ABORTING A CYCLE
In the event of an emergency that requires aborting the sterilization process, the following procedure
should be used.
To abort the DDS 7000 in any cycle phase, toggle the lower portion of the “Standby/On” switch to the
“Standby” position. An error code will display in the red LED window, alerting user of a power interrup-
tion. An audible tone will sound, and the cycle phase LED will flash notifying the user of the phase at
which the interruption occurred. There is no recovery from an aborted cycle.
If the chamber temperature is above 122°F (50°C), Safety Door Interlock will be engaged. In order
to open the chamber door, switch the Standby/On switch to “Stand by” and then back to the “On”
position and activate the Cycle Start Switch. The cooling fan will turn on and cool the chamber down
to 104°F (40°C). Once the chamber cools below 113°F (45°C), the safety door interlock will disengage
and you will be able to open the door.
WARNING!
If immediate access to the chamber is required, hold down the “Cycle Start” Switch for 5 seconds.
The Safety Door Interlock will unlock for a few seconds allowing the door to be opened. Depending
on where in the sterilization cycle the interruption occurred, the contents of the chamber could be
extremely hot. Appropriate protective equipment should be worn when handling the contents of
the chamber.
To begin sterilization after aborting a cycle, follow the steps above. If the unit is restarted after an error
code has been displayed and if the chamber temperature is at 122°F (50°C) or above, the unit will first
cool down the chamber temperature to 104°F (40°C) and then restart the sterilization cycle from the
beginning.
RESETTING THE TEMPERATURE OVERLOAD SENSOR
The DDS7000 incorporates a temperature overload sensor designed to interrupt power to the heater
should operating temperatures exceed normal levels. To reset the sensor:
1. Unplug the sterilizer.
2. Turn sterilizer around to face the back.
3. Remove exhaust box, if installed, on the left-hand side of the sterilizer back panel.
4. Locate the round, black, plastic cap on the upper left-hand corner of the back panel.
5. Remove black cap.
6. Depress the red button in center of opening while listening for a small “click.”
7. Re-install black cap and exhaust box (if installed).
8. Plug sterilizer back in to run a test cycle to ensure that the sterilizer will heat.
9. After completing a test cycle, make sure that the unit is loaded according to instructions using
Dentronix racks or shelves.
