A1.5 MiniDOS operation
MiniDOS is a self priming pump, it is thus sufficient to draw water from a tap to prime the pump. MiniDOS is a
mechanical pump that doesn't require electrical power supply; the operation is automatically activated by the water
flow. The dosage of AcquaSIL 20/40
peak flow rates (see table in paragraph A1.7). For water flows below the minimum the pump does not operate; for
flow rates exceeding the peak flow rate the dosage of AcquaSIL 20/40

of AcquaSIL 20/40 is not possible. The lack of AcquaSIL 20/40
but it is visible from the emptying and crushing of the tank itself. Check the tank filling degree periodically. When the
filling degree drops below the minimum it is necessary to refill the tank. A prolonged dry running may cause a
temporary blockage of the pump (see A3 troubleshooting); moreover, the missed dosage of AcquaSIL 20/40
not guarantee the protection against scale and corrosion.
A1.6 What's AcquaSIL 20/40
®
AcquaSIL 20/40 is a ready-to-use (do not dilute) aqueous solution of food grade sodium polyphosphates used to
prevent incrustation and corrosion.
Anti-scaling effect: AcquaSIL 20/40

Anti-corrosive effect: AcquaSIL 20/40

®
AcquaSIL 20 / 40 is available in 250 g disposable bags packaged in packs of 4 bags (cod. PC200) or in 1 kg pack bottle
(cod. PC002).
®
Keep AcquaSIL 20/40 in a clean place away from direct sun and heat sources with room temperature ranging from 5
°C and 35 °C. Keep out of the reach of children.

A1.8 Specification for water to be treated
MiniDOS has been designed and created for the treatment of drinking water.
If the water to be treated is not potable please contact Acqua Brevetti S.r.l. (tel. +39.(0)49.8973432, e-mail:

The dosing of AcquaSIL 20/40
The P O concentration in water treated by MiniDOS is lower than 5 mg/l. This value refers to water having, before

MiniDOS cannot be used to treat water containing chemicals of any kind (e.g. acids, bases, solvents, detergents,
antifreezes, glycols, etc.).
