Are there any requirements for installing softening unit?

To ensure proper installation you must meet the following conditions: 

1) The water pressure - between 2 and 6 bar (unless the technical information in the Installation Manual says otherwise). System pressure below the minimum will cause a weaker performance and the need for frequent regeneration. For systems supplied with water from their own well it is possible to increase the pressure to a minimum value. If water pressure exceeds the maximum value pressure reducing device should be used. Pressure exceeding the maximum may cause: excessive noise during operation and damages to the system. 

2) Power Source - 230V/50Hz electric outlet (without extension cord). If you need to use an extension cord it should meet the same requirements as the power source.

3) Temperature - The system should be installed in areas not exposed to large fluctuations in temperature. It must be protected from freezing and it must not be installed in outdoor locations or too close to heat sources (stoves, hot water pipes) which can damage the device. Softener should be installed only in areas where the temperature exceeds 4C. 

4) Place the softener as close as possible to the water pomp and drainage (water softener must be installed after water pomp). 

5) Softener should be placed on a flat surface, straight and stable. 

6) Hot water can damage components of water softening system such as: control valve and ion exchange resin. In case of unit installation in close proximity to a boiler and water heater, it is recommended to use control valve such as: check valves. 

7) The installation site should have enough space to accommodate pipes supplying water to the control valve, drain pipes and also to by-pass valve, as well as, to ensure sufficient space for easy access to components during maintenance and possible repairs. 

8) The location of system components should also allow easy access to the brine tank for filling procedure. It should provide enough space over the tank to allow to open the lid of the tank and maneuvers heavy bags of salt. 

9) The brine tank should rest on a smooth flat surface. If surface like that is not available, you should create it using a thick piece of plywood or other material. WARNING! Make sure that the prepared surface is even and stable. 

10) Already positioned water softening unit should not be moved. In order to transfer the unit, always disconnect it from its connections, then move it to a new location (move the unit without water in the tank).
