Page 14: Installation And Wiring
The PUS400G must be installed in a place where a humidity of 5 to 90% HR is maintained. Avoid installing the ultrasonic oscillator in a place where a high or low humidity is maintained for a long time. It is recommended to always operate the PUS400G at a humidity of 25 to 85% RH. •... -
Page 15: Installing Procedure
Hardware corresponding to the type of mounting used is required to install the PUS400G. Mounting hardware is attached only when requested. In the case of PUS400G-NN-KC (for Korea), a noise filter assembly is attached. Please refer to a figure of external dimensions for the attachment means of the noise filter assembly. - Page 16 < 2. Installation and Wiring > Pipe Mounting When mounting the PUS400G on a pipe, install a pipe (2-inch, OD: 60.5 mm) in the vertical or horizontal direction. Figure 2.4 illustrates the installing procedure for the ultrasonic oscillator using pipe mounting bracket.
