3 Maximum number of AC Cell is limited up to 96.
In case the number of connected indoor units are more than 96, some AC Cells should hold 2 or more indoor units.
4 In case of other Central control like SC-SLxN-E is connected in the same network, the connectable indoor unit is limited up to 64(32x2).
5 In case of previous superlink protocol, the superlink mode of new central control should be set "Previous".
6 In case of (YES[A] or YES[B]), previous central control is available to use. But the limitation of connectable indoor unit and so on is
complied with the rule of previous superlink.

Corrosion protection treatment complies with regulation of The Japan Refrigeration and Air Conditioning Industry Association
Caution
Even if the outdoor unit is protected with the anti-salt damage treatment, it cannot be perfectly free from rusting.
The following points should be kept in mind during installation and maintenance of the outdoor units.
Installation
(1) When installing the outdoor unit close to the coastal area, provide a windbreak to protect it from direct sea breeze and
salt water splash.
(2) Select a well-drained place to install.
(3) If any scratch or damages occurred on the outdoor unit during installation, repair it carefully.
Maintenance
(1) Clean salt grains on the outdoor unit with fresh water periodically.
(2) Apply rust preventive at regular intervals for maintenance depending on the conditions at the installation place
(consulting with the withstanding capacity).
(3) Confirm reset of screw tap after maintenance, if missing it may cause corrosion occurred from the hole of screw tap.
(4) During prolonged non operation periods, protect the unit with covering.

“CAUTION” Cooling operation under low outdoor air temperature conditions
KXZ models can be operated in cooling mode at low outdoor air temperature condition within above temperature range. However in
case of severely low temperature conditions if the following precaution is not observed, it may not be operated in spite of operable
temperature range mentioned above and cooling capacity may not be established under certain conditions.
[Precaution]
In case of severely low temperature condition
1) Install the outdoor unit at the place where strong wind cannot blow directly into the outdoor unit.
2) If there is no installation place where can prevent strong wind from directly blowing into the outdoor unit, prepare a windbreak
fence or something like that locally in order to divert the strong wind from the outdoor unit.
[Reason]
Under the low outdoor air temperature conditions of -5˚C or lower, if strong wind directly blow into the outdoor unit, the outdoor
heat exchanger temperature will drop, even though the outdoor fan is stopped by outdoor fan control. This makes high and low pressures to drop as well. This low pressure drop makes the indoor heat exchanger temperature to drop and will activate anti-frost control
at indoor heat exchanger at frequent intervals, that cooling operation may not be established for any given time.

Specification for installation with large head difference (Applicable to: FDC280 - 1680KXZE1)
In case when the outdoor unit is installed at a higher place and the difference in the elevation between the indoor and the outdoor
units is larger than 50 m and smaller than 70 m, the limitation on application differs partially from ordinary applications and, instead,
the following specification applies. The pipe size, refrigerant amount and way of switch setting become also different.
In the range of use, the outdoor air temperature (lower limit), indoor units allowed to combine, total piping length and difference in
the elevation between indoor units in the same system are different from ordinary applications.

(4) Microcomputer control
Setting of microcomputer control needs to be changed when the outdoor unit is installed upwards and the difference in elevation is larger
than 50 m and less than 70 m. Make sure to set SW6-4 at ON position on both the master and slave units, before turning the power on.
When the difference between the longest and shortest piping is longer
than 40 m, adjust the difference in the elevation of indoor units in a
system such that it will fall in the OK range on the following graph.
When the difference in the elevation between the indoor and the outdoor
units is 50 m – 70 m, the difference between the longest and shortest
piping cannot exceed 40 m. Reduce it to less than 40 m.
If the refrigerant quantity over occurs when the difference between the
ongest and shortest piping is longer than 40 m, there is a risk that the
heating capacity becomes insufficient. Take sufficient care to adjust
the additional refrigerant quantity at correct value.

(a) Calculating the indoor unit capacity compensation
Indoor unit capacity (cooling, heating) = Indoor unit total rated capacity
× Capacity compensation coefficient according to temperature conditions
See item (3) (a) concerning the capacity compensation coefficient according to temperature conditions.
(b) Calculating the outdoor unit capacity compensation
Outdoor Unit Capacity (Cooling, Heating) = Outdoor unit rated capacity (rated capacity when 100% connected)
× Capacity compensation coefficient according to temperature conditions
× Capacity compensation coefficient according to piping length
× Capacity compensation coefficient according to height difference
× Correction of heating capacity in relation to the frost on the outdoor unit

× Capacity compensation coefficient according to indoor unit connection
capacity
See item (3) (a) concerning the capacity compensation coefficient according to temperature conditions.
See item (3) (b) concerning the capacity compensation coefficient according to piping length.
See item (3) (c) concerning the capacity compensation coefficient according to height difference. This compensation
should be carried out only in cases where the outdoor unit is lower during cooling and higher during heating.
See item (3) (d) correction of heating capacity in relation to the frost on the outdoor unit heat exchanger. This compensation should be carried out only when calculating the heating capacity.
See item (3) (e) concerning the capacity compensation coefficient according to indoor unit connected capacity. This
compensation should be carried out only in cases where the indoor unit total capacity is 100% or higher.
(c) Calculating system capacity
Compare the capacities determined in items (a) and (b) above and let the smaller value be the system capacity (cooling,
heating).
In cases where indoor unit total capacity (cooling, heating) > outdoor unit capacity (cooling, heating)
System capacity (cooling, heating) = Outdoor unit capacity (cooling, heating)
In cases where indoor unit total capacity (cooling, heating) < outdoor unit capacity (cooling, heating)
System capacity (cooling, heating) = Indoor unit capacity (cooling, heating)
(d) Calculating indoor unit capacity [item (c) 1 only]
Indoor unit capacity (cooling, heating) = System capacity (cooling, heating)
× [(Indoor unit capacity) / (Indoor unit total capacity)]

6.WARNINGS
Check of concentration limit
Important
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 nonexistent. 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 dose 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.
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).
Outdoor unit
Refrigerant piping
Indoor unit
③ If an indoor unit is installed in each partitioned room and
the refrigerant tubing is interconnected, the smallest
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.

The concentration limit of R410A which is used in multi air
conditioners is 0.42kg/m3. (ISO5149)
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.
