Warning and Safety instructionsTake care when handling liquidssuch as detergents, wetting

agents, or neutralising agents. Thesemay contain irritant or corrosive ingre-dients, acids or alkalis. On no accountuse any organic solvent, as there maybe the danger of an explosion occur-ring.Follow the instructions and relevantsafety procedures carefully. Wear pro-tective gloves and goggles.

Avoid inhalation of powdercleaners. They can cause burning

in the mouth and throat if swallowed, orinhibit breathing.

The water in the machine must notbe 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 dam-aged.

Be careful when sorting items withsharp pointed ends and position-

ing them in the machine that you do nothurt yourself or create danger for otheroperators.

When using this machine in thetemperature ranges from 70 to

95°C be especially careful not to scaldor burn yourself. Baskets and insertsmust first cool down. Any water whichmay remain in containers will be veryhot and must be emptied into the washcabinet.After drying with the TA drying unit thenopen the door to allow the items and in-serts to cool down.

Do not touch the heating elementsduring or directly after the end of a

programme, you could burn yourself.

Never use an ordinary or a highpressure hose on or in the vicinity

of the machine.

Before any maintenance or repairwork is undertaken, the machine

must be disconnected from the mainssupply, by switching off at the mainsisolator, or withdrawing the mains fuse.

The following points should be ob-served to avoid damage to the ma-chine and the loads being cleaned.

The standard of disinfection in theDisinfection programmes must be

confirmed by the user as a routine mat-ter. The process should be regularlychecked using chemical indicators,and bacteriologically at intervals usingbio-indicators, with full documentation.Proceed according to local health auth-ority regulations.

Disinfection programmes must notbe interrupted, as this can have a

limiting effect on the disinfection result.However, should an interruption benecessary. the complete programmemust be repeated.

Only use cleaning agents formu-lated for special processes and ap-

proved by Miele for use with this ma-chine. Use of unsuitable cleaningagents could adversely affect the loador the machine.


6

Warning and Safety instructionsFor pre-treatment and / or cleaningonly use low-foaming detergents

and disinfecting agents which havebeen approved by Miele. Foam canhave an adverse effect on the disinfec-tion and cleaning process.

Where a chemical additive is re-commended on technical applica-

tion grounds (for example with a clean-ing agent), this does not imply that themanufacturer of the machine takes re-sponsibility for the effect of the chemi-cal on the material of the items beingcleaned. Please be aware that changesin formulation, storage conditions etc,which may not be publicised by thechemical producer, can have a nega-tive effect on the cleaning result.

When using cleaning agents andspecialised products it is essential

that the manufacturer’s instructions arefollowed. Only use the product for theapplication described by the manufac-turer, to avoid any material damage orthe occurrence of strong chemical reac-tions such as oxyhydrogen.

The machine is designed only foroperation with water and additive

cleaning agents. Organic solventsmust not be used in the machine, asthere is the danger under certain cir-cumstances of explosion. Although thisis not the case with all organic sol-vents, other problems could arise withtheir use, for example damage to rub-ber and synthetic materials.

In critical applications where verystringent requirements have to be

met, it is strongly recommended that allthe relevant factors for the process,such as cleaning agent, quality ofwater are discussed with the Miele Ap-plication Technology specialists.

If the cleaning result is subject to theseparticularly stringent requirements (e.g.chemical analysis, specialised pro-cesses), a regular quality control testshould be carried out by the user to en-sure that required standards of cleanli-ness are being achieved.

Please follow the advice on installa-tion in these instructions and the

separate Installation Instructions.

Empty any containers or utensilsbefore arranging them in the ma-

chine.

Do not allow any remains of acidsor solvents, or chloride solutions to

get into the wash cabinet. Similarlyavoid any materials with a corrosive ef-fect.The presence in compounds of any sol-vents should be minimal, (especiallythose in hazard class A1).

Ensure that solutions or steam con-taining acid salts do not come into

contact with the steel outer casing ofthe machine, to avoid any corrosiondamage.

Description of the machineThe G 7783 CD is a front-loading auto-matic machine for the efficient washing- neutralising - rinsing - final rinsing oflaboratory glassware. It can be oper-ated on normal water supply. There are"AD" (aqua destillata) programmes withfinal rinses using purified water (dis-tilled, R.O., or de-ionised).

On completion of the automatic pro-gramme sequence, laboratory glass-ware is cleaned to the standard re-quired for analysis.

