1 - THE ENERGY LABEL
1.1. - What you must know
Washing machine, dryer and dishwasher are three
appliances likely to weigh heavy on the electricity invoice if
you choose model poorly classified from the energetic
point of view. Washing machine and dishwasher each
consume about 250 kWh a year. For a few years, the
manufacturers have made efforts on the water
consumption, which has a direct effect on the power
consumption at the moment of the heating.
Initiated by the European Community, this labelling is now
compulsory in France for most household electrical
appliances. The classification from A(the most
economical) to G(the most avid on electricity), enables the
consumer to locate at a glance, the various models
proposed.
For washing machines, an additional indication concerning
the wash and spin, complements the information
concerning the power consumed.
This mention must appear compulsorily on all the
dishwashers marketed from the 1st of January 2000.
The “Bio” program is selected to laboratory tests.

2.1. - The customer's expectations
•Perfectly clean dishes
•Dry dishes
•Sparkle of glasses and stainless steel
•Respect of delicate dishes
•Rapidity
•Easy to use
•Low sound level
•Low consumption (water, electricity and products)
2.2. - The advantages of the dishwasher
A family of four persons devotes 55 minutes a day on average to do dishes, against 20 minutes when
it has a dishwasher.
The cost of a dishwasher is written off in only 3 years and its estimated lifetime is approximately 10 years.
Washing up in machine is much more hygienic because dishes are perfectly washed and dried
without contact with external elements (towels, hands or work surface), which often convey a number
of bacteria.

2.3. - The sound level
Noise remains a selection criterion essential despite the fact that indicating it on the "Energy Label" is
not compulsory.
For the HERAKLES dishwasher, the level is comprised between 41 and 50 decibels (dB). It must be
known that a variation by 3 decibels multiplies by two the sound volume and this is only below
50 decibels that the dishwasher can be operated late at night.
To achieve this result, several improvements have been made to the ATLANTIS dishwasher:
•PTC and double auxiliary winding for certain asynchronous cycling pumps
•Reinforced acoustics (double-thickness bitumen, felts, phonic seals)
•Passage of the entire spraying circuit in the tank.
2.4. - The drying
The drying result is an important point that appears on the "Energy Label".
The HERAKLES dishwasher proposes 3 marks for the drying (A/B/C), according to the dishwasher
level of equipment.

2.5. - Operating principle
Dirt adheres to dishes with a certain energy that is to be overcome to get rid of it. It is, therefore,
necessary to implement the following actions:
¾The mechanical action (aspersion)
Its purpose is to project the detergent bath onto dishes to remove and drag the dirt.
The ATLANTIS dishwasher is provided with 4 spraying levels:
•Two that spray the lower and upper baskets
•A third one, multidirectional (small shower) attached to the tank ceiling prevents residues from
depositing on the tank ceiling and falling during drying
•A fourth one, carried out using a rotary nozzle assembled to the lower winch in certain models, is
used to better clean the bottom of saucepans (it is associated to a specific program).
Spraying the dishes is performed by the winches, which turn simultaneously or not (alternate spraying)
under action of the water pressure in spraying nozzles. The water thus projected onto dishes falls in
the tank bottom where it is purified by flowing through four filters. These filters perform continuous
recycling of the detergent solution until cycle end.
The water is then returned, pressurized, by the circulation pump (approximately 50 liters / minute) into
the spraying arms. Such a circulation and the low volume of the cycling unit volume (1.85 liters) are
used to have a total water consumption relatively low (12 liters), as each piece of dishes is washed by
only one volume of water (approximately 4 liters).
After wash, the wastewater is evacuated, the clear water, cold for the first rinse rinses dishes, and
then a second rinse, hot, precedes the drying.
¾The thermal action
The progressive temperature rise and the achievement of an enzymatic dwell at 50°C are used to
obtain the best conditions of elimination of all the types of dirt. Actually, the action of the various
components of detergent products varies according to the bath temperature.
¾The chemical action
When dishes are done in machine, the mechanical action is limited (as compared with dishes done by
hand), and must therefore be compensated for by a more powerful chemical action.
To the mechanical and thermal energy of the machine are added the physical-chemical and biological
actions of the detergent.
As the nature of dirt is very varied, it is not always eliminated in the same way.
This is the reason why detergents contain very different components and, in particular, enzymes.
¾The duration.
All is not as simple. If we detail the operation, we remark that an essential element is missing: the
water. Actually, without water, there is no wash! The water will, with the support of active principles of
the detergent, destroy, eradicate, dissolve and emulsify the dirt present on dishes.
It will do so all the better since the machine will water the dishes and heat the water.
The wash result depends, therefore, simultaneously on 4 factors:
•The washing product
•The water
•The temperature
•The mechanics
A good wash result can, therefore, only be obtained if all these conditions are respected.
Spraying arms project onto dishes (mechanical action) a solution of detergent
products (chemical action) progressively heated by a resistor (thermal action)

