The drain pipe should be placed underneath, and the connection wires should be placed upside;
and the drain pipe especially the section inside the machine and indoors must be wound up with
insulating material to preserve heat. The drain pipe shall be sloped and no concave and convex
shall occur along the whole pipe. And the cases as the right figure indicates shall not occur.
3.Installation check
Is power supply voltage required?
Is water completely drained to outdoors?
Are power wire and connection wires between indoor and outdoor units correctly connected?
Is any gas leaked from the pipe connectors?
Are series numbers of the terminals on the indoor and outdoor units corresponding to each other?
Is the connection section of the auxiliary pipe insulated? Is the indoor unit fixed firmly?
Is noise big?
