Contents

This machine conforms to current

safety requirements. However,

inappropriate use can lead to

personal injury and property

damage. Read the operating

instructions carefully before using

this machine.

The manufacturer cannot be held

responsible for damage caused by

non-observance of these Important

Safety Instructions.

Use

This machine is designed for

commercial use and for

specialized applications only, as

described in these Operating

Instructions. Do not use for purposes

other than those for which it was

designed, as this could be dangerous.

Miele is not responsible for damages

caused by improper use.

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.

IMPORTANT SAFETY INSTRUCTIONS

Take care when handling liquids

such as detergents, neutralizing

agents, wetting agents and rinse aids.

These may contain irritant or corrosive

ingredients, acids or alkalis. Never use

any organic solvents, as the danger of

explosion exists. Wear protective

gloves and goggles. The

manufacturer’s safety conditions must

be observed at all times.

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 so that you do not hurt

yourself or create a danger for others.

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.

After drying with the TA drying unit

open the door to allow the items

and inserts to cool.

Do not touch the heating elements

(under the wide area filter) during

or directly after the end of a program,

you could burn yourself. They remain

hot for some time after the program

end.

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 near or

with a water or high pressure hose.

Before servicing, disconnect the

power supply by either removing

the fuse, unplugging the unit or

manually "tripping" the circuit breaker.

,Mount on non-combustible floors

only!

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.

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 which have

been approved by Miele. Suds can

have an adverse effect on the operation

of the machine.

After START has been pressed the

program must not be interrupted

by pressing the I-0 button. A program

should not be interrupted since the

result may be effected. Otherwise the

program must be repeated.

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 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.

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.

If the cleaning result is subject to

particularly stringent requirements

(e.g. chemical analysis, specialized

processes), a regular quality control

test should be carried out by the user to

ensure that the required standards of

cleanliness are being achieved.

The cleaning standard in the

routine use must be verified by the

user. The process should be checked

regularly using thermoelectric and

documented results.

IMPORTANT SAFETY INSTRUCTIONS

The mobile units and special

inserts should only be used for

their specific application.

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.

Using accessories

Only specific additional equipment

made by Miele should be

connected to this machine. Consult a

Miele Application Specialist on the type

and application of such equipment.

Only Miele mobile units, modules

and inserts should be used. If

equipment from another manufacturer

is used, Miele cannot ensure the

cleaning and disinfection results.

Damage or injury caused by this are

excluded from the warranty.

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.

Machines with a tank system: remove

the water from the tank before

disposing the machine.
