1.  Determine the route to move the unit to the installation site.
2.  First  unseal  and  unpack  the  unit.  Then,  hold  the  seats  of  the 
hanger  (4  pcs)  to  move  the  unit.  Refrain  from  exerting  force  on 
other  parts  of  the  unit,  especially  the  refrigerant  piping,  water 
discharge piping, and the plastic parts.
1. Before Installation
 
 
 
 
 
 
1.  Choose a site that fully complies with the following conditions and 
user requirements to install the air conditioning unit.
 Well ventilated.
 Unobstructed airflow.
 Strong enough to bear the weight of the indoor unit.
 Ceiling has no obvious slant.
 There  is  sufficient  space  for repair and maintenance work to be 
carried out.
 No leakage of flammable gas.
 The length of the piping between the indoor and outdoor units is 
within the permitted range (refer to  the manual on installation  of 
the outdoor unit).
2.  Mounting height
 The mounting height is 2.5~3.5 metres (2.5~4 metres for model 140).
3.  Mount using the mounting screws.
4.  Space required for installation (unit (mm)):
5.  Based on the shape of the room, determine the airflow directions 
for the  installation  site.  See Figure 2.3  for  the  schematic  on the 
direction of airflow. If part of the air vent must be blocked, you may 
insert an air baffle at the vent of the unit body to block the air flow. 
See Figure 2.4.

3. Indoor Unit Installation
Make sure that only specified components are used for the installation 
works.
3.1 Installation with Lifting Bolts
Use  different  bolts  for  the  installation  depending  on  the  installation 
environment.

•  The air baffle is not included. Please contact the sales agent 
to purchase the wind deflector.
•  The air baffle must be installed in front of the installation panel. 
If  the  panel  is  already  installed,  make  sure  you  remove  the 
panel before you install the air baffle.
