Function of the Dental Thermal Disinfector
High-level disinfection
The G 7881 Dental Thermal Disinfector
is suitable for automatic treatment of
dental instruments and accessories. It
cleans and in the disinfection program
simultaneously thermally disinfects, at
200°F/93°C, instruments and
accessories.
Areas of effectiveness are physical
removal or thermal inactivation of
vegetative bacteria including
mycobacteria, fungi, fungal spores, and
viruses. These categories include the
Mycobacterium tuberculosis and the
Enterococcus faecium.
Important: Only the programs labeled
"Disinfection" disinfect! Only use this
program when handling contaminated
items. All other programs are designed
to clean items without disinfecting
them.
All relevant safety procedures should
be obeyed. Relevant safety procedures
include, but are not limited to, the
Centers for Disease Control’s
Recommended Infection Control
Practices for Dentistry and the OSHA
Bloodborne Pathogens Standard.
The G 7881 Dental Thermal Disinfector
achieves high-level disinfection as
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.
8
According to the Centers for Disease
Control’s Recommended Infection
Control Practices for Dentistry,
instruments should be classified in one
of the following categories and be
treated accordingly:
All critical instruments must be
sterilized after treatment in the G 7881
Dental Thermal Disinfector. Critical
instruments are used to penetrate soft
tissue or bone, e.g. forceps, scalpels,
bone chisels or scales.
Semicritical instruments should be
sterilized after treatment in the G 7881
Dental Thermal Disinfector. If however,
sterilization is not feasible because the
instrument will be damaged by higher
heat exposure, the instruments may be
treated thermally in the G 7881 Dental
Thermal Disinfector. Semicritical
instruments do not penetrate soft
tissues or bone but contact oral tissues,
e.g. mirrors and amalgam placement
instruments.
Noncritical instruments may be
treated thermally in the G 7881 Dental
Thermal Disinfector. Noncritical
instruments or devices come into
contact only with intact skin, e.g.
external components of x-ray heads.
Function of the Dental Thermal Disinfector
Instruments suitable for processing
in the thermal disinfector
In general, only high quality stainless
steel instruments are suitable for
processing in the G 7881. All
instruments, accessories and other
items to be cleaned and disinfected in
the machine should have the following
properties:
– heat resistance to a temperature of
up to 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 instruments may discolor
during the cleaning process. Aluminum
has only a limited suitability for
processing in this system.
Carbon steel and chrome-plated
instruments may corrode during the
cleaning process. Processing these
types of instruments in the G 7881 is
not recommended.
Hand pieces, drill bits, grinders, root
canal instruments or other rotating
instruments are not suitable for the
thermal disinfector. Do not process
them in the thermal 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 instrument is suitable for
processing in the G 7881 Dental
Disinfector, please seek the advice of
the instrument manufacturer.
Water quality
Good water quality is essential for
processing instruments in the dental
washer disinfector. Otherwise,
instrument 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 instruments to rust when
processed in the machine. Other
effects that may be noticed are
tarnishing or "blueing" of instruments
due to dissolved minerals in the water.
If you notice any of the above
symptoms in your instruments, please
contact a Miele Applications
Specialist at:
(800) 991-9380
Do not clean fiberoptics or electrical
equipment and components in the
thermal disinfector.

Before using for the first time
Load the machine carefully
Before using 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 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.
12
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.

water results in calcium deposits on the
instruments and machine.
If your tap water hardness is above 4°d,
the water should be softened. This
takes place by properly programming
the unit's integrated water softener.
– The water softener must be filled with
salt for reactivation.
– The disinfector must be programmed
to correspond to the water hardness
in your area.
– The local water authority can advise
you of the water hardness in your
area or your sales representative can
assist you.
For fluctuating levels (e.g. 7 - 13 gpg)
set the water softener to the highest
setting (in this example to 13 gpg).
The built-in water softener has
settings from 1 - 60 gr/gal or
20 - 1080 ppm.

Effects of Processing Chemicals
General information
Effects
Action
Damage to elastomer (seals and hoses)
or plastic components of the machine
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.
– Find and correct the causes of the
damage.
See "Connected processing
chemicals", "Soiling" and "Reactions
between processing chemicals and
soils" for more information.
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 machine.
If foaming occurs, the cleaning process
is not standardized and not validated.
– 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..
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 machine. 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 cause of the
corrosion.

Connection to the water inlet
,Water in the machine is not
suitable for drinking.
^ For technical application reasons, the
machine is supplied as standard for
connection to cold water only.
The inlet hoses (water inlet and
steam condenser) must only be
connected to the cold water inlets.
See also "DI water connection" (hose
marked H2O pur).
^ The machine must be connected to
the water supply in accordance with
local and national regulations.
^ High iron content can leave a rust
film on stainless steel labware and
the machine itself.
When the chloride content in the
domestic water supply is above
100mg/l, the risk of corrosion
damage to stainless steel labware is
greatly increased.
^ Connections with a 3/4" GHT male
thread are to be provided on site.
They should be easily accessible so
that the water supply can be turned
off when the machine is not in use.
^ All inlet hoses are approx. 5 ft.
(1.5 m) long, ending with a 3/4" GHT
female thread. Under no
circumstances should the inlet filters
be removed.
^ Large surface area filters are
enclosed with the machine for
installing between the inlet and the
inlet hose.
(see "Machine care - Cleaning the
filters in the water inlet").
^ In certain regions (e.g., mountainous
areas) the water composition may
cause condensate to form, requiring
the use of softened water in the
steam condenser.
^ Acceptable water pressure
(flow rate): 10 - 147 psi
Recommended water pressure
(flow rate): 25 - 60 psi
^ If the water pressure is not in the
range listed above, the "Fill/Drain"
indicator may come on and the fault
code "F..E" will appear in the display.
If this occurs, contact the Miele
Technical Service Department for
advice.
,The inlet hose must not be
shortened or damaged in any way
(see illustration).

If required the machine can be
connected as standard to a DI water
supply of:
Acceptable water pressure
(flow rate): 10 - 147 psi
Recommended water pressure
(flow rate): 25 - 60 psi
^ The DI pressure-tested hose (marked
"H2O pur") with a 3/4" (19 mm) GHT
female hose thread must be
connected onsite to the DI inlet for
purified water.
If the machine has a DI water
connection which is not going to be
used, the electronics will need to be
reprogrammed by a Miele
technician. The inlet hose will remain
at the rear of the machine.
66
Plumbing
Drainage
^ The drainage system is fitted with a
non-return valve which prevents dirty
water from flowing back into the
machine via the drain hose.
^ The machine should preferably be
connected to a separate drainage
system onsite.
If separate drainage is not available
contact your Miele application
specialist for advice.
The onsite drain connection point
should be located between 1 ft.
(0.3 m) and 3 ft. (1 m) above the
lower edge of the machine.
If it is lower than 1 ft. (0.3 m), lay the
hose in a curve at a height of at least
1 ft. (0.3 m).
The drainage system must be able to
take a minimum drainage flow of
16 l/min.
^ The drain hose is approx. 5 ft. (1.5 m)
long, is flexible and has an internal
diameter of 7/8 in. (22 mm). It must
not be shortened. Hose clamps are
supplied for securing it in position.
