Intended Use

This washer-disinfector can be used to

clean, rinse, disinfect (thermally and

chemically) and dry a wide range of

reusable medical devices.

National health and safety regulations

regarding disinfection must also be

observed.

The cleaning programme as well as any

chemical agents must be chosen

according to the type of soiling and

load being processed.

Follow the manufacturer's instructions

(according to EN ISO 17664) on how to

process their items by machine.

The agents used for processing the

products should be selected to suit the

level of cleaning required as well as the

method of analysis used.

Examples of application areas:

– surgical instruments,

– minimally invasive instruments,

The cleaning result must ensure that

the instruments can be disinfected

correctly, that no residues are left

behind, that subsequent sterilisation

can be carried out and that the

unit, module, insert etc.) is important to

ensure the adequate cleaning of the

load. Examples are given in the section

"Areas of application".

Where disinfection is required for the

protection of staff and/or patients, a

thermal disinfection programme, e.g.

the DESIN vario TD programme, should

be selected.

The washer-disinfector is programmed

to carry out the final rinse with mains

water or with processed water of a

quality to suit the application (e.g. aqua

destillata, purified water, de-ionised

water, demineralised water).

The parameters for thermal disinfection

according to EN ISO 15883-1 (A₀

concept) vary depending on the

disinfection standard required. They

are 80 °C (+ 5 °C, - 0 °C) with a 10 min

holding time (A₀600) or 90 °C (+ 5 °C,

- 0 °C) with a 5 min holding time

(A₀3000). An A₀value of 3000 is

suitable for deactivating the HBV virus.

This machine complies with EN ISO

15883 for validation purposes.

When cleaning narrow lumen

instruments e.g. those used for

minimally invasive surgery, an

intensive internal cleaning result is

imperative. The Vario-TD and

Instruments with very narrow lumen

must be manually pre-rinsed where

necessary. Follow the instrument

manufacturer's instructions on how

to handle them.

Fully demineralised water should be

used for the final rinse when possible to

ensure no marks are left on the load

and to avoid corrosion. If the water

used contains more than 100 mg

chloride/litre there is danger of

corrosion.

OP-containers can be disinfected

thermally in the CONTAINER

programme, or chemically. If anodised

aluminium containers are used the final

rinse must be carried out with fully

demineralised water. These containers

must not be processed with an alkaline

cleaning agent in a 93 °C programme

with 10 minutes holding time

(according to § 18 IfSG).

process by adding two additional

dispenser pumps together with a buffer

tank for hydrogen peroxide solution

H₂O₂. The DOS 2 dispenser is used for

the H₂O₂solution.

The ORTHOVARIO process uses a

special tenside based cleaning agent

in the first cleaning phase and then

releases active oxygen in the second

phase with a pH value of between 10.0

and 11.0 and a slightly higher

To use the ORTHOVARIO process the

particularly suitable for the processing

of surgical instruments where existing

procedures are not satisfactory.

It is particularly suitable for instruments

such as those used in high frequency

surgery, orthopaedic surgery as well as

for instruments which have dried out

because of the length of time between

using them and reprocessing them. It is

also suitable for antiseptic

Because of its oxidising effect it

must not be used for titanium

implants, and in particular colour

colded ones.
