Warning and safety instructions

Warning and Safety instructions

For pre-treatment and / or cleaning

only use low-foaming detergents
and disinfecting agents which have
been approved by Miele. Foam can
have an adverse effect on the disinfec­tion and cleaning process.

Where a chemical additive is re-

commended on technical applica­tion grounds (for example with a clean­ing agent), this does not imply that the
manufacturer of the machine takes re­sponsibility for the effect of the chemi­cal on the material of the items being
cleaned. Please be aware that change­s in formulation, storage conditions etc,
which may not be publicised by the
chemical producer, can have a nega­tive effect on the cleaning result.

When using cleaning agents and

specialised products it is essential
that the manufacturer’s instructions are
followed. Only use the product for the
application described by the manufac­turer, to avoid any material damage or
the occurrence of strong chemical reac­tions such as oxyhydrogen.

The machine is designed only for

operation with water and additive
cleaning agents. Organic solvents
must not be used in the machine, as
there is the danger under certain cir­cumstances of explosion. Although this
is not the case with all organic sol­vents, other problems could arise with
their use, for example damage to rub­ber and synthetic materials.

In critical applications where very

stringent requirements have to be
met, it is strongly recommended that all
the relevant factors for the process,
such as cleaning agent, quality of
water are discussed with the Miele Ap­plication Technology specialists.

If the cleaning result is subject to these
particularly stringent requirements (e.g.
chemical analysis, specialised pro­cesses), a regular quality control test
should be carried out by the user to en­sure that required standards of cleanli­ness are being achieved.

Please follow the advice on installa-

tion in these instructions and the
separate Installation Instructions.

Empty any containers or utensils

before arranging them in the ma­chine.

Do not allow any remains of acids

or solvents, 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).

Ensure that solutions or steam con-

taining acid salts do not come into
contact with the steel outer casing of
the machine, to avoid any corrosion
damage.

Use special inserts in accordance

with the instructions provided.

Accessories

The only accessories to be used

with the special commercial ma­chine must be those supplied or ap­proved by MIELE for the specific appli­cation. Consult your dealer or the Miele
Professional department for advice.

Disposal of an old machine

When disposing of an old machine

first make it unusable. Disconnect,
cut off the cable and any plug from the
cable. For environmental and safety
reasons ensure the machine is com­pletely drained of any residue water
and cleaning agent. (Observe safety
regulations and wear safety goggles
and gloves). Make the door lock inoper­ative, so that children cannot acciden­tally shut themselves in. The simplest
way to do this is to remove the locking
pin (2 philips screws above the door).
Make appropriate arrangements for the
safe disposal of the machine. For tank
system machines ensure that any water
is emptied out of the tank.

The manufacturer cannot be held re­sponsible for any damage caused
through non-observance of these
Warning and Safety instructions.

In countries where there are areas

which may be subject to infesta­tion by cockroaches or other vermin,
pay particular attention to keeping the
machine and its surroundings in a
clean condition at all times. Any dam­age which may be caused by cock­roaches or other vermin will not be
covered by the machine guarantee.

Description of the machine

The G 7783 is a front-loading automatic
machine for the efficient washing - neu­tralising - rinsing - final rinsing of labora­tory glassware. It can be operated on
normal water supply. There are “AD”
(aqua destillata) programmes with final
rinses using purified water (distilled,
R.O., or de-ionised).

Description of the machine

The effective areas are defined as fol­lows:

A = Suitable for destruction of vegeta­tive bacteria, including myco-bacteria
and fungus and fungal spores.

B = Suitable for inactivation of viruses
(including HBV and HIV).

On completion of the automatic pro­gramme sequence, laboratory glass­ware is cleaned to the standard re­quired for analysis.

The electronic control unit offers a
choice of temperatures for the cleaning
and final rinsing phases. A combination
often preferred is cleaning - T
and final rinse T

Setting the water softener

Setting the water softener

To avoid the build-up of calcium de­posits on glassware and in the ma­chine the water needs to be softened,
where the supply hardness exceeds
107 ppm, (6°d).

