Motor Guard AC-6500 Instructions

The Motor Guard AC-6500 Air Control Unit removes moisture and particulates from compressed and provides a finely regulated supply for air for critical
applications. Its compact design and large airflow capacity make it a highly effective and economical addition to any compressed air system.
Before installing unit, relieve upstream pressure completely. Install unit in main air supply line with at least 20 feet of supply line between unit and
compressor. Failure to maintain this distance will cause excessive water vapor to pass through unit. Unit is designed for installation in a 1/2" line; use
appropriate fittings for installation in other line sizes. Apply pipe thread compound to male thread connections. Install unit level and in direction of
airflow as noted. Unit should be mounted to a rigid structure. A shut-off valve (1, not supplied) should be installed in the supply line near the inlet to
provide a positive pressure shut off for servicing of the unit.
WARNING: This product is intended for use in industrial compressed air systems only. Do not install where pressures or temperatures can
exceed those listed above.
Assemble unit as shown, connecting regulator/gauge/shut-off valve assembly (2) to outlet port on front or side of unit. Remaining port may be plugged
or used as a full pressure supply port. Apply thread sealing compound to fittings prior to assembly. Tighten fittings to a leak proof seal but to not over-
tighten. Mount unit vertically with supply line connecting to port marked "Air In" on top of filter. Before pressurizing, be sure bowls are turned fully
clockwise. Pressurize slowly to avoid high-pressure surge. Check for leaks.
To operate regulator, rotate t-handle (2) clockwise to increase supply pressure and counter-clockwise to decrease supply pressure.
Rotate handle on outlet valve (3) to a position parallel to flow to open valve.
Drain bowl of accumulated liquid daily or at the start of each shift by turning the drain cock (4) on the bottom of the unit counterclockwise.
Inspect daily for leaks.
