efficiencies.
• If the Cool mode is stopped and then started immediately, cool air comes
out after about 3 minutes to protect the compressor of the outdoor unit.
• When the Heat mode is started, warm air does not come out
immediately to prevent cool air from coming out at the beginning.
• If the refrigerant pipe is too long, the cooling and heating efficiencies
may be decreased. Avoid exceeding the maximum pipe length.
The air conditioner
makes strange
noises.
• In certain conditions (especially, when the outdoor temperature is
lower than 20°C), a hissing, rumbling, or splashing sound may be heard
while the refrigerant is circulating through the air conditioner. This is a
normal operation.
• When you press the (Power) button on the remote control, noise
may be heard from the drain pump inside the air conditioner. This noise
is a normal sound.

the air outlet while the defrost function is running. This is a normal
operation.
The outdoor unit
fan continues to
operate when the
air conditioner is
turned off.
• W hen the air conditioner is turned off, the outdoor unit fan may
continue to operate to reduce noise of the refrigerant gas. This is a
normal operation.
Water drops
from the piping
connections of the
outdoor unit.
• Condensation may develop due to the difference in temperature. This is
a normal condition.
Steam is produced
on the outdoor unit.
• In winter, when the air conditioner runs in the Heat mode, the frost on
the heat exchanger melts and steam may be produced. This is a normal
operation, neither product malfunction nor a fire.

Step 2 Performing the gas leak test
To identify potential gas leaks on the indoor unit, inspect
the connection area of each refrigerant pipe using a leak
detector for R-410A.
Before recreating the vacuum and recirculating the
refrigerant gas, pressurize the whole system with nitrogen
(using a cylinder with a pressure reducer) at a pressure
above 0.2 MPa, less than 4 MPa (gauge) in order to
immediately detect leaks on the refrigerant fittings.
Made vacuum for 15 minutes and pressurizing system with
nitrogen.

or riversides, and ridges (when part of the building is covered
by earth and sand)
<Operation purpose condition>
Restaurant ceiling, sauna, swimming pool etc.
<Building construction condition>
Ceilings frequently exposed to moisture and cooling are
not covered. For example, pipes installed at a corridor of a
dormitory and studio or near an exit that opens and closes
frequently.
Places (where the pipes are installed) that are highly humid
due to a lack of ventilation.
• Refrigerant pipe before EEV kit and MCU or without

Step 5 Connecting the power and
communication cables
Power and communication cable connection
• Before wiring work, you must turn off all power source.
• Connect the power and communication cable among
the units within maximum length to set the voltage
drop under 10%.
• The auxiliary circuit breaker (ELCB, MCCB, ELB) should
be considered more capacity if many indoor units are
connected from one breaker.
• Connect F3, F4(for communication) to the
communication cable of the wired remote control.
• Tighten the electric wires with a proper tool within the
torque limit to connect and fix them firmly, and then
organize the wires to prevent outside pressure being
exerted on the covers and other parts. Failure to do so
may result in overheating, electric shock, and fire.
• To protect the product from water and possible shock,
you should keep the power and the communication
cables of the indoor and outdoor units in the iron pipe.
• Connect the power cable to the auxiliary circuit
breaker (ELCB, MCCB, ELB).
• Keep distances of 50mm or more between power cable
and communication cables.
• 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)
• Screws on terminal block must not be unscrewed with
the torque less than 12 kgf•cm.
• When installing the indoor unit in a computer room,
use the double shielded (tape aluminum / polyester
braid + copper) cable of FROHH2R type.

Installation Procedure
(*3) 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.
(*4) 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.
(*5) When indoor unit is in cooling or Dry mode, The output signal is “ON”
(*6) For free cooling control, Economizer controller is required.
(*7) 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 condensate
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

Installation Procedure
(*1) Height difference : The difference of the height between the corresponding indoor unit 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) The difference between the pipe length of the indoor unit installed 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 away from
an outdoor unit, select the option “2”. (100 - 40 = 60m)
(*3) For MTFC option, MTFC(Multi Tenant Function Controller) kit is required.
(*4) 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.
Example 1) Setting 02 series SEG9 =”1” / Setting 05 series SEG18 = “0”: The 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.
Example 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.)
