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 belt.
1. Place the Air Compressor Pump on the mounting surface at the same level as the 3 HP motor used to drive it. Pump positioning must incorporate easy access to the Oil Drain Plug (26).
2. Use a motor with the appropriate size pulley to achieve the needed Pump 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 (1050) which equals 13,125, then divide by the motor
RPM. This will determine the motor pulley diameter (in inches) needed to run the unit.
For example: To calculate the pulley diameter needed for a 1725 RPM motor, multiply 12.5 by 1050, then divide by 1725, which equals a motor pulley size of 7.6 inches. Use the pulley size closest to this figure.

3. The Pump Pulley (47) must be in perfect alignment with the motor pulley (not included). 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.
Note: Ensure the Pump Pulley is installed for counterclockwise rotation when facing the pulley side of the Pump.
4. Verify that the Pump Pulley turns freely where it overhangs the mounting surface.
5. Place a V-groove belt (not included) over the Pump Pulley and the motor pulley.

Installation (continued)
6. Pull the Compressor Pump until properly aligned, and the belt is tight. Recheck the motor pulley, V-belt, and Pump Pulley alignment.
7. Use mounting holes in the Compressor Pump base as a template to mark the spots where four holes will be drilled in the mounting surface.
8. Move the Compressor Pump aside and drill four
5/16" diameter holes in the mounting surface.
9. Move the Compressor Pump back to its mounting position and secure each corner of the base with a 5/16" diameter grade 5 or better bolt, washer, lock washer, and nut (all not included).
10. Make final alignment and adjust belt tension with the motor. It may be necessary to loosen the motor mounting bolts to adjust the motor location. To test the proper tension on the V-belt, press down on the belt — there should be 1/2" deflection or less at mid span. Tighten all mounting hardware.
11. Connect plumbing hardware (not included) from the male 3/4"–14 NPT Air Outlet (51) to the air destination (i.e., air pressure tank of the compressor, not included), routing the tubing in the shortest possible path.
checking the Oil

This warranty does not apply to damage due directly or indirectly, to misuse, abuse, negligence or accidents, repairs or alterations outside our facilities, criminal activity, improper installation, normal wear and tear, or to lack of maintenance. We shall in no event be liable for death, injuries to persons or property, or for incidental, contingent, special or consequential damages arising from the use of our product.

To take advantage of this warranty, the product or part must be returned to us with transportation charges prepaid. Proof of purchase date and an explanation of the complaint must accompany the merchandise.
If our inspection verifies the defect, we will either repair or replace the product at our election or we may elect to refund the purchase price if we cannot readily and quickly provide you with a replacement. We will return repaired products at our expense, but if we determine there is no defect, or that the defect resulted from causes not within the scope of our warranty, then you must bear the cost of returning the product.
This warranty gives you specific legal rights and you may also have other rights which vary from state to state.
