Warnings 3A2988B 3 Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama- tion point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks.
Warnings 4 3A2988B 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.
Warnings 3A2988B 5 Keep Components A and B Separate Changing Materials 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.
Component Identification 6 3A2988B Component Identification Key: A A (Resin) Supply Inlet, 3/4 npt(m) B B (Hardener) Supply Inlet, 1/2 npt (m) C A (Resin) Ball Valve and Shutoff Handle D B (Hardener) .
Overview 3A2988B 7 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.
Installation 8 3A2988B Installation For assistance in setting up a plural component sprayer, contact your Graco distributor, to ensure that you select the proper type and size equipment for your system. Fluid Inlets See F IG . 1 on page 6. The A and B fluid inlets are equipped with 3/4 in.
Grounding 3A2988B 9 Grounding • Pump: use a ground wire and clamp as instructed in your XM PFP sprayer operation manual. • Air and fluid hoses: use only electrically conduc- tive hoses with a maximum of 500 ft (150 m) com- bined hose length to ensure grounding continuity.
Operation 10 3A2988B Operation Pressure Relief Procedure Follow the Pressure Relief Procedure whenever you see this symbol. Relieve A and B Fluid Pressure 1. Engage trigger lock. 2. Press Stop to turn sprayer OFF. 3. Close all air motor supply valves or any source of fluid pressure.
Operation 3A2988B 11 Flush NOTE: • Ensure the chosen flushing fluid is compatible with dispense fluid and the equipment wetted parts. • Solvent may channel through viscous fluids and leave a coating of mixed fluid on the inner tube of your hose. Be sure all fluid is thoroughly flushed from the hose after each use.
Operation 12 3A2988B 8. Cycle the solvent flush ball valves on and off inde- pendently several times to be sure both sides are thoroughly flushed. Continue flushing until clean sol- vent dispenses. 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.
Operation 3A2988B 13 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.
Operation 14 3A2988B Example #1: What is the pressure loss of a 2,000 cps material through 150 ft of 3/8 in. ID hose at 0.75 gpm? 690 psi (from chart) x 2 (2,000 cps /1,000) x 3 (150 ft / 3) x 0.75 (gpm) = 3105 psi loss This is a lot of pressure loss before reaching the spray gun.
Maintenance 3A2988B 15 Maintenance Clean Static Mixers See F IG . 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). Clean Mix Manifold Outlet 1.
Troubleshooting 16 3A2988B Troubleshooting 1. Relieve the pressure before you check or service any system equipment. 2. Check all possible causes and solutions in the trou- bleshooting chart before disassembling the mani- fold. Problem Cause Solution Little or no resin output.
Repair 3A2988B 17 Repair Check Valves When replacing material check valves or solvent check valves, reinstall with proper flow direction. Follow Pressure Relief Procedure , page 10, when you stop spraying and before cleaning, checking, ser- vicing, or transporting equipment.