To ensure a steady supply of soft water
the water softener unit must always be:

1. correctly set, and

2. regenerated with salt as soon as

the k indicator light comes on.

The water softener must be set to corre­spond with the water hardness
time the machine is used.

Your local water authority will advise
you on the water hardness in your area.

Applications and loading

This laboratory glasswasher normally
requires a top and a bottom basket.

Depending on the type and shape of
the glassware, inserts can be supplied.
The diversity of the inserts is so great
that it is not possible to illustrate them
all or give detailed instructions on their
use here. As an example there are in­serts for direct injection spraying of vol­umetric flasks, butyrometers, pipettes
etc.
General glassware used in labora­tories, e.g. beakers, conical flasks, test
tubes, etc., can be arranged in full­size, half or quarter inserts in top or bot­tom baskets. Your Miele laboratory
dealer will advise on specific require­ments.

The following instructions relate only to
basic preparation and loading of glass­ware.

Arranging the load

Removing excess soils

Empty all glassware before loading
into the machine, (observe any ap­plicable hygiene regulations).

Ensure that no acid or solvent
residues, especially hydrochloric
acid or chlorides get into the wash
cabinet.

Applications and loading

Please note:

Load the glassware so that water will
come into contact with all surfaces.
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. A cover net can be
used to reduce the risk of movement
during the wash process.
Petri dishes and similar should be
placed in the correct insert with the
soiled side facing the centre.
Pipettes should be placed with the
mouthpiece facing upwards.
Deep based items should be placed
at enough of an angle for water to
run off them freely.
Tall, narrow, hollow pieces should be
placed in the centre of the basket to
ensure good coverage of water.
Do not cover the funnel in the middle
of the top basket. Mobile injector
units or baskets with an adapter
must engage correctly, (see next
page).
The spray arms must not be blocked
by items which are too tall for the
basket or which hang down in their
path. If necessary, manually rotate
the arms to test this.

Remove all agar residues from petri
dishes.
Remove blood clots and residues.
Remove all stoppers, corks, labels,
sealing wax residues, etc.

13

Applications and loading

Loading the machine

Important:

Make sure that the spring adapter for
water connection engages correctly

Rinsing agent

Rinsing agent

A liquid storage container incorporated
in the door has a capacity of approxi­mately 200 ml. The required amount of
appropriate liquid rinsing agent (e.g.
Mielclear where available) is dispensed
automatically from this container.

Adding rinsing agent

Pour rinsing agent into the storage
container until the level indicator is
dark (see arrow in illustration). Use
funnel if necessary.

Firmly tighten the screw cap. Clean
up any spillage.

Refilling with rinsing agent

The level indicator shows how much
rinsing agent is left in the container.
When there is no dark colouring visible
in the level indicator, the container
needs to be refilled.

Setting the dosage

Undo the screw cap.

The dosage adjuster in the opening
has settings from 1-6 (1-6 ml). It is set
to “3" (3 ml) at the factory.

Use a higher setting if spots are left
after drying.

If clouding or smearing appears, use
a lower setting.

17

Adding neutralising agent

Adding neutralising agent

Adding neutralising agent

To reduce the pH to neutral after al­kaline cleaning, special neutralising
acids can be used in programme
stage 4.

Important: “Special functions” must first
be used to set the programme to dis­pense neutralising agent in stage 4, in­stead of rinsing agent.

Place the container with neutralising
agent on the floor next to the ma­chine.

When the w indicator light on the con­trol panel lights up:

Fill the container with neutralising
agent, or change containers, and
then:

Re-fill the container in good time, it
should never be allowed to empty
completely.

Place the siphon tube firmly in the
opening of the free-standing con­tainer (pay attention to colour cod­ing).

chlorine-free cleaner should be used.

Under certain circumstances, i.e. spe­cial soiling, different combinations of
detergents and other additives may be
necessary. Consult your Miele labora­tory dealer.

