5. Recommended dosage is normally 2-5 g/l.
The used concentration of detergent is related to
- The degree of water hardness
- The degree of uncleanness
- The water temperature
Usually washing temperature should be approx. +50...60
0
C,
With blood washing temperature is lower.

DEKO 260 is designed to operate with potable water (
WHO-Guidelines for drinking water quality
1996 refers
) supplied directly to it, or with potable water supplied to the water treatment equipment
supplying the machine. Water treatment equipment may include e.g. a softener, de-ioniser or
reverse osmosis plant, as necessary. Note that many of the attributes of the water supplied to the
machine can affect the efficacy and/or efficiency of the process. These include hardness, pH,
microbial purity as well as various reactive anions and cations.
Should purified water be required for the process, in addition to the direct supply of potable
water, the machine can be equipped with an additional solenoid valve, and in case of a non-
pressurised supply, also with an extra feed pump. In order to ensure freedom from microbial
contamination, rinse water used in a possible final rinse after disinfection shall be treated as
required. For testing the water quality please see EN ISO 15883-1 Chapter 6.4.

For reference, the quality of water used in the process, excluding any final rinse after disinfection,
the following values were determined during the microbiological type tests:
Conductivity: 16, 4 mS/m
PH: 8,1
Ox disables substances (Red ox potential): UH 482 mV
Total hardness (Salts of Ca
