INSTALLATION AND USE
The serpentines preserve the pressure gauge, as they avoid water hammering and decrease the temperature of the fluid, therefore they must be installed before the pressure gauge by connecting them to a pressure gauge tap. To install the coil, use special products to seal the threads, depending on the fluid intercepted and use the key exclusively on the hexagon. To install the pressure gauge, screw it up to the stop, holding the coil with the hexagon at the top. Enter the fluid in the line.