Take care when handling liquids
such as detergents, disinfecting and
neutralising agents. These may con­tain acids, alkalis or disinfectants.
Follow the relevant safety procedures
and the instructions on the packa­ging carefully.
Wear protective gloves and
goggles if necessary.

Programme selection

Choose your programme according to
the type of glassware and the degree
of soiling.

The different programmes and their ap­plications are described overleaf in the
Programme chart.

When selecting a detergent please
bear in mind the ecological effects, in
particular the following considerations:

How much alkalinity is needed to do
the required cleaning?

Is bleach required for disinfection or
stain removal?

Are tensides at all necessary for dis­persal or emulsification?

place, and make them available to
future users.

Correct usage

This machine is designed for com-

mercial use and for specialised ap­plications only, as described in these
Operating Instructions. Using it for pur­poses other than those for which it was
designed would be unauthorised and
could cause harm.
The manufacturer cannot be held re­sponsible for damage caused by im­proper use.

Do not install the machine in an
area where a danger of explosion

may be present.

The electrical safety of this ma-

chine can only be guaranteed if
connected to a correctly installed ear­thing system on site. It is most import­ant that this basic safety requirement is
met and complies with local and na­tional regulations. It should be checked
by an expert if necessary.
The manufacturer cannot be held re­sponsible for damage caused by mis­sing or defective earthing, such as
electric shock.

A damaged machine is dan-

gerous. Switch off at the mains im­mediately and call an authorised Miele

Warning and safety instructions

Warning and Safety instructions

Take care when handling liquids

such as detergents, wetting
agents, or neutralising agents. These
may contain irritant or corrosive ingre­dients, acids or alkalis. On no account
use any organic solvent, as there may
be the danger of an explosion occur­ring.
Follow the instructions and relevant
safety procedures carefully. Wear pro­tective gloves and goggles.

Avoid inhalation of powder

cleaners. They can cause burning
in the mouth and throat if swallowed, or
inhibit breathing.

The water in the machine must not

be used as drinking water.

Do not sit or lean on the open

door, or rest objects on it. This
could cause the machine to tip and be
damaged.

Be careful when sorting items with

sharp pointed ends and position­ing them in the machine that you do not
hurt yourself or create danger for other
operators.

When using this machine in the

temperature ranges from 70 to
95°C be especially careful not to scald
or burn yourself. Baskets and inserts
must first cool down. Any water which
may remain in containers will be very
hot and must be emptied into the wash

Warning and safety instructions

Warning and Safety instructions

For pre-treatment and / or cleaning

only use low-foaming detergents
and disinfecting agents which have
been approved by Miele. Foam can
have an adverse effect on the disinfec­tion and cleaning process.

Where a chemical additive is rec-

ommended on technical applica­tion grounds (for example with a clean­ing agent), this does not imply that the
manufacturer of the machine takes re­sponsibility for the effect of the chemi­cal on the material of the items being
cleaned. Please be aware that change­s in formulation, storage conditions etc,
which may not be publicised by the
chemical producer, can have a nega­tive effect on the cleaning result.

When using cleaning agents and

specialised products it is essential
that the manufacturer’s instructions are
followed. Only use the product for the
application described by the manufac­turer, to avoid any material damage or
the occurrence of strong chemical reac­tions such as oxyhydrogen.

The machine is designed only for

operation with water and additive
cleaning agents. Organic solvents
must not be used in the machine, as
there is the danger under certain cir­cumstances of explosion. Although this
is not the case with all organic sol­vents, other problems could arise with
their use, for example damage to rub­ber and synthetic materials.

In critical applications where very

stringent requirements have to be
met, it is strongly recommended that all
the relevant factors for the process,
such as cleaning agent, quality of
water are discussed with the Miele Ap­plication Technology specialists.

If the cleaning result is subject to

these particularly stringent require­ments (e.g. chemical analysis, spe­cialised processes), a regular quality
control test should be carried out by
the user to ensure that required stand­ards of cleanliness are being achieved.

