Installation Bare Pumps Bare pumps are available for those installations which require a highly customized system. For a safe and efficient system, Graco recommends that the air and fluid components supplied with the Wall Mount and Cart Mount models also be used in customized systems. Refer to the Parts Drawings on pages 26–37 for part numbers. In addition, the accessories shown in the Typical Installation drawings and discussed in the following pages of this manual should be used.
Installation Air Control Accessories Automatic Pressure Relief Valves Install the accessories in the order shown in Fig. 4. Mount only the air regulator (E) and a master air valve (A) at the pump. Mount all other accessories on separate wall brackets to reduce stress on the pump inlet. Note that one air filter (B) can serve multiple pumps by using an air manifold downstream from the air filter.
Installation DD NOTE: If you mount the pump on a wall, turn the displacement pump inlet assemblies (CC) to face forward, rather than backwards as shown in Fig. 6. EE 37B Connect Fluid Supply Hoses RES For Two Displacement Pump Models HARD 1. Connect the resin supply hose (EE) to the 3/4 npt swivel inlet (37B) for the resin displacement pump. See Fig. 6. 37A 2. Connect the hardener supply hose (DD) to the 3/4 npt swivel inlet (37A) for the hardener displacement pump. See Fig. 6. CC 02889 Fig.
Installation – Optional Fluid Heaters All Models NOTE: For systems requiring one heater for each fluid, see page 38 to order the heaters and required plumbing (items 201 to 205). 201a 201b 201 202 204 OUT 1. Mount a heater to each side of the mounting bracket using the three screws (201a) and lockwashers (201b) supplied with each heater. See Fig. 8. 2. Connect a swivel union (202) to the outlet of each heater. See Fig. 8. IN 3. Connect a swivel union (203) to the inlet of each heater. See Fig. 8.

Installation – Optional Solvent Pump NOTE: The optional solvent pump is not offered as a kit; order parts as needed. The optional parts shown here are listed on page 39. These instructions assume that the pump is being mounted to the back of the stand offered in this manual. The Typical Installations on pages 8–9 show alternate installations. Adjust your installation according to your specific needs. 4. Couple the hose (303) and couplings (302). Connect the hose (303) to the adapter (301). 5.
Flushing When to Flush the System How to Operate the Mixer Manifold D Flush the system before its first use to remove the light oil which was left in after factory testing. To open or close the mixer manifold (N) fluid valves (LL) push the handle (KK) down to open and up to close. See Fig. 13. D Flush the manifold mixer (N), using the solvent pump, as frequently during the day as necessary to avoid exceeding the pot life limit of the material being pumped.
Flushing How to Flush the System WARNING If your system is equipped with heaters, always shut off the main power to the heaters before flushing. Circulate the fluid through the system for at least 10 minutes to cool the fluid and the heater. This reduces the risk of serious injury from burns. NOTE: For the first time flushing, we recommend using mineral spirits solvent (also called white spirit) to flush out the oil. Then flush again using a solvent that is compatible with the fluid you will be dispensing.
Operation Check the Drainage Bottles and Hoses WARNING WARNING Handling Plural Component Materials Be extremely cautious when handling plural component materials and solvents used with them. Some are extremely toxic. See the WARNING on the front cover. Read and follow the coating and solvent manufacturer’s safety precautions and warnings, including information regarding protective clothing, eyewear, and respirators.
Operation 6. Open the mixer manifold (N) and trigger the dispense valve (S). Startup WARNING 7. Set the air pressure to the feed pumps at 88 psi (0.6 MPa, 6 bar) or 25% of proportional pressure at the fluid outlets, whichever is less. Use the gauges (J1) to monitor this pressure. Higher pressures may prevent the proportioning pump inlet ball checks from setting properly.
Operation NOTE: Since this is a fixed ratio system, you typically do not have to check the mix ratio. 10. While observing the pump outlet gauges (J2), adjust the resin and hardener drain valves (P1,P2) until the gauges show your normal operating pressure. If the mixed fluid does not cure or harden properly, check the ratio of resin to hardener. NOTE: The pressure must be within 20% of the original spraying pressure to get a usable test. Checking the Mix Ratio 1.
Shutdown and Care of the System Pressure Relief Procedure WARNING INJECTION HAZARD The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid under high pressure can be injected through the skin and cause serious injury.
Troubleshooting WARNING WARNING To reduce the risk of serious bodily injury, always follow the Pressure Relief Procedure on page 21 whenever you shut off the pump, when checking or servicing any part of the dispensing system, when installing, cleaning or changing fluid tips, and whenever you stop dispensing. This chart uses the proportioner gauges to determine pump malfunctions. Faulty manifold check valves can mask pump cylinder problems. Always keep these valves operating properly.
Troubleshooting Problem System won’t run or stops while running. Solution Air pressure or volume too low. Increase, check air compressor. Closed or restricted air line or air valve. Open or clean as required. Fluid valves closed. Open fluid valves. Clogged fluid hose. Replace fluid hose. Air motor worn or damaged. Service air motor. See instructions in separate manual 306982. Displacement pump stuck. Service pump. See instructions in separate manual 307944 or 684004.
Service – Displacement Pump Removal and Replacement 33 Stop the pump at the bottom of its stroke. HARD RES Thoroughly flush the system with a solvent which is compatible to the fluid being pumped, then follow the Pressure Relief Procedure on page 21. The Flushing procedure is on page 17. CAUTION If you are changing to a different type of fluid, completely clean all of the equipment and hoses, making sure that no fluid remains in any part of the system. 125 308224 RES 24 HARD 2.
Service – Displacement Pump Disassembly 1. Remove the locknuts (113) from the top of the yoke (114) of the two outer displacement rods. See Fig. 22. Unscrew the outer locknuts (122) from the top of the tie plate (123) on the two displacement pumps. Use a screwdriver and hammer to loosen. NOTE: The tie rods (111) shown in Fig. 22 are removed from the tie plate (121) for clarity only and do not require removal. 2. Remove the two outer pumps from the tie plate.
