  • Page 7: Part One User Basics

    Part One User Basics Reading product manuals should not be a difficult and time-consuming process. This section provides a brief but thorough overview of the PresSura product by maximizing information with minimal reading. These few pages explain the purpose (The Instrument), and the operation (Useful User Information, Digital Interface Module, Alarms) of the unit.
  • Page 8 An example of negative pressure is a bathroom with an exhaust fan. When the fan is turned on, air is exhausted out of the room creating a slight negative pressure in the bathroom compared to the hallway. This pressure differential forces air to flow from the hallway into the bathroom.

  • Page 9: Operator Panel

    Operator Panel The DIM in Figure 3 shows the location of the digital display, keypad and lights. An explanation of the operator panel follows the figure. Figure 3: PresSura Operator Panel - Open Green / Red light The green light is on when all the conditions for proper room pressure are adequate. This light indicates the isolation room is operating safely.
  • Page 10 User Keys - Gray with Black Letters The four keys with black letters provide information without changing the operation or the function of the unit. TEST Key The TEST key initiates an instrument self-test. Pressing the TEST key activates a scrolling sequence on the display that shows the product model number, software version, and alarm values.

  • Page 11: Alarms
