INSTALLATION 

1 INDOOR UNIT INSTALLATION 

1.1 Before Installation 

1.

 

The preparation of all pipes (connecting pipes and drainage pipes) and cables (connecting 
lines of wired controller, indoor unit and outdoor unit) must be ready before the installation, 
so as to achieve smooth installation. 

2.

 

Drill an opening on the ceiling. Maybe it is required to support the ceiling to ensure the 
evenness of it and avoid the vibration of it. Consult with the user or a construction company 
for details. 

3.

 

In case the strength of ceiling is not enough, use angle iron sections to set up a beam support. 
Place the unit at the beam and fix it. 

1.2 Installation Site   

1.

 

Ensure the top hanging piece has strong strength to withstand the weight of the unit. 

2.

 

The drainage pipe has convenient flow of water. 

3.

 

There is no obstacle blocking the air intake and exhaust outlet, so as to ensure sound air 
circulation. 

4.

 

The installation spaces required by the drawing must be ensured, so as to provide enough 
space for the service and maintenance. 

5.

 

The installation site must be far away from heat source, leakage of inflammable gas or 
smoke. 

6.

 

The indoor unit is of ceiling mount (indoor unit is hidden inside the ceiling).
