Indoor Unit Installation
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.
• 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.
ENGLISH
NOTE
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.
CAUTION
• 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.
• If the length of suspension bolt is more than 1.5 m(4.92 ft), it is
required to prevent vibration.
• 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.
CAUTION
• 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

Performing leak test & insulation
Leak test
LEAK TEST WITH NITROGEN (before opening valves)
In order to detect basic refrigerant leaks, before recreating the vacuum
and recirculating the R-410A, it’s responsibility of installer to pressurize the
whole system with nitrogen (using a pressure regulator) at a pressure above
4.1 MPa(594.7 psig) (gauge).
Leak check
LEAK TEST WITH R-410A (after opening valves)
Before opening valves, discharge all the nitrogen into the system and create
vacuum. After opening valves check leaks using a leak detector for refrigerant
R-410A.
CAUTION
• Discharge all the nitrogen to create a vacuum and charge the system.
Insulation
Once you have checked that there are no leaks in the system, you can insulate the piping and hose.
1. To avoid condensation problems, place T13.0 (1/2") or thicker Acrylonitrile
Butadien Rubber separately around each refrigerant pipe.
NOTE
• Always make the seam of pipes face upwards.
2. Wind insulating tape around the pipes and drain hose avoiding to compress
the insulation too much.
3. Finish wrapping insulating tape around the rest of the pipes leading to the
outdoor unit.
4. The pipes and electrical cables connecting the indoor unit with the outdoor
unit must be fixed to the wall with suitable ducts.
CAUTION

Wiring work
CAUTION
• Select the power cable in accordance with relevant local and national regulations.
• Wire size must comply with local and national code.
• For the power cable, use the grade of H07RN-F or H05RN-F materials.
• You should connect the power cable into the power cable terminal and fasten it with a clamp.
• The unbalanced power must be maintained within 10 % of supply rating among whole indoor units.
• 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.
• 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.
• Connect the power cable to the auxiliary circuit breaker. An all pole disconnection from the power supply must
be incorporated in the fixed wiring(≥3 mm(1/8")).
• You must keep the cable in a protection tube.
• Keep distances of 50 mm(2") or more between power cable and communication cable.
• Maximum length of power cables are decided within 10 % of power drop. If it exceeds, you must consider
another power supplying method.
• The circuit breaker(ELCB or MCCB+ELB) should be considered more capacity if many indoor units are connected
from one breaker.
• Use round pressure terminal for connections to the power terminal block.
• For wiring, use the designated power cable and connect it firmly, then secure to prevent outside pressure being
exerted on the terminal board.
• Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will strip the
head and make proper tightening impossible.
• Over-tightening the terminal screws may break them.
• See the table below for tightening torque for the terminal screws.

Advanced function: Controlling cooling/heating current or power saving with motion detect.
Minimizing fan operation when thermostat is off
- Fan operates for 20 seconds at an interval of 5 minutes in heat mode.
(*2)
1: Fan is turned on continually when the hot water heater is turned on,
3: Fan is turned off when the hot water heater is turned on with cooling only indoor unit
Cooling only indoor unit: To use this option, install the Mode Select switch (MCM-C200) on the outdoor unit and fix it as
cool mode.
(*3)
When the following 2 or 3 is used as external heater On/Off signal, the signal for monitoring external contact control will
not be output.
2: Fan is turned on continually when the external heater is turned on,
3: Fan is turned off when the external heater is turned on with cooling only indoor unit
Cooling only indoor unit: To use this option, install the Mode Select switch (MCM-C200) on the outdoor unit and fix it as
cool mode.
❋❋ If Fan is set to off for cooling only indoor unit by setting the SEG9=3 or SEG15=3, you need to use an external sensor or
wired remote controller sensor to detect indoor temperature exactly.
(*4)
Default setting value
- 4Way Cassette, Mini 4Way Cassette: 5 °C (9 °F)
- Other indoor units: 2 °C (3.6 °F)
(*5)
This function can be applied to 4 Way Cassette and Mini 4 Way Cassette only. If the air conditioner operates the heating
mode immediately after finishing the cooling mode, the condensated water in the drain pan becomes water vapor by the
heat of the indoor unit heat exchanger. Since the water vapor might be condensed on the indoor unit, which may fall into
a living space, use this function to get rid of the water vapor out of the indoor unit by operating the fan (for maximum 20
minutes) even when the indoor unit is turned off after cooling mode is turned to heating mode .

the lowest place.
For example, When the indoor unit is installed 40 m(131.23 ft) higher than the indoor unit installed at
the lowest place, select the option "1".
(*2)
Distance : The difference 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".
(100 m(328 ft) - 40 m(131.23 ft) = 60 m(196.85 ft))

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 off when the heating thermostat is off.
(*1)
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 4.5 °C(8.1 °F) for 10 minutes.
Room temp. > set temp. + f(heating compensation temp.)
- External heater is turned off when the temperature is maintained as 4.5 °C(8.1 °F) + 1 °C(1.8 °F) [1 °C(1.8 °F) is
