WARNING
(Risk of re)
This mark is for R32 refrigerant only. Refrigerant type is written on nameplate of outdoor unit.
In case that refrigerant type is R32, this unit uses a ammable refrigerant.
If refrigerant leaks and comes in contact with re or heating part, it will create harmful gas and there is risk of re.
Read the OPERATION MANUAL carefully before operation.
Service personnel are required to carefully read the OPERATION MANUAL and INSTALLATION MANUAL before operation.
Further information is available in the OPERATION MANUAL, INSTALLATION MANUAL, and the like.
Warning:
• Carefully read the labels afxed to the main unit.
• Ask a dealer or an authorized technician to install, relocate and repair the
unit.
• The user should never attempt to repair the unit or transfer it to another loca-
tion.
• For installation and relocation work, follow the instructions in the Installation
Manual and use tools and pipe components specically made for use with
refrigerant specied in the outdoor unit installation manual.
• The unit must be installed according to the instructions in order to mini-
mize the risk of damage from earthquakes, typhoons, or strong winds. An
incorrectly installed unit may fall down and cause damage or injuries.
• Do not alter the unit. It may cause re, electric shock, injury or water leak-
age.
• The unit must be securely installed on a structure that can sustain its
weight.
• The appliance shall be stored in a well-ventilated area where the room size
corresponds to the room area as specied for operation.
• If the air conditioner is installed in a small room or closed room, measures
must be taken to prevent the refrigerant concentration in the room from
exceeding the safety limit in the event of refrigerant leakage. Should the
refrigerant leak and cause the concentration limit to be exceeded, hazards
due to lack of oxygen in the room may result.
• Keep gas-burning appliances, electric heaters, and other re sources (igni-
tion sources) away from the location where installation, repair, and other air
conditioner work will be performed.
If refrigerant comes into contact with a ame, poisonous gases will be
released.
• Ventilate the room if refrigerant leaks during operation. If refrigerant comes
into contact with a ame, poisonous gases will be released.
• All electric work must be performed by a qualied technician according to
local regulations and the instructions given in this manual.
• Do not use intermediate connection of the electric wires.
• Use only specied cables for wiring. The wiring connections must be made
securely with no tension applied on the terminal connections. Also, never
splice the cables for wiring (unless otherwise indicated in this document).
Failure to observe these instructions may result in overheating or a re.
• When installing or relocating, or servicing the air conditioner, use only the
specied refrigerant written on outdoor unit to charge the refrigerant lines.
Do not mix it with any other refrigerant and do not allow air to remain in the
lines.
If air is mixed with the refrigerant, then it can be the cause of abnormal high
pressure in the refrigerant line, and may result in an explosion and other
hazards.
The use of any refrigerant other than that specied for the system will
cause mechanical failure or system malfunction or unit breakdown. In the
worst case, this could lead to a serious impediment to securing product
safety.
• The appliance shall be installed in accordance with national wiring regula-
tions.
• This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction con-
cerning use of the appliance by a person responsible for their safety.
• Children should be supervised to ensure that they do not play with the ap-
pliance.
• The terminal block cover panel of the unit must be rmly attached.
• If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualied persons in order to avoid a hazard.
• Use only accessories authorized by Mitsubishi Electric and ask a dealer or
an authorized technician to install them.
• After installation has been completed, check for refrigerant leaks. If refrig-
erant leaks into the room and comes into contact with the ame of a heater
or portable cooking range, poisonous gases will be released.
• Do not use means to accelerate the defrosting process or to clean, other
than those recommended by the manufacturer.
• The appliance shall be stored in a room without continuously operating
ignition sources (for example: open ames, an operating gas appliance or
an operating electric heater).
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
• Pipe-work shall be protected from physical damage.
• The installation of pipe-work shall be kept to a minimum.
• Compliance with national gas regulations shall be observed.
• Keep any required ventilation openings clear of obstruction.
• Do not use low temperature solder alloy in case of brazing the refrigerant
pipes.
• When performing brazing work, be sure to ventilate the room sufciently.
Make sure that there are no hazardous or ammable materials nearby.
When performing the work in a closed room, small room, or similar loca-
tion, make sure that there are no refrigerant leaks before performing the
work.
