Operation

WARNING

Do not exceed the Maximum Incoming Air Pressure of the equipment. Over pressurizing can cause component rupture and serious injury.

Model 234401, Series D

1.Attach air hose(s) to air regulator outlet valve 289165.

2.Attach air hose to main shut-off valve 288798.

3.Open main shut-off valve 288798.

4.Turn the T-hand adjusting screw in or out to adjust regulator to desired setting.

5.Open outlet valve 289165 to supply air to spray guns or tool.

6.With air flowing, readjust air pressure regulator if necessary.

7.Turn off unit when not in use. Follow Pressure Relief Procedure, page 8.

Model 24M178, Series B

1.Attach air hose(s) to outlet elbow fitting 120375.

2.Attach air hose to inlet elbow fitting C19024.

3.Open main shut-off valve 288798.

4.Turn off unit when not in use. Follow Pressure Relief Procedure, page 8.

Automatic Drain

The automatic drain is equipped with a float actuated device which automatically ejects liquid contaminates under pressure.

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 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.
