CAUTION

The refrigerant R410A requires that strict precautions be observed for keeping the system clean, dry 
and tightly sealed.
Clean and dry
Strict measures must be taken to keep impurities (including SUNISO oil and other mineral oils as well 
as moisture) out of the system.
Tightly sealed
R410A contains no chlorine, does not destroy the ozone layer and so does not reduce the earth’s pro-
tection against harmful ultraviolet radiation. R410A will contribute only slightly to the greenhouse effect 
if released into the atmosphere. Therefore, sealing tightness is particularly important in installation.
Carefully read the chapter “REFRIGERANT PIPING WORK” and strictly observe the correct proce-
dures.

2. BEFORE INSTALLATION

2-1 CAUTION CONCERNING NEW REFRIGERANT SERIES

• Since design pressure is 4.0 MPa or 40 bar (for R407C units: 3.3 MPa or 33 bar), the thickness of pipes 

must be greater than previously. Since R410A is a mixed refrigerant, the required additional refrigerant 
must be charged in its liquid state. (If the system is charged with refrigerant in its gaseous state, due to 
composition change, the system will not function normally.)
The indoor/outdoor unit is designed for R410A. See the catalogue for indoor/outdoor unit models that can 
be connected. 
(Normal operation is not possible when connecting units that are originally designed for other refrigerants.

2-2 PRECAUTIONS

• Hold the unit by the Hanging brackets (4 points) when opening the box and moving it, and do not lift it hold-

ing on to any other part especially the refrigerant piping.

• About installation of outdoor and indoor unit, refer to the installation manual provided with the outdoor and 

the indoor unit.

• This unit, both indoor and outdoor, is suitable for installation in a commercial and light industrial environment.

If installed as a household appliance it could cause electromagnetic interference.

2-3 ACCESSORIES

Check the following accessories are included with your unit.

NOTE

• Do not throw away any of the accessories until installation is complete.
