Water quality

A cup of coffee consists of 99 percent water. Therefore, the water has a significant effect on the coffee's taste. To obtain an excellent cup of coffee, you need excellent water.

The water is important not only to the taste of the coffee but also to the coffee machine itself. Poor water quality can lead to permanent machine damage.

Therefore, close attention needs to be paid to the water quality in order to obtain high quality coffee and protect the coffee machine.

Water values

Poor water values can lead to machine damage.

It is imperative that the specified values be complied with. Otherwise, Schaerer AG shall not accept liability.

The following water values are a precondition for the correct operation of the coffee machine:

• 4 – 6°dKH (German carbonate hardness)
• 7 – 8°dGH (German total hardness)
  • pH value 6.5 – 7 (pH-neutral)
  • Chlorine content max. 100 mg per litre

Water is referred to as hard or soft depending on its composition. The hardness of water is referred to as its total hardness.

The total hardness is differentiated into carbonate hardness (temporary hardness) and non-carbonate hardness (permanent hardness). In terms of the water hardness, the concentration of bicarbonate anions (HCO3-) is of special significance. The concentration of bicarbonate ions or the equivalent quantity of alkaline earth metal ions is referred to as carbonate hardness.

International conversion table (factors apply to total hardness and carbonate hardness)

Unit		° dH	° eH	° fH	ppm	mmol/l
German hardness 1°dH 1	1.253 1.78	17.8 0.1783
English hardness 1°eH 0.79	8 1 1.43 1	4.3 0.142
French hardness	1°fH 0.56	0.702 1 10	0.1
Part(s) per million (USA)	1 ppm	0.056	0.07	0.1	1	0.01
Millimole per litre	1 mmol/l	5.6	7.02	10	100	1

Acidic	Neutral	Alkaline
0	7	14

If the water values do not correspond to the above-mentioned specifications, the water must be prepared accordingly (decalcification/enrichment with minerals).

The service partner can provide detailed information on filter options and versions and can install this equipment at your location.

Determining the water hardness

A water hardness test must be performed to determine whether a water filter is needed. If the water values are poor, trouble-free operation of the machine cannot be ensured.

The water values must also be entered when the machine is taken into service and can be readily adjusted in the machine menu. On the basis of the entered values, the machine calculates the time to the next filter change (if a filter is in use) and the time to the next decalcification routine.

▶ Check whether a house filter system is already connected upstream from the machine.

In most water, the carbonate hardness is markedly lower than the total hardness. This is a good indicator for determining whether the water is straight from the mains or if it first passed through a house filter system.

Option 1: Requesting information from the drinking water supplier

▶ Ask the local drinking water supplier for information on the water hardness (total hardness) of the drinking water.

Option 2: Performing a test

▶ Determine the water hardness using the test strips included in the scope of delivery.
▶ Dip the test strip into the tap water for ca. 1 sec.
▶ Remove the test strip and wait for ca. 1 min.

☑ The test strips changes colour.

▶ Compare the water analysis result with the "Total hardness" table in the "Water values" chapter.
▶ Install a water filter if the test result is poor.

See "Filter equipment" in this chapter or, for machines that are operated with drinking water, see the chapter entitled "Service and maintenance" - "Installing a water filter for the internal drinking water tank".

Filter technology

To protect the coffee machines and the coffee quality against hard or soft water, filters are used. Filters are essential for the care and maintenance of the machine, not to mention for hygiene, and for the best quality of coffee.

Even when using a filter, it is still necessary to measure the water values once a year. Water is a living element and therefore changes frequently.

The service partner can provide detailed information on filter options and versions and can install this equipment at your location.
