  INSTALLATION STEPS OF INDOOR UNIT (Cont.)  
 
NOTES: 
a.  Fasten the wall hang bracket to the wall with 
all the 5 (Five) screws supplied with unit.  
  This correct fixation will prevent motion of 
bracket after fixation, which can cause noisy 
unit operation.
 
 
b.  The wall hang bracket must be leveled in both 
horizontal and vertical directions after fixation 
without tilting to the right or lift to avoid water 
dropping from the unit onto the...

Step (8): Passing refrigerant piping, 
electrical cords and drain hose 
of indoor unit through wall 
sleeve. 
 
• Passing refrigerant piping lines 
through the wall sleeve is done before 
hooking the indoor unit body onto the 
top of the wall hang bracket. 
 
• For left piping, hang the unit onto the 
top of the wall hang bracket and 
incline the unit using a tool such as a 
screw driver set between the middle...

15-1   INSTRUCTIONS FOR CONNECTIING REFRIGERANT PIPING LINES  
 
Avoid excessive height difference 
between indoor and outdoor units. 
 
Avoid excessive length of refrigerant 
piping lines between indoor and outdoor 
units 
 - All bends must be considered when 
connecting indoor unit with outdoor unit 
by required length  
  of refrigerant piping lines. 
-  Do not remove the protective caps from 
the couplings until the refrigerant piping 
lines are...

CONNECTING REFRIGERANT PIPING LINES (Cont.)  
INSTRUCTIONS FOR CONNECTIING REFRIGERANT PIPING LINES (Cont.) 
 The minimum radius of bending must not 
be less than 100 mm to avoid damage of 
tubing. 
Once the tubing is bent, the installer must 
not unbend at the same point as this 
causes work hardening of copper tubing 
and makes it more difficult to reshape 
 
Avoid disconnecting refrigerant 
connections after they have been tightened 
to avoid refrigerant leaks. 
 When there is excessive...

• For refrigerant piping lines of length more than 3 meters, add 25 grams of refrigerant per 
extra meter from 3 meters refrigerant piping lines: 
 
Example 1  = For 8 meter lines, refrigerant added   = (8-3)  x 25  = 125  grams. 
 
Example 2  = For 12 meter lines,...
