Tuttnauer EZ9Plus User manual

“Operating”
EZ9Plus & EZ11Plus
Instructions on:

Step 1
Turn the unit on by setting
the rocker switch mounted
on the right side of the
front panel to the “On”
position.
NOTE: The EZ11Plus has an automatic pre-heating mode which activates automatically in the “Wrapped Instruments,
Pouches”, “Handpieces”, and “Custom A” cycles. Use caution since pre-heating will make the bottom of the chamber hot.
(This feature is not active in the EZ9Plus.)

Step 2
Open the door when
“System Ready” is
displayed on the screen

Step 3
•Place your thumb on the plastic
door cover and the other
fingers in the handle pocket.
•Pull the handle until the latch
of the door is released.
NOTE: This machine is equipped with an electronic door lock. The door will not open when the sterilizer
is running a cycle, when the power is off, or when the display screen does not read “System Ready”.

Step 4
•Fill the reservoir by pouring steam distilled
water, gently, into the front funnel until it
reaches the top of the blue area on the
level gauge.
•This reservoir is designed with an overflow
and filling the reservoir above the safe
level as indicated on the Front Fill Funnel
will cause excess water to spill out below
the machine onto the counter

Step 5
Select a program to run by
using the “UP” or “DOWN”
arrow keys.
(Programs can only be selected when the door is open.)

the handle.

Start the cycle by pressing
the START/STOP key.

At the end of a successful cycle,
the screen shows the “Cycle
Ended” message and the door is
automatically unlocked.
Open the door and use the tray handle or wear heat-resistant gloves to remove the load from the autoclave.
On completion of the cycle, the load should be visually inspected to ascertain that the load is dry, and that
sterilization indicators have made the required color change.

Use only FDA cleared chemical & biological indicators designed for steam sterilization
that are compatible with the particular sterilization cycle temperature and exposure
time being monitored.
At least once a week use a biological spore test (Bacillus Stearothermophilus) in any
load to insure proper sterilization (be aware testing standards may vary; contact
appropriate state/local agencies for specific sterilization guidelines for your office).
Always follow the spore test manufacturer’s instruction.
Be sure to follow all maintenance instructions as outlined in section 12 of the
Operator’s Manual.
