INTRODUCTION
The 091-9B-1 Auto-Pump Air Compressor system is a 120 volt 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.
