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. Make
sure the mounting surface for the Air Compressor Pump is installed on a flat
and level surface, strong enough to support the pump and motor.
1. Place the Air Compressor Pump on the mounting surface at the same level as the 3
HP motor used to drive it. The 14-¼ inch V-groove Belt Wheel (35) of the Air
Compressor Pump must be in perfect alignment with the motor pulley (not included).
2. Verify that the Belt Wheel (35) turns freely where it overhangs the mounting surface.
3. Place the V-groove belts (not included) over the Belt Wheel (35) and motor pulley.
4. Pull Compressor Pump until properly aligned, and the belt is tight. Recheck
motor pulley, V-groove belt, and Belt Wheel alignment.
5. Use a pencil to mark through the Air Compressor Pump mounting holes onto
the mounting surface.
6. Move the Air Compressor Pump and drill four 3/8 inch holes in the mounting surface.
7. Move the Air Compressor Pump back to its mounting position.
8. Secure each corner of the base with a 3/8 inch diameter bolt, washer, lock
washer, and nut (all not supplied).
9. Make final alignment and belt tightness adjustments from 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-belts, press down on the belts, they should
not depress more than 1/2 inch at mid-point. Tighten all mounting hardware.
10. Mount the motor (not supplied) as recommended by the motor manufacturer.
Be sure that the motor is securely mounted.
11. Connect plumbing hardware (not supplied) from the male ½” - 14 tpi Air Outlet
(6) to the air destination (i.e., air pressure tank, not supplied).
12. Install a safety guard (not supplied) that surrounds the motor pulley, V-belts,
and Belt Wheel (35). This safety guard must cover all sides of the moving
belts and pulleys. It should have a clearance of about one inch from the
moving parts. The safety guard must be sturdy enough to prevent injury.
