Piping for the Calibration Gas

This piping is to be installed between the zero gas cylinder and the ZA8F flow setting unit, and
between the ZA8F flow setting unit and the ZR202G analyzer.
The cylinder should be placed in a case assembly E7044KF or the like to avoid any direct
sunlight or radiant heat so that the gas cylinder temperature may not exceed 40°C.
Mount the pressure regulator (recommended by YOKOGAWA) on the cylinder.
Mount the stop valve or the check valve (recommended by YOKOGAWA) through the nipple
(found on the local market) at the calibration gas inlet of the equipment as illustrated in Figure
4.4. (The stop valve or the check valve may have been mounted on the equipment when
shipped.) Connect the flow setting unit and the analyzer to a 6mm (O.D.) x 4mm (I.D.) (or nominal
size 1/4 inches) or larger stainless steel pipe.
