 Notes On Pipe Length and 
Elevation 

 

Ensure that the length of the refrigerant pipe, the 
number of bends, and the drop height between 
the indoor and outdoor units meets the 
requirements shown in Table 7.1:

CAUTION

 

Mark the data plate with the Orifice installed 
(for some models).

 

Please purchase the fittings according to the 
requirements in the manual strictly.

 

Refer the diagram when installing. (See Fig. 7.2)

must be less than 

or equal to 20m

 

(65.6’)

 

The drop height 

between two

WARNING

 

 

All field piping must be completed by a 
licensed technician and must comply with 
the local and national regulations.

 

 

When the air conditioner is installed in a 
small room, measures must be taken to 
prevent the refrigerant concentration  in

 

the room from exceeding the safety limit 
in the event of refrigerant leakage. If the 
refrigerant leaks and its concentration 
exceeds its proper limit, hazards due to 
lack of oxygen may result.

 

 

When installing the refrigeration system, 
ensure that air, dust, moisture or foreign 
substances do not enter the  refrigerant

 

circuit. Contamination in the system may 
cause poor operating capacity, high 
pressure in the refrigeration cycle, 
explosion or injury.

 

 

Ventilate the area immediately if there is 
refrigerant leakage during the installation. 
Leaked refrigerant gas is both toxic  and

 

flammable. Ensure there is no refrigerant 
leakage after completing the installation

 

work.
