Completion Checklist
The information below should be reviewed to help verify the proper installation of the Series
9120Q Compact Commercial Pump Unit. If the installation does not meet criteria listed,
correct the problem before the start-up is performed.
1. The unit must be properly secured to the tank.
2. All plumbing must be complete and tight. All liquid-carrying lines must be checked for leaks.
3. When DC pulsers are used in the pump for connecting to GASBOY fuel management
systems, AC and DC wires should not share any conduits, junction boxes, or troughs.
4. All conduit work must be complete. All junction box covers must be secured. Conduits
should not be sealed until the wiring is verified through proper operation.
5. The unit must be properly grounded.
6. Before any testing begins, remove any water in the tank through a fill opening, using a
suitable pump. Do not use the GASBOY pump to remove water. Serious damage may occur.
7. A sufficient volume of fuel must be put in the tank to insure that the liquid level is above the
bottom of the suction pipe.
Start-Up
After successfully verifying the installation against the completion check list, the unit is ready for
start-up. Follow the procedure listed below to perform an orderly start-up of the Series 9120Q
Compact Commercial Pump Unit.
1. Turn on the circuit breaker(s) for the various control lines to the unit.
2. Remove the nozzle from its holder and turn the crank until register wheels reset to all zeros.
Then turn on the pump handle.
3. Dispense fuel. Check all plumbing for leaks at this time.
4. Turn the pump handle off. Open the nozzle. No fuel should be dispensed.
5. The pump unit should go through all standard calibration procedures.
Post Start-Up Tests
Voltage
The incoming voltage to the pump should be checked and any reading not within 10% of rated
voltage should be corrected before testing is continued. It is good practice to take voltage readings
while the pump is operating on bypass and also while making a delivery. Any voltage drop in
excess of 10% during either of these operating states should be considered a low voltage
condition. Corrective action should be taken to insure an adequate power supply to the pump.
Tightness
After determining that the pump is operating satisfactorily and the system is fully primed, check
the pump and piping to make sure that all connections are tight.
