Atherton 1 Installation A Technical Data Sheet showing all the utility and space requirements for the installation of the equipment was sent to the purchaser after the order for this sterilizer was received. The clearances requested are necessary for easy installation, proper operation and maintenance of the equipment. If you are not in possession of these documents, and require them, you can order additional copies from the ATHERTON office in your state, giving the serial number and model number of the equipment. After installing the sterilizer according to the instructions provided, complete the following checklist to ensure that the installation is correct and complete. If you are in any doubt as to the correctness of the installation, you are strongly advised to contact your ATHERTON office, as incorrect installation and /or commissioning can invalidate your warranty. Installation and commissioning should only be carried out by fully qualified personnel, familiar with installing this type of equipment. Ignorance or carelessness can cause death.

Over current protection is required in the power supply to the unit.

1.1

TRANSPORT PROTECTION Your Tangent series sterilizer is supplied with transport protection and this must be removed before installing your sterilizer.

Atherton 1.3

INSTALLED CHECK LIST Isolation valves for maintenance purposes should be installed in steam and water lines, at a point near to the sterilizer. Electrical isolating switch should be provided to the sterilizer. Check that the electrical supply is rated as per Atherton requirements and is installed by a qualified electrician to AS 3000 and the requirements of the local supply authority. If multiple units are installed adjacent to each other, isolating valves and switches should be installed for each piece of equipment. Ensure the electrical connection can be made before placing the unit in its final position. Check that the sterilizer chamber is level, and is at the height shown on the equipment drawing. Place a spirit level on the sterilizer end frame or chamber floor in both directions, to ascertain correct positioning. If a recessed unit has been ordered, the panel trim should be tight fitting against the wall opening. Reticulated steam supply line MUST provide condensate free steam at not less than 0.97 dryness factor. Steam supply pressure should be between 400-500 KPa. Cold water supply to the sterilizer should be between 200-500 KPa. Use the adjustable feet at base of the unit for levelling.

Atherton 2 GENERAL NOTE ABOUT TOUCHSCREEN DISPLAY Your Tangent Gorilla sterilizer is fitted with a state of the art hi-resolution Exter T100 touch screen. To aid with system navigation a commonality of function has been programmed into the design of the screen layout. For the most common screens the touch screen area has been divided into three sections, a title bar, the main body area and the bottom navigation bar. 2.1

TITLE BAR FUNCTIONALITY The area at the top of the screen is referred to as the title bar for “most” screens this area acts as a return to previous screen function. The reason not all screens have this functionality is due to the fact that for some functions it is necessary that the user complete a series of tasks which may require a set navigational sequence. However for the vast majority of screens touching the title bar will return the user to the previous screen. For example from the Main Menu if the user selects the Help Menu button the Help Menu screen is displayed, then to return to the Main Menu the user can either choose the button at the bottom of the screen or use the title bar:

HELP MENU

Selecting the title bar from the Help Menu returns the user to the Main Menu. 2.2

MAIN AREA FUNCTIONALITY The middle of the screen is referred to as the main area and contains the functionality buttons and any display items. For example the main area of the Analogue Readings screen contains the analogue input values displayed in dial form:

Atherton 2.3

BOTTOM NAVIGATION BAR The bottom area of the screen is reserved for navigation and committing a change to the memory. Using the above example of the Analogue Readings screen the bottom navigation bar allows the user to return to the previous screen or the Main Menu – referred to here as the Home Screen or the Help Menu:

2.4

CYCLE START SCREENS Once a cycle has been selected from the cycle family screens the system displays the parameters for the chosen cycle. If the user is satisfied that the parameters are appropriate the user then selects ‘START CYCLE’.

The cycle start screens all follow the same format – the parameters are displayed in the centre of the screen, a user with the required access level can alter the parameters for all variable cycles. The user then has the option of either starting a cycle or cancelling and returning the cycle family screen.

2.5

OPERATING SCREENS The operating screens display the sterilizer state while running a sterilizing or test cycle. All the operating screens are similar; there are three sections in the green background area of the screen and a lower navigation bar. In the green background area the three sections are; the parameters section at the top 12 of 77

Atherton which is unique for each cycle, the temperature and pressure section in the middle, and the cycle stage, elapsed time and warning text section in the lower third. On the navigation bar the user can view a cycle trend, the full set of temperature and pressure readings, and a system schematic, as well as abort the cycle.

2.6

TREND SCREEN The cycle trend screen has the capability to display historical information. If the user touches the middle of the trend graph the trend stops updating and a navigation bar appears at the base of the trend graph. Use the arrows to move back forward in time and then to zoom in or out.

Atherton 3 USER SECTION 3.1

RUNNING A CYCLE This section describes the procedure for setting the sterilizer to run a cycle, the procedure is the same for all cycles – including favourites. In summary the procedure is: 1. Select cycle family. 2. Select specific cycle or favourite. 3. If the cycle parameters are correctly matched to the items to be sterilized select the start cycle button.

3.1.1 Select Cycle Family This demonstration assumes the user has started from the home screen.

Select Cycle Family – In this case we are going start a Pre Vac Cycle, therefore select the PRE VAC CYCLES button: This will bring up the Pre Vac Family screen – this screen displays all the available cycles that have a pulsing Pre Vacuum stage. At this stage it important to note that the above steps are repeated for General Purpose cycles, Special Purpose cycles and Favourites cycles each cycle family has its own Cycle Family screen from there the user selects the unique cycle.

3.1.2 Select Specific Cycle Using the buttons on this screen we select the PRE VAC CYCLE button

The operating parameters that will be applied to the selected cycle are displayed in the centre of the screen. Because the cycle we have chosen is a variable cycle we have the option of modifying the parameters. This option is 15 of 77

Atherton only available to users who have supervisory level access. To modify the parameters touch the value, in this case I am going to change the sterilizing temperature and the holding time. Before I can modify these parameters I have to enter the supervisor password:

Once I have entered my password I then touch the parameter again and this time the parameter input box appears:

In this case I am going to change the sterilizing temperature from 134°C to 121°C and at the same time alter the holding time 15 minutes.

Now that I am happy with the operating parameters I select the START CYCLE button. 3.1.3 Select The Start Cycle Button

This will cause the display to change to the Operating Screen – each screen is tailored to display the parameters of the cycle, in this case the Pre Vac Cycle has three operating parameters: Sterilizing Temperature, Holding Time & Drying Time:
