REACTIVE CHEMICALS HAZARD

Graco Inc. does not manufacture or supply any of the reactive chemical components that are used in this equipment, and is not responsible for their effects. Because of the vast number of chemicals that could be used, and their varying chemical reactions, the buyer and user of this equipment should determine all facts relating to the materials used, including any of the potential hazards involved. Particular inquiry and investigation should be made into potential dangers relating to toxic fumes, fires, explosions, reaction times, and exposure of human beings to the individual components or their resultant mixtures. Graco assumes no responsibility for loss, damage, expense, or claims for bodily injury or property damage, direct or consequential, arising from use of such chemical components.

Installation

Grounding

Proper grounding is an essential part of maintaining a safe system.

To reduce the risk of static sparking, ground the pump.

Check your local electrical code for detailed grounding instructions for your area and type of equipment. Be sure to ground all of this equipment:

1.

Pump: use a ground wire and clamp as instructed in your pump instruction manual.

2.

Fluid hoses: Use only grounded hoses with a maximum of 500 feet (150 m) combined hose length to ensure grounding continuity.

3.

Spray gun, manifold, or dispensing valve: obtain grounding through connection to a properly grounded connection to a properly grounded fluid hose and sprayer.

4.

Object being sprayed: according to local code.

5.

Supply Containers: according to local code.

6.

All solvent pails used when flushing, according to local code. Use only metal pails, which are conductive. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continuity.

7.

To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the gun firmly to the side of a grounded metal pail, then trigger the gun.

Installation

(See Fig. 1)

For assistance in setting up a plural component system, contact your Graco distributor. This will help assure that you select the proper type and size equipment for your job.

Use the spacer (40), screws (37), nuts (38) and lockwashers (39) provided to mount the manifold.

Connect the supply lines from your pump to the manifold inlets (R & Q). The solvent inlet (Q) is 1/4 npt(m).

The resin and hardener inlets (R) are 3/8 npt(m) in

Model 215626 (high volume) and 1/4 npt(m) in Model

215625 (low volume) manifold.

Connect your static mixer or hose to the manifold outlet (S). The high volume manifold has a 1/2 npt(m) outlet. The low volume manifold has a 1/4 npt(m) outlet.

Operation

Start-up

The mixer manifold was tested in oil, which was left in to protect the manifold. Before operating, thoroughly flush the manifold to prevent contamination of the fluids.

Be sure all fluid is thoroughly flushed from the hose after each use.

Disassemble all other dispensing equipment, as necessary, and clean thoroughly.

Flushing Procedure

Place the handle in the UP, or closed, position. Turn on the solvent supply pump. Open one of the solvent valves. Release the spray gun safety latch. Hold the gun firmly to the side of a grounded metal pail, then trigger the gun to flush. Flush until all contaminants and oil are removed. Release the trigger, engage the safety latch, and close the solvent valve. Repeat for the other solvent valve.

Any ratio check valves on the manifold output side must be flushed. Place a container under both valves to catch the waste solvent. Flush the valves after triggering the gun, one side at a time.

Solvent may channel through viscous fluids and leave a coating of mixed fluid on the inner tube of your hose.

Fig 2 shows the handle in the UP, or closed, position and the right solvent valve open with solvent flowing through the right fluid chamber and out through the mixing chamber.

Solvent

CAUTION

To prevent fluid from setting up in the dispensing equipment, flush the system frequently. Be sure there is adequate solvent in the solvent supply before starting to spray.

Dispensing

To dispense the resin and hardener, turn on the supply pumps. Then push the handle forward (DOWN) to the open position. To stop the flow, move the handle to the

UP or closed position.

Fig 3 shows the handle in the DOWN, or open, position, solvent valve closed, and resin and hardener flowing through the manifold.
