Installation of indoor unit

Step one: choosing installation location
Recommend the installation location to the client and then confirm it with the client.
Step two: install wall-mounting frame
1. 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.
2. Drill the screw fixing holes on the wall with impact drill (the specification of drill
head should be the same as the plastic expansion particle) and then fill the
plastic expansion particles in the holes.
3. 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 the plastic
expansion particle is loose, please drill another fixing hole nearby.

1. 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-mounted frame,
shown as below.
