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.

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.

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.

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.

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!

After work on the mains water

supply, the water supply line to the machine must be vented. Machine components may otherwise be damaged.

Electric door lock

The machine is equipped with an electric door lock.

The door can only be opened when:

the machine is connected to the

–

electrical supply,

the machine is turned on with the s

–

button, and

no wash or disinfection program is

–

running.

Opening the door

^ Press the a door button, and

holding onto the door grip open the door.

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.

Opening and closing the door

When opening the door

bypassing the lock, a danger of burning, scalding, corrosion and inhalation of toxic fumes exist.

Do not touch the heating element if you are interrupting a program by opening the door. Danger of burns.

Disconnect the machine from the

electrical supply.

Closing the door

Lift the door upwards and push until it clicks shut.

Opening the door with the emergency release

The emergency release should only be used when the door cannot be opened normally, e.g. in the case of a power failure. Caution with DESIN programs – see Important Safety Instructions.

Remove the service panel and pull the ring of the emergency door release down.

If there is a lot of hot water in the machine at the time the emergency release is used and the door is not closed quickly, water will be allowed to escape from the machine. Danger of scalding and burns!

Water softener

For good cleaning results, the machine requires soft (calcium poor) water. If the mains water is hard, white deposits will form on the load and the walls of the rinsing chamber. Softening is required if the hardness of the mains water exceeds 4 °d (4 gr/gal). This takes place automatically in the built-in softener.

The softener requires regeneration

–

salt.

The machine must be programmed

–

exactly to the hardness of your mains water supply.

– Information on the exact hardness of

the mains water can be obtained from your local water authority.

The machine is set at the factory for a water hardness level of 19 °d (19 gr/gal).

If the water supply is harder or softer than the factory setting (including below 4 °d [4 gr/gal (0.7 mmol/L)], the setting will need to be changed in the electronic control.

Your local water authority will advise you on the water hardness in your area.

Where the water hardness fluctuates e.g. between8-17°d(8-18gr/gal), always program the machine to the higher value, 17 °d (18 gr/gal) in this example.

The water softener can be set from 1

- 60 °d (1 - 63 gr/gal).

If there is a fault, it will be helpful to know the water hardness of the local water supply.

Enter the local water hardness level:

Water softener

Setting the water softener

The water softener must be set by the service technician after installing the machine to reactivate the water softener according to the local water hardness level. See Programming Manual "Operation information Reactivation".

Refill salt indicator

The display shows Refill salt, when the salt must be refilled.

The

Reactivation of the water softener

is completed automatically during a program.

Reactivation the water softener

Only special, coarse-grained reactivation salt* should be used in this machine.

*Available from Miele’s Professional Customer Service Department. Please see back page for more information.

Do not use other types of salt,

e.g. table salt, agricultural or gritting salt. These could contain components which are insoluble in water and could damage the water softener. If in doubt, consult Miele’s Professional Department.

The salt reservoir holds approx. 4.4 lb (2 kg) of salt.

Inadvertently filling the salt reservoir with detergent will damage the water softener. Before filling, make sure that you are using reactivation salt.

Remove the lower basket.

Unscrew the cap.

Before filling the salt container for the first time, fill it will approximately 2.5 liters of water to allow the salt to dissolve. After the first use there will always be enough water in the salt container.

Water softener

Immediately after this step, start the

REMOVE SALT program, to remove

any traces of salt from the inside of the lab washer.

In operating level C, you must start the reactivation using the context menu. To do so:

Open the context menu.

- Select the menu item

REMOVE SALT and confirm with

OK.

Place the funnel provided in place.

^ Carefully fill the reservoir with the

reactivation salt.

Some displaced water will run out - this is normal.

Wipe any residual salt off the screw threads and seal of the reservoir.

Screw the cap on securely.

There may be a delay of a few minutes before the

REMOVE SALT

program starts due to the reactivation of the water softener.

Automatic mobile unit recognition

The automatic mobile unit recognition feature assigns a program place to a mobile unit. For this to work, the mobile units must be coded with a magnetic strip (with a bit combination). The ML/2 magnetic strip can be purchased separately.

In operating level C, each coded mobile unit is assigned to the corresponding program place.

When a coded unit is inserted into the machine and the lab washer door closes, the automatic mobile unit recognition selects the assigned program.

See the separate "Programming Manual" for information on how to code a mobile unit and assign programs.

Make sure that no metallic parts

or pieces are stuck to the magnetic strip or its underside. Attached metallic objects can cause the coding to be misread or unreadable.

The magnetic strips of the PG 8535/8536 lab washers are gray

Spray arm monitoring

The processing result depends on the rinsing and flushing of all surfaces and hollow spaces of the lab ware with wash water. One top and one bottom spray arm in the appliance distribute the wash water in the wash cabinet.

When

Spray arm monitoring is

activated, the system will check whether the speeds of the spray arms are maintained within predefined limit values.

Mobile unit

Mobile units can be fitted with one or several spray arms. They must be equipped with magnets for the speed monitoring to be functional.

Spray arm monitoring will only function if the type of mobile unit is coded with a magnetic strip (see the "Programming Manual - Coding a mobile unit").

Top and bottom baskets

For the PG 8535 / 8536 lab washers, combinations of top and bottom baskets may be used in addition to the mobile units.

The top baskets can be also fitted with spray arms using speed monitoring. This does not require a magnetic strip.

As per factory setting, spray arm monitoring for the top basket is deactivated.

This setting may be kept if only top baskets without spray arm are used.

If top baskets with and without spray arms are used and spray arm monitoring for the top basket is activated, the following message will appear prior to starting the program:

Basket with a spray arm?

