Miele G 7881 User Manual

							High -level disinfection
The washer-disinfector cleans items,
and in the disinfection program,
simultaneously thermally disinfects at
93°C/200°F.
Areas of effectiveness are physical
removal or thermal inactivation of
vegetative bacteria including
mycobacteria, fungi, fungal spores and
viruses. These catergories include the
Mycobacterium tuberculosis and the
Enterococcus faecium.
Important: Only the program labelled
"disinfection" disinfects! Only use this
program when handling contaminated
items. All other programs are designed
to clean items without disinfecting.
The washer-disinfector achieves
high-level disinfectionas defined by
the Spaulding categorization.
The Spaulding category high-level
disinfection is the same type of means
as in the sterilant category except that
the use pattern is different. The sterilant
is used as a high-level disinfectant by
e.g. reducing the exposure time within
its effective range of tuberculocidal,
virucidal and bactericidal action.Instruments suitable for processing
in the washer-disinfector
In general, only high quality stainless
steel items are suitable for processing
in the washer-disinfector. All items to be
cleaned and disinfected in the
washer-disinfector should have the
following properties:
–heat resistance to a temperature of
95°C/203°F
–corrosion resistance in the presence
of heat and alkalinity.
The heat retention capacity of stainless
steel allows for fast drying. Plastic has a
lower heat retention capacity, thus
requiring a longer drying time. In this
case, a slightly extended waiting period
of 5-15 minutes may be necessary after
the disinfection cycle.
Aluminum items may discolour during
the cleaning process. Aluminum has
only a limited suitability for processing
in the washer-disinfector.
Carbon steel and chrome-plated items
may corrode during the cleaning
process. Processing these types of
items in the washer-disinfector is NOT
recommended.
Hand pieces, drill bits, grinders, root
canal instruments or other rotating
items are not suitable for the
washer-disinfector. Do not process
them in the washer-disinfector.

							Do not clean fiberoptics or electrical
equipment and components in the
washer-disinfector.
Rhodium coated mirrors must be
arranged so that their surfaces do not
suffer any mechanical damage. Not all
specula with glass are suitable for
machine treatment.
If you have questions regarding
whether an item is suitable for
processing in the washer-disinfector,
please seek the advice of the item
manufacturer.
Water Quality
Good water quality is essential for
processing items in the
washer-disinfector, otherwise, item
corrosion may result.
Poor water quality consists of, but is not
limited to, high concentrations of
chlorides (over 50 ppm). High chloride
levels will cause even high quality
stainless steel items to rust when
processed in the washer-disinfector.
Other effects that may be noticed are
tarnishing or "blueing" of items due to
dissolved minerals in the water.

							Disposal of packing materials
The packing materials help protect the
appliance during transport. They have
been selected with an eye to
environmental compatibility and
efficient disposal and should be
recycled.
Returning packaging to the materials
cycle saves raw material and reduces
waste.
Disposing of your old
appliance
Old electric and electronic equipment
often contains valuable materials but
they may also contain harmful
substances that were necessary for
safe use. Improperly disposing of these
items in your household waste can
harm human health and the
environment. This is why it is important
to NEVER dispose of your old
appliance with the regular household
garbage.
Instead, please contact your local
community waste collection point to
return and recycle electric and
electronic appliances.
If the appliance is being stored for
disposal, please make sure it has been
child-proofed.

							Before using the machine for the first
time please pay special attention to
the following points:
Detailed information on these points
can be found in the relevant section
of the Operating Instructions.
Set the water softener
The water softener must be set to the
water hardness level of your area.
Contact your local water authority to
find your water hardness level in parts
per million (ppm) or grains per gallon
(gr/gal).
The salt reservoir must be filled first
with water and then with reactivation
salt.
Filling the salt reservoir with cleaning
agent by mistake will cause serious
damage to the water softener. Please
check every time before refilling that
the package contains reactivation salt.
Add rinsing agent
Inadvertently filling the rinsing agent
reservoir with cleaning agent
(including liquid cleaning agents
and dishwashing soap) will cause
serious damage to the reservoir.
Only use detergents suitable for use
in disinfecting washers.
Do not use detergents formulated for
use in domestic dishwashers.Load the machine carefully.
Arrange the load so that water will
come into contact with all surfaces.
Concealed surfaces will not be
cleaned.
The spray arms must not be blocked by
any items.
Adding detergent
Follow the dosage recommendations of
the cleaning agent manufacturer.
The filter combination at the base of
the wash cabinet and the spray arms
must be clean.
Regular checking and cleaning is
essential.

							In order to provide good cleaning
results, the machine requires a supply
of soft water (water that is low in
calcium and magnesium). If hard tap
water is used, it can leave a white
mineral deposit build-up on the items
and the machine itself, therefore, tap
water with a hardness of 4 °d
(0.7 mmol/l) or more must be softened.
The built-in water softener is designed
for this purpose.
–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 will provide
information about the hardness of the
tap water in your area.
If the water hardness is known to
fluctuate (e. g., 8 - 17 °d), always
program for the highest value (in this
instance 17 °d).
The built-in water softener can be
programmed at settings from 1 °d to
60 °d (1-60 gr/gal or 20-1080 ppm).
It is useful to make a note of the water
hardness so that you can provide the
service technician with this information
in the event of any service calls.
Please note the water hardness in the
space provided here:

							How to fill the salt reservoir
Only use special, coarse-grained, Miele
reactivation salt with a grain size of
1 - 4 mm. NEVER use other types of
salt, such as table salt, cattle salt or
de-icing salt. These salts can contain
components that are insoluble in water
and could damage the water softener.
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, always
make sure that you are using
reactivation salt.
^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
washer-disinfector has been
operated, there will always be
enough water in the reservoir.^Place the provided funnel accessory
over the salt reservoir.
^Carefully fill the reservoir with
reactivation salt.
Some displaced water will run out - this
is normal.
^Wipe any residual salt off the screw
threads on the reservoir.
^Screw the cap back on completely.
^
Immediately after this step, start the
"Rinse" program, to remove any
traces of salt from the inside of the
machine.
Note: There may be a delay of a few
minutes before the "Rinse" program
starts - this is normal. It simply
means the water softener is being
reactivated as needed.
