PACKAGE LIST 1 x 5HP Compressor Duty Electric Motor 1 x Manual Please Feel free to contact us with any questions you have relating to our products. Kindly Tips: 1. Amperage Please make sure your FL amp (FULL LOAD) rating on the motor you're replacing is within 10% of the FL Amp rating of the motor you intend to buy. 2. Frame Size The frame not only constitutes the bolt pattern, it also depicts the overall size and torque. The larger the frame, the stronger the motor. Improperly sized motors will inevitably result in motor failures. 3. Phase and Voltage If your machine requires a 230V electric motor on single phase power. 230V electric motors cannot handle voltages less than 208V. They will run too hot and you will experience motor failure. 4. RPM Matching up the RPM is quite important. The wrong speed can damage your pump. The RPM does not have to match exactly, but you do need to be the neighborhood. Example: 3510rpm, 3550rpm, 3450rpm are all the same. They are all fall under the umbrella of whats known as 3600RPM motors. 5. Shaft Diameter With a tape measure. Measure the outside diameter on your electric motors shaft. By matching up the proper shaft diameter, you will be able to reuse the original motor pulley that came on your machine.
