Cleaning and Maintenance
Problem Solution
The air is not cool or
warm enough.
• Close the windows and doors to maximize the cooling and heating
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.
Unpleasant odours
permeate the room.
• If the air conditioner is running in a smoky area or if there is a smell
entering from outside, ventilate the room properly.
• If both indoor temperature and indoor humidity are high, operate the air
conditioner in the Clean or Fan mode for 1 to 2 hours.
• If the air conditioner has not been operated for an extended period of
time, clean the indoor unit and then operate the air conditioner in the
Fan mode for 3 to 4 hours to dry the inside of the indoor unit for removal
of unpleasant odours.
• If the air filter blocked with dirt, clean the air filter.
Steam is produced
on the indoor unit.
• In winter, if the indoor humidity is high, steam may be produced around
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.
• When 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.

Installation Procedure
Step 1 Installing the indoor unit
When deciding on the location of the air conditioner the
following restrictions must be taken into account.
1 Place the pattern sheet on the ceiling at the spot
where you want to install the indoor unit.
NOTE
• 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, be sure
to maintain the correct dimensions between the
markings.
2 Insert bolt anchors, use existing ceiling supports or
construct a suitable support as shown in figure.
Concrete
Hole in anchor
Hole in plug
Suspension bolt (ø9.52 or M10)
Insert
3 Install the suspension bolts, depending on the ceiling
type.
Ceiling support
CAUTION
• Make sure 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 the suspension bolt is more than 1.5 m,
you are 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 and washers to the suspension bolts,
making space for hanging the indoor unit.
CAUTION
• You must install all of the suspension rods.
• It is important to leave sufficient space in the false
ceiling to allow access for maintenance or repairs to
the drainage pipe connection, the refrigerant pipe
connection, or to remove the unit if necessary.
5 Hang the indoor unit to the suspension bolts between
two nuts. Screw the nuts to suspend the unit.

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 4.1 MPa in order to immediately detect
leaks on the refrigerant fittings.
Made vacuum for 15 minutes and pressurizing system
with nitrogen.

Step 3 Insulating the refrigerant pipes
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 Acrylonitrile
Butadien Rubber separately around each refrigerant
pipe.
No gap
NBR (T13.0 or thicker)
NOTE
• Always make the seam of pipes face upwards.
2 Wind insulating tape around the pipes and drain hose
avoiding compressing 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.

High humidity locations such as shorelines, hot springs,
lake 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
EEV kit and MCU
‐ You can contact the gas side and liquid side pipes
but the pipes should not be pressed.
‐ When contacting the gas side and liquid side pipe,
use 1 grade thicker insulator.

Step 4 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:

Installation Procedure
* Advanced function: Controlling cooling/heating current or power saving with motion detect.
(*1) When Cooling or dry mode is off. The indoor fan operate in setting minutes.
(*2) Minimizing fan operation when thermostat is off
- Fan operates for 20 seconds at an interval of 5 minutes in heat mode.
- Fan stops or operates Ultra low in Cooling when thermostat is off.
(*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.
If the "Cooling Priority" option is set in the Heat Pump outdoor unit, the indoor unit can operate in the Heat mode
owing to the water heater even if the outdoor unit is running in the Cool mode.
(*4) When Normal Signal Control is enabled, the external control is turned on by the short-circuit signal and off by the
open-circuit signal.
When Reverse Signal Control is enabled, the external control is turned off by the short-circuit signal and on by the
open-circuit signal.
(*5) 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.
- If the "Cooling Priority" option is set in the Heat Pump outdoor unit, the indoor unit can operate in the Heat mode
owing to the external heater even if the outdoor unit is running in the Cool mode.
(*6) When indoor unit is in cooling or Dry mode, The output signal is “ON”
(*7) For free cooling control, Economizer controller is required.
(*8) 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) Duration for Auto Change Over triggered when you set dual set points in the Auto mode using the wired remote
control MWR-WG00*N.
During the automatic heating operation, if the specified time has elapsed in the state of "the room temperature >
the cooling temperature in the Auto mode + the primary cooling temperature (set in the Auto Change Over screen
after entering the User mode by pressing the
button on the wired remote control)" the air conditioner changes
into the automatic cooling operation.
During the automatic cooling operation, if the specified time has elapsed in the state of "the room temperature <
the heating temperature in the Auto mode - the primary heating temperature (set in the Auto Change Over screen
after entering the User mode by pressing the
button on the wired remote control)" the air conditioner changes
into the automatic heating mode.
(*2) 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”.
(*3) 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 and the corresponding indoor unit is 40 m away from an
outdoor unit, select the option “2”. (100 - 40 = 60m)
(*4) For MTFC option, MTFC(Multi Tenant Function Controller) kit is required.
(*5) 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.
Example2)Setting02seriesSEG15=”2”/Setting05seriesSEG18=”A”:Roomtemp.≤settemp.+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.)

• If your indoor units support both cooling and heating, the mixed operation (two or more indoor units operate in
different modes simultaneously) is not available when the indoor units are connected to the same outdoor unit. If
you set an indoor unit as the master indoor unit by using the remote control, the outdoor unit automatically operate
in the current mode of the master indoor unit.
Emergency Temperature Output (ETO) function
CAUTION
• In order to deploy the ETO function, the MIM-B14, an external contact interface module, must be installed in each
indoor unit.
‐ The ETO is a concept of emergency operation of indoor units. If the indoor unit 1 (main indoor unit) stops because
of an error, the indoor unit 2 (sub indoor unit) starts to operate.
‐ Basically, the indoor unit 2 operates in the previous mode. [For the first time operation, it starts in 24 °C Auto
mode.]
‐ To set more detailed operation conditions for the indoor unit 2, use the S-net Pro.
