down may result.
Warning:
The unit must be securely installed on a structure that can sustain its
weight.
If the unit is mounted on an unstable structure, it may fall down and cause
damage or injuries.
The unit must be installed according to the instructions in order to mini-
mi e the risk of damage from earthquakes, typhoons, or strong winds. An
incorrectly installed unit may fall down and cause damage or injuries.
Caution:
Install the unit on a rigid structure to prevent e cessive operation sound or
vibration.
Warning:
When installing or relocating, or servicing the outdoor unit, use only the speci-
ed refrigerant (R 10A) to charge the refrigerant lines. Do not mi it with any
-
other refrigerant and do not allow air to remain in the lines.
If air is mi ed with the refrigerant, then it can be the cause of abnormal high pres-
-
sure in the refrigerant line, and may result in an e plosion and other ha ards.
The use of any refrigerant other than that speci ed for the system will cause
mechanical failure or system malfunction or unit breakdown. In the worst
case, this could lead to a serious impediment to securing product safety.
The thicknesses listed in the table above are based on apanese stand-
ards. Use pipes with a ma imum working pressure of .1 MPa 601 PSI
or higher according to local standards.
