away from the cable from the lightning rod.
•
Noise may heard depending on the electric wave though the cables.
•
Recommend that use a screened or shielded communication cable.
Install the outdoor unit within the angle of 25~55˚ depending on the building
height as below table.
Install the indoor unit away from lighting apparatus using the ballast.
•
If you use the wireless remote control, it may not operate normally.
Do not install the air conditioner in following places.
•
The place where there is mineral oil or arsenic acid.
Those parts may get damaged due to burned resin.
The efficiency of the heat exchanger may reduce or the air conditioner may be out of order.
•
The place where corrosive gas such as sulfurous acid gas generates from the vent pipe
or air outlet.
The copper pipe or connection pipe may corrode and refrigerant may leak.
•
The place where there is a machine that generates electromagnetic waves.
The air conditioner may not operate normally due to control system.

.
•
The length of maximum piping, level difference, the quantity of connectable indoor units,
the installation at the outdoor joints and the outdoor unit combinations are different from
the conventional models.
•
Outdoor joint of gas side pipe should be installed horizontally due to the combination of
variable units when the height of the main pipe is lower than the outlet of the pipe of the
outdoor unit. The Installation of the liquid pipe and high pressure gas pipe are the same.
•
If the pipe length between outdoor units becomes 2m or more, install vertical pipe trap to
prevent oil stagnation in the pipes of the outdoor unit in the end of the module, in case of
the outdoor unit in the end of the module stops operating while part loading operation in
system. (Refer to page 26 for details.)
