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
holding 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.
