Check the Layout of the Drain Pipe and Connection Wires

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.
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?
Trial Operation
The person who has completed this installation shall be requested to conduct a test operation
for check:
Is the temperature adjuster working normally?
Does the location for installation conform to requirements?
Winding up with Protective Plastic Tape
The connection pipes, drain pipe, and the connection wires shall be wound up with PVC tape.
Notes: The connection pipes shall also be wound up with insulating material to preserve the
