1. Check that the pump and motor mounting faces are
free from dirt.
2. Assemble the pump liquid end and motor together
so that mounting faces are in contact. Then tighten
assembly bolts evenly in a crossing pattern.
NOTE: Apply non-toxic FDA approved waterproof grease
such as Mobile 102, Texaco CYGNUS2661 or equivalent
to the coupling before assembly of pump coupling to
motor shaft. This will prolong spline life and prevent
abrasives from entering the spline area.
3. Check for free rotation of the pump and motor. A
slight drag is permissible.
4. Assemble the pump lead guard over the motor leads.
Do not cut or pinch lead wire during
assembly.
5. Assemble suction screen to pump mounting ring.

PRE-INSTALLATION
To save possible added expense and extra trips, observe
and complete as many as possible of the following
precautions and pre-installation procedures before going
to the job site or beginning the installation.
IMPORTANT PRECAUTIONS
1. Prior to installation, inspect the pump for damage.
Check for free pump and motor rotation. A slight drag
is permissible.
2. Check to make certain that the voltage of the motor
end and controls agree with the available phase
and voltage. Check power source. Check electrical
supply for correct fusing, correct wire size, and
adequate grounding and transformer size.
Since most submersible pump problems
are electrical, it is very important that all electrical work
be done properly. Therefore, all electrical hook-up work
or electrical service work should be done by a qualified
electrician or service man only!
3. Throughout installation, take care not to damage
the insulation of the electrical cable or motor leads.
Never support the weight of the unit by electrical cable
or motor leads.
4. Before the pump is installed, the well should be
pumped free of sand and other foreign matter with
a test pump. The warranty is void if it is used to
clean the well.