Please follow the advice on installa-

tion in these instructions and the
separate Installation Instructions.

Empty any containers or utensils

before arranging them in the ma­chine.

Do not allow any remains of acids

or solvents, 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).

Ensure that solutions or steam con-

taining acid salts do not come into
contact with the steel outer casing of
the machine, to avoid any corrosion
damage.

Use special inserts in accordance

with the instructions provided.

Accessories

The only accessories to be used

with the special commercial ma­chine must be those supplied or ap­proved by MIELE for the specific appli­cation. Consult your dealer or the Miele
Professional department for advice.

Disposal of an old machine

When disposing of an old machine

first make it unusable. Disconnect,
cut off the cable and any plug from the
cable. For environmental and safety
reasons ensure the machine is com­pletely drained of any residue water
and cleaning agent. (Observe safety
regulations and wear safety goggles
and gloves). Make the door lock inoper­ative, so that children cannot acciden­tally shut themselves in. The simplest
way to do this is to remove the locking
pin (2 philips screws above the door).
Make appropriate arrangements for the
safe disposal of the machine. For tank
system machines ensure that any water
is emptied out of the tank.

The manufacturer cannot be held re­sponsible for any damage caused
through non-observance of these
Warning and Safety instructions.

In countries where there are areas

which may be subject to infesta­tion by cockroaches or other vermin,
pay particular attention to keeping the
machine and its surroundings in a
clean condition at all times. Any dam­age which may be caused by cock­roaches or other vermin will not be
covered by the machine guarantee.

Reactivating the water softener

Reactivating the water softener

When the k indicator light on the left
hand side of the control panel comes
on during a programme the built-in
water softener is depleted and cannot
supply any more softened water. It
must therefore be reactivated with
washer salt as soon as the programme
has finished.

If this cannot be done immediately, and
further batches have been washed,
then the reactivation process must be
carried out twice in succession.

Only use special coarse grained dish­washer salt (granule size approx. 1-4
mm), for reactivation, as other salts
may contain insoluble impurities or ad­ditives which can impair the functioning
of the softener.

The salt container holds approx. 2 kg
salt.

Important

If the only reactivation salt available is
fine grain, please consult your Miele
service representative.

Reactivation salt with granules larger
than 4 mm cannot be used.

28

Unscrew the filter insert from the salt
container and remove.

Fill the salt container with granular
dishwasher salt and screw the filter
insert back in place.

Reactivating the water softener

Position the salt container as
follows:

Remove the bottom basket from the
machine.

Unscrew the plastic cap in the base
of the wash cabinet.

Reactivating the water softener

Switch on the machine

Open the stopcocks if previously closed.
Close the door.
Press I-0.
Press the k touch pad.

Press the "Start" h touch pad.
The reactivation programme proceeds
automatically and finishes when the in­dicator light k at the left hand side of
the control panel and the "Start" indica­tor light h have gone out.

Then:

Switch off the machine.

Unscrew the salt container carefully,

so that any water pressure that has

built up can be released. Do not use

force. If you cannot uncrew the salt

container by hand, contact the Miele

Service department.

Screw the plastic lid back on the socket.

Reposition bottom basket.

Rinse the salt container and filter in-

sert thoroughly.

Turn off the stopcocks if the machine

is not to be used again for some time.

Place the salt container on the reacti­vation socket and screw firmly into
place.

Important

The water pressure (flow pressure at the
take off point) must be at least 2.5 bar.
If it less than this see "Programming spe­cial functions".

If the flow pressure is below 2.5 bar, or
if it fluctuates, the water softener can­not be reactivated in the normal way.
After reactivation, salt remains may still
be found in the salt container.

To use up the salt remains and to wash
out the water softener, the "reactivate
softener" programme must be switched
on again.

corrected without contacting the Miele
Service Department.

Any work on the electrical components
of the machine should only be carried
out by a suitably qualified and compe­tent person.

