Our Tuttnauer T-Edge Operating Instructions is a quick guide to follow up on our Intro to the Tuttnauer T-Edge. In this article we will cover the basics of turning on the sterilizer, filling it with water, and setting the date and time.

Turning on the Device

Plug the power cord into the socket on the rear panel of the autoclave (see the rear view in our Intro blog) and into the wall outlet.

This is the location of the ON/OFF switch on the Tuttnauer T-Edge Steam Sterilizer

Filling Water

Tuttnauer white caution statement labelIn the beginning of each day, check water level in the reservoir.

Note: The Improper Water Level Icon  appears when the water reservoir needs to be filled. See the ‘filling procedure’ below.The Improper Water Level Icon for the Tuttnauer T-Edge

A General Alarm symbol will appear.The General Alarm symbol for the Tuttnauer T-Edge

Properly filling the water reservoir displays the Proper Water Level icon. See the ‘filling procedure’ below.The Proper Water Level Icon for the Tuttnauer T-Edge

The Water Level icon appears when the water level in the reservoir is full. See the ‘filling procedure’ below.The Water Level Icon for the Tuttnauer T-Edge

This shows the T-Edge waste water tank is full.

This shows the T-Edge waste water tank is empty..

Tuttnauer white caution statement labelBefore filling the reservoir, verify that the autoclave is idle and there is no pressure in the chamber.

Filling Water in the Reservoir

Note: Use only water having the characteristics stated in the Water Quality* table below. Using tap water will clog the system and invalidate the manufacturer’s guarantee.

SubstanceFeed WaterCondensate
Evaporate residue≤ 10 mg/l≤ 1.0 mg/l
SiO₂≤ 1 mg/l≤ 0.1 mg/l
Iron≤ 0.2 mg/l≤ 0.1 mg/l
Cadmium≤ 0.005 mg/l≤ 0.005 mg/l
Lead≤ 0.05 mg/l≤ 0.05 mg/l
Reso of heavy metals
except iron,
cadmium, lead
≤ 0.1 mg/l≤ 0.1 mg/l
Chloride (Cl)≤ 2 mg/l≤ 0.1 mg/l
Phosphate≤ 0.5 mg/l≤ 0.1 mg/l
(at 20°C)
≤ 15 µs/cm≤ 3 µs/cm
pH value5 to 7.55 to 7
Hardness≤ 0.02 mmol/l≤ 0.02 mmol/l
AppearanceColorless, clean, without sediments
*Compliance with the above data should be tested in accordance with acknowledged analytical methods, by an authorized laboratory.

To fill water in the reservoir:

Lift up the water reservoir cover (see below)

The water reservoir cover location on the Tuttnauer T-Edge B-class Steam Sterilizer

Pour water into the reservoir through the water filter on top of the autoclave unit. In case you fill too much water, it will spill on the counter.

The clean water level indicator will change from a red water droplet symbol to a blue water droplet, as shown below.

This shows the T-Edge clean water level indicator has turned to blue.

Please note: Prion program requires the demineralized water level in the reservoir to be filled to the in maximum level in order to start the program, otherwise an alert will be prompted “please fill water tank to full for start”.

This shows the T-Edge Prion program and tests that are available.

Setting Date and Time

Note: The initial log-in including the setting of drying time as well as other initial parameters will be performed only by a qualified technician upon installation.

On the main screen, press the menu symbol to open the settings screen.The Menu Icon for the Tuttnauer T-Edge

Note: The only functionality to be performed by the user (on a regular basis) is the setting of the date and time.

This shows the T-Edge settings screen.

Press the Set Date and Time icon to open the Set Date and Time screen.The Set Date and Time Icon for the Tuttnauer T-Edge

This quick option enables the operator to set the machine date and time. Select day, month and year, as depicted:
