It is recommended to install theY-joint before installing the
indoor unit.

1

Place the pattern sheet on the ceiling at the spot where
you want to install the indoor unit.

Note XSince the diagram is made of paper, it may

shrink or stretch slightly due to temperature
or humidity. For this reason, before drilling
the holes maintain the correct dimensions
between the markings.

X

Pattern sheet is supplied depending on the

model type.

2

Insert bolt anchors, use existing ceiling supports or
construct a suitable support as shown in figure.

3

Install the suspension bolts depending on the ceiling
type.
X

Ensure that the ceiling is strong enough to

support the weight of the indoor unit.
Before hanging the unit, test the strength of
each attached suspension bolt.

X



If the length of suspension bolt is more

than

4.92ft(1.5m)

, it is required to prevent vibra-

tion.

XIf this is not possible, create an opening on

the false ceiling in order to be able to use it
to perform the required operations on the
indoor unit.

4

Screw eight nuts to the suspension bolts making space
for hanging the indoor unit.

X

You must install the suspension bolts more

than four when installing the indoor unit.

5

Hang the indoor unit to the suspension bolts between
two nuts.

Note Piping must be laid and connected inside

the ceiling when suspending the unit. If the
ceiling is already constructed, lay the piping
into position for connection to the unit
before placing the unit inside the ceiling.

6

Screw the nuts to suspend the unit.

7

Adjust level of the unit by using measurement plate for
all 4 sides.

Note For proper drainage of condensate, give a

'A' slant to the left or right side of the unit
which will be connected with the drain hose,
as shown in the figure. Make a tilt when you
wish to install the drain pump, too.

On delivery, the indoor unit is loaded with inert gas.
All this gas must therefore be purged before connecting the
assembly piping. To purge the inert gas, proceed as follows.

Unscrew the pinch pipe at the end of each refrigerant pipe.

Result: All inert gas escapes from the indoor unit.

Note To prevent dirt or foreign objects from getting

into the pipes during installation, do NOT remove
the pinch pipe completely until you are ready to
connect the piping.

X Select the power cable in accordance with relevant local and national regulations.
X Wire size must comply with local and national code.

X For the power cable, use the grade of H07RN-F or H05RN-F materials.
X You should connect the power cable into the power cable terminal and fasten it with a clamp.
X The unbalanced power must be maintained within 10% of supply rating among whole indoor units.
X

If the power is unbalanced greatly, it may shorten the life of the condenser. If the unbalanced power is
exceeded over 10% of supply rating, the indoor unit is protected, stopped and the error mode indicates.

X To protect the product from water and possible shock, you should keep the power cable and the

connection cord of the indoor and outdoor units in the iron pipe.

X Connect the power cable to the auxiliary circuit breaker.

An all pole disconnection from the power supply must be incorporated in the fixed
wiring[≥1/8"(3mm)].

X You must keep the cable in a protection tube.
X Keep distances of 2"(50mm) or more between power cable and communication cable.

X Maximum length of power cables are decided within 10% of power drop. If it exceeds, you must

consider another power supplying method.

X The circuit breaker(ELCB or MCCB+ELB) should be considered more capacity if many indoor units

are connected from one breaker.

X Use round pressure terminal for connections to the power terminal block.
X For wiring, use the designated power cable and connect it firmly, then secure to prevent outside

pressure being exerted on the terminal board.

X Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head

will strip the head and make proper tightening impossible.

X Over-tightening the terminal screws may break them.
X See the table below for tightening torque for the terminal screws.

(*1) Height dierence : The dierence of the height between the corresponding indoor uint and the indoor unit installed at the lowest place.

For example, When the indoor unit is installed 131.2ft(40m) higher than the indoor unit installed at the lowest place, select
the option "1".

(*2)

Distance : The dierence between the pipe length of the indoor unit istalled at farthest place from an outdoor unit and the pipe length of the

corresponding indoor unit from an outdoor unit.

For example, when the farthest pipe length is 100m(328 ft) and the corresponding indoor unit is 40m(131.23ft) away from an
outdoor unit, select the option "2".
[328-131.2=196.8ft(100 - 40 = 60m)]

(*3) Heater operation when the SEG9 of 02 series installation option is set to using hot water heater or when SEG15 is set to using external heater

e.g. 1) Setting 02 series SEG9 =”1” / Setting 05 series SEG18 = “0”: Hot water heater is turned on at the same time as the heating

thermostat is on, and turned o when the heating thermostat is o.

e.g. 2) Setting 02 series SEG15 =”2” / Setting 05 series SEG18 =”A”:

Room temp. ≤ set temp. + f(heating compensation temp.)

- External heater is turned on when the temperature is maintained as 8.1 °F(4.5 °C) for 10 minutes.
Room temp. > set temp. + f(heating compensation temp.)

- External heater is turned o when the temperature is maintained as 8.1 °F(4.5 °C) + 1.8 °F(1 °C) (1 °C is the Hysteresis for On/O
