Opening and closing the door The door can only be opened when: Opening the door – the lab glassware washer is connected to the electrical supply, ^ Press the 5 door button, hold the door handle and open the door. – the red ("emergency cut-off") power switch is in the I-ON position, – the I-0 On-Off button is pressed in, and – no program is running. The door on the clean side (G 7826) can only be opened when: – DESIN (disinfection) programs have been correctly completed.
Automatic mobile unit recognition (AWK) In operating level C the AWK attributes a fixed program place to a mobile unit with valid coding. Program places 1-15 are reserved for the AWK automatic mobile unit recognition. The unit coding (on the mobile unit) and the program place with the corresponding program (in the "Profitronic" electronic control unit) must match. ^ Each mobile unit must be coded before being used for the first time. See "Mobile unit coding".
Automatic mobile unit recognition (AWK) Mobile unit coding strip Setting mobile unit coding 15 different codes can be set. They are assigned to program 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 organization" the matching programs have to be put into the first 15 program places. Prog.
Automatic mobile unit recognition (AWK) ^ Set the program place coding. ^ Place the track in the holder of the mobile unit and screw firmly in place. Bit 6 is not an integral part of the modifiable magnetic strip. Make sure that you code mobile units with side coupling to a track where Bit 6 is set to I. Mobile units without side coupling must be coded with a track that does not have Bit 6. ^ Put the magnetic strip back in the track.
Application The labwasher can be fitted with a variety of mobile units, baskets and inserts, depending on the cleaning application desired. Check before cleaning – Are the items to clean correctly sorted, loaded and connected? – Are the spray arms clean and can they rotate freely? – Is the filter combination free of coarse soiling? Clean if necessary.
Application Loading tips Select mobile units, baskets and inserts appropriate for the application. – Always load items in a way that all surfaces are exposed. This ensures that the items will be properly cleaned. – Tall, narrow pieces should be placed in the center of the baskets. This ensures good water coverage. – Mobile units with an adapter must engage correctly. – Engage inserts correctly into the module carts. – Do not nest any items inside other items. Keep each item separate.
Application Laboratory glassware (LG) Wide-necked glassware, such as wide necked erlenmeyer flasks and petri dishes or glassware with a cylindrical form, e.g. test tubes, can be cleaned inside and out with the rotating spray arm. General glassware, such as beakers, conical flasks, petri dishes, test tubes, etc. can be arranged in full size, half or quarter inserts in the higher or lower levels. Mobile injector units are available for direct injection spraying of narrow necked flasks, pipettes, etc.
Application Transfer cart for loading and unloading the machine ,When a disinfection process is being carried out according to national standards, the contaminated surfaces of the cart must be disinfected with a spray in accordance with national health and safety regulations, after the machine has been loaded. The transfer cart legs are height adjustable. Adjust the height so that the opened door of the lab glassware washer is held under the sidewise latches of the transfer cart.
Application ^ Push the transfer cart, as far as it will go, under the open door of the lab glassware washer. ^ Direct the mobile unit into the latches on the transfer cart using both hooks. ^ Lock the wheels. ^ To lift the mobile unit onto the door, step on the foot pedal of the transfer cart. ^ To lower the mobile unit, step all the way down on the foot pedal. ^ When the program is finished, back the transfer cart against the lab washer. The lab washer door must hook under the sideway latches.

Every 12-18 months: ^ Select operating level "B".
Effects of Processing Chemicals General information Effects Action Damage to elastomer (seals and hoses) or plastic components of the lab washer may cause the materials to swell, shrink, harden or become brittle, possibly causing cracks to form in the materials. This will impair their function, which will generally lead to leaks. – Find and correct the causes of the damage. See "Connected processing chemicals", "Soiling" and "Reactions between processing chemicals and soils" for more information.
Effects of Processing Chemicals Connected processing chemicals Effects Action The ingredients of the processing – Use only those processing chemicals recommended by Miele. chemicals have a considerable effect on the durability and functionality (feed – Perform regular visual inspections of performance) of the metering systems. the metering system. The metering systems (feed hoses and – Regularly check the feed pump) are designed for a specific type performance of the metering system.
Effects of Processing Chemicals Connected processing chemicals Effects Action The following processing chemicals can result in excessive foaming: – cleaning and rinsing agents that contain tensides, – emulsifiers. The foaming can occur: – in the program block in which the processing chemical is added, – in the subsequent program block due to carry-over, – in the case of rinsing agents, in the subsequent program due to carry-over. – The process parameters of the wash program, e.g.
Effects of Processing Chemicals Soiling Effects Action The following substances can damage the elastomer components (hoses and seals) and, in some cases, the plastic components of the lab washer: – oils, waxes, aromatic and unsaturated hydrocarbons, – softeners, – cosmetics, hygiene and skin care products such as creams (analysis and filling sections). – Retrofit the lab washer with more grease-resistant elastomers.
Effects of Processing Chemicals Reactions between processing chemicals and soils Effects Action Natural oils and greases can be saponified with alkaline processing chemicals. This may cause a lot of foaming. – Use the program OIL (if available). – Use the special program with emulsifier (neutral pH) metering for pre-rinsing. – Taking the specific application into account, add an antifoaming agent, one without silicone oils if possible.