The electronic control unit offers achoice of temperatures for the cleaningand final rinsing phases. A combinationoften preferred is cleaning - T1 85° Cand final rinse T2 70 °C.

With the SPECIAL "B" programme themachine can thermally disinfect at90°C with relevant holding times.

"Instrument disinfection in automaticmachines" is to be found under subsec-tion 3.2.4. of paragraph 10c ofBSeuchG, according to the GermanFederal Health Authority, Berlin (BGA).The disinfection parameters of between90°C and 93°C held for 10 minutesapply to the effective areas A + B. Re-duction factor 7 (by reduction factor~107).

The effective areas are defined as fol-lows:

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

B = Suitable for inactivation of virusesIncluding HBV and HIV).

The SPECIAL "B" programme operatesat 90°C with 10 minutes holding time.

This machine is fitted with a TA dryingunit and water softener as standard.

Applications and loadingThis laboratory glasswasher normallyrequires a top and a bottom basket.

Depending on the type and shape ofthe glassware, inserts can be suppliedand there is a range of other basketsfor special applications. The diversity ofthe inserts is so great that it is notpossible to illustrate them all or give de-tailed instructions on their use here. Asan example there are inserts for directinjection spraying of volumetric flasks,butyrometers, pipettes etc.

General glassware used in labora-tories, e.g. beakers, conical flasks, testtubes, etc., can be arranged in full-size, half or quarter inserts in top or bot-tom baskets. Your Miele laboratorydealer will advise on specific require-ments.

The following instructions relate only tobasic preparation and loading of glass-ware.

Loading the machine

Removing excess soils

Empty all glassware before loadinginto the machine. Take any hygienemeasures necessary against infec-tion.

Ensure that no acid or solventresidues, especially hydrochloricacid or chlorides get into the washcabinet.

Remove all agar residues from petridishes.

Remove blood clots and residuesfrom test tubes, etc.

Remove all stoppers, corks, labels,sealing wax residues, etc.

Notes

Load the glassware so that water willcome into contact with all surfaces.This ensures that they will beproperly cleaned.

Do not place items to be cleaned in-side other pieces where they may beconcealed.

Hollow vessels such as beakers,measuring cylinders, flasks, etc.should be inverted and placed in thecorrect inserts. A cover net can beused to reduce the risk of movementduring the wash process.

Petri dishes and similar should beplaced in the correct insert with thesoiled side facing the centre.

Pipettes should be placed with themouthpiece facing upwards.

Deep based items should be placedat enough of an angle for water torun off them freely.

Tall, narrow, hollow pieces should beplaced in the centre of the basket toensure good coverage of water.

Do not cover the funnel in the middleof the top basket. Mobile injectorunits or baskets with an adaptermust engage correctly, (see below).

Applications and loading

Adding neutralising agent and (liquid) detergentAdding neutralising agentTo reduce the pH to neutral after alkalinecleaning, special neutralising acids canbe used in programme stage 4.

Important "Special functions" must firstbe used to set the programme to dis-pense neutralising agent in stage 4, in-stead of rinsing agent.

When the w indicator light on the con-trol panel lights up:

Fill the container DOS 10 (red mark-ings) with neutralising agent, orchange containers, and then:

Place the siphon tube firmly in theopening of the free-standing con-tainer (pay attention to colour cod-ing).

Re-fill the container in good time, itshould never be allowed to empty com-pletely.

Adding detergentsDetergent can be added in either liquidor powder form (for powder detergent,see relevant section, p. 18)

When the indicator light "DOS" on thecontrol panel lights up:

Fill the container DOS 60 (blue mark-ings) with liquid detergent, orchange containers, and then:

Place the siphon tube firmly in theopening of the free-standing con-tainer (pay attention to colour cod-ing).

Re-fill the container in good time, itshould never be allowed to empty com-pletely.

Note: If adding an extra dose of deter-gent in the pre-wash of programmes Eand F (see "Programme chart"), onlypowder detergent can be used.

Venting the liquid dispensing system / MaintenanceVenting the liquid dispensingsystemBefore using the machine for the firsttime, or if the container had not beenfilled in time and allowed to empty, thedispensing system for liquid agents(apart from rinsing agent) must bevented.

Proceed as follows:

Press the I-0 (ON-Off) button.

Switch "A":Dispensing system for neutralisingagent.

Switch "B":Dispensing system for detergent (ifusing liquid detergent).

Use a pointed object to press inswitch "A" and/or "B" at the left handside end of the control panel forthree and a half minutes.

