•
Ensure the medical device has been cleaned according to the hospital standard procedures before
performing high-level disinfection with Stella System A. Tristel Clean for Stella, Tristel Pre-Clean Wipes or
Tristel Clean are recommended. Please refer to the medical device manufacturer’s care card or material
compatibility approval list.
• Disinfect hands and wear appropriate Personal Protective Equipment (PPE) when handling disinfectants
and medical devices.
• Do not attempt to move Stella whilst it is filled with solution.
Step 1
Push and hold the ON button on IQ until you hear a beep and follow the instructions shown on the
screen. IQ performs a short self-check.
Step 2
When prompted by IQ, place a clean device into the device compartment. Position the device in a way that
best fits the shape of the compartment, ensuring any connectors or non-immersible parts are placed outside
of the tray via the designated cut-outs. If the device is completely submersible, seal the cut-outs with the
grommets provided.
Devices that do not fit correctly in the device compartment must not be used in the Stella System. Ensure that the Stella
lid can be completely closed.
Step 3
Any small re-usable parts from the device should be placed in the Small Parts Tray with the Lid closed and
positioned into one of the two positions available within the device compartment, t0 the left or right of IQ.
Step 4
Prepare five litres of Tristel Fuse for Stella working solution in the Stella Jug in accordance with the user
instructions.
Step 5
When prompted by IQ pour five litres of Tristel Fuse for Stella disinfectant into the device compartment.
It is recommended to position the Jug on the outer wall of the Base, just right of IQ, and tilt the Jug slowly, supporting
the base of the Jug with one hand. All five litres must be added. The disinfectant will overflow over the edges of the inner
compartment into the overflow compartment of the Base. It will drain out immediately.
Step 6
Allow up to 10 seconds for the liquid sensor to detect the Tristel Fuse for Stella working solution in the Base.
The correct level of disinfectant automatically triggers the contact time countdown. An audible beep confirms
the start of the five-minute disinfection cycle.
If Tristel Fuse for Stella is not added to Stella within 10 minutes,
the cycle will be automatically aborted by IQ.
Step 7
Place the Lid onto the Base, ensuring it is closed tightly. Closing the Lid will displace more disinfectant
solution into the overflow compartment. IQ displays the five-minute contact time countdown.
Do not turn off IQ during the contact time as this will lead to ineffective disinfection and the
disinfection cycle will be recorded as invalid, with no Validation Code.
