Service Tips
• Remove and replace the meters using metric tools.
• Place an approved pan under the meter during repairs to collect the residual fuel.
• Inspect all gaskets during off-unit repairs. Replace the meters, as required.
• Some meter bolts are difficult to access. A 13-mm universal socket makes installation and
removal easier.
• For calibration procedures, refer to
“LC Meter Calibration Adjustment for Ultra-Hi
.
• Non-use of strainers can significantly reduce the meter life.
• Meter failure may be indicated by a significant change in calibration from high to low
flow rate, excessive calibration spread, or meter stall at low flow.
Note: Other problems may also cause the same symptoms.
• After replacing a meter, always purge the system of air (refer to
on
) and recalibrate the unit.
• Calibration problems are not always caused by meters. Dispenser check valves and
leaking nozzles may also cause calibration problems.
