Post Startup Tests
Voltage
The incoming voltage to the pump should be checked and any reading not within 10% of the
rated voltage should be corrected before testing is continued. 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 that
could affect the long term reliability of the unit. Corrective action should be taken to ensure 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 ensure that all connections are tight.
Calibration
All Gasboy pumps are adjusted for accurate measure at the factory. However, since the
conditions of the installation and fuel types can affect pump accuracy, it is the responsibility of
the installer to check the pump for accuracy and make any required adjustments. It is the
owner's responsibility to report this device to the local Weights and Measures officials for their
inspection before the unit is put into service.
