Before installing the unit, make sure you read all the “Safety precau-
tions”.
Please report to your supply authority or obtain their consent before
connecting this equipment to the power supply system.
Warning:
Describes precautions that must be observed to prevent danger of injury or
death to the user.
Caution:
Describes precautions that must be observed to prevent damage to the unit.
After installation work has been completed, explain the “Safety Precautions,” use,
and maintenance of the unit to the customer according to the information in the
Operation Manual and perform the test run to ensure normal operation. Both the
Installation Manual and Operation Manual must be given to the user for keeping.
These manuals must be passed on to subsequent users.
:Indicates a part which must be grounded.
Warning:
Carefully read the labels affixed to the main unit.
Warning:
• Ask a dealer or an authorized technician to install the unit.
• For installation work, follow the instructions in the Installation Manual and
use tools and pipe components specifically made for use with refrigerant
specified 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.
•
The unit must be securely installed on a structure that can sustain its weight.
• If the air conditioner is installed in a small 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.
• Ventilate the room if refrigerant leaks during operation. If refrigerant comes
into contact with a flame, poisonous gases will be released.
• All electric work must be performed by a qualified technician according to
local regulations and the instructions given in this manual.
• Use only specified 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 fire.
1.1. Before installation (Environment)
Caution:
• D
o not use the unit in an unusual environment. If the air conditioner is in-
stalled in areas exposed to steam, volatile oil (including machine oil), or sulfu-
ric gas, areas exposed to high salt content such as the seaside, the perform-
ance can be significantly reduced and the internal parts can be damaged.
• Do not install the unit where combustible gases may leak, be produced,
flow, or accumulate. If combustible gas accumulates around the unit, fire or
explosion may result.
• Do not keep food, plants, caged pets, artwork, or precision instruments in
the direct airflow 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 office, be pre-
pared 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 con-
ditioner 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 fins 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 condensation.
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 sufficient capacity. Otherwise,
a short circuit, overheating, or fire 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 opera-
tion. 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 protec-
tive parts are correctly installed. Rotating, hot, or high voltage parts can
cause injuries.
• Do not operate the air conditioner without the air filter set in place. If the air
filter 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 five minutes before turn-
ing off the main power switch. Otherwise, water leakage or breakdown may
result.
Note:
The phrase “Wired remote controller“ in this installation manual refers only to the PAR-31MAA.
If you need any information for the other remote controller, please refer to either the installation manual or initial setting manual which are included in these
boxes.
• The appliance shall be installed in accordance with national wiring regulations.
• The terminal block cover panel of the unit must be firmly attached.
• If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified 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.
• The user should never attempt to repair the unit or transfer it to another lo-
cation.
• After installation has been completed, check for refrigerant leaks. If refrig-
erant leaks into the room and comes into contact with the flame of a heater
or portable cooking range, poisonous gases will be released.
• When installing or relocating, or servicing the air conditioner, use only the
specified refrigerant (R410A) 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 specified 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.
• Place thermal insulation on the pipes to prevent condensation. If the drain-
pipe is installed incorrectly, water leakage and damage to the ceiling, floor,
furniture, or other possessions may result.
• Do not clean the air conditioner unit with water. Electric shock may result.
• Tighten all flare nuts to specification using a torque wrench. If tightened too
much, the flare nut can break after an extended period.
• Use circuit breakers (ground fault interrupter, isolating switch (+B fuse),
and molded case circuit breaker) with the specified capacity. If the circuit
breaker capacity is larger than the specified capacity, breakdown or fire
may result.

4.1. Precautions
For devices that use R410A refrigerant
• Use ester oil, ether oil or alkylbenzene oil (small amount) as the refrigera-
tion oil applied to the flared sections.
• Use C1220 copper phosphorus for copper and copper alloy seamless
pipes, to connect the refrigerant pipes. Use refrigerant pipes with the thick-
nesses specified in the table below. Make sure the insides of the pipes are
clean and do not contain any harmful contaminants such as sulfuric com-
pounds, oxidants, debris, or dust.
Warning:
When installing or relocating, or servicing the air conditioner, use only the
specified refrigerant (R410A) 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 haz-
ards.
The use of any refrigerant other than that specified 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
7.1. 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 sup-
ply 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 .
Do not carry out this test on the control wiring (low voltage circuit) termi-
nals.
Warning:
Do not use the air conditioner if the insulation resistance is less than 1 M .
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 finishes, 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 dis-
played.
After “startup” is displayed, green (once) and red
(once) blink alternately. <F1> • Incorrect connection of outdoor terminal block (R, S, T 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”.
1Select “Test run” from the Service menu, and press the [SELECT] button. (Fig. 7-1)
2Select “Test run” from the Test run menu, and press the [SELECT] button. (Fig. 7-2)

Press the [RETURN] button to return to the Test run operation screen.
Step 4 Confirm 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 insufficient. Therefore, the outdoor wind may cause the fan to stop rotating or to rotate in the opposite direction, but
this is not a problem.
