Installation Instructions:

Before installing motorized pump unit, check incoming voltage to be certain it does not exceed motor rating as this will result in motor damage. Instructions for electrical connection are on a decal on the motor housing. Qualified or trained personnel should install equipment. Equipment should be installed in accordance with the National Electrical Code, local codes and with NEMA MG1, Safety Standards for Construction and Guide for Selection, Installation and use of Electric Motors and Generators. Review your application flow and pressure requirements. Exceeding the rated pressure of the motorized unit may cause overheating of your motor, high amp draw and result in shortened motor life. See the data sheet under the Manuals tab for steps on how to assemble the electric motor and pump.
