    Functional test prior to use. General requirements to be met by the installation location Use Getinge Sterilization AB’s installation drawings for design and building purposes when determining the necessary dimensions and design. Experience has shown that particular attention should be paid to the following points.
  • Page 8 Sterilizers with vertically-operating doors: These models have a generous gap between the front plates of the sterilizer and the wall opening. The gap must be covered with suitable fitting pieces. Getinge sells an add-on system for this purpose. • Sterilizers with horizontally-operating doors There are two variants: either the front plates are designed to lie outside and overlap the wall, or a gap is left between the wall and the plates.

  • Page 9: Unpacking

    Unpacking • Check when unpacking the equipment that the order No. of its data plate conforms with the ordering No. of the documents. • Check that the sterilizer is faultless. Any transportation damage should be reported within seven days to the transport company that was responsible for delivery.

  • Page 10: Connection

    Connection Certain types of installation work, water and electrical, for example, should be done by authorized technicians. If the work is not done properly, injury and damage may result. Faulty installation work invalidates the warranty on the product supplied. Pipework and electrical wiring should be done in a professional manner so that the service compartment looks workmanlike and provides a practical workplace which minimizes the risk of accidents.

    ADVICE AND INSTRUCTIONS Manual interventions in the process When faults occur during a process because of interruptions in the supply of media or component faults, the process may, after an alarm has been triggered, get stuck in a phase from which the control equipment cannot proceed.

  • Page 42: Faulty Analog Sensor

    Faulty analog sensor If an analog pressure sensor or temperature sensor becomes faulty during a process, the process stops. The type of fault does not allow restarting of the process, since the sensor fault persists after acknowledgement, even if it is not indicated again. Another consequence of a faulty analog sensor is that no pressure or temperature controller becomes operative.

  • Page 43: External Safety Interlock Fault

    Normally the operator is informed at the start of the next process if an output is set to manual mode. Despite this, the status must always be reset to auto mode immediately on completion of work. When using this method, the blocks that prevent hazardous situations from arising are removed.

    Solenoid valves Hum from a solenoid valve may be a forewarning of overheating due to abnormally high electric current through the solenoid. Generally an alternating current rises when the circuit impedance decreases and this happens when the solenoid is no longer surrounded by a closed iron circuit.

    Foreign particles in the valves may block the valve in the open position and cause leaky operation, so that open doors close or media valves accidentally open, for example. Observe extreme cleanliness when working on control valves. Be aware of the risk of foreign particles in the valves, which may cause unintended operation.

    Pressure testing will reveal any leakage. Cleaning Our first recommendation for cleaning is an environment-friendly and harmless cleaning agent produced specially for GETINGE plate-type heat exchangers. The agent, trade mark “Limeclean” contains special ingredients. It should not be confused with similar products available on the open market.