This question can be answered with Yes or No.

Miele Technical Service can deactivate this query if only top baskets with spray arms are used.

Use

The lab washer can be fitted with a variety of mobile units, baskets and inserts, depending on the cleaning application desired.

Effects of Processing Chemicals

General information

Effects Action

Damage to elastomer (seals and hoses) or plastic components of the lab washer may cause the materials to swell, shrink, harden or become brittle, possibly causing cracks to form in the materials. This will impair their function, which will generally lead to leaks.

Strong foaming during the program prevents proper cleaning and rinsing of the load. Foam escaping from the wash compartment can result in damage to the lab washer. If foaming occurs, the cleaning process is not standardized and not validated.

Stainless steel corrosion in the wash compartment and/or accessories may appear in various ways:

– rust formation (red spots / stains), –

black spots / stains,

–

white spots / stains (smooth surface is slightly corroded).

Corrosion that forms holes can result in leaks in the lab washer. Depending on the application, the corrosion may impair the cleaning and rinsing results (laboratory analysis) or cause corrosion of the load (stainless steel).

Find and correct the causes of the

–

damage.

See "Connected processing chemicals", "Soiling" and "Reactions between processing chemicals and soils" for more information.

Find and correct the cause of the

Effects of Processing Chemicals

Connected processing chemicals

Effects Action

The ingredients of the processing chemicals have a considerable effect on the durability and functionality (feed performance) of the metering systems. The metering systems (feed hoses and pump) are designed for a specific type of processing chemicals.

General categories:

alkaline to neutral pH products,

–

acid to neutral pH products,

–

hydrogen peroxide.

–

The processing chemicals can damage the elastomer and plastic components of the lab washer and its accessories.

Hydrogen peroxide can release large quantities of oxygen.

Use only those processing chemicals

–

recommended by Miele. Consult a Miele Applications Specialist.

Perform regular visual inspections of

–

the metering system. Regularly check the feed

–

performance of the metering system.

– Use only those processing chemicals

recommended by Miele. Consult a Miele Applications Specialist.

– Perform regular visual inspections of

all visible elastomer and plastic components.

– Use only tested processes such as

OXIVARIO or OXIVARIO PLUS (if available).

–

In the case of hydrogen peroxide, the washing temperature should be below 158 °F (70 °C).

Consult a Miele Applications Specialist.

Effects of Processing Chemicals

Connected processing chemicals

Effects Action

The following processing chemicals can result in excessive foaming:

tenside cleaners containing

–

detergent and rinse aid.

The foaming can occur:

in the program block in which the

–

processing chemical is added, in the subsequent program block

–

due to carry-over, in the case of rinsing agents, in the

–

subsequent program due to carry-over.

Antifoaming agents, particularly silicone-based antifoaming agents, can cause the following:

– deposits in the wash compartment, – deposits on the wash load, – damage to the elastomer and plastic

components of the lab washer,

– attack certain plastics (e.g.

polycarbonates, plexiglass, etc.) in the wash load.

The process parameters of the wash

–

program, e.g. metering temperature, metering concentration, etc. must be set so that the overall process creates little or no foam.

Observe the instructions of the

–

manufacturer of the processing chemicals.

– Use antifoaming agents only in

exceptional cases or when they are absolutely necessary for the process.

– Periodic cleaning of the wash

compartment and accessories without a load and without an antifoaming agent using the ORGANICA program (if available).

Consult a Miele Applications Specialist.

Effects of Processing Chemicals

Effects Action

The following substances can damage the elastomer components (hoses and seals) and, in some cases, the plastic components of the lab washer:

oils, waxes, aromatic and

–

unsaturated hydrocarbons, softeners,

–

cosmetics, hygiene and skin care

–

products such as creams (analysis and filling sections).

The following substances can cause excessive foaming during washing and rinsing:

– agents such as disinfection agents,

dish detergents, etc.

– reagents for analysis, e.g. for

microtitration plates,

– cosmetics, hygiene and skin care

products such as creams (analysis and filling sections).

–

–

grease-resistant elastomers. Depending on what the lab washer is

–

used for, periodically wipe the lower door seal with a lint-free cloth or sponge. Clean the wash compartment and accessories without a load using the ORGANICA program.

To process the load, use the

–

program "OIL" (if available) or use the special program with metering of tenside cleaners..

– First rinse the load with a sufficient

quantity of water.

– Select a wash program with one or

more short pre-rinses with cold or warm water.

– Taking the specific application into

account, add an antifoaming agent, one without silicone oils if possible.

The following substances can cause corrosion of the stainless steel in the wash compartment and accessories:

–

hydrochloric acid,

–

other substances that contain chloride, e.g. sodium chloride, etc.

–

conc. sulphuric acid,

–

First rinse the load with a sufficient quantity of water.

–

Let the load drip dry before putting it on the carts, baskets and inserts and placing in the lab washer.

Effects of Processing Chemicals

Reactions between processing chemicals and soils

Effects Action

Natural oils and greases can be saponified with alkaline processing chemicals. This may cause a lot of foaming.

In combination with alkaline processing chemicals, loads with soiling that contains proteins, e.g. blood, can cause excessive foaming.

In combination with very acidic or alkaline processing chemicals, base metals such as aluminum, magnesium and zinc can release hydrogen (detonating gas).

Use the program OIL (if available).

–

Use the special program with dosing

–

of tenside cleaners (neutral pH) for pre-rinsing.

Taking the specific application into

–

account, add an antifoaming agent, one without silicone oils if possible.
