2. Attach ground wire using the green ground screw
located inside the electrical box (Figure 2). Connect
the power cable to the brown and blue pump wires
and the control circuit (if required) to the purple wire.

OPERATION
DANGER
To prevent physical injury, observe precautions
against fire or explosion when dispensing fuel.
Do not operate the system in the presence of any
source of ignition including running or hot engines,
lighted cigarettes, or gas or electric heaters.
WARNING
Observe precautions against electrical shock when
operating the system. Serious or fatal shock can
result from operating electrical equipment in damp
or wet locations.
CAUTION
Avoid prolonged skin contact with petroleum fuels.
Use protective goggles, gloves and aprons in case
of splashing or spills. Change saturated clothing
and wash skin promptly with soap and water.
To dispense fuel:
1. Remove the nozzle from the holder. Turn the pump
on by pulling down the switch lever.
2. Insert the nozzle into the receiving tank and squeeze
the handle to dispense fuel.
3. After dispensing fuel, push the switch lever up to turn
the pump off and return nozzle to the holder. The
nozzle may be locked in place to prevent unauthor-
ized use. (Figure 3)
Figure 2
The pump contains an automatic bypass valve to prevent
pressure buildup when the pump is on but the nozzle
is closed. Do not leave the pump on for more than 10
minutes with the nozzle closed.
Never leave the pump running without fluid. Dry running
can damage the pump components.
The pump has a duty cycle of 30 minutes ON and 30
minutes OFF. Do not overheat. Allow the motor to cool
the same length of time it was in operation.
The fuel strainer and check valve assembly should be
cleaned on a regular basis or if low flow rate is noticed.
If the pump becomes too hot, a thermal protector will
automatically shut the motor off and prevent operation
until it cools.
Always turn the pump off if the thermal protector
trips. If left on, the pump will automatically reset
when cool and start pumping.
A. MOTOR DOES NOT RUN.
1. No electrical power to pump. Check breaker,
switchbox and wiring.
2. Thermal protector tripped. Allow motor to cool.
Thermal protector will automatically reset.
3. Rotor or vanes jammed. Remove coverplate and
check for damage or obstruction.
B. MOTOR RUNS, BUT NO FLOW.
1. Tank level low. Add fuel to tank.
2. Clogged filter assembly. Remove and clean filter
assembly.
3. Clogged or broken suction pipe. Remove pump
and clear suction pipe, replace as needed.
4. Broken shaft key. Replace shaft key. Check rotor
or vanes for obstruction.
C. PUMP FAILS TO PRIME.
1. Air leak in system. Check for air leaks at all joints.
2. Bypass valve stuck open. Remove bypass valve
and clean or replace as needed.
3. Check valve stuck open. Remove check valve and
clean or replace as needed.
4. Rotor or vanes worn. Check rotor and vanes for
excessive wear.
CAUTION
Nozzle valve must be stored properly in
nozzle holder (as shown) when not in use.
