Multi Variable Air Conditioners Wall Mounted Type Indoor Unit

4.2 The installation of the rear panel

(1) Find the horizontal position by the seton method; since the drainage pipe is on the left
side, it is necessary to adjust the rear panel to make its left side a little bit lower.
(2) Fix the rear panel on the wall by bolts.
(3) After installing the rear panel, pull it by hands to check if it is secured enough. The hang
panel should support the weight of an adult (60kg), and the weight shared by every bolt
should be fairly even.
(4) The diameter showed in Fig.4.2 is 65mm.
