TESTING AND OPERATION
TESTING THE INSTALLATION
Before placing the pump into full operation, you should first test the installation.
1. Place a small quantity of product in storage tank, but do not cover tank or pipe line
connections until pump is operated several times to make certain the system is fully primed
with product.
2.
Operate pump several times, following instructions below, until gasoline is discharged from
hose nozzle. This will fill suction line and pump with gasoline.
3.
Make a final inspection of all pipe lines to insure that connections are absolutely tight.
NOTE: If necessary for more than one pump to be connected to a single outlet from storage tank,
it is imperative that high grade check valves be used in each line to pumps, and must be
placed as close as possible to the connection into main supply line from tank. This is to
prevent a partial vacuum being created in suction lines, causing pumps to operate in a
pulsating manner.
OPERATING INSTRUCTIONS
1.
Reset register assembly to zero by turning instrument knob (located on left side panel) in a
counterclockwise direction.
CAUTION: On units equipped with a built-in interlock, failure to reset register before
attempting to turn dispenser on may result in damage to reset mechanism.

NOTE: Nozzle must be manually held open at all times.
5.
Upon completion of delivery, push switch rod and knob assembly in. This will turn the motor
and pump off.
