~
water network, the water supply line to
the lab washer must be cleared of air.
Failure to do so can result in damage to
the laboratory glassware washer.
The following points should be
observed to assist in maintaining
quality standards for critical labware
and to avoid damage to the loads
being cleaned.
For this type of cleaning, the
~
program must not be interrupted until
completion. Interruptions should also
be avoided for all other programs, such
as during performance testing,
because this can negatively affect the
cleaning and rinsing results. After any
interruption, the program should be
restarted from the beginning.
Only use cleaning agents
~
formulated for special processes and
approved by Miele for use with this lab
washer. Use of unsuitable cleaning
agents could adversely affect the

If the water supply is harder or softer
than the factory setting (including
below 4 gr/gal or 70 ppm), the setting
will need to be changed. See "Setting
the water softener".
In order to function properly, the
–
water softener requires a supply of
reactivation salt.
– The cleaner must be correctly
programmed to match the hardness
of the tap water supply.
– Your local water authority can
provide information about the
hardness of the tap water in your
area.
If the water hardness is known to
fluctuate, always program for the
highest value.
The built-in water softener can be
programmed at settings from
1 - 60 gr/gal or 20 - 1080 ppm.
It is useful to make a note of your water
hardness so that you can provide the
service technician with this information
in the event of any service calls.

Filling the salt reservoir
Only special, coarse-grained
reactivation salt* should be used in
this lab washer.
*Available from Miele. 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 Technical Service.
The salt reservoir holds approximately
2.5 kg salt.
Inadvertently filling the salt
,
reservoir with detergent will damage
the water softener.
Before filling the reservoir, make
sure that you are using reactivation
salt.
Water softener
Place the funnel provided in place.
^
^ Carefully fill the reservoir with the
reactivation salt.
Some displaced water will run out - this
is normal.
^
Remove the bottom basket from the
machine.
^
Unscrew the salt reservoir cap.
Before filling the salt reservoir for the
first time fill the reservoir with
approximately 2.5 liters of water, so
that the salt can dissolve properly.
Once the lab washer has been
operated, there will always be
enough water in the reservoir.
15
Water softener
Wipe any residual salt off the screw
^
threads and seal of the reservoir.
^ Screw the cap on securely.
^ Immediately after this step, start the
"Rinse" program, to remove any
traces of salt from the inside of the
lab washer.
Note: There may be a delay of a few
minutes before the "Rinse" program
starts due to the reactivation of the
water softener.
Salt indicator
When the salt reservoir is empty, the
"Recharge Softener" indicator b lights
to remind you to fill the reservoir.
Reactivation takes place automatically
as needed during a program. The
"Recharging" indicator a lights while
this is occurring.
16
Use only special processing
,
chemicals for lab washers and
observe the manufacturer's
recommendations for use. In
particular, always observe the
manufacturer's instructions
regarding residual amounts that do
not pose any toxicological risk.
Adding rinse aid
Rinse aid is not used in laboratory
glassware cleaning applications.
Open the machine door.
^
Rinse Aid
If rinse aid is required, the rinse aid
dosage must be activated with
assistance from Miele Technical
Service.
Rinse aid (e.g., MieleClear) is filled in
the storage container, and the selected
dose is then dispensed automatically.
The rinse aid reservoir holds
approximately 180 ml.
,
Inadvertently filling the rinse aid
reservoir with detergent will damage
the lab washer. Be sure only to use
rinse aid in the rinse aid reservoir.
^ Unscrew the reservoir cap.
^
Pour enough rinse aid into the
reservoir so that the level indicator
(see arrow) is dark. Use a funnel if
necessary.
^
Replace and tighten the reservoir
cap.
^
Wipe up any spilled rinse aid, to
prevent over sudsing during the next
wash cycle.
17
Rinse Aid
Rinse aid indicator light
^ Rinse aid does not need to be refilled
until the "Rinse aid" indicator light
comes on in the display.
Setting the rinse aid dosage
The dosage selector has settings from
1 to 6 (1 - 6 ml). The factory setting is at
3 (3 ml).
If the glassware shows spots after
washing,
^ adjust to a higher setting.
If the glassware shows smearing or
cloudy streaks after washing,
18
^
adjust to a lower setting.
Neutralizing agent
Adding neutralizer
Neutralizer has an acidic pH, and
works by neutralizing any traces of
(alkaline) cleaner from the surface of
the glassware.
When a mild alkaline detergent is
used for washing, select a
neutralizer that contains phosphoric
acid.
The neutralizer is automatically
dispensed during the second rinse
after the main wash cycle. To function
properly, the neutralizer container must
be filled and cleared of air (primed).
For specific instructions see
"Programming functions".
Note: the program "Inorganica"
dispenses neutralizer after the
pre-wash.
Take out the (red) neutralizer
^
container and refill it or replace it with
a filled container.
^ Insert the siphon tube into the
container opening and screw it into
place. Make sure to observe the
color coding.
^ Then place the container on the floor
next to the machine.

