46 Service Manual SM-MDS_(ii)
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.
5.2 Check Piping Routing, Wiring Routing & Connection
After obtaining the design drawing and report, we will need to check on the piping and wiring connection.
Although this should be done during installation, it is better to check all items again before commissioning.
Ensure both liquid and gas pipe are insulated according to the specification stated below. For hot
and wet environment, it is recommended to increase the insulation thickness. If there is special
request due to customer requirement or country regulation, please follow the specification stated.
Ensure that the orientation of the EXV box is in vertical condition.
