Safety caution
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 floor 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.
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.
For the amount of charge in this example:
The possible amount of leaked refrigerant gas in
rooms A, B and C is 22 lbs (10 kg).
The possible amount of leaked refrigerant gas in
rooms D, E and F is 33 lbs (15 kg).
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 floor 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.

2-1. Selection flow chart
(1) Determination of indoor air-conditioning load at each room.
(2) Preliminary selection of indoor units in the standard capacity no less
than air-conditioning load at each room.
(3) Calculate corrected capacity A of each indoor unit by correcting of
indoor temperature for the standard capacity of each indoor unit.
([Chart 1])
(4) Preliminary selection of outdoor unit in the standard capacity no less
than total values of corrected capacity A in indoor units. At the same time,
check both connectable indoor units number and the outdoor unit
diversity(Connected ratio of indoor units to outdoor units) for the
specifications.
(5) Calculate corrected capacity B of each indoor unit by following 2 steps.
Step1:Find the correction value of "Connecting pipe length and lift" by
both the longest length and the largest height with selected piping
condition at (4) or (4)'. ([Chart 3])
Step2:Calculate capacity B by multiplying the value of step1 by corrected
capacity A.
(6) Corrected capacity B of indoor
unit >= air-conditioning load (for All
rooms)
(9) Corrected capacity C of indoor
unit >= air-conditioning load (for All
rooms)
(7) Find correction values of below items for the standard capacity of
outdoor unit selected at (4) or (4)'.
Then determination of total corrected capacity of the selected outdoor unit
by all multiplying.
-Correction of indoor temperature condition ([Chart 1])
-Correction of outdoor temperature condition ([Chart 2])
-Correction of connecting pipe length and lift between indoor and outdoor
units by both the longest length and the largest height ([Chart 3])
-Correction of outdoor unit diversity in only over 100 % ([Chart 4])
-Correction of frost condition on outdoor heat exchanger when in heating
([Chart 5])
(8) Calculate corrected capacity C of each indoor unit by multiplying the
total corrected capacity of outdoor unit at (7) by proportional division of
each indoor unit standard capacity for total standard capacity of all indoor
units.

2-2. Combination conditions for indoor unit and
outdoor unit
2-2-1. The capacity code for indoor unit, the capacity code is decided for each capacity rank.
2-2-2. The capacity codes of outdoor units are decided at each capacity type. The maximum number of connectable
indoor units and the total value of capacity codes of the indoor units are also decided.
NOTE
Compared with the capacity code of the outdoor unit, the total value of capacity codes of the connectable indoor
units differs based on the height difference between the indoor units.
When the height difference between the indoor units is 49 ft (15 m) or less
If “Medium Static Ducted Type (MMD-AP***BH)” is excluded in the system: Total indoor capacity code must be
between 80% and 125% of the capacity of the outdoor unit.
Total indoor capacity code must be between 80% and 120% of the capacity of the outdoor unit.
If “one of 007, 009 or 012 of 4-way Air Discharge Cassette type (MMU-AP***H*)” is included in the system:
Total indoor capacity code must be 80% - 105%.
When the height difference between the indoor units is over 49 ft (15 m)
Total indoor unit capacity code (Equivalent to Capacity) must be between 80% and 105% of the capacity of the
outdoor unit.
If “one of 007, 009 or 012 of 4-way Air Discharge Cassette type (MMU-AP***H*)” is included in the system:
Total indoor capacity code must be 80% - 105%.
