3. Insert the top of the Mini Air Filter through the Mounting Bracket and secure by replacing the Retaining Ring.

4. Attach a 1/4” NPT Female hose connector to the air compressor supply hose. Then, wrap the threads of the 1/4” NPT Female hose connector with approximately 3” of Teflon tape. Next, connect the 1/4” NPT Female hose connector to the inlet side of the Mini Air Filter.

5. Attach a 1/4” NPT Male hose connector to one end of the outlet extension hose (to which you will connect a tool). Check to make sure the other end of the outlet extension hose is fitted with a quick coupler. Then, wrap the threads of the 1/4” NPT Male hose connector with approximately 3” of Teflon tape. Next, connect the 1/4” NPT Male hose connector to the outlet side of the Mini Air Filter.

6. Connect the quick coupler of the air outlet extension hose to the tool you are using. Turn on

the air compressor and regulate the desired PSI to the tool by pulling up and turning the Pressure Adjustment Knob (part #1) on the Mini Air Filter clockwise for reduced air pressure, or counterclockwise for increased air pressure. Press down on the knob to lock.

7. The Mini Air Filter is now ready for use. NOTE: Depending on usage, periodically examine the Drain Cup (part #11) for accumulated water that is being separated from the compressed air system. See Step one for instructions on draining the excess fluid from the Drain Cup.

SEE REVERSE SIDE OF THIS INSTRUCTION FLYER FOR PRODUCT WARNINGS, PRECAUTIONS, PARTS LIST, AND ASSEMBLY DIAGRAM.

CLEANING AND MAINTENANCE

1. When the water level rises to the bottom edge of the Filter Mesh Mounting (part #9) within the Drain Cup (part #11) it is necessary to remove the excess fluid. To drain the fluid slowly turn the Water Valve Drain (part #14) counterclockwise until the fluid begins to flow from the Drain Cup. When all of the fluid has been drained turn the Water Valve Drain clockwise to tighten.

2. To clean, wipe with a clean, damp cloth, using a mild soap with water if necessary. Then, dry.
