INTRODUCTION

The 091-9B-1 Auto-Pump Air Compressor system is a 220/240 volt 50/60 Hz shaded pole

A.C. motor operating a single cylinder air compressor designed specifically 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 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 70 psi and stops the compressor

when 90 psi is attained . The start up pressure is field adjustable - the pressure differential

between start up and stopping is fixed.

A moisture trap is mounted on the Auto Pump. This captures any condensate which results

from compressing the air. In addition, the moisture trap in combination with the check valve

and the unloader on the pressure switch permits the Auto Pump to start "unloaded". This

reduces the load on the motor and permits starting at the higher system pressures.

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.

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 a vertical position as shown.

3. CAUTIONno condensate or water must be allowed to enter or accumulate in the output of the

AutoPump. RouteoutputpressurelinedownwardfromAutoPumptopermitmoisturetodrain

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. Note that an external check valve is located beteen 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

compressor to the air tank . (Tubing and connectors are not supplied .)

8. An optional Mounting Plate 091-9H-1 is available to reduce any vibration and noise from Auto

Pump and to simplify pump mounting.

NOTE: Compressor must be mounted above air

tank to assure that moisture will flow away from

compressor.

VEHICLE WIRING INSTALLATION

1. The Auto Pump is supplied with a 220/240 volt A.C. line cord and is ready to operate. The

line cord may be plugged into an available outlet or the cord may be cut and permanently

wired to the 220/240 volt A.C. system in the vehicle.

2. The compressor is calibrated to cut-in at 70 PSI and cut-out at 90 PSI . For higher cut-in

and cut-out, turn the range nut clockwise . To lower cut-in turn range nut counterclockwise .

Do not exceed 100 PSI .

COMPRESSOR OUTPUT IS 100 PSI MAXIMUM. DO

NOT EXCEED 100 PSI OR YOU WILL VOID

WARRANTY.
