-2- INSTALLATION INSTRUCTIONS
-2-1. LINE PRESSURE
A 2-bar minimum pressure is absolutely necessary to provide a normal efficiency of the control valve.
Maximum pressure must not exceed 8 bars, in order to prevent troubles on all installation.
If necessary, a pressure regulator should be installed upstream to the system.
If water line is shut down, take care to prevent any depression (negative pressure), which could
destroy the tank. Isolate the system with the bypass or with shut off valves on the inlet and outlet of the
system.
-2-2 ELECTRICAL SUPPLY
If the valve is powered by a low voltage transformer, make sure that the power outlet cannot be
switched off accidentally. Use only the power supply delivered with the valve.
Make sure that the electrical line is protected by a suitable protection
If the electrical cable or the transformer housing is damaged, it must be replaced by a qualified
person.
-2-3 WATER SUPPLY
Existing water line should be clean and neat, free from lime scale and iron. It should comply with
current regulations. Make the necessary changes to prevent troubles. Connection to drain should not
exceed 2 meters above the valve, and total length should not exceed 5 meters.
It is strongly recommended to install a pre-filter upstream to the system.
-2-4 BYPASS
It is strongly recommended to install a bypass on the system if the valve does not include one from
manufacturing
-2-5 TEMPERATURE
Air and water temperature should not exceed 45°C.Temperature should not fall below 1°C. Freezing
can break or strongly damage the equipment and cause major water leaks.
-2-6 INSTALLATION OF THE SYSTEM
Install the system and its brine tank, shielded from the rain and from an excessive humidity on a
flat, solid, horizontal and smooth floor.
Connection of equipment to water line should be done by a qualified person, according to current
applicable regulations.
During installation, brasing operations should be made with no equipment in place. Excessive heat
can cause several damages to the equipment.
The brine tank overflow outlet must be connected to the sewer system.
