2 FEATURES All recirculation pumps, valves, piping, and other components that come in contact with recirculated solutions are constructed of stainless steel. Removable spray headers have quick-disconnect couplings and O-rings for removal without tools. Jet systems for Pre-wash, Wash, and Recirculated Rinse sections have machined jets fitted into headers. The jets are placed so that water bottles in baskets can be processed through the washer. The washer includes temperature guarantee for both recirculation tanks. The conveyor belt temporarily stops if recirculated solution temperatures drop below the set temperature, and restarts only when the solution reaches the proper temperature. Stainless-steel flat wire conveyor belt includes a safety overload clutch to prevent the belt from damaging the items being washed. Stainless-steel drawer-type solution strainer screens in the Pre-wash, Wash, and Recirculated Rinse sections are easily accessible and have perforations smaller than the machined jet orifices to filter the solutions and prevent the spray jets from clogging. The hydraulic hold-down system feed lines contain throttle valves to hydraulically hold down light plastic cages and steel pans on the conveyor belt. The control system monitors and automatically controls all process operations and functions. The control can keep up to 12 processing cycles in memory, programmed and named according to customer preferences. Cycle phase times, temperatures, and other key process parameters are programmable. Once a cycle is started, the programmed cycle values are locked in and cannot be changed until the cycle is complete. A second control column is provided on the non-operating/unload end. An RS-232 communication port is available to download process data to an external computer or printer. The integral thermal printer with automatic paper take-up provides a record of all cycle programs and inprocess performance data. Automatic self-cleaning screen for the Wash section treatment pump discharge is 3-1/2" (89 mm) diameter x 18" (457 mm) long, with 1/16" (1.6 mm) diameter perforations. Motorized ball valves direct the solution flow to either the jet system or the drain. Conveyor stop proximity sensor and a gate are provided at the end of the discharge conveyor to stop the conveyor drive when an item (pan, bottle basket, or cage) reaches the end of the conveyor. Automatic tank dump valves are provided to automatically open and drain each recirculation tank. Function is selectable through the main control. Automatic drain discharge cool down system uses a cold-water injection system to automatically cool effluent from the Pre-Wash section. A cold water system mounted in-line to the drain line cools spent recirculated treatments when draining treatment tank(s). The system is controlled by the automatic solenoid valve which opens when the tank drain valves are opened. Automatic alkaline detergent injection system provides automatic conductivity monitoring and direct injection of alkaline detergent into the wash tank. This system includes a liquid detergent injection pump, detergent pickup tube, 50' (15.24 m) of tubing, conductivity controller, and conductivity probe. Automatic acid detergent injection system provides automatic conductivity monitoring and direct injection of acid detergent into the wash tank. This system includes a liquid detergent injection pump, detergent pickup tube, 50' (15.24 m) of tubing, conductivity controller, and conductivity probe. Automatic neutralizer injection system provides direct injection of neutralizer into the wash tank each time the washer drains. This system includes a liquid detergent injection pump, detergent pickup tube, and 50' (15.24 m) of tubing. Bedding dispenser controls (a bypass proximity switch and conveyor motor control) are provided for use with the Basil 3600 Series Bedding Dispenser (see SD533). Power supply to the bedding dispenser is not provided by STERIS. SAFETY FEATURE The washer load end has a drive system EMERGENCY STOP button, and controls for the adjustable speed drive motor. The unload end has a drive system EMERGENCY STOP button and a secondary control column. CYCLE DESCRIPTION The Basil 6000 Series Tunnel Cage Washer features 12 programmable cycles. Each cycle can be programmed with the following phases: Pre-Wash. Water is diverted from the recirculated rinse tank, under pump pressure, to the pre-wash jet system. The water recirculates through the jet system and removes gross debris. On completion, the pre-wash water is drained. Wash. Hot detergent solution recirculates through the wash jet system under pump pressure. Temperature is adjustable to 190 F (87 C). The detergent solution remains in the wash tank to be used for subsequent loads. Recirculated Rinse. Hot water recirculates through the rinse jet system under pump pressure. Temperature is adjustable to 190 F (87 C). The rinse water remains in the recirculated rinse tank to be used for subsequent loads. Final Rinse. Hot water from building supply is heated through a steam heat exchanger and sprayed through the final rinse jet system. Spent solution flows to the recirculated rinse tank. Temperature is manually adjustable to 195 F (90 C). 2

3 OPTIONAL FEATURES Six-foot (1.83 m) long dryer section. A Dry phase can be programmed to start after the Final Rinse phase with this option. During the Dry phase, most of the water is removed by an air knife blow-off system (1.5 HP, 800 cfm [23 m 3 /min]). Hot air is recirculated throughout the chamber to help dry items. An insulated, stainless-steel, hotair type 6.0' (1.83 m) long dryer with single-blower system includes one steam-heated radiator, a plenum system, and a 5-HP air blower capable of 1600 CFM (45.30 m 3 /min.) air flow under recirculation at 210 F (99 C). Air ducting is stainless steel with dampers, as required. The dryer interior design allows complete draining. The conveyor belt is continuous through the washer and dryer sections. Discharge roller conveyor 4.0' (1.22 m) long. The conveyor for the discharge/unload end is available with 2.0" (51 mm) diameter, LPVC and PVC rollers, stainless-steel conveyor supports, and legs. Rollers have 3.0" (76 mm) end-collars and corrosion-free bearings and shafts. A stainless-steel drain pan with 2.0" (51 mm) drain connection is installed under the entire length of the discharge conveyor. ph neutralization and detergent monitoring system. This option monitors and controls the solution ph level of the drain discharge each time the washer drains and the concentration of detergent being used when the washer is processing a cycle. If necessary, the proper neutralizing agent is injected and the solution is recirculated and tested again. If the process fails after nine tries, an alarm sounds to indicate a problem with the system. The system includes all controls, conductivity and ph probes. Low pressure steam piping. This option allows the washer to accommodate psig ( kpa) dynamic steam pressure. Three-foot unload section. This option extends the unload end of the washer by 3.0' (0.91 m) to allow the operator to remove items before they enter a Basil 3600 Series Bedding Dispenser (see SD533). Seismic tie-down. The washer can be built to Seismic Zones 3 and 4 requirements. Garbel station, integrated. A bedding disposal unit is integrated on the load side of the conveyor. Used bedding is mixed with cold water, going through a hammer mill pulverizer before being sent to the drain.
