Chapter 5: Start Up and Operation
Start Up Checklist
In normal operation, the AutoPump System requires little attention.
Before regulating the air pressure to the desired operating pressure, ensure that the following
conditions exist:
1. Personal Protective Equipment (PPE) is being used by all personnel.
2. The pump is submerged below the fluid level.
3. All hoses are connected.
4. The exterior air filter is mounted vertically to allow the filter and its bowl drain to operate
properly.
5. All out-of-well air and fluid valves are in their correct positions.
6. A method of rapid disconnect and exhaust (or at least a shut off) of compressed air to the
pump is available in case of an unexpected occurrence.
7. When pumping is to begin, either gradually raise the air pressure to the pump or gradually
open the air valve to the pump to allow the pump and hoses to slowly pressurize. Check
for leaks as you do this.
8. As the air pressure overcomes the static and dynamic resistant forces, the pump will begin
to cycle. Listen for the periodic exhaust of air from the pump to determine that the
pump is working. The pump should push fluid out and then exhaust sharply to fill before
pressurizing and pushing the fluid out again.
Cycling can also be monitored by placing an air pressure gauge at the well head and by
observing a pulse counter, if one is present.
9. If a pulse cycle counter is installed, it should be adjusted to accomodate the individual well
conditions. Refer to the PCC manual, Document # 600473.
