WARNINGS, PRECAUTIONS, PARTS LIST, AND ASSEMBLY DIAGRAM.

1. For ease of use, and to avoid damage to the Mini Air Filter, it is recommended that the unit be

mounted in a convenient location on the workbench or in the work area. This can be done by

attaching the Mounting Bracket (part #22) to the side of the workbench or wall, using two

wood or metal screws (not provided).

(Figure A)

2. Once the Mounting Bracket has been attached to a desired location, unscrew and remove the

Retaining Ring (part #23) from the top of the Mini Air Filter.

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.

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.