If refrigerant leaks and accumulates, it may ignite or poisonous gases may
be released.

1.1. Before installation (Environment)
Caution:
• Do not use the unit in an unusual environment. If the air conditioner is installed
in areas exposed to steam, volatile oil (including machine oil), or sulfuric gas,
areas exposed to high salt content such as the seaside, the performance can
be signicantly reduced and the internal parts can be damaged.
• Do not install the unit where combustible gases may leak, be produced, ow,
or accumulate. If combustible gas accumulates around the unit, re or explo-
sion may result.
• Do not keep food, plants, caged pets, artwork, or precision instruments in the
direct airow of the indoor unit or too close to the unit, as these items can be
damaged by temperature changes or dripping water.
• When the room humidity exceeds 80% or when the drainpipe is clogged,
water may drip from the indoor unit. Do not install the indoor unit where such
dripping can cause damage.
• When installing the unit in a hospital or communications ofce, be prepared for
noise and electronic interference. Inverters, home appliances, high-frequency
medical equipment, and radio communications equipment can cause the air
conditioner to malfunction or breakdown. The air conditioner may also affect
medical equipment, disturbing medical care, and communications equipment,
harming the screen display quality.
1.2. Before installation or relocation
Caution:
• Be extremely careful when transporting the units. Two or more persons
are needed to handle the unit, as it weighs 20 kg or more. Do not grasp the
packaging bands. Wear protective gloves as you can injure your hands on
the ns or other parts.
• Be sure to safely dispose of the packaging materials. Packaging materials,
such as nails and other metal or wooden parts may cause stabs or other
injuries.
• Thermal insulation of the refrigerant pipe is necessary to prevent condensa-
tion. If the refrigerant pipe is not properly insulated, condensation will be
formed.
1.3. Before electric work
Caution:
• Be sure to install circuit breakers. If not installed, electric shock may result.
• For the power lines, use standard cables of sufcient capacity. Otherwise, a
short circuit, overheating, or re may result.
• When installing the power lines, do not apply tension to the cables.
• Be sure to ground the unit. If the unit is not properly grounded, electric shock
may result.
1.4. Before starting the test run
Caution:
• Turn on the main power switch more than 12 hours before starting operation.
Starting operation just after turning on the power switch can severely damage
the internal parts.
• Before starting operation, check that all panels, guards and other protective
parts are correctly installed. Rotating, hot, or high voltage parts can cause
injuries.
• Do not operate the air conditioner without the air lter set in place. If the air
lter is not installed, dust may accumulate and breakdown may result.
• Do not touch any switch with wet hands. Electric shock may result.
• Do not touch the refrigerant pipes with bare hands during operation.
• After stopping operation, be sure to wait at least ve minutes before turning
off the main power switch. Otherwise, water leakage or breakdown may result.
• Place thermal insulation on the pipes to prevent condensation. If the drain-
pipe is installed incorrectly, water leakage and damage to the ceiling, oor,
furniture, or other possessions may result.
• Do not clean the air conditioner unit with water. Electric shock may result.
• Tighten all are nuts to specication using a torque wrench. If tightened too
much, the are nut can break after an extended period.
• Use circuit breakers (ground fault interrupter, isolating switch (+B fuse), and
molded case circuit breaker) with the specied capacity. If the circuit breaker
capacity is larger than the specied capacity, breakdown or re may result.

4.1. Precautions
For devices that use R32/R410A refrigerant
• Use ester oil, ether oil or alkylbenzene oil (small amount) as the refrigeration
oil applied to the ared sections.
• Use C1220 copper phosphorus for copper and copper alloy seamless pipes,
to connect the refrigerant pipes. Use refrigerant pipes with the thicknesses
specied in the table below. Make sure the insides of the pipes are clean
and do not contain any harmful contaminants such as sulfuric compounds,
oxidants, debris, or dust.
Warning:
When installing or relocating, or servicing the air conditioner, use only the
specied refrigerant written on outdoor unit to charge the refrigerant lines. Do
not mix it with any other refrigerant and do not allow air to remain in the lines.
