◆Installation Services—Install Indoor Unit 
Notes: 
If the connecting cable is not long enough, please contact the designated service station for a piece of 
special cable with sufficient length. No joints are allowed in the middle of the cable.   
  Be sure to connect the cable correctly. Incorrect connection will cause fault to some electrical parts. 
  Tighten the terminal screw to avoid looseness.   
  After tightening the screw, gently pull the cable for tightness.   
  Incorrect connection of earthing cable might cause electric shock.   
  Be sure to fix the junction cover plate securely and press it closely against connecting cable. 
Improper fixing of junction cover plate might allow dust or water to enter or expose connecting 
terminal directly under the external force, whereas fire or electric shock might occur.   
 
Installing Indoor Unit 
  Fitting pipe can come out from four directions, i.e. right, 
rear right, left and rear left. 
 
1.  When laying the pipe (line) at the left or right side, cut as 
needed the extra part of the fitting pipe left at the 
tube-exit plate of the unit base. (See Fig. 9). 
(1)  When only drawing out the power line, cut extra part 
1. 
(2) When drawing out the connecting pipe and the 
electrical line, cut extra parts 1 & 2 (or 1, 2 & 3); 
2.  Pull out the fitting pipe from bottom case. Use adhesive 
tape to bondage the fitting pipe, electrical cable and 
drain hose properly and then pass them through the 
fitting pipe hole (See Fig. 10).   
3.  Hung the claws at the rear side of the indoor unit to the 
hook on the wall-mounting frame. Move the unit left and 
right to see if it is steady. (See Fig 11) 
4.  The installation height of the indoor unit must be at least 
2.4m. 
 
Installing Connecting Pipe 
 
1.  The taper end of the connecting pipe must be in line 
with the corresponding tape face of the valve joint.

Notes: Connect the connecting pipe to the indoor unit first and then connect it to the outdoor unit. Pay 
attention to the bending and layout when preparing the connecting pipe in order not to harm it. Do 
not screw the joint nut too tightly, otherwise leakage will be caused.