Each time the system is vented any liq-uid which runs into the wash cabinetmust be washed out as follows:

Select programme "A" (Cold).

After this has run the dispensing sys-tem is filled and ready for use.

Checking the dispensingsystemTo maintain the performance of the dis-pensing system, it should be servicedat regular intervals.

This work should only be carried out bysuitably qualified people or by a MIELEService Engineer.

Every 12-18 months

– Replace the dispensing hoses ineither the dispensing systems or theDOS modules.

Adding detergent Programme selection

Programme "B", and when using O-175 or a pipette plate

Add powder detergent directly to theinside of the door or dispense liquiddetergent via DOS 60.

An additional dose of powder detergentcan be added to the inside of the doorwhere required in applications E and F(see Programme chart).

When selecting a cleaning agentplease bear in mind the ecological ef-fects, in particular the following con-siderations:

How much alkalinity is needed to dothe required cleaning?

Is bleach required for disinfection orstain removal?

Are tensides at all necessary for dis-persal or emulsification?

The thermal disinfection programmerequires the use of a suitable mildlyalkaline or active chlorine-freecleaner.

Under certain circumstances, i.e. spe-cial soiling, different combinations ofdetergents and other additives may benecessary. Consult your Miele labora-tory dealer.

Take care when handling liquidssuch as detergents, disinfectingand neutralising agents. These maycontain acids, alkalis or disinfec-tants. Follow the relevant safetyprocedures and the instructions onthe packaging carefully. Wear protective gloves andgoggles if necessary.

Programme selectionChoose your programme according tothe type of glassware and the degreeof soiling.

The different programmes and their ap-plications are described overleaf in the"Programme chart" .

Warning and Safety instructionsTake care when handling liquidssuch as detergents, wetting

agents, or neutralising agents. Thesemay contain irritant or corrosive ingre-dients, acids or alkalis. On no accountuse any organic solvent, as there maybe the danger of an explosion occur-ring.Follow the instructions and relevantsafety procedures carefully. Wear pro-tective gloves and goggles.

Avoid inhalation of powdercleaners. They can cause burning

in the mouth and throat if swallowed, orinhibit breathing.

The water in the machine must notbe 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 dam-aged.

Be careful when sorting items withsharp pointed ends and position-

ing them in the machine that you do nothurt yourself or create danger for otheroperators.

When using this machine in thetemperature ranges from 70 to

95°C be especially careful not to scaldor burn yourself. Baskets and insertsmust first cool down. Any water whichmay remain in containers will be veryhot and must be emptied into the washcabinet.After drying with the TA drying unit thenopen the door to allow the items and in-serts to cool down.

Do not touch the heating elementsduring or directly after the end of a

programme, you could burn yourself.

Never use an ordinary or a highpressure hose on or in the vicinity

of the machine.

Before any maintenance or repairwork is undertaken, the machine

must be disconnected from the mainssupply, by switching off at the mainsisolator, or withdrawing the mains fuse.

The following points should be ob-served to avoid damage to the ma-chine and the loads being cleaned.

The standard of disinfection in theDisinfection programmes must be

confirmed by the user as a routine mat-ter. The process should be regularlychecked using chemical indicators,and bacteriologically at intervals usingbio-indicators, with full documentation.Proceed according to local health auth-ority regulations.

Disinfection programmes must notbe interrupted, as this can have a

limiting effect on the disinfection result.However, should an interruption benecessary. the complete programmemust be repeated.

Only use cleaning agents formu-lated for special processes and ap-

proved by Miele for use with this ma-chine. Use of unsuitable cleaningagents could adversely affect the loador the machine.

Warning and Safety instructionsFor pre-treatment and / or cleaningonly use low-foaming detergents

and disinfecting agents which havebeen approved by Miele. Foam canhave an adverse effect on the disinfec-tion and cleaning process.

Where a chemical additive is rec-ommended on technical applica-

tion grounds (for example with a clean-ing agent), this does not imply that themanufacturer of the machine takes re-sponsibility for the effect of the chemi-cal on the material of the items beingcleaned. Please be aware that changesin formulation, storage conditions etc,which may not be publicised by thechemical producer, can have a nega-tive effect on the cleaning result.

When using cleaning agents andspecialised products it is essential

that the manufacturer’s instructions arefollowed. Only use the product for theapplication described by the manufac-turer, to avoid any material damage orthe occurrence of strong chemical reac-tions such as oxyhydrogen.

