3.6 Fundamental safety and accident prevention regulations
Note
The following safety instructions aim to protect operating personnel as well as third
parties and the Multiwasher itself.
Please take note of the information in these instructions and the signs on the Multi-
washer.
However, safety can only be guaranteed during operation if all necessary measures
are taken.
The operator of the machine has an obligation of care to ensure that these
measures are planned for and also to check that they are correctly implemented.
The operator must ensure in particular that:
• The Multiwasher is only used in accordance with its intended purpose. In the
event of the machine being used or operated contrary to this, damage or risks
may arise.
• In order to guarantee functionality and safety, only original spare parts supplied
by the manufacturer may be used.
• The safety of the Multiwasher is not impaired by the subsequent installation of a
dosage system.
• Only appropriately qualified and authorised personnel operate, maintain and
repair the Multiwasher.
• No one sits or stands on the open door.
• Staff are regularly trained in all questions relating to occupational safety and
environmental protection and are familiar with the operating instructions and, in
particular, the safety information contained therein.
• The area around the machine is assessed with reference to the risk to other
people, e.g. children; people with physical, sensory or mental impairments;
people lacking in knowledge or experience. In case of doubt, special optional
initiation functions other than conscious, intentional operation (i.e. operation
from the screen) are to be deactivated.
• The Multiwasher is only operated in perfect, functional condition, all protection
devices and cover panels are installed.
• The safety and switching equipment are regularly tested to ensure they are
functioning correctly.
• Multiwasher which are accessible from the rear may only be operated with rear
panel cladding.
• The required personal protective equipment is made available to and worn by
maintenance and repair personnel.
• A functional test on all machine safety systems is carried out at every regular
maintenance appointment.
• None of the safety and warning notices affixed to the Multiwasher itself are re-
moved and all are legible.
• Upkeep (maintenance and inspection) is carried out on optional vendor parts
according to the requirements in the corresponding instructions.
• Following installation, commissioning and handing over of the Multiwasher to
the customer/operator, no modifications are made (e.g. electrical or mechanical
machine components).

Information on cleaning the surrounding area
When cleaning the surrounding area, the machine can be damaged by aggressive
external influences (fumes, cleaning substances (detergents)) or the ingress of wa-
ter.
• Do not use aggressive detergents (e.g. aggressive tile cleaner).
• If installed at ground level, never allow the surrounding area to flood.
Information on electrics and electronics
Depending on requirements, the Multiwasher is to be connected to a three-phase
(400 V) earth wire system. There is a risk of fatal injury if exposed, electrically
charged components or cables are touched.
• Please take note of the warning information in these instructions and the signs
on the Multiwasher.
• For all work on electrical components in the machine, ensure that the electrical
connections are physically secure.
• For all work on electrical components in the machine, check the wires and ca-
bles for any possible damage and replace, if necessary.
Incorrect cleaning can cause damage to the electronics.
• The Multiwasher, switch cabinets and other electrical components must never
be sprayed with a hose or high pressure cleaner.
• Make sure that no water can enter the machine unintentionally.
Information on non-ionising radiation
Non-ionising radiation is not produced intentionally but unfortunately comes about
due to electrical operating equipment (e.g. electrical motors, high-voltage cables
and magnetic coils). In addition, the machine has no strong permanent magnet.
3.7 What to do in the event of an emergency
In emergency situations, rapidly switching off the machine will help prevent personal
injury or material damage.
• Disconnect the Multiwasher from the power supply using the locally available
mains switch.

4 Product description
4.1 Functional description
The TopClean 60 is a cleaning with a square rack.
The Multiwasher has one wash and one final rinse cycle. A temperature regulator
maintains the set wash temperature of 74°C.
A rotary pump circulates the water from the wash tank into the wash nozzles. The
water jets hit the wash ware from different directions. This ensures uniform washing
results.
The wash cycle is followed by a fresh water final rinse. The items being washed are
rinsed with hot fresh water at 83°C via a separate nozzle system. This heats up the
wash ware for the following drying process.
At the same time, the final rinse water is used to regenerate the rinse water; this re-
duces the degree of soiling of the rinse water.
4.2 Type label
The rating plate is located on the inside of the front panel. Additional rating plates
are located on the switch cabinet behind the front panel, and on the separate GiO
MODULE (if it is part of the Multiwasher).
The following information can be found on the rating plate:

