SAFETY DOOR INTERLOCK
Your DDS 7000 is equipped with a cut-off switch beneath the door. (see Page 6) This switch
prevents the sterilization cycle from starting whenever the door is not properly closed. This switch also
interrupts the cycle if the door is opened during any cycle.
WARNING!
DISABLING THE DOOR LOCK AND OPENING THE DOOR AT ANY TIME DURING THE CYCLE PRI-
OR TO “CYCLE COMPLETE” MAY EXPOSE OPERATOR TO DANGEROUSLY HOT INSTRUMENTS.
DO NOT ATTEMPT TO REMOVE THESE INSTRUMENTS WITHOUT SUFFICIENT PROTECTION.
The DDS 7000 has an additional safety door lock mechanism, which prevents the door from open-
ing until the chamber temperature is at a “safe handling temperature”. In the event of an emergency,
requiring access to the chamber during any cycle, press and hold down the “cycle start” switch for 5
seconds. The door safety lock mechanism will unlock temporarily for a few seconds allowing access.
NOTE WARNING ABOVE: An Error Code will display notifying the operator of an interruption. Toggling
the “Standby/On” switch from “On” to “Standby” then back to “On” will clear the error message. To
restart the cycle, press “Cycle Start”. The DDS 7000 will first cool down and then restart the complete
cycle from the beginning.
FIRST TIME USE CYCLE TEST
After the sterilizer is connected to a properly rated and grounded outlet (see page 10) follow the opera-
tion procedures found on pages 17-19 with an EMPTY CHAMBER.
Make sure that air is blowing out of the exhaust stack during the cool down phase.
WARNING!
The dry air may be hot 265˚F (129˚C).
