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.

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
~
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

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.

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

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.

Effects of Processing Chemicals
General information
EffectsAction
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
EffectsAction
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
EffectsAction
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
EffectsAction
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
EffectsAction
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.

Water inlet
Water in the machine is not
,
suitable for drinking.
The machine must be connected to
^
the water supply in accordance with
local and national regulations.
The washer is constructed so it may
^
be connected to a supply without an
extra non-return valve, unless
required by code.
Water supply pressure
^
Hot + Cold water connection =
min. 12 psi - max.145 psi
DI water connection =
min. 9 psi - max. 145 psi
^ Recommended water pressure
Hot + Cold water connection =
over 37 psi - max.145 psi
DI water connection =
over 22 psi - max. 145 psi
to avoid long intake times
^
If the water pressure is not in the
range of 12 to 145 psi, contact
Miele's Technical Support. The
display might show "CHECK WATER
INTAKE".
Plumbing
The machine is supplied standard to
^

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
