AIR COMPRESSOR SYSTEM
MODEL #091-9HP

INTRODUCTION
The 091-9HP Auto-Pump Air Compressor system is a 120 volt 60 Hz split capacitor 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
tostartthecompressorwhenthesystempressuredropsbelow100psiandstopsthecompressor
when 125 psi is attained. The pressure switch is field adjustable. Do not set to a pressure
higher than 130 PSI.
A moisture trap is mounted on the Auto Pump. This captures any condensate which results
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 installation
will assure years of trouble free operation.
NOTE
THIS PUMP REQUIRES A MINIMUM OF 110 VOLTS FOR
OPERATION. AT LOWER VOLTAGES THE PUMP WILL NOT START
