Installation
Note: Depending on your level of expertise, you may wish to have a qualified technician perform this installation.
CAUTION: Avoid damage to the Air Compressor Pump and other equipment. The Compressor Pump mounting platform should be flat, level, and strong enough to support the combined weight of the Pump, electric motor or engine, and related hardware and equipment. It must also be capable of withstanding the vibration and tension of the drive belts. It must incorporate easy access to the Oil Drain Plug (48).
1.Place the Air Compressor Pump on the mounting surface at the same level as the 3 HP motor used to drive it.
Note: Use a motor with the appropriate size pulley to get the needed Pump RPM. For most applications it is recommended to run this unit at the lower RPM.

To calculate the motor and motor pulley needed to power the pump, multiply the Pump Pulley diameter (12.5”) times the pump working RPM (655), then divide by the engine RPM. This will determine the motor pulley diameter (in inches) needed to run the unit.
For example: If you have a 1725 RPM motor, to calculate the pulley diameter needed, multiply 12.5 x 655, then divide by 1725, which equals the motor pulley size of 4.75”. Use the pulley size closest to this figure.
8,187.5 = 4.75”
1725
Or, use the following equation if you have a 3450 RPM motor:
8,187.5 = 2.37”

CAUTION: Misalignment between the Motor and the Pump can cause damage to both the motor and the compressor pump. Use a straight edge, such as a yardstick, to check and adjust alignment as needed.
