•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 that they contain.
•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 dishwashing machine is only operated in perfect, functional condition, all
protection devices and covers are installed.
•The safety and switching equipment is regularly tested to ensure it is function-
ing correctly.
•Dishwashers accessible from behind may only be operated with a rear cover.
•The required personal protective equipment is made available to and worn by
maintenance and repair personnel.
•A functional test on all dishwashing machine safety systems is carried out at
every regular maintenance appointment.
•None of the safety and warning notices affixed to the dishwashing machine it-
self are removed 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 dishwashing ma-
chine to the customer/operator, no modifications are made (e.g. electrical or
mechanical machine components).
•Equipment for optimising energy consumption must not be used to lower the
required operating temperatures, as set out in the standards DIN 10510, 10511
and 10512. If equipment for optimising energy consumption is nevertheless in-
stalled, MEIKO does not accept any responsibility for a possible reduction in
the quality of the wash and hygiene.

•Ensure that no water can enter the machine by accident.
Notice on non-ionising radiation
The dishwasher does not specifically generate non-ionising radiation. For tech-
nical reasons, only the electric appliances emit non-ionizing radiation.
In the immediate vicinity of the dishwashing machine, the influence of active im-
plants (e.g. cardiac pacemakers, defibrillators) can be ruled out with a high degree
of probability.
3.7 What to do in the event of an emergency
•In dangerous situations, disconnect from the power supply using the locally
available mains isolator.
4 Product description
4.1 Functional description
The M-iClean H is a hood type dishwashing machine with a square basket.
The dishwasher has one wash and one final rinse cycle.
A temperature regulator maintains the set wash temperature of between 58-60 °C. A
rotary pump circulates the water from the wash tank into the wash nozzles. The wa-
ter 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 80-83 °C (65 °C for the glass programme) via a sepa-
rate 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.

4.5 Blue operating concept
The parts of the dishwasher 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.

4.6 Detergent and rinse aid
Warning
Risk of injury from contact with chemicals
•Observe the safety data sheets and dosing recommendations of the chemical
manufacturers.
•Use eye protection.
•Wear protective gloves.
•Do not mix different chemical products.
Caution
•Only use products that are suitable and approved for commercial dishwashers.
MEIKO recommends MEIKO ACTIVE detergent and rinse aid. MEIKO ACTIVE
products are optimally adapted to MEIKO dishwashing machines.
•Do not mix different cleaning products.
The dishwashing machine is equipped by default with dosing units for dosing liquid
detergent/rinse aid. Manual dosing with powder cleaner is not intended.
Optionally, the dishwashing machine can be equipped with or prepared for an exter-
nal dosing system. In this case, further information can be found on the wiring dia-
gram and in the External dosing document.
4.6.1 Detergent
Detergents are alkaline (pH value should be > 7) and are needed to dissolve soiling
from the washware. The standard setting is 2 ml of detergent per litre of tank water.
If necessary, the concentration can be adjusted depending on the water quality,
washware and degree of soiling. This setting is made during commissioning by an
service technician authorised by MEIKO or the chemical supplier.
Change dosing quantity, see page 51.

9763288
19 / 70
4.6.2 Rinse aid
Rinse aids are acidic (pH value should be between 2 and 7) and accelerate the dry-
ing of the washware by reducing the surface tension of the water so that it can run
off the washware quickly.
The correct dosage is achieved when the water drips evenly from the washware and
depends on the available water quality on-site. This setting is made during commis-
sioning by an service technician authorised by MEIKO or the chemical supplier.
Change dosing quantity, see page 51.
4.6.3 Dosing equipment
The components of the dosing units are subject to high demands and must therefore
be regularly maintained and, if necessary, replaced in accordance with the mainte-
nance specification.
The service life of the dosing units and other components of the dishwashing ma-
chine depends on the use of suitable chemical products. MEIKO recommends
MEIKO ACTIVE detergent and rinse aid. MEIKO ACTIVE products are optimally
adapted to the dishwashing machine.
4.6.4 Suction lances
Suction lances with level monitoring for rinse aid (blue) and detergent (grey)
Suction lances ensure that the liquid chemical product is sucked in correctly. Suction
lances are inserted vertically into the canisters and are optionally equipped with level
monitoring. When the canister is running low, a message will appear on the machine
display.
4.6.5 Change of products
Caution
When changing the detergent product (even to a product from the same
manufacturer), crystallisation may occur, which can lead to failure of the
dosing system.
•When changing the detergent product, flush the dosing system with warm wa-
ter.
Procedure for changing the detergent product:
1. Provide a suitable container with warm water and insert the suction lance.
2. Thoroughly flush the dosing system several times by venting the lines, see
page 54.
3. Wipe the suction lance and put it into the canister with the other detergent prod-
uct.
4. Refill the dosing system by venting the lines.
For dishwashers with an internal reservoir, have the system flushed by a service
technician authorised by MEIKO.

4.7 Options
4.7.1 GiO-MODULE
The module works according to the principle of reverse osmosis. Drinking 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 (permeate) is brought to the dish-
washing machine; the materials held back (concentrate) are brought to the drain.
4.7.2 Automatic hood system
The hood is fitted with an electric motor, removing the need for physical effort when
opening and closing.
Features:
•Closes hood when wash key is pressed
•Closes hood with optional basket detection

•3 pressure levels, see page 37
•Soft start
•Integrated into the following models: HM-PW, HL, HXL-PW
4.7.5 Disinfection control
Caution
Glass corrosion and loss of decorations due to high water temperatures and
long wash cycle times
•Make sure that the dishes and glassware used are suitable for the high stress
placed on them.
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 A030:
•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 A030 is reached.
