2-2-1 : Piping considerations
Introduction
Piping method depends on such conditions as transmitter position and pipeline
installation. It is generally sufficient to use a 3-way manifold valve and connect an
extension pipe.
Since the model JTD720A has separate connector ports for high and low pressure,
distinguish them correctly for installation work. A 3-way manifold valve is optional.
