Installation
1. Before installing air line components, blow out the pipe line to remove debris. Be sure air to the regula­tor is clean. Erratic operation or loss of regulation is usually caused by dirt in the regulator.
2. Install the Air Drying System as close as possible to the equipment it serves.

Shop Air Piping Layout

3. Install air shut-off valve 288798 upstream from the air system to isolate it for service.
4. Install system so air flows through filters in the direc­tion noted on top of filter.
5. A minimum 1/2” npt piping is recommended. Avoid using too many fittings, couplings, etc., which will restrict air flow.

Operation
WARNING
Do not exceed the Maximum Incoming Air Pressure of the equipment. Over pressurizing can cause compo­nent rupture and serious injury.
pressure drop across the element reaches 10-12 psi (69-83 kPa, 0.7-0.8 bar), the red indicator will be in full view, and the element should be replaced. Failure to replace the element when the pressure drop exceeds 10 psi (69 kPa, 0.7 bar) will affect your air quality and tool efficiency.
1. Attach air hose(s) to air regulator outlet valve
289165.
2. Open main shut-off valve 288798.
3. Turn the T-hand adjusting screw in or out to adjust regulator to desired setting.
4. Open outlet valve 289165 to supply air to spray guns or tool.
5. With air flowing, readjust air pressure regulator if necessary.
6. Turn off unit when not in use. Follow Pressure
Relief Procedure, page 5.
Coalescer Pressure Drop Indicator
The differential pressure drop indicator provides early detection of a clogged coalescing filter element. As the filter element becomes clogged, the red indicator starts to rise while air is flowing through the unit. When the
Automatic Drain
The automatic drain is equipped with a float actuated device which automatically ejects liquid contaminates under pressure.

Pressure Relief Procedure

WARNING
To avoid injury, relieve air and fluid pressure before checking, cleaning, or repairing the equipment.
The following is a basic pressure relief procedure. Be sure to follow the specific pressure relief procedure in your spray gun and/or fluid supply equipment manuals.
1. Close the main air shut-off valve.
2. Trigger the gun or dispense valve and open any drain valves to relieve pressure.

Maintenance

Relieve the pressure before cleaning, checking
or repairing equipment. Follow Pressure Relief Procedure, above.
Check system at least once per shift to ensure proper drainage.
Air Filter with Auto Drain 234402, Series B
To maintain maximum filtering efficiency and avoid excessive pressure drop, the filter must be kept clean. See Manual 309919 for cleaning and parts information.
Coalescer with Auto Drain 234397, Series B
It is recommended that Air Filter 234402 be installed upstream of the coalescing filter to remove 3 micron and larger size particles and sep­arate large droplets of moisture from the air line.
CAUTION
Never let the liquid level in the bowl reach the base of the coalescing element.
See Manual 309919 for operation, cleaning, and parts information.
Air Regulator 234394
Be sure air to the regulator is clean. Erratic operation or loss of regulation is usually caused by dirt in the regula­tor. See Manual 309924 for cleaning and parts informa­tion.
