AutoPump Shutdown and Removal from Well
To shut down and remove the AutoPump, follow these directions:
STEP 1 - Wait until the pump is in its discharge cycle and then raise it above the
water level in the well. This will empty most of the fluid from the pump
making it lighter to lift. There will also be less fluid to drain from the
pump.
Note:
See Start Up and Operation for optional pump removal technique.
STEP 2 - Pull the pump and hoses to the surface.
STEP 3 - Shut off the air to the pump and disconnect the air hose from the pump.
STEP 4 - Ensure that there is a safe place to drain any fluid from the pump and
discharge hose.
STEP 5 - Disconnect the fluid discharge hose from the pump.
STEP 6 - Drain the fluid by turning the pump upside-down and allowing fluid to
flow from the air inlet fitting.
Caution:
Wear gloves and catch the draining fluid in a sump or bucket.
Removing Pump Casing
Follow these instructions for removing the pump casing:
Caution:
When assembling or disassembling the pump, do not rotate the casing. If
the casing is turned and if any resistance is felt, stop. This action may cause
the float and control rod to rotate with the casing. Instead of rotating the
casing, spin the bottom check valve (or plug on a Top-Loading pump) and
hold the casing stationary.
Caution:
After troubleshooting is completed and before assembling the pump, slowly
move the float through its range to ensure that the lever trips, even if the
pump fills and empties slowly.
