9.2 ANTI-SCALE PRODUCT
9.2.1 Storage
Keep the container hermetically sealed, store it in a dry place where it is protected from sunlight. Optimum storage temperatures are
from +5° to +25°C. Storage duration in the original containers is indicated on the label. We recommend you performing "first-in - first-
out" stock management.
9.2.2 Composition/information on ingredients
Dangerous ingredients: Citric acid
Contents: 10-20%;
CAS Number: 77-92-9;
R Phrases Xi, R36
9.2.3 Danger identification
The liquid is irritating for the eyes.
9.2.4 First aid measures
• In case of contact with the eyes rinse thoroughly with abundant water and consult a physician. Containers of lukewarm water
should be kept on hand (if need be).
• In case of contact with the skin wash with abundant water and remove damp and contaminated garments.
• In case of inhalation: no particular safety instructions.
• In case of ingestion: rinse out the mouth and drink lots of water. DO NOT cause vomit. Consult a physician.
9.2.5 Fire-fighting measures
Water is the best means for fire extinguishing fire. No liquids are known which, for safety reasons, must not be used.
9.2.6 Measures in case of accidental spillage
Cleaning and collection methods:
Large quantities: do not discharge into canals, surface waters or water-
bearing strata. Collect with suitable absorbent materials. Dispose of the

9.2.8 Disposal considerations
Comply with local conditions when disposing of the liquid. 320 grams of 50% potassium hydroxide are required for each kg. of
product to obtain a pH of 7-8.
Dispose of contaminated packing by emptying it as much as possible and then rinsing it. Now the packing can be disposed of as
normal household waste or can be collected for recycling.
9.2.9 Quantity of anti-scale product to be used
The pumps that introduce anti-scale product into the wash water have performance values that average around 1.7 ml/second. This
means that 1.7 ml of liquid is diluted in the water for every second of operation.
For example if there are 6 liters of water and the hardness of the water suggests using 1 ml/l concentration then dosage must be
equal to 6 ml of liquid. Consequently the anti-scale pump must be programmed for an operation of approximately (6/1.7=) 4 seconds.
The required concentration depends on the hardness of the water according to the following table:
(French degree)
(German degree)
(time in seconds for 6 liters of water)
