• Fix the power connection wire and signal control wire with wire clip.
Notes:
• After tightening the screw, pull the power cord slightly to check if it is solid.
• Never cut the power connection wire to extend or shorten it.
Step 6: Pipe arrangement
• The pipes should be placed along the wall, slightly
bent and if possible be hidden. The minimum
bending semi diameter is 10 cm.
• If the outdoor unit is higher than the wall hole,
you must set a U-shaped curve in the pipe before
pipe goes into the house, in order to prevent rain
from getting in.
