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.
Belts
Since belts do stretch slightly during the first few minutes of operation, check the belt tension after
completing the operational test; a properly tightened belt will permit twisting the belt 180 degrees
midway between the motor and pump pulleys.
On the 9822A and 9823A, the belt can be tightened by loosening the cap screw which holds the
idler arm and sliding the arm to obtain the correct belt tension of 6-3/4 lbs. (+ 3/4). When the
adjustment is complete, remember to retighten the cap screw.
Calibration
All GASBOY pumps are adjusted for accurate measure at the factory. However, since the
conditions of the installation can affect pump accuracy, it is the responsibility of the installer to
check the pump for accuracy and make any needed adjustments. Where required, 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.
The adjustment of measurement is accomplished
by breaking the seal wire and removing the Seal
Pin. This will permit the Index Disc, to be turned
either counterclockwise (-), decreasing the
measurement, or clockwise (+), increasing the
measurement. A variation of approximately one
cubic inch in measurement is obtained by turning
the Index Disc five holes. After measurement
has been properly adjusted, the Seal Pin and
seal wire should be replaced.
