9) Scale build up
Scale deposits will quickly show on inner components when using hard water, not sweetened with ion exchange resins.
Scale formation increases when the pressure relief valve is used as flow rate regulator: the rate of scale deposition increases with increasing of
closed loop circulation.
Scale deposits cause an increase of torque, occasional seizure of the pump or a reduction of operating pressure because the pressure relief valve
cannot work properly.
To minimize this problem Fluid-o-Tech suggest to use pumps with flow rate matching the hydraulic circuit features.
In some circuits it is advisable to periodically remove scale with a chemical treatment.
INFORMATION FOR USERS
In accordance with article 13 of legislative decree no. 151 "Implementation of directives 2002/95/EC, 2002/96/EC and
2003/108/EC on restriction of the use of certain hazardous substances in electrical and electronic equipment and the
disposal of waste".

it must be disposed of separately from other waste.
Separate collection of this appliance at the end of its working life is organised and managed by the manufacturer.
The user wanting to dispose of this appliance should therefore contact the manufacturer and follow the separate waste collection
system to dispose of the appliance at the end of its working life.
Appropriate separate collection and the subsequent recycling, treatment and ecological disposal of the disused appliance help avoid
possible negative effects on the environment and health and encourage the re-use and/or recycling of the constituent materials.
