notes to maintain safe procedures.

The machine should be

commissioned and maintained only by a Miele Service Technician. Repairs by unqualified persons could be dangerous.

Do not install the machine in an area

where a danger of explosion or freezing may be present.

Be certain this labwasher is properly

installed and grounded by an authorized technician. To guarantee the electrical safety of this machine, continuity must exist between the machine and an effective grounding system. It is imperative that this basic safety requirement be met. If there is any doubt, have the electrical system checked by a qualified technician. The manufacturer cannot be held responsible for damage or injury caused by the lack, or inadequacy, of an effective grounding system (e.g. electric shock).

A damaged machine is dangerous.

Turn off the machine immediately at the power switch and call the Miele Service Department.

Personnel operating the machine

should be trained regularly. Children and untrained personnel must not be allowed access to the machine or its controls.

Mount on non-combustible floors

only!

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.

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. Carefully position these items in the machine, so that you will 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 and corrosion exist. Let mobile units, inserts and cleaned items 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 TA drying unit

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

IMPORTANT SAFETY INSTRUCTIONS

If the boiler has been programmed

to "BOILER READY", be particularly careful of hot water and steam when opening the door. Danger of burning or scalding. The water inlet pipe to the wash cabinet is located, as viewed from the unclean side, underneath the basket runner on the left hand side.

Steam heating is permissible up to a

pressure of 145 psi. This corresponds to a water steam temperature of 354°F (179 °C).

Never clean the machine or near its

vicinity with a water or high pressure hose.

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 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-treatments with cleaning agents

can create suds, as can certain rinsing agents. For pre-treatment and / or cleaning, only use low-sudsing detergents which have been approved by Miele. Suds can have an adverse effect on the cleaning process.

In critical applications where very

high 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 the Miele Applications Specialists.

IMPORTANT SAFETY INSTRUCTIONS

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 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".

When a chemical additive is

recommended, the manufacturer of the machine takes no responsibility for the effect of the chemical on the items being cleaned.

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,

solvents or corroding ferrous material, and in particular hydrochloric acid or chloride solutions to get into the wash cabinet. Similarly avoid any materials with a corrosive effect. The presence in compounds of any solvents should be minimal, (especially those in hazard class A1).

To avoid any corrosion damage

ensure that solutions or steam containing hydrochloric acid do not come in contact with the stainless steel casing of the machine.

Please follow the installation advice

in these instructions and the separate Installation Instructions.

IMPORTANT SAFETY INSTRUCTIONS

Using accessories

Only genuine, Miele parts and

accessories should be used with this machine, including Miele mobile units, baskets and inserts.

Adequate cleaning results cannot

be guaranteed when non-Miele accessories are used, or when Miele accessories are altered. Damages resulting from the use of unsuitable accessories are not covered by the warranty.

Please note the following symbols on the machine:

Caution : See the Operating Instructions!

Caution : Danger of electric shock!

Disposal of an old machine

When discarding a lab washer,

disconnect it from the power supply and cut off the power cord. The old machine may be contaminated by blood or other body fluids and must be disinfected before disposal. For environmental and safety reasons ensure the machine is completely drained of any residual water and cleaning agent. (Observe safety regulations and wear safety goggles and gloves). Make the door lock inoperative or remove the door completely, so that children cannot accidentally shut themselves in. Make appropriate arrangements for the safe disposal of the machine. Machines with a tank system: remove the water from the tank before disposing the machine.

–

been correctly completed.

– the "Door locking" function is active

(see "Machine function - Door locking" in the "Programming Manual").

Opening the door

Press the 5 door button, hold the

door handle and open the door.

Do not touch the heating

elements (under the wide area filter) during or directly after the end of a program, you could burn yourself.

If the boiler has been programmed to "BOILER READY", be particularly careful of hot water and steam when opening the door. Danger of burning or scalding. The water inlet pipe to the wash cabinet is located, as viewed from the unclean side, underneath the basket runner on the left hand side.

To close the door

^ Lift the door upwards and push until

it clicks shut.

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".

^ The wash program through which the

mobile unit is coded has to be assigned to the relevant program place.

Program place changes, see the "System function - Selector switch organization" section in the Programming Manual.

Mobile unit coding

The automatic mobile unit recognition feature 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.

When a coded mobile unit is inserted in the machine and the door closes, the automatic mobile unit recognition selects the assigned program. Be sure no small items connect to the magnetic strip.

^ Press 6 to start the program.

Important!

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

The coding is made up of 5 bits:

–

Bits 1 to 4 define the mobile unit code,

–

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

Bit 6 controls the volume of water intake and the circulation pump for mobile units with side coupling. This setting cannot be changed! Mobile units without side coupling are coded with tracks which do not contain Bit 6!

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 automatic recognition (AWK) proceed as follows:

^ Unscrew the track with an AWK (allen

wrench) and remove it from the retainer.

The coded total must be an even number. Bit 6 is not included in this calculation.

If the coded total equals an odd number the message CHECK MOBILE UNIT RECOGNITION will appear. If the mobile unit code equals 0, the message NO MOBILE UNIT RECOGNITION will appear. In both cases the program cannot be started. The mobile unit recognition must be reset.

Remove the magnetic strip from the track.
