Contents

This machine conforms to current

safety requirements. Inappropriate

use can however lead to personal

injury and property damage. Read

the operating instructions carefully

before starting to use this machine.

Keep these instructions in a safe

place, and make them available to

future users.

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 might be dangerous.

The programs are designed for

laboratory glassware which are

declared reprocessable. Regard the

information from the glassware

manufacturer.

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 followin

notes, to maintain safe procedures.

The machine should be

commissioned and then

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 of or inadequacy of

an effective grounding system (e.g.

electric shock).

A damaged machine is dangerous.

Turn off the machine immediately at

the main 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 solvent, as the danger of

an explosion exists. The manufacturer’s

safety conditions must be observed

with all chemical agents.

,Wear protective gloves and

goggles.

The water in the machine must not

be used as drinking water.

Do not sit or lean on the open door

or rest objects on it. This could

cause the machine to tip and be

damaged or cause an injury.

Be careful when sorting items with

sharp pointed ends. Position them

in the machine that you do not hurt

yourself or create 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 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.

After drying with the TA drying unit

open the door to allow the items

and inserts to cool.

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.

Never clean near the machine with

a water or a high pressure hose.

Before servicing, disconnect the

power supply by either removing

the fuse, unplugging the unit or

manually "tripping" the circuit breaker.

IMPORTANT SAFETY INSTRUCTIONS

The followin points should be

observed to assist in maintainin

quality standards, for critical lab

lassware, to protect patients, and to

avoid dama e to the loads bein

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

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.

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

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.

Ensure that solutions or steam

containing hydrochloric acid do not

come into contact with the steel outer

casing of the machine to avoid any

corrosion damage.

Please follow the advice on

installation in these instructions

and the separate Installation

Instructions.

Usin accessories

Only specific additional equipment

made by Miele should be

connected to this machine. Consult the

Miele Professional Group on the type

and application of such equipment.

Disposal of an old appliance

When discarding a lab washer,

disconnect it from the power

supply, remove the door to the wash

cabinet and cut off the power cord. For

environmental and safety reasons

ensure the machine is completely

drained of any residue water and

cleaning agent. (Observe safety

regulations and wear safety goggles

and gloves). Make the door lock

inoperative, so that children cannot

accidentally shut themselves in. Make

appropriate arrangements for the safe

disposal of the machine.

If the machine contains a tank system,

remove the water from the tank before

disposing of the machine.

The manufacturer cannot be held

responsible for any damage caused

through non-observance of these

Warning and Safety Instructions.
