5.1 Obtain Design Drawing and Report
During the design of MDS system by using the selection software, the user will draw the equipment layout on the
software workplace. After completed the drawing, the software will select the appropriate outdoor model base on
the user requirement. Once all this is completed, user will be able to generate the report. The system layout and
report is necessary in order to have a smooth running commissioning process.
