Appropriate use
7
The PLW 8615 and PLW 8616laboratory washers are designed to re-
process laboratory glassware, utensils and similarly categorised com-
ponents using water-based media.
Appropriate use
Reprocessing encompasses the cleaning, rinsing, and – where ne-
cessary – thermal disinfection and drying of the following load:
- Vessels such as beakers, flasks, cylinders and test tubes
- Measuring vessels such as measuring cylinders, volumetric flasks
and pipettes
- Dishes such as petri dishes and watch glasses
- Plates such as slides and sequencing plates
- Small items such as lids, magnetic stirring rods, spatulas and stop-
pers
- Other items such as boxes, plastic flasks and containers, metal
parts, pipe and hose pieces and funnels
The laboratory washers are generally referred to as “machines” in
these operating instructions. The term “load” is used wherever the
items to be processed are not defined in any further detail. The term
“wash water” is used for the mixture of water and process chemicals.
Reprocessing is carried out in conjunction with:
- Process chemicals which are tailored to the result of the repro-
cessing
- Load carriers which are tailored to the load
Observe the information issued by the manufacturer of the load.
Inappropriate use
PLW 8615 and PLW 8616 laboratory washers may not be used for
any purposes other than the appropriate use described. This applies
in particular to:
- The reprocessing of medical devices that can be reprocessed
- Use in the catering industry
- Domestic use

Warning and Safety instructions
19
Risk to health and risk of damage if the operating instructions
are not followed.
Failure to follow the operating instructions – and in particular the
safety instructions and warnings they contain – may result in per-
sons being seriously injured or property being seriously damaged.
Read these operating instructions carefully before using the ma-
chine. This will prevent both personal injury and damage to the ma-
chine.
Keep the operating instructions in a safe place.
Correct application
 Use of the machine is only permitted for the applications expressly
approved in the operating instructions. Alterations or conversion of
the machine, or using it for purposes other than those for which it
was intended, are not permitted and could be dangerous.
The cleaning and disinfection processes are only designed for labor-
atory glassware and utensils which are designated as reprocessable
by the manufacturer. The information provided by the manufacturer of
the load items must be observed.
 This machine is intended for indoor use only.
 The machine is equipped with a special bulb to cope with particu-
lar conditions (e.g. temperature, moisture, chemical resistance, abra-
sion resistance and vibration). This special bulb must only be used for
the purpose for which it is intended. It is not suitable for room light-
ing. Replacement lamps may only be fitted by the Miele Customer
Service Department.
Risk of injury
Please pay attention to the following notes to avoid injury
 This machine must be commissioned, serviced and repaired by a
Miele authorised and trained service technician only. To ensure com-
pliance with Good Laboratory Practice guidelines, Miele repair and
maintenance contracts are recommended. Unauthorised repairs can
pose considerable risks to the user.
 Do not install the machine in an area where there is any risk of ex-
plosion or of freezing conditions.
 The electrical safety of the machine can only be guaranteed when
it is correctly earthed. It is essential that this standard safety require-
ment is observed and regularly tested. If in any doubt, please have
the electrical installation inspected by a qualified electrician.
 A damaged or leaking machine could be dangerous and comprom-
ise your safety. Disconnect the machine from the mains immediately
and call the Miele Service Department.

Warning and Safety instructions
20
 Label machines which have been taken out of operation and se-
cure them from being switched on again without authorisation. The
machine may only be put back into operation once it has been suc-
cessfully repaired by the Miele Customer Service Department.
 Personnel operating the machine should be trained regularly. Un-
trained personnel must not be allowed access to the machine or its
controls.
 Take care when handling chemical agents. These may contain irrit-
ant, corrosive or toxic ingredients.
Please observe the chemical agent manufacturer's safety instructions
and safety data sheets.
Wear protective gloves and goggles.
 The machine is designed for operation with water and recommen-
ded additive chemical agents only. Organic solvents and flammable
liquid agents must not be used in it.
This could cause an explosion, damage rubber or plastic components
in the machine and cause liquids to leak out of it.
 The water in the cabinet must not be used as drinking water.
 Be careful when sorting items with pointed ends. Position them in
the machine so that you will not hurt yourself or create a danger for
others.
 Broken glass can result in serious injury when loading or unload-
ing. Damaged glass items must not be reprocessed in the machine.
 When using this machine in the higher temperature ranges, be es-
pecially careful not to scald or burn yourself or come into contact with
irritant substances when opening the door. Where disinfecting agents
are used there is a danger of inhaling toxic fumes.
 Where there is a risk of toxic or chemical substances occurring in
or leaking into the suds solution (e.g. aldehyde in the disinfecting
agent), it is essential to regularly check door seals and make sure that
the steam condenser is functioning correctly. Opening the machine
door during a programme interruption carries particular risks in such
circumstances.
 Should personnel accidentally come into contact with toxic va-
pours or chemical agents, follow the emergency instructions given in
the manufacturer's safety data sheets.
 After using the hot air drying unit, open the door to allow the
everything in the cabinet from the load itself to the mobile units, mod-
ules and inserts to cool down.
 Mobile units, modules, inserts and the load must be allowed to
cool down before they are unloaded. Any water remaining in contain-
ers could still be very hot. Empty them into the wash cabinet before
taking them out.
