~This machine is not intended for any

purpose that is not indicated in the

operating instructions. Conversions,

modifications, and other unintended

uses are considered to be dangerous.

Follow the product manufacturer's

instructions. Miele will not be held liable

for damage caused by incorrect use of

any kind.

~The installation of this unit in non

stationary locations (e.g. ships) must be

performed by a qualified installer or

service agency in strict accordance

with national and local safety

regulations and standards.

Please pay attention to the following

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 appliance is properly

installed and grounded by an

authorized technician. To guarantee the

electrical safety of this appliance,

continuity must exist between the

appliance 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.

Do not use organic solvents as these

could cause an explosion. Wear

protective gloves and goggles. With all

chemical agents the manufacturer’s

safety conditions must be observed.

~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 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.

~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.

IMPORTANT SAFETY INSTRUCTIONS

~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.

~If toxic chemicals may be present in

the wash cabinet, beware of this risk

when interrupting a program and

opening the washer. The door seal and

steam condensor must always be

checked for soundness.

~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.

~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 and

damage to rubber and synthetic

materials. Follow the dosage

recommendations of the cleaning

agent’s manufacturer.

IMPORTANT SAFETY INSTRUCTIONS

~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.

~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.

~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.

~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 appliance

~When discarding a lab washer,

disconnect it from the power supply

and cut off the power cord.

The old appliance 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.
