    SAFETY PRECAUTIONS ® ® The following Safety Precautions must be observed when operating or servicing this AMSCO Evolution Series 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 20 Personnel must properly shutdown the sterilizer and retain the power key at all times while cleaning the sterilizer chamber. Avoid personal injury from bursting bottles. Liquid sterilization cycle must only be used for liquids in borosilicate (Pyrex) flasks with vented closures. WARNING –...
  • Page 21 WARNING – SLIPPING HAZARD: To reduce slippery conditions, keep floors dry by immediately wiping up any spilled liquids or condensation in sterilizer loading and unloading areas. CAUTION – POSSIBLE EQUIPMENT DAMAGE HAZARD: Allow thermostatic steam 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.

    For SFPP sterilizers, if the SFPP cycle is used exclusively, there is no need to run a daily Dart (Bowie-Dick) test. If prevacuum cycles will also be run on the same sterilizer, then a daily Dart (Bowie-Dick) test must be run. NOTE: The Dart (Bowie-Dick) test cycle is not a test for adequate exposure to heat in terms of time-at-temperature.

    5.1 General Use this manual to become familiar with control locations and functions before operating the sterilizer (refer to Figures 5-1 through 5-14). 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 41: Sterilizer Key Switch Operation

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

  • Page 42: Control

    5.4 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 Figures 5-3 and 5-4. • Out-of-cycle displays are used to start cycles, or set up and adjust sterilizer operation.

  • Page 43: Alarm Displays

    5.5 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.
