INTRODUCTION

The 091-9HP 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

adjusted to start the compressor when the system pressure drops below 110 psi and

stops the compressor when 125 psi is attained. The pressure switch is adjustable.

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

sults from compressing the air. CONDENSATE MUST BE DRAINED WEEKLY.

Please read and follow the installation instructions carefully . The Auto Pump requires no

routine maintenance EXCEPT FOR DRAINING THE MOISTURE TRAP. A careful installa-

tion 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

away from the 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 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 .

DRAIN CONDENSATE SEPARATOR WEEKLY

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 091-9H-1 is available to reduce any vibration and noise from the
Auto Pump and to simplify pump mounting.

VEHICLE WIRING INSTALLATION

1. The Auto Pump is supplied with an unterminated 120VAC CE rated line cord.
