Tuttnauer Tiva 2 Washer Disinfector Operating Instructions Leave a comment

Our Tuttnauer Tiva 2 Washer Disinfector Operating Instructions is a quick guide to cover the basic operation of this amazing thermo disinfector. In this article we will cover commissioning instructions, before use, programs, starting the machine, and display.*

Using the Machine

Before starting the machine, the operator in charge must have read and understood this whole manual, in particular the information on safety. Furthermore, before starting work, check that the machine is in order and that all parts subject to wear and deterioration are fully efficient.

Commissioning Instructions

These control operations (reported below) are performed to check if the machine works properly and should be performed when the machine installation is completed.

1 – Open the tap that supplies water to the machine

WARNING. The water should NOT flow into the tank; otherwise the water loading solenoid valves (in the lower compartment of the machine) are dirty or blocked due to long storage in the warehouse and therefore they must be cleaned. Check that there are no water leaks in the pipe fittings.

2 – Check that the suction tubes (located in the lower part of the machine) within the corresponding containers/tanks containing the liquids provided (detergent, neutralizing, and/or others), are correctly inserted.

3 – Using the main circuit breaker, supply power to the machine.

4 – Check that the water supply flexible hoses are properly connected.

5 – Start the machine using the ON-OFF switch (#1 below)

This shows the start/power switch for the Tiva 2 washer disinfector
Figure 1 – ON-OFF Switch Location

6 – At the beginning of the first cycle check the level probes of the liquid suction tubes (detergent, neutralizer and/or other): pull one tube at a time out of the container and check if the corresponding alarm flashes on the display, indicating the need for liquid refilling.

7 – After running 3-4 washing tests, clean the water filters placed in the lower compartment of the machine.

8 – Check that the drain trap does not show water leaks and is firmly secured to both the machine and the drain.

9 – Check if the pumps correctly suck washing liquids. To do this, check that the liquid rises along the tube connected to them.

Before Use

The Tuttnauer Europe b.v. thermodisinfector can be used for cleaning and disinfecting:

  • Medical instruments.
  • Keys, trays, containers.
  • Hollow instruments, e.g. suction cannulas, fixing them to the appropriate supports, using the suitable adapters.
Emergency Door Release

In the event of a blackout, or any other need in which it becomes difficult to open the thermodisinfector door, there is a manual emergency release that can only be activated if the door cannot be opened normally.

HAZARD. If the emergency release is used while a program is running, very hot water and chemicals may leak. Therefore, there is a danger of burns, scalding and irritation.

To access the emergency release:

  • open the lower door of the machine with the key;
  • remove the rubber cap (see #4 below);
  • a plastic cable can be seen inside the hole.
This shows the emergency door release access for the Tiva 2 washer disinfector
Figure 2 – Emergency Door Release Location

1 – Simply pull this cable manually and the door is released.

2 – Re-insert the cap after the operation.

3 – In case of program interruption, proceed with a new treatment of the load.

Preparing the Load
  • WARNING – The maximum weight that the open door can withstand is 12 Kg.
  • WARNING – The maximum volume available is 0.065 mW or 65 L.
  • WARNING – The maximum volume of the basket is 0.025 mW or 25 L.

The instruments to be washed must be placed on the relative basket, making sure that they do not overlap on one another.

