Installation

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 unit as close as possible to the equipment it serves.

3.

Install a main air shut-off valve upstream from the air controls to isolate them 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

Operation

WARNING

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

Auto Drain

When the bowl is pressurized, the piston travels down against the spring and closes the drain opening. When the bowl is depressurized (i.e., overnight when system is shut down), the spring lifts the piston from the seal, allowing the bowl to drain.

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.

You can push the piston stem on the bottom of the bowl to manually drain it.

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.

Maintenance

Maintenance

Coalescers with Auto Drain

• Relieve the pressure before cleaning, checking or repairing equipment. Follow

Pressure

Relief Procedure , page 4.

• Check system at least once per shift to ensure proper drainage.

• To maintain maximum filtering efficiency and avoid excessive pressure drop, filters must be kept clean.

Air Filters with Auto Drain

Cleaning

You do not need to remove the complete filter from the line to clean it.

1.

Follow the

Pressure Relief Procedure , page 4.

2.

Clean all parts with cleaning solvent and blow out filter body.

3.

Wash filter element in cleaning solvent. Blow the filter out from the inside.

It is recommended that Air Filter 234402 be installed upstream of the coalescing filter to remove 5 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.

Cleaning

You do not need to remove the complete coalescer from the line to clean it.

1.

Follow the Pressure Relief Procedure , page 4. Be

sure to shut off the air supply and depressurize the filter.

2.

Clean all parts with cleaning solvent and blow out coalescer body.

3.

Replace coalescer element.