If air is mixed with the refrigerant, then it can be the cause of abnormal high
pressure in the refrigerant line, and may result in an explosion and other hazards.
The use of any refrigerant other than that specied for the system will cause
mechanical failure or system malfunction or unit breakdown. In the worst case,
this could lead to a serious impediment to securing product safety.

7. Test run
7.2. Test run
7.2.1. Using wired remote controller.
■ Make sure to read operation manual before test run. (Especially items to secure safety)
Step 1 Turn on the power.
● Remote controller: The system will go into startup mode, and the remote controller power lamp (green) and “Please Wait” will blink. While the lamp and message are
blinking, the remote controller cannot be operated. Wait until “Please Wait” is not displayed before operating the remote controller. After the power is turned on, “Please
Wait” will be displayed for approximately 2 minutes.
● Indoor controller board: LED 1 will be lit up, LED 2 will be lit up (if the address is 0) or off (if the address is not 0), and LED 3 will blink.
● Outdoor controller board: LED 1 (green) and LED 2 (red) will be lit up. (After the startup mode of the system nishes, LED 2 will be turned off.) If the outdoor controller
board uses a digital display, [- ] and [ -] will be displayed alternately every second.
If the operations do not function correctly after the procedures in step 2 and thereafter are performed, the following causes should be considered and eliminated if they
are found.
(The symptoms below occur during the test run mode. “Startup” in the table means the LED display written above.)
Symptoms in test run mode
Cause
Remote Controller Display OUTDOOR BOARD LED Display
< > indicates digital display.
Remote controller displays “Please Wait”, and
cannot be operated.
After “startup” is displayed, only green lights up.
<00>
• After power is turned on, “Please Wait” is displayed for 2 minutes
during system startup. (Normal)
After power is turned on, “Please Wait” is
displayed for 3 minutes, then error code is
displayed.
After “startup” is displayed, green (once) and red
(once) blink alternately. <F1>
• Incorrect connection of outdoor terminal block (~/N: L, N and S1,
S2, S3) (3N~: L1, L2, L3, N and S1, S2, S3)
After “startup” is displayed, green (once) and red
(twice) blink alternately. <F3, F5, F9> • Outdoor unit’s protection devise connector is open.
No display appears even when remote control-
ler operation switch is turned on. (Operation
lamp does not light up.)
After “startup” is displayed, green (twice) and red
(once) blink alternately. <EA. Eb>
• Incorrect wiring between the indoor and outdoor unit (Polarity is
wrong for S1, S2, S3.)
• Remote controller transmission wire short.
After “startup” is displayed, only green lights up.
<00>
• There is no outdoor unit of address 0. (Address is other than 0.)
• Remote controller transmission wire open.
Display appears but soon disappears even
when remote controller is operated.
After “startup” is displayed, only green lights up.
<00>
• After canceling function selection, operation is not possible for about
30 seconds. (Normal)
Step 2 Switch the remote controller to “Test run”.

Step 3 Perform the test run and check the airow temperature and auto vane.
1 Press the [F1] button to change the operation mode. (Fig. 7-3)
Cooling mode: Check that cool air blows from the unit.
Heating mode: Check that warm air blows from the unit.
2 Press the [SELECT] button to display the Vane operation screen, and then press
the [F1] and [F2] buttons to check the auto vane. (Fig. 7-4)
Press the [RETURN] button to return to the Test run operation screen.
Step 4 Conrm the operation of the outdoor unit fan.
The speed of the outdoor unit fan is controlled in order to control the performance of the unit. Depending on the ambient air, the fan will rotate at a slow speed and will keep
rotating at that speed unless the performance is insufcient. Therefore, the outdoor wind may cause the fan to stop rotating or to rotate in the opposite direction, but this is
not a problem.
► Do not carry out this test on the control wiring (low voltage circuit) terminals.
Warning:
Do not use the air conditioner if the insulation resistance is less than 1 M .
7.1. Before test run
► After completing installation and the wiring and piping of the indoor and
outdoor units, check for refrigerant leakage, looseness in the power supply
or control wiring, wrong polarity, and no disconnection of one phase in the
supply.
► Use a 500-volt megohmmeter to check that the resistance between the power
supply terminals and ground is at least 1 M .
