.
Do not exceed 135 PSI
5. 091-9-12V-HP-VER AUTO PUMP can be wired to a positive or negative system vehicle.
6. Optional switch and fuse can be installed as shown (use 20 amp rated switch and 15 amp
(SLO-BLO fuse).
