1 Castle Model 233HC Vacuum and Gravity Steam Sterilizer for Healthcare Applications data and specifications PRODUCT A microcomputer-controlled automatic steam sterilizer with six preprogrammed cycles that are operator selectable. The cycles employ either pre-vacuum conditioning by a series of pressure/vacuum pulses or gravity (downward displacement) with positive pulsing conditioning. Both processes dynamically remove air. All cycles are microprocessor controlled and pre-set at the factory. Times and temperatures are adjustable. There are up to 12 cycles, 6 of which are configurable by our service representative during installation. Custom names, up to eight characters in length, can be designated for each configured cycle. All cycle phases are sequenced and monitored by the control system, providing both audible and visual notification of deviation from certain operating parameters. APPLICATION For general-purpose pre-vacuum or gravity steam sterilization of hospital supplies, the temperature range is from 230 F to 275 F (110 C to 135 C). The temperature range for liquid cycles is from 219 F to 275 F (104 C to 135 C). Typical applications include wrapped and unwrapped hard goods, gowns or towel packs and liquids in self-venting or unsealed containers. The liquid exhaust is microcomputer controlled for linear and consistent liquid cool-down rate, which is programmable.

STANDARDS AND CODES The sterilizer shall comply with or meet the requirements of: ASME Code (Section VIII, Division 1) for Unfired Pressure Vessels Uniform Plumbing Code Intertek Testing Services ETL Listed to UL 544 Intertek Testing Services cetl Listed to CSA C22.2 No. 151 Seismic Anchoring Requirements per California Building Code MICROCOMPUTER CONTROLS Castle Sterilizers employ an Intel 80C-188 microprocessor on a dedicated controller (CPU). The controls consist of an operator switch panel, electronic input/output box, printer, mechanical chamber and jacket pressure gauges. When the supervisor password is enabled, a four-digit code must be entered to change cycle parameters. During a cycle, additional real time cycle information can be displayed by selecting the appropriate display screen. If the supervisor password control is disabled, cycle times and temperatures can be changed directly from the cycle select screen. Note: Selection of time and temperatures other than factory recommendations requires operator verification of the cycle efficacy. Controls are located above the door for convenience. A deflection barrier routes steam vapor and moisture away from the door and controls to assure the temperature of the components inside the control do not exceed their recommended ratings. If specified, the control panel can be located remotely from the sterilizer with up to 32.8 feet (10 m) of cable. The operator interface panel provides for on/off, cycle selection, door seal and unseal and status indicator lights. A two-line backlit LCD display identifies the cycle selected and provides descriptive status messages during the cycle. Audible and visible operator feedback is provided when a selection is made or a fault message is displayed. Temperature can be set, controlled and displayed in degrees Celsius or Fahrenheit, pressure in psia, BAR or kpa. Double door models have one printer and a complete operator interface at both ends of the sterilizer. The temperature of the discharge water is controlled by a temperature device to be less than 140 F (60 C). This switch also conserves water usage. Water in the chamber drain is continuously monitored during a cycle. If excess water is detected and can not be automatically corrected, a high water alarm alerts the operator. An RS 232 port is provided for serial communications for central data collection or remote service analysis. CYCLE DOCUMENTATION Using thermal paper for quiet operation, the printer documents cycle parameters and information. At cycle completion, a cycle performance record is printed. Paper is replaced by a drop in and quick feed method, and the printed strips can be either accumulated on an automatic take-up reel, or torn off for individual cycle storage. A last cycle duplicate print and paper feed switch is provided. The printer is located on the control panel and documents the following on a 200-dpi dot matrix printer (1.88'' wide print width): Process start time and date, total cycle time, sterilizer name and number Cycle parameters selected Cycle transition points, documenting time, temperature and pressure Process fault information messages with time of occurrence Cycle verification signature line CONFIGURABLE CYCLES During installation, our service representative can assign six of the 12 available preloaded cycles by using a software utility tool. Preloaded cycle selections include 5 Vacuum Cycles, 4 Gravity Cycles, 1 Bowie- Dick Test, 1 Leak Test and 1 Liquid Cycle*. Once cycles are assigned for each cycle selection switch, all parameters are held in memory, even if an extended power outage occurs. The factory-assigned cycles are: Two pre-vacuum cycles with factory set values of 3 minutes exposure at 275 F (135 C) and 16 and 3 minutes dry time respectively. Two gravity cycles with factory set values of 30 minutes exposure at 250 F (121 C) with 30 minutes dry time and 10 minute exposure at 275 F (135 C) with 30 minutes dry time. One Bowie-Dick Test Cycle at 273 F (132 C) for 3.5 minutes, with a momentary post vacuum phase to evacuate chamber steam. One vacuum leak test cycle at 268 F (131 C). *The liquid cycle, if used, is not for the sterilization of liquids intended for direct patient contact. PERFORMANCE When installed and connected to specified utility services, the system will provide accurate and repeatable performance. During the timed exposure phase, the temperature will be controlled at the drain by a sensor to 0.9 F (0.5 C) above the set point +/- 0.4 F (0.2 C). Temperature selectivity is in 1 F increments and timing functions are selectable in one-second

3 increments. Temperature control is by a continuous algorithm, a method called Proportional, Integrating, Derivative or PID.

CONSTRUCTION Body shall be constructed of an inner shell, outer shell (jacket), backhead and monel gasket ring. Chamber shells are 0.250'' (6.35 mm) thick hot rolled carbon steel with an interior surface of nickel or monel clad, 0.025'' (0.635 mm) thick. All pressure vessel construction is per ASME code requirements for working pressures up to 45 psig (310 kpa). The monel gasket ring holds a continuous, one-piece silicone O-ring gasket, 1'' (25.4 mm) in diameter. Gasket is replaceable without tools. The body assembly is thermally insulated with foil-backed fiberglass insulation, and a steam baffle is provided to prevent condensation from wetting the load. A spare threaded opening permits passage of thermocouple leads to monitor interior and load temperatures. Door is nickel-clad steel 0.50'' (12.7 mm) thick with tensile strength of 70,000-85,000 psi ( MPa) and is dished for maximum strength. Locking mechanism consists of eight heavy steel clamps, which unseal the door before allowing it to open. The closure uses filament-wound PTFE bearings at all high-load points and is totally lubrication-free. A series of interlocking solid-state door switches and relays stop steam from entering the chamber with the door unsealed, and prevent door opening with pressure inside. DOOR OPERATION Power Door is operated by permanently lubricated gearmotors and controlled by solid-state components for reliability and safety. On cycle complete the door unseals to vent excess steam. Door design minimizes possibility of injury to personnel or damage to the mechanism if an obstruction is encountered on door opening. The door can be opened manually in case of an emergency. Manual Door sealing is accomplished by handactuated air cylinders. Two handles are provided for opening and closing the door. Solid-state switches confirm that the door is properly sealed. An auxiliary means of manual control is provided in case of emergency. PANELING Front panels shall be constructed of nominal 0.050'' (1.27 mm) thick 300 series stainless steel. Trim panels are built in to provide fit-up with recessing wall or optional cabinet. Complete door assembly and drive mechanisms are enclosed by removable stainless steel panels eliminating projections and making the unit easier to clean. The door is lined with 1'' (25.4 mm) foilbacked fiberglass insulation.
