Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
Warnings WARNING WARNING EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury. • Do not operate the unit when fatigued or under the influence of drugs or alcohol. • Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals. • Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings.
Warnings Keep Components A and B Separate Cross-contamination can result in cured material in fluid lines which could cause serious injury or damage equipment. To prevent cross-contamination: • Never interchange component A and component B wetted parts. • Never use solvent on one side if it has been contaminated from the other side. Changing Materials NOTICE Changing the material types used in your equipment requires special attention to avoid equipment damage and downtime.

Overview Overview The left side of the mix manifold is intended for the major volume material, or the higher viscosity material if using a 1:1 volume mix. This side is referred to throughout the manual as the resin side or “A” side. The right side is referred to as the hardener side or “B” side. Follow these recommendations for setup (see FIG. 1 on page 6): • • See FIG. 2 to view flow of A and B material inside the XM PFP Mix Manifold.
Installation Installation Mounting The mix manifold is designed for use on proportioning pumps with independent drive motors. Do not use this manifold on a mechanically linked sprayer without using mechanically linked on/off A and B valves as this will result in fluid pressures that can rupture equipment and cause skin injection. To mount the bare manifold, drill four holes in the mounting surface, and secure with four 5/16-18 x 1/2 in. (50 mm long) screws.
Grounding Grounding The equipment must be grounded to reduce the risk of static sparking. Static sparking can cause fumes to ignite or explode. Grounding provides an escape wire for the electric current. • Pump: use a ground wire and clamp as instructed in your XM PFP sprayer operation manual. • Air and fluid hoses: use only electrically conductive hoses with a maximum of 500 ft (150 m) combined hose length to ensure grounding continuity. Check electrical resistance of hoses.
Operation Operation Pressure Relief Procedure 6. Disengage trigger lock. Follow the Pressure Relief Procedure whenever you see this symbol. This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment. ti19265a1 7.
Operation Flush 3. Close mix manifold inlet ball valves. The equipment must be grounded to reduce the risk of static sparking. Static sparking can cause fumes to ignite or explode. Grounding provides an escape wire for the electric current. If your system uses heaters, shut off the main power to the heaters and heated hose control and allow to cool before flushing. ti20129a NOTICE To prevent fluid from curing in the equipment, flush the system frequently.
Operation 8. Cycle the solvent flush ball valves on and off independently several times to be sure both sides are thoroughly flushed. Continue flushing until clean solvent dispenses. Dispensing and Spraying 1. Close solvent inlet valves. ti19269a 9. Turn off solvent pump air supply. 10. Hold the metal part of the gun firmly to a grounded metal pail with lid in place. Trigger gun until all fluid pressure is relieved. ti20095a 2. Open mix manifold inlet ball valves. 11. Engage trigger lock. 12.
Operation Volume Balancing the Mix Manifold Ratio errors can occur between the sprayer and the mix manifold even when the sprayer output ratio is accurate. The following can occur when the hoses are not volume balanced to the mix ratio: • • • Hoses fill to high pressure while metering on-ratio. Only the A material hose rises to spray pressure. Off-ratio at the mix point until hose pressures equalize. Hose Selection Hoses should be sized to match the hose volume ratio to the mix ratio.

Maintenance Maintenance Clean Static Mixers See FIG. 1, page 6. One 12 element mixer is attached (S, Part No. 262478) to the integrator hose (L). This housing uses mix elements, available in a package of 25 (W, Part No. 248927). NOTICE Never use a swivel union on the mixer inlets. The union will compress the tube and make it impossible to remove the mix element. Clean Mix Manifold Outlet 1. Remove outlet fitting (33) to expose B center injection tube (9). 9 33 ti20096a 2.
Troubleshooting Troubleshooting 1. Relieve the pressure before you check or service any system equipment. Problem Little or no resin output. 2. Check all possible causes and solutions in the troubleshooting chart before disassembling the manifold. Cause Solution Fluid inlet is plugged. Clean inlet; remove obstruction. See Clean Mix Manifold Outlet, page 15. Fluid container is empty. Refill. Little or no hardener output. Fluid inlet is plugged. Clean inlet; remove obstruction.
Repair Repair Follow Pressure Relief Procedure, page 10, when you stop spraying and before cleaning, checking, servicing, or transporting equipment. Read warnings in your sprayer manual. • • NOTICE Be sure to label all fluid parts A or B when disassembling them. Doing so prevents interchanging resin and hardener parts during reassembly, which will contaminate the materials and the fluid path through the equipment. Color-coded chemically resistant tape may be used to label the parts.
