The installation of this unit in non

stationary locations must be performed by a qualified installer or service agency, in strict accordance with national and local safety regulations and standards.

IMPORTANT SAFETY INSTRUCTIONS

Take care when handling

processing chemicals (detergents, softeners, neutralizers, etc.). These may contain irritant or corrosive ingredients. Wear protective gloves and goggles. With all chemical agents the manufacturer’s safety conditions must be observed.

The lab washer is only designed to

operate with water and the recommended processing chemicals. The machine must NOT be operated with organic solvents or flammable liquids. This may cause an explosion or damage to rubber and plastic components, which in turn allows liquid substances to leak out.

Do not stand, sit or lean on the

opened machine door. This could cause the machine to tip over, resulting in injuries and damage.

Do not touch the heating elements

during or directly after the end of a program, burns could result. The elements remain hot for some time after the end of the program.

The water in the machine must not

be used as drinking water.

Be careful when sorting items with

sharp pointed ends. Position them in the machine that you do not hurt yourself or create a danger for other operators.

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 chemical burns exists. When disinfectants are used a danger of the inhalation of toxic fumes 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.

If toxic chemical substances can

form in the wash water during processing (e.g. aldehydes in the disinfection agent), the door seal and, if applicable, the function of the steam condensor must be checked regularly. In that case, opening the lab washer door during a program interruption can be dangerous.

If you are exposed to toxic vapors or

processing chemicals, consult the manufacturer's material safety data sheets for emergency procedures.

Always allow mobile units, modules,

inserts, and loads to cool before removing. Be sure to empty any water from concave items into the wash cabinet before removing.

After drying with the drying unit

open the door to allow the items and inserts to cool.

Never clean the machine, or in its

vicinity, with a water or a high pressure hose.

IMPORTANT SAFETY INSTRUCTIONS

Avoid inhaling powder products.

They can cause burning in the mouth and throat if swallowed, and can inhibit breathing.

Before servicing, disconnect the

power supply by either removing the fuse, unplugging the unit or manually "tripping" the circuit breaker.

Whenever work is conducted on the

tap water network, the water supply line to the washer must be cleared of air. Failure to do so can result in damage to the water softener.

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

For this type of cleaning, the

program must not be interrupted until completion. In other words, the On/Off Button must not be used. Interruptions should also be avoided for all other programs, such as during performance testing, because this can negatively affect the cleaning and rinsing results. After any interruption, the program should be restarted from the beginning.

Only use cleaning agents

formulated for special processes and approved by Miele for use with this machine. Use of unsuitable cleaning agents could adversely affect the components of the machine.

Use of a chemical disinfectant at

moderate temperatures (for example 149°F / 65°C or lower) do NOT fulfill the official requirements for disinfection pursuant to FDA regulations. Always note their specifications for handling, application conditions and efficacy. The operator is responsible for the use of any such thermo-chemical processes.

The process must be set so that no

foam escapes the wash compartment. Escaping foam jeopardizes the safe operation of the lab washer.

The process must be checked

regularly in order to detect any foaming.

In order to prevent damage to the

lab washer and any accessories through processing chemicals or dirt as well as any interaction between them, see "Effects of Processing Chemicals".

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.

IMPORTANT SAFETY INSTRUCTIONS

In critical applications where very

stringent requirements have to be met, it is strongly recommended that all the relevant factors for the process, such as cleaning agent, quality of water, etc. are discussed with a Miele Applications Specialist.

It is the responsibility of the operator

to routinely check that the required cleaning standards are being met. Therefore, results need to be regularly tested and documented, both thermo electrically and through inspection. For thermo chemical processes, additional testing is required using chemical or biological indicators.

The performance of the cycles was

tested using Neodisher products. The use of other products is not discouraged but may not yield identical results. Please be aware that changes in formulation, storage conditions, etc. which may not be publicized by the chemical manufacturer can have a negative effect on cleaning results. and are not the responsibility of the machine manufacturer.

The mobile units, baskets and

special inserts should only be used for their specific applications. Instruments with hollow parts must be flushed through with wash water.

Empty any containers or utensils

before arranging them in the machine.

Do not allow any remains of acids or

solvents, and in particular hydrochloric acid, chloride solutions or corroding ferrous material to get into the wash cabinet. Similarly avoid any materials with a corrosive effect. The presence in compounds of any solvents should be minimal.

To avoid corrosion damage ensure

that solutions or steam containing hydrochloric acid do not come into contact with the steel outer casing of the machine.

Please follow the advice on

installation in these instructions and the separate Installation Instructions.

Please note the following symbols on the machine:

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.

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

To obtain good cleaning results, the machine needs soft water. Hard tap water results in calcium deposits on the glassware and the machine. If your tap water hardness is above 4°d, the water should be softened. This takes place automatically in the unit's integrated water softener.

To ensure a steady supply of soft water:

The water softener must be filled with

–

reactivation salt.

The machine must be programmed

–

to correspond to the water hardness in your area. The local water authority will advise you of the water hardness in your area.

If the water hardness is below 70 ppm (4 gr/gal) the reservoir does not need to be filled.

The machine is factory set to a water hardness level of 340 ppm (18 gr/gal).

Setting the water softener

The water hardness must be programmed by Miele's Technical Service when the machine is commissioned. The water hardness is programmed in the Profitronic according to the Programming Manual (see "Operating information Reactivation").

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.

The default setting must be programmed to the local water hardness.

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

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

Enter the water hardness to have it available for service calls (if needed):

ppm

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.

Water softener

Place the funnel provided in place.

^ Carefully fill the reservoir with salt.

Some displaced water will run out - this is normal.

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.

Water softener

Wipe any residual salt off the screw

threads and seal of the reservoir.

^ Screw the cap on firmly.

^ Immediately after this step: Run the

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

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

Automatic mobile unit recognition (AWK)

In operating level C the AWK allocates a mobile unit with valid coding to a fixed program place. 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 electronic control unit) have to match each other.

Matching the coding and program place

^ Each mobile unit must be coded

before being used for the first time (see "Setting the mobile unit coding").

^ The wash program through which the

mobile unit is coded has to be assigned to the relevant program place (see the Programming Manual "System function - Selector Switch Organization").

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.

Make sure that no small metallic items (e.g. keys) stick to the magnetic strip or its underside. The coding might be not readable.

^ Press 6 to start the program.

Coding is affected through 5 Bits:

Important!

Before starting the program with the "Start" button 6, check if the program needed for the mobile unit is displayed. Insufficient wash results may occur!

Always check that programs for mobile units with automatic unit recognition (AWK) (on fixed program places) are not exchanged.

–

Bit 1 through 4 define the mobile unit code,

–

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

Automatic mobile unit recognition (AWK)

Mobile unit coding strip

15 different codes can be set. They are assigned to program places 1 to 15.

Under "System function - Selector switch organization" the matching programs have to be put into the first 15 program places.

Setting mobile unit coding

To set or alter the coding of a mobile unit with the AWK proceed as follows:

^ Unscrew the track with an Allen

wrench and remove from the retainer.

The coded total must be an even number.

If the coded total is an odd number, the message CHECK MOBILE UNIT RECOGNITION appears. If the mobile unit total equals 0, the message NO MOBILE UNIT RECOGNITION will appear. In neither case can the program be started and the mobile unit recognition function will have to be reset.

Remove the magnetic strip from the track.
