Isocyanate Hazard

Spraying materials containing isocyanates creates potentially harmful mists, vapors, and atomized particulates.

Read material manufacturer’s warnings and material MSDS to know specific hazards and precautions related to isocyanates.

Prevent inhalation of isocyanate mists, vapors, and atomized particulates by providing sufficient ventilation in the work area. If sufficient ventilation is not available, a supplied-air respirator is required for e v eryone in the work area.

Isocyanate Hazard

To prevent exposing ISO to moisture:

• Always use a sealed container with a desiccant dryer in the vent, or a nitrogen atmosphere. Never store ISO in an open container.

• Use moisture-proof hoses specifically designed for ISO, such as those supplied with your system.

• Never use reclaimed solvents, which may contain moisture. Always keep solvent containers closed when not in use.

• Nev er use solvent on one side if it has been contaminated from the other side.

• Always lubricate threaded parts with Part 217374 ISO pump oil or grease when reassembling.

To prevent contact with isocyanates, appropriate personal protective equipment, including chemically impermeable gloves, boots, aprons, and goggles, is also required for everyone in the work area.

Moisture Sensitivity of Isocyanates

Isocyanates (ISO) are catalysts used in two component foam and polyurea coatings. ISO will react with moisture (such as humidity) to form small, hard, abrasive crystals, which become suspended in the fluid. Eventually a film will form on the surface and the ISO will begin to gel, increasing in viscosity. If used, this partially cured ISO will reduce performance and the life of all wetted parts.

The amount of film formation and rate of crystallization varies depending on the blend of ISO, the humidity, and the temperature.

312766P 5

Isocyanate Hazard

Foam Self-Ignition

Some materials may become self-igniting if applied too thick. Read material manufacturer’s warnings and material MSDS.

Keep Components A and B Separate

CAUTION

To prevent cross-contamination of the equipment’s wetted parts, never interchange component A and component B.

Changing Materials

• When changing materials, flush the equipment multiple times to ensure it is thoroughly clean.

• Check with your material manufacturer for chemical compatibility.

• Some materials use catalyst on the A side, but some applications may use catalyst on the B side.

• Epoxies often have amines on the B (catalyst) side. P olyurethanes often have amines on the B (resin) side.

Installation

A bleed-type master air valve (AD) and a fluid drain valve (AE) are required in your system, to help reduce the risk of serious injury, including splashing fluid in the eyes or on the skin, and injury from moving parts when you are adjusting or repairing the pump.

A bleed-type master air valve (AD) is required in your system to relieve air trapped between it and the air motor when the valve is closed (see the WARNING on left). Be sure the bleed valv e is easily accessible from the pump , and is located downstream from the air regulator.

An air line filter (AC) to remove harmful dirt and moisture from the compressed air supply.

The bleed-type master air valve (AD) relieves air trapped between this valve and the pump after the pump is shut off. Trapped air can cause the pump to cycle unexpectedly and result in serious injury, including amputation. Install the valve close to the pump.

The fluid drain valve (AE) helps relieve pressure in the displacement pump, hose, and dispensing valve when shutting off the pump. Actuating the dispensing valve to relieve pressure may not be sufficient, especially if there is a clog in the hose or the dispensing valve.

System Accessories

Refer to FIG. 3 and the Accessories on page

24. To ensure maximum pump perfor-

mance, be sure that all accessories used are properly sized to meet your system’s requirements.

A second bleed-type air valve (AD) isolates the air line accessories for servicing. Locate upstream from all other air line accessories.

Fluid Line Accessories

A fluid drain valve (AE) is required in your

system to reliev e fluid pressure in the hose and gun (see the WARNING on left). Install the drain valve so that it points down and the handle points up when the valve is opened.

Air Line Accessories

Install the following accessories in the order

shown in the Typical Installation for Lubrica- tion Applications, using adapters as necessary:

An air line lubricator (AB) provides automatic air motor lubrication.

Operation

Pressure Relief Procedure

Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts.

1. Shut off the air to the pump.

2. Close the bleed-type master air valve (AD).

3. Hold a metal part of the dispense valve firmly to a grounded metal pail. Trigger the valve to relieve pressure.

4. Open all fluid drain valves in the system, having a waste container ready to catch drainage. Leave drain valve(s) open until you are ready to dispense again.

5. If you suspect the nozzle or hose is clogged or that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen the hose end coupling to relieve pressure g radually, then loosen completely. Clear hose or nozzle obstruction.

Flushing

• Flush at the lo west pressure possible. Chec k connectors f or leaks and tighten as necessary.

• Flush with a fluid that is compatible with the fluid being dispensed and the equipment wetted parts.

Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts.

1. Follow Pressure Relief Procedure, page

13.

2. Place suction tube in grounded metal drum containing cleaning fluid.

3. Set pump to lowest possible fluid pressure, and start pump.

4. Hold a metal part of the dispense valve firmly to a grounded metal pail. Trigger the dispense valve until clean solvent dispenses.

Flush Pump Before Use

The pump is tested with lightweight oil, which is left in to protect the pump parts. To prevent contamination of the fluid you are pumping, flush the pump with a compatible solvent before using it. See Flushing, page 13.

312766P 13

5. Remove valve from hose.

6. Follow Pressure Relief Procedure, and remove fluid filter and soak in solvent. Replace filter cap.

7. Cycle the pump slowly for at least 5 minutes, then stop and disconnect the air hose.

8. Push up on the ball (5) of the intake valve (29) to drain the lower part of the pump.

9. Turn the pump over to drain the upper part of the pump.

Operation

Daily Startup

1. Verify that the air needle valve (54) is closed.

2. Connect the air line quick disconnect coupler (55) to the transfer pump.

3. Turn on the main air supply.

4. Slowly open the air needle valve until the transfer pump runs slowly.

5. Use the air needle valve to control the pump speed.

Caution

Never allo w the pump to run dry. A dry pump will quickly accelerate to a high speed and can damage the pump. If the pump accelerates quickly or starts running too fast, stop it immediately and check the fluid supply. If the supply container is empty or air has been pumped into the lines, refill the container; prime the pump and the lines with fluid, or flush and leave it filled with a compatible solvent. Be sure to eliminate all air from the fluid system.

Corrosion Protection for Pump

Caution

Water or moist air can cause your pump to corrode. To help prevent corrosion, NEVER leave the pump filled with water or air. After normal flushing, flush the pump again with mineral spirits solvent (also called white spirit) or oil-based solvent, relieve pressure, and leave the mineral spirits solvent (also called white spirit) in the pump. Be sure to follow to the Pressure Relief Procedure on page 13.

Lubrication

If you are not using an accessory air line lubricator, manually lubricate the motor daily. Disconnect the air regulator, place about 15 drops of light machine oil in the pump air inlet, reconnect the regulator and turn on the air supply to dispense oil into the motor.

Do not attempt to operate pump unless it is securely mounted in a drum.

Daily Shutdown

1. Disconnect the air line quick disconnect coupler (55).
