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 R410A, it’s responsible of installer to pressurize the whole
system with nitrogen (using a pressure regulator) at a pressure above
4.1MPa (gauge).
LEAK TEST WITH R410A (after opening valves)
Leak check
Before opening valves, discharge all the nitrogen into the system and
create vacuum. After opening valves check leaks using a leak detector for
refrigerant R410A.
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 or thicker Acrylonitrile
Butadien Rubber separately around each refrigerant pipe.
NOTE
No gap
• Always make the seam of pipes face upwards.
NBR(T13.0 or thicker)
2. Wind insulating tape around the pipes and drain hose avoiding to
compress the insulation too much.
Insulation cover pipe

Wiring Work
CAUTION
• Select the power cable in accordance with relevant local and national regulations.
• Wire size must comply with local and national code.
• Power Supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene
sheathed flexible cord. (Code designation IEC:60245 IEC 57 / CENELEC: H05RN-F or
IEC:60245 IEC 66 / CENELEC: H07RN-F)
• 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).
• 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 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.

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
- Other indoor units: 2 °C
(*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 .

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.)
