Water softener softener (Optional) In order to achieve good cleaning results, the washer-disinfector needs to operate with soft water. Hard water results in the build-up of calcium deposits on instruments, etc, and in the washer-disinfector. Mains water with a hardness level higher than 0.7 mmol/l (4° d – German scale) needs to be softened. This takes place automatically in the integrated water softener. – The water softener requires reactivation salt.
Water softener softener (Optional) Reactivating the water softener Please only use special coarse grained reactivation salt with granules of approx. 1-4 mm. Do not use other types of salt, e.g. table salt, agricultural or gritting salt. These could contain components which are insoluble in water which could result in damage to the water softener. If in doubt consult the Miele Professional Department. The salt container holds approx. 2 kg of salt.
Water softener softener (Optional) Filling the salt container Position the salt container as follows ^ Unscrew the filter insert from the salt container and remove. ^ Remove any mobile units from the cabinet. ^ Fill the salt container with reactivation salt and screw the filter insert back in place. ^ Unscrew the plastic cap situated in the top right-hand side of the cabinet. ,There will be a small amount of residual water in the cap. Take care as it may be hot from the previous programme.
Water softener softener (Optional) Run the reactivation programme ^ Close the door. ^ Open the stopcocks. ^ Select the REACTIVATION programme. The programme will run automatically. Then: ^ Switch off the machine. ^ Carefully unscrew the salt container, making sure any water pressure still remaining can depressurise. Do not use force! If the container will not come off manually please contact the Miele Service Department. ^ Replace the plastic cap. ^ Push the mobile unit back into the cabinet.
Automatic mobile unit recognition (Optional) In operating level C the automatic mobile unit recognition system (AWK) allocates programme places from 1 15 to mobile units with the correct coding. The unit coding (on the mobile unit) and the programme place with the corresponding programme (in the electronic control unit) have to match each other.
Automatic mobile unit recognition (Optional) Mobile unit coding Coding is effected through 5 Bits: The automatic mobile unit recognition feature assigns a programme place to a mobile unit. The mobile units must be coded with a magnetic strip (via a Bit combination). In operating level C, the only programme available for a coded mobile unit is the one assigned to the corresponding programme place.
Automatic mobile unit recognition (Optional) Mobile unit coding strip Setting mobile unit coding 15 different codes can be set. They are assigned to programme places 1 to 15. To set or alter the coding of a mobile unit with automatic recognition (AWK), proceed as follows: Under "System function, Selector switch organisation" the matching programmes have to be put into the first 15 programme places.
Automatic mobile unit recognition (Optional) ^ Set the programme place coding. ^ Put the magnetic strip back in the track. The magnetic strip must be placed in the track such that the Bit coding set out in the chart is visible through the round windows in the track. 22 ^ Place the track in the holder in the mobile unit and screw firmly in place. Bit 6 (WAK) is not a component part of the modifiable magnetic strip.
Areas of application This washer-disinfector can be fitted with a variety of mobile units, which can be equipped with a variety of modules and inserts depending on the type and shape of items requiring cleaning and disinfection. Select mobile units, modules and inserts which are appropriate for the application. Notes on the individual areas of application and examples of loading are given on the following pages.
Areas of application Loading the machine – Arrange the load so that water can access all surfaces. This ensures that it gets properly cleaned. – Do not place items to be cleaned inside other pieces where they may be concealed. – Hollow instruments must be thoroughly cleaned, internally and externally. – Ensure that instruments with long narrow hollow sections can be flushed through properly before placing them in inserts or connecting them to jets.
Areas of application Surgical instruments (OP) Surgical instruments should be stored for as short a time as possible before machine processing. The OXIVARIO or ORTHOVARIO processes should be used for instruments where there is a long delay between the time they are used and the time they can be reprocessed. See "Special processes" at the end of this booklet. Disinfection of surgical instruments and of those used for minimally invasive surgery should preferably take place thermally.
Areas of application Ophthalmology Opthalmic instruments should be cleaned and disinfected in a special mobile injector unit. The top level is fitted with various connections for hollow instruments, e.g. rinsing and suction hand pieces, and cannulae. Instruments are secured to the hose connectors in the mobile injector unit using the silicone holders and connectors in the rack.
Areas of application Anaesthetic instruments (AN) Anaesthetic instruments should be thermally disinfected using the DES-VAR-TD-AN programme. If this is not possible, they can be processed using a chemical disinfection programme. The water level in the machine should be increased when using a chemical disinfection programme. To establish the effectiveness of disinfection, consult the manufacturer of the disinfecting agent being used.
Areas of application Baby bottles (BC) Loading in an E 555 Baby bottles can be processed in E 135 containers, wide-necked teats in an E 364 insert and screw connection teats in an E 458 insert. – Ensure the level marker on the bottles is machine-washable. – If there is a delay of 4 hours or more before bottles can be washed, fill them with water to prevent residues from drying on.
Areas of application E 750 frame ^ Place the frame centrally in the top level of the E 555 mobile unit. ^ Hook one E 135 container onto each side of the frame. The angled positioning of the containers ensures that the jets of water reach right into the bottles. The two blocked corners in the inserts should be located over the positions marked with an X on the drawing. The jets of water cannot get into the bottles properly in these positions to clean them.
Areas of application Operating theatre shoes (OS) Polyurethane operating theatre shoes, and/or insoles should be cleaned and chemically disinfected at 60 °C. These can only be thermally disinfected (using programme SHOE-TD-75/2) if the manufacturer states that they are made of a suitably heat-resistant material. To establish the effectiveness of chemical disinfecting agents for disinfection consult the manufacturer.
Areas of application Transfer trolley for loading and unloading the machine ,When a disinfection process is being carried out according to nationally laid down hygiene standards (e.g. § 18 IfSG), the contaminated surfaces of the trolley must be disinfected, after the machine has been loaded, using a spray disinfectant in accordance with national health and safety regulations and § 18 IfSG. Disinfecting agents listed by DGHM (German institute for microbiology and hygiene) are also suitable.
Areas of application ^ Hang the mobile unit into the locating slots on the transfer trolley using both hooks. ^ To lift the mobile unit step down on the transfer trolley foot pedal. ^ Push the transfer trolley under the open door on the washer-disinfector as far as it will go.
