STEP 7- Continue to alternate the air exhaust and the air supply tie-wraps every
two feet, stopping about five feet from the wellhead.
STEP 8- Being careful not to leave any sharp edges, cut the excess from the tie-
wraps.
You now have a down-well bundled hose assembly that supports both the hoses and
the down-well equipment.
AutoPump Installation
Once the installation of the pump support system is completed, you may install the AutoPump
in the recovery well.
Note:
Submerging the pump before supplying it with air will result in fluids
entering the exhaust hose. Those fluids will be discharged from the
exhaust hose during the first few cycles of the pump. If such discharge
will not be confined to the well, the operator may wish to install the pump
with a low air pressure supplied to the pump. To obtain the value of that
low pressure in psi, multiply the number of feet that the pump is to be
submerged by one-half (0.5)
WARNING:
Be sure that the fluid discharge has a closed valve during such process
because the pump may have enough pressure to begin pumping fluid from
the well.
STEP 1 - Lower the pump until it is at the desired level.
STEP 2 - Secure the pump by tying off (securing) the support line or by placing
the well cap on the well.
STEP 3 - Increase the air pressure to the pump until the pump is pushing the fluid
out at the desired rate. With sufficient air pressure (at least 10 to 15 psi
over the vertical static head), the AutoPump will gradually draw down the
fluid level in the well to the level of the pump. The time required for this
draw down varies with the yield of the well as compared to the flow rate
of the pump. The maximum recommended continuous operating pressure
is 130 psi.