  • Empty any residual liquids from the containers before inserting them into the tank, thoroughly washing any residue, e.g. disinfectant solutions.
  • Insert the individual instruments in the appropriate supports or baskets and never directly into the base basket.
  • Make sure that the instruments do not come out of the containers.
  • Make sure that the instruments do not hang from the grid bars.
  • Insert the hollow instruments into the appropriate injectors.
  • Insert the other instruments into the adapters with silicone insert.
  • The rinse arms must be free to rotate.
  • The cleaning quality depends on the correct loading of the instruments.
  • Position container-shaped objects so that liquids can flow easily and, if possible, place tall and heavy tools in the centre of the trolley.
  • Components with special geometries must be arranged so as to allow the water to flow out.
  • Introduce only suitable steel instruments, resistant to corrosion.
  • Introduce only plastic components thermostable up to 95°C.
  • To prevent possible corrosion, we recommend using only stainless steel instruments and tools, suitable for washing.
  • Nickel-plated and chrome-plated and/or aluminium instruments and tools may not always be suitable for machine treatment. They require special process conditions.
  • Objects made completely or partially of plastic must be resistant to high temperatures.
  • Before loading the machine, remove substances such as composites, cement and amalgam in compliance with current directives.
  • Transmission instruments with fibre optic rod are considered resistant, while fibre optic beams may be subject to premature wear.
  • If possible, disassemble the modular instruments following the manufacturer’s instructions and treat the individual parts separately.
  • Treat small instruments and parts in special inserts or closable baskets.
  • Before the automatic treatment, check that the lumen and hollow body instruments can be treated internally and remove any obstructions.
  • Carefully place the load in the supports.
  • Objects must not be put inside each other nor cover each other. Do not place objects so close to each other that they cannot be washed properly.
  • Arrange the load so that all surfaces can be reached by the washing liquid. Otherwise they will not be cleaned!
  • Place the objects so that the liquids can flow out without hindrance.
  • Place tall or heavy objects in the center of the basket.
  • When arranging the load, make sure that the spray arms are not blocked by the load itself.
  • Distribute the objects evenly in the baskets.
  • After the treatment the transmission instruments must be cleaned according to the manufacturer’s instructions.
  • After the treatment, before reusing the transmission instruments, check that they work properly, e.g. by spraying liquid in the sink.

When the base grid is used together with the injectors, make sure to push the grid all the way back against the rear wall of the tank, so that the injectors can be perfectly fixed on their connection tube at the bottom of the tank itself.

To select the programs available, use key 1, 2 or 3 (on the control panel shown below) depending on the most suitable program for the level of dirt of the load.

This is the Tiva 2 Control Panel
Figure 3 – Control Panel

The following table shows the correct programs for each type of load.

ProgramUse
SHORT
Program 1
Washing and disinfection program for the treatment of instruments with normal dirt, with times and dosages lower than Program 2.
STANDARD
Program 2
Filling of the dosing system with additive for final rinsing or neutralizing after filling or replacement of the container. Program tested and certified according to EN ISO 15883.
INTENSIVE
Program 3
Washing and disinfection program (not EN ISO 15883 certified) specific for the treatment of instruments with stubborn dirt.
Rinse Cold WaterFor rinsing water and salt solution of a particularly dirty load, e.g.: to eliminate coarse dirt or disinfectant residues before treatment and to prevent dirt from drying or the formation of limescale until a complete program is started.
DryingAdditional Drying

Program structure:

  • Drain – It is used to empty the washing tank.
  • Pre-wash – Pre-wash is necessary to eliminate coarse dirt and foamy substances.
  • Wash – Depending on the load, washing normally takes place at 45°C – 65°C, adding the appropriate detergent.
  • Rinse – The rinsing operation eliminates and neutralizes the chemicals of previous washes.
  • Disinfection – To prevent the load from being subject to corrosion or patinas, purified water (if available) should be used during the disinfection phase.
  • Drying – Sufficient drying reduces the risk of corrosion caused by the residual humidity on the load.
Starting the Machine

After checking the integrity and full efficiency of the machine, proceed with start-up.

  1. Power the machine using the main circuit breaker.
  2. Start the machine using the ON-OFF switch (Fig. 1) and open the door (key 5 Fig. 3) to introduce the baskets.
Before starting the program
  • Check that the filters, positioned on the bottom of the tank are perfectly clean. Clean them, if necessary.
  • The nozzles of the upper and lower spray arms must be free and clean.
  • Basket and products must be arranged correctly.
  • The rinse arms must be able to rotate freely. The machine constantly monitors the rotation speed during the program.
  • Liquid containers must be sufficiently filled. Check for any messages on the display before starting the program.

