  • Page 13: Safety Precautions

    SAFETY PRECAUTIONS ® The following Safety Precautions must be observed when operating or servicing this Amsco Evolution™ Medium Steam Sterilizer. WARNING indicates the potential for personal injury and CAUTION indicates the potential for damage to equipment. For emphasis, certain Safety Precautions are repeated throughout the manual. It is important to review all Safety Precautions before operating or servicing the unit.
  • Page 14 Personnel must properly shutdown the sterilizer and retain the power key at all times while cleaning the sterilizer chamber. WARNING – SHOCK AND BURN HAZARD: Disconnect all utilities to sterilizer before servicing. Do not service the sterilizer unless all utilities have been properly locked out.
  • Page 15 CAUTION – POSSIBLE EQUIPMENT DAMAGE HAZARD: Allow thermostatic traps to cool down to room temperature before removing cover. Since there is nothing to limit expansion, the bellows may rupture or fatigue if trap is opened while hot. Actuation of safety relief valves at less than 75% of rated pressure can allow debris to contaminate the seat and cause the safety valve to leak.

    5.1 General Use this manual to become familiar with control locations and functions before operating the sterilizer (refer to Figure 5-1 through Figure 5-16). The controls for this sterilizer are contained within the control touch screen. Control touch pads appear on the screen as needed during each operation.

  • Page 33: Figure 5-2. Sterilizer Key Switch And Countdown To Shutdown Timer

    • Sterilizer Key Switch Refer to Figure 5-2. Key Switch Function: The key switch has two positions – 0 (Off) and 1 (On). When power is supplied to sterilizer, the key should be in the 0 (Off) position. When the key is moved to 1 (On) position, 24V dc power is applied to control and power-up sequence begins.

  • Page 34: Control

    5.3 Control Control displays can be divided into two categories, those occurring when the sterilizer is “out-of-cycle” and those occurring when the sterilizer is “in-cycle.” Typical out-of-cycle and in-cycle displays are shown in Figure 5-3 and Figure 5-4. • Out-of-cycle displays are used to start cycles, or set up and adjust sterilizer operation.

  • Page 35: Alarm Displays

    5.4 Alarm Displays Alarm displays tell operators and technicians when the sterilizer is experiencing an abnormal condition. Alarm conditions can be caused by failure of utility supplies or sterilizer components. 9, T , details the steps an operator can take ECTION ROUBLESHOOTING to solve most alarm conditions.

  • Page 36: Cycle Selection Touch Pads

    Cycle status and control messages are shown on a 213 mm (8-4/10 inch) color graphics display. Cycles can be started or aborted using the touch screen pads. Cycles and cycle values can be set using the Change Values procedure (accessible from the sterilizer cycle select screen).

  • Page 37: Change Values Control Screens

    ® The Amsco Evolution™ sterilizer control can be programmed to retain values for up to 12 separate cycles. The four cycles shown on the cycle select screen are the factory default cycles. Up to eight additional cycles can be programmed and displayed. It is the responsibility of the healthcare facility to validate any modification to cycles.
