Upper arm nozzles point downward, and lower arm nozzles point upward. Arms in the prewash chamber each have two tubes (the slightly longer arm goes below). The arms with five tubes fit in the upper brackets, and the arms with four tubes fit in the lower brackets. To install arms, slide manifolds on the guides toward the rear of the machine (Fig. 26). Then latch arms in place (Fig. 27). Fig. 25 Fig. 26 Fig. 27 Replace the pump intake screens, strainer pans, and strainer baskets. Rehang the curtains (refer to pages 11 – 14). Leave the machine doors open to allow the interior to air out and dry. Clean machine exterior like any other stainless steel appliance. Use damp cloth and mild soapy water. Flush the openings where the sensors are located at the load end of the machine (Fig. 28). Do not attempt to clean these openings with any metallic object as damage to sensors can occur. CLEAN SENSOR OPENINGS AT LOAD END OF MACHINE Fig. 28 – 8 – CLEANING THE TOP DUCT Disconnect electrical power supply(ies) and follow lockout / tagout procedures before you begin cleaning. Debris and airborne particles will settle on the Top Covers and the surfaces inside the Top Duct. The Top Duct should be cleaned about every two weeks, as appropriate for your location. There are two handles on each of the removable Top Covers so they can be lifted or moved to access the inside of the Top Duct for cleaning (Fig. 29). Before draining and cleaning the machine, perform the following cleaning task. Use an appropriate ladder and both hands to remove each Top Cover. Clean inside the Top Duct with mild detergent / warm water solution and brush, cloth, or sponge. Clean the Top Duct from the UNLOADENDof the machine towards the LOADEND. If necessary, the Top Duct may be hosed down. Rinse with clean water. Clean both sides of the Top Covers individually while they are removed. After cleaning the Top Duct and the Top Covers, replace each Top Cover in its correct location. After cleaning the Top Duct, clean the dishwasher as discussed on pages 7 – 8.
