AP-2 Manual

Observation of System Operation

Observe the system operation for at least 10 pump cycles to ensure everything is working.
If the well influx is low so the pump seldom cycles, pour clean water into the well to check
on the pump. If allowed, the pump discharge can be directed into the well so the pump will
cycle within an acceptable period to allow for observance of operation. Check your local
regulations to determine if these practices are permissible.
Note:
The Pump Cycle Counter may have to be readjusted if it is set when the
water is recirculating to the well.
After the entire site is operating, return to each well to ensure that the pump and PCCs are
functioning properly. The addition of other pumps and possible system back pressure can
necessitate air pressure and counter readjustment.

Downwell Testing of the AutoPump

While the AutoPump is in the well, it can be tested by putting compressed air into the exhaust
hose of the pump.
Note:
The air supply hose must be shut off or pressurized when this is done.
The compressed air will enter the pump through the exhaust valve and push any fluids in the
pump up the discharge tube. If sufficient compressed air is continually supplied, it will also
exit the discharge tube and cause the fluid in the discharge hose to be airlifted to the surface.
This method can be used to lighten the pump and hoses before removing the pump from the
well. This process can also show whether the fluid inlet check valve is sealing and if the pump
is capable of discharging fluid.

AutoPump Shutdown while Submerged

The AutoPump can be submerged for long periods of time at most sites. If the well
environment is such that deposition occurs on stainless steel parts, the operator may wish to
raise the pump above the water level during a shutdown of the system.
