Sun Pumps MTR BLM-SB-073S-60 - Manual (Page 8)

3.4 Pump Installation
1. The well should be clean and disinfected before the pump is installed. You should
always clean and develop a new well before installing the pump.
2. Write the pump, motor and controller model number and serial number in the space
provided on the last page in this Instruction Manual. This information will be needed
when filling out the Warranty Card. And will aide in any troubleshooting which may be
necessary.
3. Inspect all components for shipping damage and insure that you have all the components
that are required for a complete installation.
4. Select a well-ventilated, shaded location in which to vertically mount the control box.
The shaded side of the solar panel rack mounting pole is usually a convenient place.
5. If using unthreaded discharge pipe install a stainless steel or brass adapter fitting into the
pump discharge head. Consult your pump supplier for other available adapter materials.
Do not use galvanized connections on stainless steel or bronze discharge heads as
galvanic corrosion will occur. Connect the drop pipe, safety rope and sand shroud (if
used) to the pump. Barbed type connectors should always be double clamped. For poly
pipe, compression fittings are recommended.
6. Splice the drop cable to the motor lead using an under water splice kit. (See wire
splicing instructions provided with splice kit.) Match the drop cable wire colors to the
pump motor leads. If the drop cable does not have the same color wires as the pump, be
sure to record which colors go to the various colors of the motor lead and label them.
The motor can run in reverse if not connected properly.
7. You can now lower the pump into the well. Set the pump at least 10’ off the bottom (see
3.2 System Design Basics #4). Never rest the pump on the bottom of the well. Never
lower the pump by the submersible pump cable.
8. Tie the drop pipe, drop cable and safety rope together every ten feet with 2” 10 mil pvc
pipe wrap tape. Make sure that the tape does not loosen as it will block the pump suction
if it falls down the well. The use of the safety rope is at the discretion of the installer.
9. Slide the well seal over the discharge end of the pipe, connect the discharge fitting, pull
the drop wire through the well seal and connect the safety rope, if used, to the eye-bolt
on the inside of the well seal.
10. Finish lowering the pump and pipe assembly into the well (bore hole) positioning the
well seal over the top of the casing. Connect the discharge pipe to the fitting on top of
the well seal and run the pump wires to the controller.
