1. Safety precautions
► Before installing the unit, make sure you read all the “Safety precautions”.
► 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.
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.
Caution:
Describes precautions that must be observed to prevent damage to the unit.
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 minimize 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.
• The terminal block cover panel of the unit must be firmly attached.
• 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
location.
• After installation has been completed, check for refrigerant leaks. If refrigerant 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.
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 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 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.. 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.
• Place thermal insulation on the pipes to prevent condensation. If the drainpipe 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.
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.
• 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.
1.4. Before starting the test run
Caution:
• Turn on the main power switch more than 1 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 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 turning off the main power switch. Otherwise, water leakage or breakdown may
result.

• The ceiling work differs according to the construction of the building. Building
constructors and interior decorators should be consulted for details.
(1) Extent of ceiling removal: The ceiling must be kept completely horizontal and
the ceiling foundation (framework: wooden slats and slat holders) must be reinforced in order to protect the ceiling from vibration.
(2) Cut and remove the ceiling foundation.
(3) Reinforce the ends of the ceiling foundation where it has been cut and add ceiling foundation for securing the ends of the ceiling board.
(4) When installing the indoor unit on a slanted ceiling, attach a pillar between the
ceiling and the grille and set so that the unit is installed horizontally.
1 Wooden structures
• Use tie beams (single storied houses) or second floor beams (2 story houses) as
reinforcing members.
• Wooden beams for suspending air conditioners must be sturdy and their sides
must be at least 6 cm long if the beams are separated by not more than 90 cm
and their sides must be at least 9 cm long if the beams are separated by as much
as 180 cm. The size of the suspension bolts should be ø10 (3/8"). (The bolts do
not come with the unit.)
2 Ferro-concrete structures

(with insulation), washers (without insulation) and nuts (double).
• Fit the washer with cushion so that the insulation faces downward.
• In case of using upper washers to suspend the main unit, the lower washers (with
insulation) and nuts (double) are to be set later.
2. Lift the unit to the proper height of the suspension bolts to insert the mounting
plate between washers and then fasten it securely.
3. When the main unit cannot be aligned against the mounting hole on the ceiling,
it is adjustable owing to a slot provided on the mounting plate.
• Make sure that A is performed within 17-22 mm. Damage could result by failing
to adhere to this range. (Fig. 3-7)
Caution:
Use the top half of the box as a protective cover to prevent dust or debris
from getting inside the unit prior to installation of the decorative cover or
when applying ceiling materials.
3.7. Confirming the position of main unit and
tightening the suspension bolts (Fig. 3-8)
• Using the gauge attached to the grille, ensure that the bottom of the main unit is
properly aligned with the opening of the ceiling. Be sure to confirm this, otherwise
condensation may form and drip due to air leakage, etc.
• Confirm that the main unit is horizontally levelled, using a level or a vinyl tube
filled with water.
• After checking the position of the main unit, tighten the nuts of the suspension
bolts securely to fasten the main unit.
• The installation template (top of the package) can be used as a protective sheet
to prevent dust from entering the main unit when the grilles are left unattached for

4. Installing the refrigerant piping
4.1. Precautions
For devices that use R410A refrigerant
• Use ester oil, ether oil or alkylbenzene oil (small amount) as the refrigeration 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 thicknesses specified 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
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.
