1. Before the Start-up Operation
1.1. Checking Installation
Before the start-up operation of MP1-200/MT1-200, check the following according to
“MP1-200/MT1-200 Installation Manual.”
a) Unit installation
Ensure that the unit is secured to an appropriate location.
See the section “5. Installation” in MP1-200/MT1-200 Installation Manual for details.
b) Installation of steam pressure sensor
Ensure that the MP1-200 steam pressure sensor is installed correctly to the steam header.
Also ensure that the MT1-200 steam pressure sensor (optional) is installed correctly if it is
used.
See the section “5. Installation” in MP1-200/MT1-200 Installation Manual for details.
c) Wiring
