2. Fix the power connection wire and signal control wire with wire clip (only for
cooling and heating unit).
Note:
● Never cut the power connection wire to prolong or shorten the distance.
During heating operation, the condensate and
defrosting water should be drained out reliably
through the drain hose. Install the outdoor
dr
ain connector in a Φ

hole or Φ

hole on
the base plate and attach the drain hose to the
connector so that the waste water formed in
the outdoor unit can be drained out. The hole

Whether to plug other holes will be determined
by the dealers to actual conditions.