THE WATER

LA3P-HERAKLES-001UK-0306
3 - WATER
3.1. - The noxious effects of limestone
Any water contains traces of minerals, mainly limestone, magnesium and iron originating from the
ground. The higher the content is, the harder the water is. These minerals reinforce the dirt catch to
fabric fibers, and the eliminated one tends to be fastened again to them. Limestone reduces the
efficiency of the washing product, makes the laundry rough, makes whites turn grey, fades colors and
accelerates the laundry wear.
3.2. - The water softening: a vital function
The system water contains soluble calcium hydrogen carbonate. Hot, the calcium hydrogen carbonate
decomposes and gives insoluble calcium carbonate (fur).
The water softening is, therefore, a vital function.
This is the reason why all dishwashers are fitted, from the
origin, with water softeners.
Softening is, in fact, the substitution of calcium ions
contained in the system water by sodium ions contained in
the salt.
To perform this substitution, the water is circulated in the
heart of the softener that contains small balls of synthetic
resin.
Combined with sodium, this resin sets the limestone particles
(calcium or magnesium) contained in the system water. To
do so, the resin exchanges its sodium ions for the calcium
ions.
After a certain number of fillings, resins are more or less
saturated with limestone and start becoming ineffective to
soften the water. It is then necessary to regenerate them.
3.3. - The regeneration
To regenerate the resins, it is necessary to eliminate the
limestone from them with sodium (salt).
This regeneration, automatic and "floating" on "all
electronic" ATLANTIS dishwashers, is initiated by the board
according to the adjustment performed on the putting into
service and to the number of filling baths already performed.

3.4. - The pH (hydrogen potential)
Maybe, you have already remarked on labels of cleaning products or drinks the pH indication followed
by a number. Maybe, you know that the pH is related to the acidity of a solution, sometimes verifiable
by its taste. If you taste successively lemon juice, coffee and water, you will be able without any
difficulty to rank these three liquids by level of acidity.

Chlorydric acid Coca-cola Vinegar Beer Milk Sea water Concentrated Bleach Sink caustic cleaner Tape water
The pH paper is used for approximate, simple and rapid determination of the pH of a solution.
This paper, which does not provide exact determination of a value of pH, rather gives an idea of the
pH range of the solution, namely:
•Acid for a pH smaller than 7
•Neutral for a pH equal to 7
•Basic or alkaline for a pH greater than 7
Water, mineralized or not (and, therefore, salt water) has a pH very close to 7.
3.4.1. - A few acids
•Vinegar (acetic acid)
•Aspirin (acetylsalicylic acid)
•Lemon guise (citric acid)
•Coffee
•Vitamin C (ascorbic acid)
•Dishwasher rinsing product
3.4.2. - A few bases
•Household cleaning products (ammonia)
•Soap (potassium hydroxide)
•Concentrated bleach
•Sink caustic cleaner (sodium hydroxide)
•Detergent products for washing machine and dishwasher
Alkaline pH is necessary for the washing bath to ensure maximum efficiency.
3.4.3. - Analysis of traces or deposits on dishes
Replacing a component supposed defective does not constitute the essentials of the maintenance of
a dishwasher. A dishwasher, for which the consumer signals a bad wash result, cannot be repaired so
easily. Actually, to solve this type of claim, it will always be necessary to precisely identify the nature
of the trace or residue present on the piece of dishes. Only this precise identification can indicate us
the probable cause at the origin of the defect.
The matter is not to precisely measure the pH but simply to detect the origin of the white traces or of
the residues.
So, when the paper turns red we are in the presence of an acid solution (rinsing product for example),
if it turns blue, then it is an alkaline solution (washing product).

4 - THE DETERGENTS
4.1. - The products
4.1.1. - The detergents
Contrary to many received ideas, all detergents are not identical. They contain specific ingredients. So
each type of detergent has its own features and will be particularly suited to such or such type of wash
or of dishes.
•Detergent products are alkaline.
•They have, therefore, a pH comprised between 9 and 11.
•They are classified IRRITATING.
¾The powder
It is perfectly efficient under difficult wash conditions (very hard water or very dirty dishes) and is
suitable for washing silver and decorated glasses.
¾The tabs
The dosage ease certainly explains the development of their market share. The dissolution time can
vary from 10 seconds to over 10 minutes. When selecting a fast or short program, it's better to use
powder.
¾The liquids
It is particularly more suitable for fragile dishes and respects the decoration.
4.1.2. - The rinsing product
It enables water to flow more rapidly and more completely from dishes, so preventing the formation of
traces during drying. It neutralizes alkaline residues of the detergent during the final rinse and favours
the drying of dishes. Its acid pH is comprised between 1 and 3. It must be compatible with the
detergent (it is preferable to keep the same product trademark).
4.1.3. - The regenerating salt
It is used to regularly regenerate the water softener resins. It protects the appliance and dishes from
layers of sediment. Its pH is neutral and equal to 7.
4.1.4. - The "all-in-one" products
New products integrate in one and the same dose the 3 functions essential to the right operation of
the dishwasher:
•The wash function
•The salt function
•The rinse function
In cases of hard and very hard water (hardness greater than 35°TH), it is indispensable to use
regenerating salt. Some manufacturers specify that the wash must be done at 50°C maximum under
penalty of freeing too early the various actions of the product and altering the final result, or even
damaging some pieces of dishes.