,
formulated for this machine. Do not
use detergents formulated for
household dishwashers.
Liquid detergent
It is recommended that mildly alkaline
liquid detergents be dispensed via the
optional DOS module.
Note
As a separate option, this machine can
also be fitted with a dispenser pump for
automatic liquid detergent dispensing
(DOS-Module G 60). This is connected
externally. Contact Miele for details.
The optional DOS Module G 60 is
supplied with its own installation and
connection instructions.
See "Programming functions" for
information on priming the dispensing
system and setting the dosage.
Using powdered detergent
Avoid inhaling cleaning agents
,
in powder form. If processing
chemicals are ingested, they can
cause chemical burns in the mouth
and throat or suffocation.
When the following upper baskets
are used, powdered detergent can
be loaded inside the door, but only
for programs without a pre-wash
cycle. In all other cases, use liquid
detergent (DOS module):
– O 175
– O 176
– O 176/1
– O 183
– O 184
– O 187
– O 190/2.
Before starting the program, load the
powdered detergent into the
compartment (except for the programs
"Rinse" and "Drain").
Note also that the program
"Organica" can only be used with
liquid detergents.

Loading the machine
Depending on the type of labware you
wish to clean, the lab washer can be
used with an upper basket, lower
basket, or injector wagon, as well as an
assortment of inserts and special
baskets to suit your needs.
Baskets and inserts should be
properly selected to match the
application desired.
Before every program start, conduct
the following visual inspection:
– Is the labware properly loaded and
secured in the lab washer?
– Are the hollow vessels properly
loaded so that all cavities and
channels will be flushed clean?
– Are the spray arms clean, and can
they rotate freely?
– Is the filter combination free of
coarse debris (remove any coarse
material and clean the coarse, fine,
flat, and micro-fine filters as
needed)?
After every program completion,
conduct the following visual
inspection:
Inspect the labware for cleanliness.
–
Has any hollowware been dislodged
–
from its proper position on the
nozzles?
Any items that were dislodged
,
from the adapters during a program
cycle must be washed again.
Are the cavities and channels in any
–
hollow vessels cleaned through?
– Are the nozzles and connections
firmly attached to the
baskets/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.
–
Is the basket adapter properly
connected to the water supply for the
spray arms and nozzles?
–
Are the chemical dispensers filled?

Loading the machine
Loading the machine
Always load items in a way that all
–
surfaces are exposed. This ensures
that the items will be properly
cleaned.
Do not nest any items inside other
–
items. Keep each item separate.
Hollow vessels must be arranged for
–
complete inside exposure to the
cleaning water.
Prior to loading the machine or
–
connecting to the machine ensure
that vessels with long, narrow
cavities they can be completely
flushed.
Do not use this machine to wash
–
nickel-plated items or discolored
(oxidized) aluminum items.
Do not load plastics unless they are
–
heat-resistant.
Prepare items before loading
Empty all glassware before loading
^
into the machine. Comply with all
applicable infection-control
regulations.
Remove all agar residue from petri
^
dishes.
^ Remove any blood clots and blood
residue.
– Hollow vessels should be inverted
and placed in suitable baskets and
inserts so that water will have
unrestricted access and exit.
– Deep-based items should be
arranged at an angle, so that water
can run off easily.
–
Tall, narrow pieces should be placed
in the center of the basket for best
water coverage.
–
Secure light loads with netting and
place small items in a mesh
tray/basket so that they do not
obstruct the spray arms.
–
Baskets and inserts with an adapter
must be properly connected.
–
The spray arms must not be blocked
by items that are too tall or hang
through the baskets.
–
To avoid corrosion, only load
stainless steel instruments in good
condition.
^ Remove all stoppers, corks, labels,
sealing wax residue, etc.
,
Ensure that no acid or solvent
residues, especially hydrochloric
acid or chlorides, get inside the
machine.
Special preparations before
operating the machine
Items effected by heavy contamination
that resists removal, such as vacuum
grease, paper labels, etc., can affect
the cleaning and rinsing of the whole
load. Pre-treat these items before
loading.
Lab equipment that is contaminated by
microbiological material, pathogens,
propathogens, genetically altered
material, etc., may need to be sterilized
before being washed in the lab washer.
The user is responsible for this
decision.
