Checking Volumes Pumped Per Cycle

See page 21 for information on the AutoPump volumes pumped per cycle. Ensure that
volumes correspond with the previous experience on-site, and with the ranges indicated on
page 21. If it doesn't correspond, then one of the following may exist:
1. The AutoPump is malfunctioning. (See Chapter 7: Troubleshooting & Repair)
2. The Pump Cycle Counter may not be counting correctly. See Appendix F – Pump Cycle
Counter for troubleshooting procedures.
3. Site conditions (e.g. air pressure, discharge head) may have changed substantially.
