NOTES!
①
Before installation, please finish the preparation work of all pipes (connection pipe, drain pipe)
and wires (wired controller wire, connection wire of IDU and ODU) that need to be connected
with the indoor unit.
②
Punch holes on the ceiling (air return opening or air outlet). Ceiling may have to be
strengthened to make it level and to prevent it from vibration. You may consult user or
constructor for details.
③
If the ceiling is not strong enough, you can install a beam bracket in a corner and secure the
unit on the beam.

After the indoor unit is installed, remember to check the horizontal status of the whole unit. It should
be horizontal from front to back and slant 1% from left to right, following the drainage direction, as shown
