IMPORTANT SAFETY INSTRUCTIONS

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.

Keep these instructions in a safe place and pass them on to any future user.

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.

This machine in intended for indoor use only.

Please pay attention to the following notes to maintain safe procedures.

The machine should be commissioned and maintained only by a Miele Service Technician. Good laboratory guidelines should be followed. 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.

A damaged or leaking machine is dangerous. Disconnect the machine from the power supply immediately and contact Miele.

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

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. Wear protective gloves and goggles. The manufacturer’s safety conditions must be observed at all times.

IMPORTANT SAFETY INSTRUCTIONS

The lab washer is only designed to operate with water and the appropriate 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.

The water in the machine must not be used as drinking water.

Do not sit or lean on an open door. The machine could tip and be damaged or cause injury.

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.

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 condenser must be checked regularly. In this event, opening the door of the lab washer during a program interruption is particularly hazardous.

If you are exposed to toxic vapors or processing chemicals, consult the manufacturer's material safety data sheets for emergency procedures.

Mobile units, baskets, inserts and the load itself must be allowed to cool before removal. The dispensing parts should also be drained of any residual water.

After drying with the drying unit, open the door to allow the load, mobile unit, baskets and inserts to cool down.

Do not touch the heating element if you open the door at the end of the program. You may suffer burns even several minutes after the program has ended.

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 and to avoid damage to the loads being cleaned.

Only authorized persons may interrupt a program, and only in exceptional cases.

Use of a chemical disinfectant at moderate temperatures (for example 149°F / 65°C or lower) do NOT fulfill the official requirements for disinfection pursuant to FDA regulations. Always note their specifications for handling, application conditions and efficacy. The operator is responsible for the use of any such thermo-chemical processes.

If the machine is being used for disinfection ordered by the authorities, the steam condenser and its connections to the rinsing chamber and outlet discharge must be disinfected before any repair or exchange.

Only use process chemicals that are approved by their manufacturer for the application involved. Any negative effects on labware and the washer itself are the liability of the chemical manufacturer.

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.

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.

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

If the cleaning result is subject to particularly stringent requirements (e.g. chemical analysis), a regular quality control test should be carried out by the user to ensure that the required standards of cleanliness 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, 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.

After work on the mains water supply, the water supply line to the machine must be vented.

Machine components may otherwise be damaged.

Please follow the installation advice in these instructions and the separate Installation Instructions.

Using accessories

Only Miele accessories 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 results. Damage or injury caused by this are excluded from the warranty.

Please note the following symbols on the machine:

Caution : See the Operating

Instructions!

Caution : Danger of electric shock!

IMPORTANT SAFETY INSTRUCTIONS

Disposal of an old appliance

When discarding an Industrial cleaner, disconnect it from the power supply 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 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.
