2.0 Installation The following instructions should be read carefully before installing the RotoClone. 2.1 Foundations Foundations must be true, level, and rigid enough to prevent vibration and support the weight of the RotoClone. (See Section 6, Table 2 for net weights of RotoClone.) 2.2 RotoClone Erection (Arrangement A) Refer to Installation Diagram - Figure 1. Assembly of the RotoClone should proceed in the following manner sealing all joints using gaskets and bolts included with shipment.
RotoClone Erection (Arrangement D) Refer to Arrangement D Erection Diagram - Figure 2. Assembly should proceed in the following manner, using gaskets and bolts included with shipment for each joint. Some RotoClones, sizes 16 and smaller, may have inlet, outlet, and expansion chamber welded to housing in lieu of flanged and bolted connections. 1. Place hopper section on foundation and anchor. 2. Bolt precleaner section to hopper top.
2.3 Duct Connections (Arrangement A) Inlet and discharge ducts must be supported from floor, wall, or ceiling, and not by the RotoClone. The joint between the RotoClone inlet and exhaust main must be water-tight. Inlet duct should slope downward with bottom of duct no lower than bottom of RotoClone inlet. There should be at least four (4) duct diameters of straight run leading to the inlet of the RotoClone or performance may be impaired.
Type W RotoClone Pressure Gage Pressure switch adjusted to 28-30 lbs. Opens contact on low pressure. Closes contact on high pressure. Solenoid Valve (furnished when specified) Strainer Figure 4 — Piping Diagram, Arrangements A and D 2.6A Pressure Switch A switch is supplied with the RotoClone which will stop the RotoClone motor automatically when water supply fails or water pressure falls below 28 psi.
2.12 Drive Type W RotoClones are belt-driven. Motor, if supplied by others, should be equipped with adjustable slide base. Short center V-belt drive, if provided by others, is the preferred arrangement. V-belt drives are usually mounted by the factory in an Arrangement 9 motor mounting. Where the motor mounting is Arrangement 1 or the motor and drive are too large to be shipped mounted on the unit, refer to belt manufacturer’s recommendations for belt tension, or call AAF for instructions.
4.5 RotoClone Impeller Inspect the RotoClone impeller periodically for accumulations of foreign material or obstructions in blade hooks. The blade hooks formed by the leaving edge of the impeller blades convey the collected dust and water out of the airstream. A build up of dust within these hooks may be sufficient to cause pronounced vibration or dust and water entrainment.

5.0 Troubleshooting 5.1 Water Entrainment - Excessive discharge of water in the exhaust may be due to the following: • Incorrect rotation (correct rotation is counter-clockwise, when viewed form the drive end). • Incorrect size cone spray or auxiliary nozzles and incorrect spray pattern (i.e. flat spray at 7 o’clock position viewed from the inlet and parallel to blades and cone spray to be centered at wheel). Inlet spray should just miss inlet perimeter as it passes into the scroll.

9.0 Supplements For Optional Features 9.1 Food Quality W RotoClones “Food Quality” refers to features on the W RotoClone that make it readily accessible for interior cleaning and exterior finishing to facilitate washdown by minimizing surfaces that can collect and trap material or water.
Type W RotoClone ® 9.2C Water Connection The “shipped loose” piping assembly is attached to the RotoClone at the two unions on the end of the loose piping and connecting pieces on the RotoClone. Connect the water supply line to the strainer on the other end of the RotoClone piping assembly. It is recommended that a manual shut off valve (supplied by others) be installed in the supply line to facilitate maintenance on the flow switches and solenoid valves.
