Connect the Solvent Flush Supply Line Remove the safety panels (38,39,40). See Fig. 4 onpage 10. Connect a grounded fluid hose (X) from thesolvent...

309024 9 Installation Grounding WARNING FIRE AND EXPLOSION HAZARD Before operating the pump, ground thesystem as explained below. Also readthe section FIRE AND EXPLOSION HAZARD on page 4. 1. Pump: use the ground wire and clamp (supplied). See Fig. 3. Loosen the grounding lug locknut (W)and washer (X...

10 309024 Ratio Adjustment Understanding the terms used with the Variable Ratio Hydra-Cat (VRHC) System, how it functions, and how to find and set the correct ratio(s) for your applica-tion, is the key to easier, more versatile operation ofyour proportioning system. Be sure to read and understand th...

309024 11 Determining the Ratio Determine your system conditions If these are your conditions – one primary pump, onesecondary pump, fluids are ready-to-spray viscosity –set the ratio as explained under Setting the Secondary Pump(s) on page 14. If these are your conditions – one primary pump andone ...

12 309024 Set the Ratio Fig. 5 shows the relationship between the primarypump and the secondary pump. To set the secondary pump on a standard VRHCSystem with only two pumps, refer to Setting the Secondary Pump(s) on page 14. To set the secondary pump on a non-standard VRHCSystem or for an additional...

309024 13 Calculate the Ratio Setting In this example, A 5:1 ratio of base to catalyst is required. The base/primary pump Model (e.g. 221074);effective area is 0.470 in. The catalyst/secondary pump Model (e.g. 221026);effective area is 0.278 in. 1. To determine the base to catalyst setting. a. Multi...

309024 15 Operation Pressure Relief Procedure WARNING SKIN INJECTION HAZARD The system pressure must be manuallyrelieved to prevent the system fromstarting or spraying/dispensing acciden- tally. Fluid under high pressure can be injectedthrough the skin and cause serious injury. Toreduce the risk of ...

16 309024 Operation The pumps, mixer manifold and other componentswere tested with lightweight oil at the factory. Beforeoperating the pump, thoroughly flush the VRHC toprevent contamination of the fluids. System Flushing NOTE: Flush the mixer, hose and gun/valve often enough to prevent fluid from r...

309024 17 Operation NOTE: To open the mixer manifold (120), put the handle in the down position. To close the mixermanifold, put the handle in the up position. See Fig. 7on page 16. Standard Operating Flushing 1. Use the solvent valves to flush contaminants andmixed fluids from the mixer manifold, h...

18 309024 Troubleshooting Troubleshooting Techniques Because the pumps are mechanically linked, the actionof one pump can affect the readings of the secondpump. Therefore, the key to successful troubleshootingis to be sure to isolate the problem. For example, the secondary pump pressure, as readon t...
