specialized applications. Only use

the appliance for its intended

purpose. Any other use, conversion

or modification is dangerous. The

manufacturer cannot be held

responsible for damages caused by

improper use of this machine.

This appliance complies with current

safety requirements. Improper use of

the appliance can lead to personal

injury and material damage.

Read all instructions before installing

or using this appliance.

Keep these operating instructions in

a safe place and pass them on to

any future user.

Installation an Service

The machine should only be

installed, maintained and repaired

by a Miele authorized service

technician. Repairs by unqualified

persons could be dangerous.

Do not install the machine in an

area where a danger of explosion

or of freezing may be present.

This equipment is not designed for

maritime use or for use in mobile

installations, such as caravans or

aircraft. However, under certain

conditions it may be possible for an

installation in these applications. Please

contact the nearest Miele dealer or the

Miele Technical Service Department

with specific requirements.

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 of

the house 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 .

A damaged machine is dangerous.

Turn off the machine at the main

power supply immediately and call the

Miele Technical Service Department.

Before servicing, disconnect the

power supply by either removing

the fuse or "tripping" the circuit breaker.

IMPORTANT SAFETY INSTRUCTIONS

Use

Personnel operating the machine

should be trained regularly.

Children and untrained personnel must

not be allowed access to the machine

or its controls.

BURN AND SCALD HAZARD

This washer reaches very high

temperatures. Take care when

unloading the unit. 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.

BURN HAZARD

The heating elements become

extremely hot during use. Do not touch

the heating elements during or directly

after the end of a program.

Take care when handling liquids

such as detergents, wetting agents

or neutralizing agents. These may

contain irritant or corrosive ingredients.

Do not use an organic solvent in this

washer, as an explosion may occur.

Wear protective gloves and goggles.

The manufacturer’s safety conditions

must be observed for all chemical

agents.

Avoid inhaling powdered

detergent. If swallowed, they can

cause burning in the mouth and throat,

or inhibit breathing.

Be careful when sorting items with

sharp pointed ends. If possible,

place the pointed end downwards.

The water in the machine must not

be used as drinking water.

Do not sit or lean on the open door.

Injury or machine damage could

result.

Never clean the machine or its

vicinity with a water hose or a high

pressure hose.

IMPORTANT SAFETY INSTRUCTIONS

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.

Pre-treatments with detergents 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.

Where a chemical additive is

recommended on technical

application grounds (for example, with

a cleaning agent), this does not imply

that the manufacturer of the machine

takes responsibility for the effect of the

chemical on the material of the items

being cleaned. Please be aware that

changes in formulation, storage

conditions, etc, which may not be

published 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 is designed only for

operation with water and additive

cleaning agents. Organic solvents must

not be used in the machine. An

explosion or machine corrosion could

occur with the use of organic solvents.

In critical applications where very

high requirements must 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 Technical

Service Department.

IMPORTANT SAFETY INSTRUCTIONS

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 are

being achieved.

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, particularly

hydrochloric acid or chloride solutions,

to get into the wash cabinet. The

presence of any solvents should be

minimized (especially those in hazard

class A1).

To prevent corrosion damage,

ensure that solutions or steam

containing hydrochloric acid do not

come into contact with the steel outer

casing of the machine.

Accessories

Only genuine Miele parts or

accessories should be used with

the G 7804 Laboratory Glassware

washer. The performance and safety of

non-genuine parts or accessories

cannot be guaranteed, and use of such

parts or items may void the machine

warranty. If you have specific questions

about machine options or accessories,

please call Miele.

Disposal of an appliance

When discarding an old laboratory

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 residual

water and cleaning agent. (Observe

safety regulations and wear safety

goggles and gloves). Make appropriate

arrangements for the safe disposal of

the machine.
