~
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.
4
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,
~

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.
6
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
~

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

,
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!
21
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.
22
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.
23
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.
24
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
25
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.
26
Use
The lab washer can be fitted with a variety of mobile units, baskets and inserts, depending on the cleaning application desired.
Loading the machine
Removing excess soils
Empty all containers before loading
^
them into the machine.
Ensure that no acid or solvent
,
residues, especially hydrochloric acid or chlorides get into the wash cabinet.
Check before cleaning
Are the items to clean correctly
sorted and connected?
Are the spray arms clean and can
they rotate freely?
Is the filter combination free of
coarse soiling?
Is the adapter to the water inlet in
place?
Are the spray arms correctly
connected?
Are the detergent and neutralizer
containers full?
Check after cleaning
– Check the cleaning results visually.
– Are the jets and connections
securely connected with the mobile unit / inserts?
Process validation
As a rule, it is the responsibility of the user to ensure that items cleaned in the machine meet the required standards.
27
Use
Loading tips
Select mobile units, baskets and inserts appropriate for the application.
Load the items to be washed so that
water can access all surfaces. This ensures that they are properly cleaned.
Do not place items to be cleaned
inside other pieces where they may be concealed.
Hollow vessels such as beakers,
measuring cylinders, flasks, etc. should be inverted and placed in the correct inserts so that water can flow in and out unrestricted. A cover net can be used to reduce the risk of movement during the wash process.
– Use a cover net (e.g. an A 6) or a
mesh tray for small items, to secure lightweight items and to prevent them from blocking the spray arms or being caught in the magnetic strip on the automatic mobile unit recognition system.
Deep based items should be placed at an angle to allow water to run off easily.
Tall, narrow pieces should be placed
in the center of the baskets. This ensures good water coverage.
Mobile units and baskets with an
adapter must engage correctly.
Engage inserts correctly into the
module carts.
The spray arms must not be blocked
by tall items or items which hang in their path. If necessary, manually rotate the arms to test.
Petri dishes and the similar should
be placed in the correct insert with the soiled side facing the center.
– Insert pipettes with the pointed end
downwards.
– Quarter inserts should be placed as
close to the middle of the unit as possible.
– Glassware should not stick out of the
door area.
,
Ensure that no acid or solvent residues, especially hydrochloric acid or chlorides, get inside the machine.

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
foaming. The process must be checked
regularly in order to detect any foaming.
See "Connected processing chemicals", "Soiling" and "Reactions between processing chemicals and soils" for more information.

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.
33
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.
34
Effects of Processing Chemicals
Soiling
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).
foaming substances in general, for instance tensides.
Retrofit the lab washer with more
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,
chromic acid,
iron particles.
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.
35
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.
Select a wash program with one or
more short pre-rinses with cold water.
– Observe the instructions of the
manufacturer of the processing chemicals.
36
Adding liquid detergents and neutralizers

be connected to a cold (coded blue) and a hot (coded red) water supply to a maximum temperature of 158 °F (70 °C). Connect the water intake hoses to the cold and hot water faucets. The steam condenser inlet hose (without waterproof connector) should be connected to the cold water supply, using the adapter supplied
If no hot water supply is available, the hot water inlet hose marked red should also be connected to a cold water supply by a y-adapter. For a DI-water connection (H2O pure), see next page.
^ Water valves with
hose thread are to be provided on site. They should be easily accessible so the water supply can be turned off if necessary.
^ The inlet hoses are 5 ½ feet (1.7 m)
long, terminating in a female hose thread. The water inlet
filters in the threads must not be removed.
^
Large surface area filters are enclosed in the kit supplied with the machine. Install these filters between the water valve and the water inlet hose (see illustration in "Cleaning the water inlet filters"). The large surface area filter for DI water is made from stainless steel and can be recognized by its matte surface.

DI-Water connection (pressure resistant) (over 9 to 145 psi)
The machine comes with a standard connection for a pressurized DI system. The recommended water pressure (flow rate) is 25 - 60 psi however, water pressure of 9 - 147 psi is acceptable.
The DI pressure-tested hose (marked

thread must be connected to the on-site water valve for DI purified water.
If the machine will not be
,
connected to DI water, the cleaning and disinfection programs must be changed by Miele Technical Service. The intake hose stays at the rear of the machine.
DI water connection (pressureless)
1.25 - 9 psi (optional)
62
For connection to 1.25 - 9 psi water pressure the machine must be converted if it was not ordered from the factory as a special model. A feed pump must be installed by Miele's Technical Service Dept.
The discharge nipple of the DI water container (pressureless) must be at least at the same height as the machine's upper edge.
Drain
The drain system incorporates a
non-return valve which will prevent dirty water from flowing back into the machine via the drain hose.
The machine should be connected to
a dedicated standpipe. If separate drainage is not available, contact your Miele application specialist for professional advice. The standpipe should be situated between 1 ft. (0.3 m) and 3 ft. (1 m) above the floor. If it is lower than (1 ft.) 0.3 m, water may siphon out of the machine during use. The drain must be able to take a minimum flow of 4 gal/min (16 l/min).
– The flexible drain hose is approx. 5
ft. (1.4 m) long and has an internal diameter of 3/4" (22 mm). It should not be shortened. Hose clamps are supplied for securing it in position.
Plumbing
A longer drain hose (up to 12 ft./4m long) is available to order from Miele.
The overall length of the drain hose must not exceed 12 ft. (4 m).
As standard, the machine drain water will reach temperatures greater than 160°F. In order to meet local building codes Miele offers an optional drain temperature reduction kit. Please contact Miele for details.