Faults / Possible Causes

The water in the wash cabinet is not
heated; the programme sequence
lasts too long.

This machine has a resettable heater
limiter which will switch off the heaters
in the case of over-heating. This could
be caused for example, if large articles
obscure the heating elements or if the
filters in the wash cabinet are blocked.

Remove cause of fault.

the local and national regulations,
(NWC in GB).

The machine is constructed to com­ply with DVGW regulations, in such a
way that an external non-return valve
is not required.

The water pressure (flow rate) must
be between 2.5 and 10 bar. If the
water pressure is not within this
range, the Customer Service Depart­ment will advise you of the measures
to take (see also “Programming spe­cial functions”).

The machine is supplied as stan­dard for connection to cold (blue

connection is available. In this case
both hoses must be connected to
the cold water supply.
In special cases, (see Programme E
in the chart), connection of both
hoses to hot water is recommended.
In order to prolong its life, the hose

Stopcocks with 3/4 “ BPS male
thread to be provided on site. They
should be easily accessible because
the water supply must be turned off
when the machine is not in use.

The DN 10 inlet pressure hoses are
approximately 1.7m long and termi­nate in a 3/4" female thread. On no
account must the inlet filters be
removed.

For additional protection of the sole­noid valve against impurities in the
water supply, large surface area fil­ters are enclosed in the kit supplied
with the machine (see illustration in
“Cleaning and care, water inlet”).

The filter for AD purified water is made
from chrome-nickel steel and has a
matt upper surface.

AD connection to purified water, press­urised, (1.5 - 10 bar)

The machine is delivered from the fac­tory ready for connection to a press­urised system, 1.5 - 10 bar.

The AD pressure tested hose,
marked H
must be connected to the on-site AD
stopcock for purified water.

Connection to purified water non­pressurised (0 - 1.5 bar)

For connection to a supply of 0 - 0.3
bar, or 0.3 - 1.5 bar the machine must
be converted, if not supplied converted
ex-works. An "ADP" booster pump can
only be fitted. This is only possible
when the machine has no DHK steam
condensor. As this work requires
specialised knowledge, it should only
be carried out by a Miele approved
engineer.

The outlet of the purified water con­tainer (non-pressurised) must be at
least at the height of the upper edge of
the machine. (see "Installation instruc­tions").

Connect the non-pressurised AD
water hose to the purified water con­tainer

If the AD connection to purified
water is not being used (or if it
should not be used) then the ma­chine must be converted by a Miele
trained or approved engineer.

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
system on site. If no separate drain­age system is available, seek profes­sional advice.

The machine is supplied with flexible
drainage hoses with an internal
diameter of 22 mm, and approx. 1.5
m long.
The drain hose must not be short­ened.
Hose clips for connection are sup­plied.

Longer drain hoses (up to 4 m) are
available if required. Contact your
Miele laboratory dealer or Spare
Parts Department.

The drainage system must not ex­ceed 4 metres and the drain pump
has a maximum delivery head of 1
metre.

Disposal of the packing ma­terial

The transport and protective packing
has been selected from materials
which are environmentally friendly for
disposal and can normally be recycled.

Rather than just throwing these ma­terials away, please ensure they are
offered for recycling.

Disposal of your old machine

Old machines contain materials which
can be reclaimed or recycled. Please
contact your dealer, local waste collec­tion centre or scrap merchant about
potential recycling schemes. Ensure
that the machine presents no danger to
children while being stored for disposal.

When disposing of an old machine
first make it unusable. Disconnect,
cut off the cable and any plug from
the cable. For safety reasons en­sure the machine is completely
drained of any residue water and
cleaning agent. (Observe safety
regulations and wear safety
goggles and gloves). Make the
door lock inoperative so that child­ren cannot shut themselves in. The
simplest way to do this is to remove
the locking pin (2 philips screws
above the door). Make appropriate
arrangements for the safe disposal
of the machine.
Where machines with a tank system
are being disposed of, all water
must first be emptied from the tank.
