TVN V507 Electrical Float Control Valves ensure that water level of tanks and reservoirs is con¬trolled automatically. Main valve control is established by two-way pilot water gauge. When water level is below adjusting level, valve is opened automatically to fill up the tank. When it reaches the adjusting level, valve is closed automatically to fix the water level.
Place the water gauge properly, paying attention to the tank level. Set the automatic mode for three-way globe valve. Connect the cable of solenoid coil and water gauge to the panel. Drain water to the system.
