• 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(≥3mm).

Safety Precautions
• You must keep the cable in a protection tube.
• Keep distances of 50mm 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 out-side
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.
Installation Procedure
• See the table below for tightening torque for the
terminal screws.

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 control sensor to detect indoor temperature exactly.
Installation Procedure
(*5) Default setting value
–– 4Way Cassette, Mini 4Way Cassette: 5 °C
–– Other indoor units: 2 °C
(*6) 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.

(*1) Height difference : T
he difference 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 40m 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 and the corresponding indoor unit is 40 m away from an outdoor unit, select the
option "2". (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 off when the heating thermostat is off.
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 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 + 1 °C (1 °C is the Hysteresis for
On/Off selection.)