Design and construction subject to change without prior notice!
4.3 GiO-MODULE
The module works according to the principle of reverse osmosis. Raw water is
pressed by a pump through a semi-permeable membrane. The membrane lets only
water molecules through. The hardness components and salts (lime scale, etc.) con-
tained in the water are held back. The clean water (permeat) is brought to the Multi-
washer; the materials held back (concentrate) are brought to the drain.
4.4 Blue operating concept
1 AktivPlus filter
The parts of the Multiwasher that must be touched by the operator in operation and
in daily use are blue. And so after a short briefing, operators know intuitively that
they have to remove and clean the wash system, tank cover sieve and filter, for ex-
ample.
4.5 Dosing equipment
x
Caution
Reduced durability of dosing units and other cleaning and disinfection com-
ponents
The use of inappropriate detergent and rinse aid can corrode the dosing units and
other machine components.
• If necessary: Consult with MEIKO and the detergent supplier.
Note
Information on cleaning chemicals, see chapter “Choosing the right cleaning agent
and rinse aid” on page 30.
Detergent dosing
The detergent dosing unit is designed for the automatic addition of liquid alkaline
detergent to the clean water (manual addition of detergent products is not recom-
mended).
The detergent is transported from the storage container to the wash tank via a
conveyor pipeline. The dosing equipment is self-priming. Dosing occurs during
each filling cycle and at the beginning of each programme cycle via timer control.
Normally, a dosing of approx. 2 ml of detergent per liter of tank water is the correct
concentration. This can be increased/reduced acc. to the water quality, items to be
cleaned and degree of soiling to 5 ml/l or to1 ml/l.

Operating instructions, Multiwasher
TopClean 60
Product description
9018125 19 / 62
Design and construction subject to change without prior notice!
Rinse aid dosing
The rinse aid dosing unit is designed to automatically dose the rinse water with liq-
uid acid rinse aid.
The rinse aid is pumped out of the storage container into the rinse water boiler
supply line through a conveyor pipeline. The dosing equipment is self-priming.
Dosing takes place for each full cycle and each programme cycle.
The correct dosage leads to an even water film.
In case of overdosing, bubbles and stripes will form, which means that the dosage
needs to be reduced.
In case of under-dosing, water drops remain on the washware which means that
the dosage needs to be increased.
Dosing equipment lifetime
The components of the dosing system are subject to high demands:
• Exposure to high concentrations of cleaning products
• Mechanical strain from peristalsis (e.g. by the peristaltic tube)
• High (ambient) temperatures
• Long operating hours
It is therefore essential that the operator has these parts (i.e. wear and tear parts)
checked and serviced regularly. However, it is extremely difficult to prescribe exact
life spans when the parts will need to be replaced since conditions differ greatly
from machine to machine.
The materials found in the dosing system and especially in the peristaltic tubes are
not suitable for use with all detergents and rinse aids available on the market. In
certain cases, they must be adapted to the relevant conditions. This will require
agreement from the Service Technician (MEIKO authorised) or the detergent sup-
plier.
This maintenance guideline (see page 49) is therefore simply a non-binding rec-
ommendation.
Example image of dos-
ing equipment with peri-
staltic tube
4.6 Disinfection control
MEIKO offers two types of machine with thermal disinfection for institutions with ad-
ditional hygiene requirements. Both versions have greater heating performance in
the wash tank than standard machines.
A0control
The term A0refers to a way of measuring how microorganisms are eliminated by
moist heat disinfection methods. By using a moist heat disinfection method, it is ex-
pected that a specific temperature over a period of time has the effect of eliminating
a predictable number of microorganisms with a particular resistance.
The standard setting for a dishwasher with A0– control is the hygiene value A060:
• The tank temperature during washing is up to 74° C.
• For tank temperatures of 65° C or higher, each tank temperature is assigned a
factor.
• Using the measured tank temperature, a value is determined and added every
second until the hygiene value A060 is reached.

• The rinsing process runs until the end of the programme cycle time, but at least
until the temperature value is reached. After this comes a pause for draining
and the final rinse.
The display shows the current A0 value.
Thermal disinfection - control
Thermal disinfection works according to the same principle as Thermolabel control,
but other requirements apply:
• The disinfection temperature is ≥ 80° C, which must be maintained on the
washware for ≥ 30 s.
• During washing, the tank temperature is heated up to 76° C, and the final rinse
temperature is 88 °C.
• The rinsing process runs until the end of the programme cycle time, but at least
until the temperature value and specified stop time are reached. After this
comes a pause for draining, final rinse and a subsequent application time.
Thermolabel and thermal disinfection control offer a disinfection effect that exceeds
the standard, such as for hospitals, care homes, requirements according to the
ÖGSV Guideline.
