INTRODUCTION
The 091-9B-4-AD Auto-Pump Air Compressor system is a 120 volt 50/60 Hz split capacitor
A.C. motor operating a single cylinder air compressor designed specically for installation
on vehicles with air brakes. During long idle periods of the vehicle when even the slight-
est 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 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 ad-
justed to start the compressor when the system pressure drops below 75 psi and stops
the compressor when 95 psi is attained. The pressure switch is adjustable.
A moisture trap is mounted on the Auto Pump. This captures any condensate which
results from compressing the air. The Auto Drain will automatically drain the
condensate when the pump turns o󰀨.
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.
NOTE
THIS PUMP REQUIRES A MINIMUM OF 120 VAC FOR
OPERATION. AT LOWER VOLTAGES THE PUMP MAY NOT START

VEHICLE TUBING INSTALLATION
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 horizontial 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 connections for air lines are 1/4" NPT . Use Teon 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 exible tubing from the outlet port of
compressor to the air tank . (Tubing and connectors are not supplied.)
8. An optional Mounting Plate 091-9HP-H is available to reduce any vibration and noise from the
Auto Pump and to simplify pump mounting.
