•
A water flow in the water supply system may not be lower than 20 litres/minute.
•
With water hardness exceeding 14 °fH (8 °dH), it is recommended to use an
appliance with a built-in water softener. With water hardness exceeding 35 °dH
(19.5 °dH), it is recommended to install an external water softener before the
solenoid valve.
High electric conduction of water indicates a very high concentration of minerals
dissolved in water; in such a case, demineralization device should be installed.
•
Appliances intended for operation with desalted water or water with high
concentration of sodium chloride should be ordered separately, as special
minerals are required for their construction.
•
Appliances equipped with a heat recovery installation with copper tubing may
not be operated with de-mineralized water. In such cases, a version with heat
exchanger with stainless steel tubing should be ordered.
•
Furthermore, when checking the water quality, the pressure of water supply
system must be taken into account. This parameter determines the correct
operation of the appliance.
