Installation4. Fill the Colorant Tank and Primethe Color Injector (Optional)a. Reduce the air pressure supplied to the ColorantTank by turning the regulator on top of thetank in a counter-clockwise direction. Continueto turn the regulator until the Tank Pressuregauge indicates 0 psi.b. Lift the pressure relief ring at the top of the tankbefore removing four screws or unscrewing theclamps that hold the Tank Cover in place.i. Adjust the Colorant Tank Regulator to thedesired pressure. For 2000 centipoise colorant,50 psi (345 kPa, 3.4 bar) should be sufficient.To avoid machine damage and serious injury, do notallow the colorant tank pressure to exceed 110 psi(0.8 MPa, 8 bar).j. Attach the color line to the color injector usingthe quick disconnect. The disconnect has checkmechanisms on both sides to prevent colorantfor pouring out when not attached.c. Lift the cover off and lubricate or glue (usingRTV) the o-ring located in the groove on the bottomof the cover.d. Lift the colorant platen out of the tank if it isinstalled. In some applications it might not beused. (See Platen - Colorant Tank (Optional),page 9).k. Press and turn the manual actuator on the colorinjector solenoid to move the piston inside theinjector to the inject position. Any air bubblesthat may be trapped inside the color injector tothe bleed port will be forced out.e. Stir the pigment to the manufacturer requirements.f. Pour or scoop the colorant into the ColorantTank, filling it to the desired level. When fillingthe tank, leave room for the platen if being used.g. Place the platen, if needed, on top of the colorantwith the head of the screw facing up.h. Place the Colorant Tank Cover back on the tank.Be sure to seat the o-ring into the groove beforetightening the screws or clamps.l. Place a clear, 1/4 x 12 in. (0.6 x 31 cm) tubeover the bleed valve to allow a visual of thepurging process.m. Open the bleed valve and purge any air from theinjector when the color injector bleed valve is26 <strong>332312A</strong>
Installationfacing sideways or even slightly up to remove allthe trapped air.Bleed Valvee. Load the new pail into the machine, paying specialattention to put the “A” material on the “A”side.NOTICETo avoid cavitation and component interference, installthe pail on the pail shelf so that the handle of the pailwill not interfere with the ram during normal machineoperation.NOTE: Apply lubricant to the platen seal to aid theinstallation. Use material if a lubricant is not available.n. Close the bleed valve when it appears that all ofthe air has been purged.f. Open the Bleed Ball Valve on the platen hub toallow air to escape.o. Unlock the manual actuator on the color injectorsolenoid to return the injector to the properstate.NOTICEFailure to unlock the manual actuator will cause theinjector not to refill and color will not be dispensed.p. Cycle the injector.5. Load Material Pailsa. If a pail is not installed, proceed to the next step.If a pail is installed, refer to Pail Change-Over,page 34.b. Lower the pail shelf to its minimum height byturning the Ram Control Valve to the DOWNposition and applying downward pressure onthe pail shelf.c. Wipe the bottom of the platen with a clean ragto remove any foreign objects that might contaminatethe mixture.d. Remove the covers of both pails, paying closeattention not to drop dirt or other foreign objectsinto the new silicone. If the material did not settle,flatten the material out to ensure properpurging will occur.g. Set the Ram Air Regulator to 5 psi (35 kPa,0.3 bar).h. Turn the Ram Control Valve to the UP positionto raise the Pail Shelf to the platen.i. Slowly increase the Ram Air Regulator to theoperating pressure.NOTE: If your pails have liners, use special care not topush them down into the pail with the platen.NOTICETo avoid cavitation and machine damage, the RamControl Valve should be left in the UP position whilepumping.NOTE: Once the platen enters the pail, air shouldexhaust out of the Bleed Ball Valve.j. Allow enough material to escape to ensure all ofthe air is forced out from under the platen.<strong>332312A</strong> 27
