INSTALLATION
INSTALLATION OF INDOOR UNIT
Step 1: Choosing installation location
• Recommend the installation location to the customer and then confirm it with the customer.
Step 2: Install wall-mounting frame
• Hang the wall-mounting frame on the wall; adjust it in horizontal position with the level meter
and then point out the screw fixing holes on the wall.
• Drill the screw fixing holes on the wall with the impact drill (the drill head specification should
be the same as the plastic anchor) and then put the plastic anchors in the holes.
• Fix the wall-mounting frame on the wall with tapping screws (ST4.2X25TA) and then check if the frame
is firmly installed by pulling the frame. If a plastic anchor is loose, drill another fixing hole nearby.
Step 3: Open piping hole
• Choose the position of piping hole according to the direction of outlet pipe. The position of piping
hole should be a little lower than the wall-mounting frame, as shown below.

• Open a piping hole with a diameter of Φ55 mm or Φ70 mm depending on selected outlet pipe.
In order to drain efficiently, slant the piping hole on the wall slightly downward to the outdoor
side with a gradient of 5° to 10°.
NOTES:
• Pay attention to dust and take relevant safety measures
when opening the hole.
• The plastic anchors are not provided and should
be bought locally.
