Reverse Coil Method
When lowering the pump into the well it is important to reverse the natural bend of the
coiled tubing so the tubing will straighten out as it is lowered (see Figure 2-1). As the
pump and tubing are lowered into the well, the direction of the bend should be reversed
from the direction in which it is coiled. If the tubing is allowed to uncoil naturally and the
natural bend not interrupted, the tubing will continue its coil into the well. Using the reverse
coil method will avoid hang-ups or difficulty in lowering the pump into the well, especially
when the well is not vertical, or has come out of alignment for any reason.

Optional Drop Tube Assembly
If a Drop Tube Intake assembly is employed, a third tubing line is necessary to connect
from the bottom of the bladder pump to the top of the Drop Tube intake.
For deployment of optional Drop Tube Assembly, attach desired length of drop tube
between the intake's hose barb and hose barb on bottom of pump. For added security, a
safety cable may be installed to support the drop tube intake to the bottom of pump.
Send the drop tube intake down the well followed by the drop tube tubing, then the pump
and finally the air and fluid discharge lines.
