When using this machine regard

the high temperatures and be especially careful not to scald or burn yourself. When opening the door bypassing the electrical lock, a danger of burning, scalding or corrosion exists. Let baskets and inserts cool before touching them. Any water which may remain in containers will be very hot and must be emptied into the wash cabinet.

IMPORTANT SAFETY INSTRUCTIONS

The following points should be observed to assist in maintaining quality standards, for critical lab glassware, to protect patients, and to avoid damage to the loads being cleaned.

If the cleaning result is subject to

particularly stringent requirements (e.g. chemical analysis, specialized process), a regular quality control test should be carried out by the user to ensure that required standards of cleanliness are being achieved.

If toxic or chemical substances are

possible in the wash water regard the higher risk when interrupting a wash cycle and opening the door. Always check the seal of the door and the function of the steam condensator.

Use only Miele approved cleaning

agents with this machine. Use of unsuitable cleaning agents could adversely affect the components of the machine. Damages resulting from using unsuitable cleaning agents are not covered by the warranty.

Pre-treating (e.g. with cleaning

agents), certain soiling and cleaning agents with a chemical interaction, can cause foam. For pre-treatment and / or cleaning only use low-sudsing detergents and disinfecting agents which have been approved by Miele. Suds can have an adverse effect on the cleaning process.

When a chemical additive is

recommended, the manufacturer of the machine takes no responsibility for the effect of the chemical on the material of the items being cleaned. Please be aware that changes in formulation, storage conditions, concentration etc, which may not be publicized by the chemical producer, can have a negative effect on the cleaning result.

When using cleaning agents and

specialized products it is essential that the manufacturer’s instructions are followed. Only use the product for the application described by the manufacturer to avoid any material damage or the occurrence of strong chemical reactions.

The machine must only be

operated with water and the recommended cleaning agents. Organic solvents must not be used in the machine, as there is the danger under certain circumstances of explosion. Although this is not the case with all organic solvents, other problems could arise with their use, for example damage to rubber and synthetic materials.

IMPORTANT SAFETY INSTRUCTIONS

Opening and closing the door

Electric door lock

The machine is equipped with an electric door lock.

The door can only be opened if:

the machine is connected to the

–

electrical supply, the ON/OFF button I-0 is pressed,

–

and no wash program is running.

–

Opening the door

Press the 5 door button, grasp the

door handle and pull open the door.

Do not touch the heating

elements during or directly after the end of a program, you could burn yourself. They remain hot for some time after the end of the program.

To close the door

Lift the door upwards and push until it clicks shut.

To open the door with the emergency release

The emergency release should only be used when the door cannot be opened normally, e.g. in the case of a power failure.

Turn the machine off with I-0.

^ Reach up behind the service panel,

located at the bottom of the machine, and pull the ring of the emergency release downwards.

Do not use the emergency release when excessive temperatures have been reached in the cabinet. Danger of pressure wave release. Allow time for cooling.

Water softener

Before using the machine for the first time, the water softener should be programmed. The water needs to be softened to avoid calcium deposit buildup on the items being cleaned and in the machine itself.

To ensure a steady supply of soft water:

1. Make sure the water softener is programmed correctly.

2. The salt reservoir must be filled with reactivation salt.

If the water hardness is below 70

–

ppm (4 gr/gal) the reservoir does not need to be filled. Once the machine has been set accordingly the reactivation will no longer occur and the salt refill warning will not appear.

The machine is factory set to a water hardness level of 340 ppm (19 gr/gal).

Your local water authority will advise you of the water hardness in your area.

For future servicing it is useful to make a note of your water hardness level.

Enter the local water hardness level

here:

ppm

For fluctuating levels (e.g. 140 to 310 ppm) set the water softener to the highest setting (in this example to 310 ppm).

Important: The built-in water softener has settings from 18 ppm to 1080 ppm.

Water softener

Setting the water softener

To program the water softener, go to the REACTIVATE menu.

After calling up the REACTIVATE menu the following appears in the display:

OPERATING INFORMATION REACTIVATE HARDNESS SETTING IN >°D < WATER HARDNESS 19 SOFTENER CAPACITY 210 L OF 210 L

You can see how much capacity the softener had left until it next needs to be reactivated.

Water softener

Filling the salt reservoir

Only special, coarse-grained reactivation salt* should be used in this machine.

*Available from Miele’s Professional Customer Service Department. Please see back page for more information.

Do not use other types of salt, e.g. table salt, agricultural or gritting salt. These could contain components which are insoluble in water and could damage the water softener. If in doubt, consult Miele’s Professional Department.

The salt reservoir holds approx. 2.5 kg of salt.

Inadvertently filling the salt reservoir with detergent will damage the water softener. Before filling, make sure that you are using reactivation salt.

Place the funnel provided in place.

^ ^ Carefully fill the reservoir with salt.

Displaced water will run out as it is being filled.

^ Wipe any residual salt off the screw

threads on the socket.

^ Screw the cap on firmly. ^ Immediately after this step: Run the

"REMOVE SALT" program to remove any traces of salt from the cabinet.

Remove the bottom basket from the machine.

Unscrew the salt reservoir cap.

Before filling the salt reservoir with reactivation salt for the first time fill it with approx. 2.5 liters of water.

Note: There may be a delay before the "REMOVE SALT" program starts due to the reactivation of the water softener.

Salt indicator

Replenish the reactivation salt when the message ADD SALT is displayed.

Reactivation takes place automatically during a program. During this process the message REACTIVATION is displayed.

Water softener

Automatic mobile unit recognition (AWK)

In operating level C the optional Automatic mobile unit recognition (AWK) feature 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 be matched up.

^ Each mobile unit must be coded

before being used for the first time. See "Coding the mobile unit".

^ The wash program through which the

mobile unit is coded has to be assigned to the relevant program place (operating level D, see the "System function - Selector Organization" section in the Programming Manual).

Mobile unit coding

The AWK assigns a program 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 program available for a coded mobile unit is the one assigned to the corresponding program place.

After a coded mobile unit has been put in the machine and the door is closed, the control unit selects the allocated program. Press 6 to start the program.

Coding is affected through 5 Bits: – Bit 1 through 4 define the mobile unit

code,

– Bit 5 serves as a control (Parity-Bit).

Important!

Before starting the program with the "Start" button 6, check if the program needed for this mobile unit is displayed. Insufficient wash results may occur! Always check that programs for mobile units with AWK (on fixed program places) are not exchanged.
