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 (kg)
Min. volume of the indoor unit installed room (m
3
)
≤ Concentration limit (kg/m 3 )
The concentration limit of R410A which is used in
multi air conditioners is 0.44 kg/m
3 .
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.
e.g., charged amount (15 kg)
Outdoor unit e.g., charged amount
(10 kg)
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 10 kg.
The possible amount of leaked refrigerant gas in
rooms D, E and F is 15 kg.

NOTE 2 :
The standards for minimum room volume are
as follows.
(1) No partition (shaded portion)
NOTE 3 :
The minimum indoor fl oor area compared with the
amount of refrigerant is roughly as follows: (When the
ceiling is 2.7 m high)
(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).
(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 becomes
the object.

CONFIRMATION OF INDOOR UNIT SETUP
Prior to delivery to the customer, check the address and setup of the indoor unit, which has been installed in this time
and fi ll the check sheet (Table below). Data of four units can be entered in this check sheet.
Copy this sheet according to the No. of the indoor units. If the installed system is a group control system, use this
sheet by entering each line system into each installation manual attached to the other indoor units.

Check indoor unit address. (For check method, refer to Applicable controls in this sheet.)
* In case of a single system, it is unnecessary to enter the indoor address. (CODE No.: Line [12], Indoor [13], Group [14], Central control [03] )
