NOTICE
• This Application enables the auto-address setup and the test operation of the outdoor unit by smartphone in 48 hours from
the power input to the outdoor unit.
• You should decide whether to make use of this auto-address setup and test operation function at its own responsibility and
also be sure to confi rm notices in the Operating Manual before performing the test operation.
• If you want to disable the function of the auto-address setup and the test operation, perform the following operations.
• Refer to the service manual for setting change of the auto-address setup and the test operation function to be effective.

* Do it again if the 7-segment display is different from the above.
* The functions other than the auto-address setup and test operation of this Application can work normally even
if the auto-address set up and test operation function are disabled.
CAUTION
• High voltage parts exist in the electrical control box.
If you set Switch setting, set it from the access door cover of the electrical control box cover to avoid electric shock.

WARNINGS ON REFRIGERANT LEAKAGE
Check of Concentration Limit
The room in which the air conditioner is to be installed
requires a design that in the event of refrigerant gas
leaking out, its concentration will not exceed a set limit.
The refrigerant R410A which is used in the air conditioner is
safe, without the toxicity or combustibility of ammonia, and is
not restricted by laws to be imposed which protect the ozone
layer. However, since it contains more than air, it poses the
risk of suffocation if its concentration should rise excessively.
Suffocation from leakage of R410A is almost non-existent.
With the recent increase in the number of high concentration
buildings, however, the installation of multi air conditioner
systems is on the increase because of the need for effective
use of fl oor space, individual control, energy conservation by
curtailing heat and carrying power etc.
Most importantly, the multi air conditioner system is able to
replenish a large amount of refrigerant compared with
conventional individual air conditioners. If a single unit of the
multi conditioner system is to be installed in a small room,
select a suitable model and installation procedure so that if
the refrigerant accidentally leaks out, its concentration does
not reach the limit (and in the event of an emergency,
measures can be made before injury can occur).
In a room where the concentration may exceed the limit,
create an opening with adjacent rooms, or install mechanical
ventilation combined with a gas leak detection device.
The concentration is as given below.
Total amount of refrigerant (lbs (kg))
Min. volume of the indoor unit installed room (ft
≤ Concentration limit (lbs/ft (kg/m ))
3 3
Concentration limit
Compliance to the local applicable regulations and standards
for the concentration limit is required.
NOTE 1 :
If there are 2 or more refrigerating systems in a single
refrigerating device, the amounts of refrigerant should be as
charged in each independent device.
Outdoor unit
e.g.,
e.g.,
charged amount
charged amount
((22lbs) 10kg)
(33lbs (15kg))
Room A Room B Room C Room D Room E Room F
Indoor unit
For the amount of charge in this example:
The possible amount of leaked refrigerant gas in rooms A,
B and C is 22lbs (10kg).
The possible amount of leaked refrigerant gas in rooms
D, E and F is 33lbs (15kg).
Important
NOTE 2 :
The standards for minimum room volume are as
follows.
(1) No partition (shaded portion)
(2) When there is an effective opening with the adjacent
room for ventilation of leaking refrigerant gas (opening
without a door, or an opening 0.15% or larger than the
respective fl oor spaces at the top or bottom of the door).

Refrigerant piping
Indoor unit
(3) If an indoor unit is installed in each partitioned room and
the refrigerant piping is interconnected, the smallest
room of course becomes the object. But when a
mechanical ventilation is installed interlocked with a gas
leakage detector in the smallest room where the density
limit is exceeded, the volume of the next smallest room
3 (m 3 )) becomes the object.