The machine is designed only foroperation with water and additive

cleaning agents. Organic solventsmust not be used in the machine, asthere is the danger under certain cir-cumstances of explosion. Although thisis not the case with all organic sol-vents, other problems could arise withtheir use, for example damage to rub-ber and synthetic materials.

In critical applications where verystringent requirements have to be

met, it is strongly recommended that allthe relevant factors for the process,such as cleaning agent, quality ofwater are discussed with the Miele Ap-plication Technology specialists.

If the cleaning result is subject tothese particularly stringent require-

ments (e.g. chemical analysis, spe-cialised processes), a regular qualitycontrol test should be carried out bythe user to ensure that required stand-ards of cleanliness are being achieved.

Please follow the advice on installa-tion in these instructions and the

separate Installation Instructions.

Empty any containers or utensilsbefore arranging them in the ma-

chine.

Do not allow any remains of acidsor solvents, or chloride solutions to

get into the wash cabinet. Similarlyavoid any materials with a corrosive ef-fect.The presence in compounds of any sol-vents should be minimal, (especiallythose in hazard class A1).

Ensure that solutions or steam con-taining acid salts do not come into

contact with the steel outer casing ofthe machine, to avoid any corrosiondamage.

Warning and Safety instructionsAccessories

Use special inserts in accordancewith the instructions provided.

The only accessories to be usedwith the special commercial ma-

chine must be those supplied or ap-proved by MIELE for the specific appli-cation. Consult your dealer or the MieleProfessional department for advice.

Disposal of an old machine

When disposing of an old machinefirst make it unusable. Disconnect,

cut off the cable and any plug from thecable. For environmental and safetyreasons ensure the machine is com-pletely drained of any residue waterand cleaning agent. (Observe safetyregulations and wear safety gogglesand gloves). Make the door lock inoper-ative, so that children cannot acciden-tally shut themselves in. The simplestway to do this is to remove the lockingpin (2 philips screws above the door).Make appropriate arrangements for thesafe disposal of the machine. For tanksystem machines ensure that any wateris emptied out of the tank.

In countries where there are areaswhich may be subject to infesta-

tion by cockroaches or other vermin,pay particular attention to keeping themachine and its surroundings in aclean condition at all times. Any dam-age which may be caused by cock-roaches or other vermin will not becovered by the machine guarantee.

The manufacturer cannot be held re-sponsible for any damage causedthrough non-observance of theseWarning and Safety instructions.

Reactivating the water softenerWhen the k indicator light on the lefthand side of the control panel comeson during a programme the built-inwater softener is depleted and cannotsupply any more softened water. Itmust therefore be reactivated with dish-washer salt as soon as the pro-gramme has finished.

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

Only use special course grained dish-washer salt (granule size approx. 1-4mm), for reactivation, as other saltsmay contain insoluble impurities or ad-ditives which can impair the functioningof the softener.

The salt container holds approx. 2 kgsalt.

Important

If the only reactivation salt available isfine grain, please consult your Mieleservice representative.

Reactivation salt with granules largerthan 4 mm cannot be used.

Never fill the salt reservoir with dish-washer cleaning agent this can lead to– damage to the water softener and– blockage of the salt container filter insert, resulting in a build up of pressure in the salt reservoir.The irritant alkali solution could be ahazard and personal injury could becaused when the salt container isremoved.Make sure that you have picked upthe right packet of dishwasher saltbefore filling the salt container.

Filling the salt container

Unscrew the filter insert from the saltcontainer and remove.

Fill the salt container with granulardishwasher salt and screw the filterinsert back in place.

Reactivating the water softener

29

Position the salt container asfollows:

Remove the bottom basket from themachine.

Unscrew the plastic cap in the baseof the wash cabinet.

Place the salt container on the reacti-vation socket and screw firmly intoplace.

Switch on the machineOpen 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 proceedsautomatically and finishes when the indi-cator light k at the left hand side of thecontrol panel and the "Start" indicatorlight h have gone out.

Then:Switch off the machine.Unscrew the salt container carefully,so that any water pressure that hasbuilt up can be released. Do not useforce. If you cannot uncrew the saltcontainer by hand, contact the MieleService 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 machineis not to be used again for some time.

ImportantThe water pressure (flow pressure at thetake off point) must be at least 2.5 bar. Ifit less than this see "Programming spe-cial functions".

If the flow pressure is below 2.5 bar, orif it fluctuates, the water softener can-not be reactivated in the normal way.After reactivation, salt remains may stillbe found in the salt container.

To use up the salt remains and to washout the water softener, the "reactivatesoftener" programme must be switchedon again.