Closing the Door:

  • Introduce the basket and load the instruments.
  • Close the door and push it until the lock is activated. The door can be unlocked and opened at any time before the program starts, by pressing the key (5 Fig. 3).

Selecting the Program:

  • To select the programs available, use key 1, 2 or 3 on the control panel (Fig. 3).
  • Choose the most suitable program depending on the level of dirt on the products to be washed.
Program 1
"SHORT"
This is a washing and disinfection program for normal dirt, sufficient for daily used instruments.
Program 2
"STANDARD"
This is a program tested and certified according to EN ISO 15883 with filling of the additive dosing system for final or neutralising rinsing
Program 3
"INTENSIVE"
This is a specific program designed for treating instruments with stubborn dirt.
Starting the program
  • WARNING. Inattentive and superficial use of electrical devices may lead to risks for the operator.
  • Tuttnauer Europe b.v. is not liable for possible damage caused by uncontrolled use of the device.

After selecting the program with relative key, the display shows the selected program and the operating time and temperature.

  • To start a program, press the START key (Fig. 1).

Program Execution

  • Once the program has started, its progress can be followed on the display. The display shows the program phases during operations.

Pre-Wash

  • Pre-wash is carried out with cold water (optional softened water) and without liquids. It mechanically dissolves encrusted organic materials and all proteins on the surface of the instruments. Avoid too high water temperatures.

Wash

  • It is the actual cleaning cycle. The cleaning tank heats up until it reaches the specific temperature for the selected program, a temperature that remains stable for the holding time. The cleaning liquid is automatically introduced before the start of the holding time.

Rinse

  • Rinsing is carried out with cold water, if the machine is equipped with the second pump (optional) it is possible to carry out the neutralisation cycle by introducing neutralising liquid which is designed to reduce the alkalinity and clean the instruments from residues soluble in acid, e.g. limestone and rust.

Disinfection

  • Thermo-disinfection is carried out with water, if the machine is equipped with the second pump (optional) it is possible to introduce the rinse aid to carry out the neutralization cycle which is designed to reduce the alkalinity and clean the instruments from residues soluble in acid, e.g. limestone and rust.

Drying

  • The instruments are dried internally and externally with filtered hot air. Good drying reduces the risk of corrosion caused by the residual humidity on the load.
  • Instruments with a very small internal diameter must be dried further.

 

  • WARNING. The program can be interrupted at any time. However, it must be remembered that once interrupted, it must restart from the beginning. Only if it is interrupted in the drying phase can the cycle be considered completed successfully. The instruments must be dried.
Program End

The message «Successfully completed» on the display indicates that the program has been carried out correctly.

Unlock the door by pressing the key (5 Fig. 3) and open it.

Open the door immediately after the end of the program to avoid condensation forming.

Check the results at the end of the cleaning process. The instruments must be completely clean and dry.

Hollow instruments with a small internal diameter must be dried further with air.

  • Check hollow instruments and retreat them if necessary.
  • The hole (lumen) of hollow instruments must be free.
  • The injectors must be correctly placed on the connection tube in the cleaning chamber.
  • The nozzles and connections to the base grid must be firmly fixed.

If these checks are positive and the program has been carried out without interruptions or malfunctions, the load has been successfully cleaned and disinfected.

Extracting the load

At the end of the program and when extracting the load:

  • Do not force to open the door to avoid damaging the device and/or the leak of toxic steam.
  • Particularly large instruments can be very hot at the end of the program. Allow instruments, containers and inserts to cool down before removing them.

Failure to follow these recommendations can cause burns.

Display

The LCD display shows the status of the machine. The images show the various phases and the current operation. For example, if the machine is loading water, the display will show the image of the tap, of the water flow meter and of the water being loaded: if water is purified droplets will be light blue, if water is cold droplets will be blue and if water is hot they will be red. The images are animated, to show how the current operation evolves.
