INSTALLATION
• The OM4A motor was designed to work only submerged.
• Don´t move the motor by its cable since this could damage it.
• After mounting the pump, check that the shaft turns freely.
• Choose the installation cable according to the table on the next page.
• Affix the cable on the eductor tube to avoid damage.
Make sure that the motor doesn´t touch the bottom of the well! The
sand could damage the diaphragm. Therefore, keep the motor at
least one meter above the bottom of the well.
