Step one: Choosing installation location
Recommend the installation location and confirm it with 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 specifications of drill head
should be 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 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.
Step three: Open piping hole

position of piping hole should be a little lower than the wall-mounted frame, shown as
