1/2 in. (13 mm) Nap Roller Cover

Contractor Inline Valve

3600 psi (24.8 MPa, 248 bar) Maximum Fluid Inlet Pressure *

* The best operating pressure is the lowest pressure that provides an even paint supply to the roller and typically does not exceed

300 psi (2.1 MPa, 21 bar).

CAUTION

Never leave water in the pump, inline valve, or roller frame.

Doing so could cause corrosion and damage from freezing.

Warnings and Cautions

WARNING

EQUIPMENT MISUSE HAZARD

Misuse can cause the equipment to rupture or malfunction and result in serious injury.

To help prevent injury

Do not modify the extension tube or roller frame or use parts not designed for this equipment.

Do not use 1,1,1–trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in this or any other pressurized aluminum equipment.

Such use could result in a chemical reaction, with the possibility of explosion.

INSTRUCTIONS

FIRE AND EXPLOSION HAZARD

Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and result in a fire or explosion and serious injury.

To help prevent injury from fire or explosion

Provide fresh air ventilation to avoid the buildup of flammable fumes from flushing fluids or the coating being applied.

Keep the application area free of debris, including solvent, rags, and gasoline.

FLUID INJECTION HAZARD

If high-pressure fluid pierces your skin, the injury might look like “just a cut”. But it is a serious wound. Get immediate medical attention.

To help prevent injection

Keep your hands and body away form the roller frame when flushing. High pressure fluid emitted from the holes in the frame could cause an injection injury.

Always relieve pressure before you check or repair leaks and when you turn off pump or stop painting.

Never use components rated less than system

Maximum Working Pressure.

ELECTROCUTION HAZARD

Failure to observe the electrical hazards described below could result in serious injury, including burns or electrocution.

To help prevent harmful electrical shock

Avoid contact with power lines.

Follow all grounding instructions in your separate pump instruction manual, and comply with all local, state, and national fire, electrical, and safety regulations.

Use only Graco paint hoses.

Installation

Assemble pressure roller as shown in Parts Drawing, page 4. Attach pressure roller assembly to inline valve.

When connecting EvenFlow roller frame to the

Contractor Inline Valve, use a wrench to tighten.

Pressure Relief Procedure

WARNING

psi/MPa/bar

To help prevent injection injuries, follow this procedure whenever you stop painting.

1 .

Put inline valve trigger safety in SAFETY ON position (Fig. 1).

2 .

Shut off power to pump.

3 .

Turn prime/spray valve to PRIME position to relieve pressure in system.

4 .

Put inline valve trigger safety in SAFETY OFF position, and trigger inline valve to relieve any pressure in hose.

5 .

Put inline valve trigger safety in SAFETY ON position, and keep pump prime/spray valve in

PRIME position until you paint again.

Operation

WARNING

INJECTION HAZARD

To reduce the risk of a fluid injection injury, do not operate the inline valve with the tip guard or trigger guard removed.

In-Line Valve Trigger Safety Lever

For SAFETY ON position, rotate trigger safety lever so it is in line with trigger. For SAFETY OFF position, flip safety lever so it is 90 to trigger. Fig. 1.

NOTE: In the SAFETY ON position the lever sits in a detent which holds it in place.

Fig. 1

SAFETY ON SAFETY OFF

Startup

NOTE:

The Contractor Inline Valve can be used as an airless spray gun by attaching a Handtite Guard and RAC5 Switchtip.

2 309445

1 .

Follow pump priming instructions using lowest pressure setting at which pump primes.

2 .

Turn prime/spray valve to SPRAY position.

3 .

Disengage inline valve safety latch, trigger the inline valve, and roll the surface until paint comes to roller.

NOTE: Trigger the inline valve briefly only when you need more paint. Determine how often you must trigger the inline valve to maintain an even paint supply to the roller.

4 .

Increase pump pressure only if triggering inline valve cannot supply enough paint for your rolling speed.

5 .

Relieve pressure , page 2, whenever you stop painting.

Elevate roller end of extension tube to prevent paint from draining out.

Flush pump, inline valve, and roller frame immediately after each use to prevent paint from drying in roller frame and damaging it.

Cleaning

NOTE: Follow this procedure to flush the roller frame and inline valve. The pump you are using may have additional flushing steps, such as cleaning filters and screens. See the pump flushing instructions.

Leave the roller frame attached to the inline valve for this procedure.

Cleaning the EvenFlow Roller Frame

1 .

Relieve pressure , page 2.

2 .

Remove roller cover (19) and diffuser (23) from roller frame as follows (see Parts Drawing ): a.

Using your thumb, press down on clip (5) to release end caps (2 &4), diffuser (23) and roller cover (19) into a pail.

b.

Remove roller cover (19) from diffuser (23).

c.

Pull end caps (2 & 4) off diffuser (23).

3 .

Clean roller cover (19), caps (2 & 4) and diffuser

(19) with water or a compatible fluid for oil–based materials.

4 .

Place roller frame (1) in paint pail. Be sure the holes in roller frame (1) are facing inside the paint pail.

5 .

Prime pump with water or flushing fluid for oil–based materials. Use the lowest pump priming pressure setting.

6 .

Turn prime/spray valve to SPRAY.

NOTE: Perform Step 7 at the lowest pressure possible.

7 .

Trigger inline valve until flushing fluid begins to dilute the paint.

8 .

Place roller frame (1) in another bucket and continue flushing until fluid coming out of the roller frame (1) is clear.

Cleaning Contractor Inline Valve

1 .

Relieve pressure , page 2.

2 .

Push up on bottom of trigger guard and swing it away from trigger.

3 .

Unscrew inline valve handle from housing.

Remove filter and clean it in compatible solvent.

NOTE: Do not soak entire inline valve in solvent.

Prolonged exposure to solvent can ruin packings.

4 .

Apply lithium–based grease to threads of inline valve handle and reassemble inline valve.

Storage

If you are going to store the airless equipment for an extended period of time after flushing with water-base fluid, flush again with Graco Pump Armor or mineral spirits/paint thinner. Leave this fluid in the system during storage.
