Tank To Be Used As Replacement Part On Vff4 40 And Vff4 60 Vsd Pumps. The Vessel Ensures The Pump Can Switch Off If There Are Small Leaks On The System. The Air Pressure Must Be Maintained At 60% Of Set Water Pressure To Ensure Correct Operation.
I bought three of these lights and so far, they have delivered beyond my expectations. The auto function enables the light to self-adjust the illumination during the dark hours and the brightness is still very good at 5am just before the sun comes up. Real value for money and I'll be purchasing again.
Excellent product. Easy digital display. The function to change the switch on bar above the normal 3 bar of other makes is very useful.
The pressure in my house is now sorted.
