Granulators are normally shipped completely assembled unless the size of the machine or an agreement for special shipping arrangements prompts partial assembly. If inspection after shipment has revealed no shipping damage, unpack the unit by removing the polyethylene protective covering and banding. Remove the envelope with the parts list, assembly drawings, electrical schematics, and manual from the base evacuation area. You can now have the machine lifted from the skid. A forklift is ideal for the purpose, but take care to properly position the forks between the casters and the centrally mounted evacuation pipe from the side of the machine. ! CAUTION ! Do not attempt to lift the granulator by means of any shaft or protruding member, ESPECIALLY THE HOPPER Page 17 Installation 3-1 Scope This chapter contains all instructions required for experienced installation personnel to install the granulator and prepare it for production. You must follow all instructions carefully and in the sequence presented. Be sure to observe all DANGER, WARNING, CAUTION, and NOTE statements to prevent personal injury or machine damage. These statements are designed to make installation procedures safe and easy. 3-2 General Set-Up 1. Make certain the floor is clean, level, and free of obstructions before placing the machine into position. 2. Visually inspect the hopper infeed opening to ensure that no stray packing material or debris is present. 3-3 Inspecting and Cleaning Granulator Components ! CAUTION ! The cutting chamber combs are EXTREMELY SHARP. Always wear heavy glovesand exercise care when working in the cutting chamber. 1. Open the front base door and the hopper access door by unlatching the two (2) latches and swinging the doors into their open positions. Carefully inspect the interior of the hopper and above the rotor for foreign material or debris. Slowly and carefully turn the rotor by hand to verify that it rotates freely and without obstruction. Make sure that the rotor does not make any contact with the bed combs. Wipe the inside of the hopper and cutting chamber clean. With the hopper door opened, the cutting chamber safety switch located in the base of the machine will automatically disengage the switch body from the main switch assembly in the base. 2. Ensure that nothing has been left inside the machine. Page 18 3. Look inside the base evacuation area. Spare parts, such as combs, are often placed inside this area for shipping purposes. ! CAUTION ! The cutting chamber combs are EXTREMELY SHARP. Always wear heavy glovesand exercise care when working in the cutting chamber. 4. Carefully inspect the interior of the cutting chamber and evacuation area for foreign material or debris. 5. Noting the location of each segmented chamber, lower and remove them from the cutting chamber by loosening the handknob on each. Lift the rear of each segmented chamber off of the rear support bar to aid removal. Carefully inspect the interior of each segmented chamber for material or debris. See Figure 5. 6. Wipe all interior surfaces clean. 7. Place the three (3) segmented chambers back into their original position and tighten each handknob securely. 8. Verify that no material has been left inside the machine 9. Close the front base door and the hopper access door and secure the latches. ! CAUTION ! Do not run granulator until upper machine assembly is fully latched down. 3-4 Completing the Installation of Your Granulator 1. Open the drive guard by removing the bolts that attach the guard cover to the timing belt backing plate. 2. Check the timing belt for proper tension and alignment. 3. Upon completion, close the guard by placing the cover back into position, insert all the bolts originally removed, and tighten them fully. Page 19 4. Position and connect any optional accessory equipment such as vacuum lines, conveyors, and separators. Ensure all tubing joints are securely clamped and supported. 3-5 Electrical Considerations !!! DANGER !!! Improper electrical connections can damage the granulator and CAUSE SERIOUS OPERATOR INJURY OR DEATH! EX Series Screenless Granulators are designed for three-phase voltage operation. Refer to the unit nameplate or ID plate for proper voltage and amperage requirements. NOTE: Make sure to provide a correctly-sized and protected supply of electrical power to the unit. Maintain a safe ground and disconnect the power supply before servicing the unit. A qualified electrician should make electrical connections, and disconnect and lock out electrical power following OHSA 29CFR 1910.147. Check serial tag voltage/amperage requirements and make sure your electrical service conforms before making any electrical connections. Full load amps for EX Series Granulators are listed on the nameplate or ID plate. Make sure that all three phases are wired correctly. Bring properly sized power leads and grounds from a fused disconnect to the unit. Provide external overcurrent protection to the unit, using circuit brea...
