►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.
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.
Contents
Warning:
• Ask the dealer or an authorized technician to install the air conditioner.
• Install the unit at a place that can withstand its weight.
• 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.
• Use only accessories authorized by Mitsubishi Electric and ask the dealer
or an authorized technician to install them.
• Do not touch the heat exchanger fins.
• Install the air conditioner according to this Installation Manual.
• Have all electric work done by a licensed electrician according to local
regulations.
• If the air conditioner is installed in a small room, measures must be taken
to prevent the refrigerant concentration from exceeding the safety limit
even if the refrigerant should leak.
• The cut face punched parts may cause injury by cut, etc. The installers are
requested to wear protective equipement such as gloves, etc.
• 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. Safety precautions
: Indicates an action that must be avoided.
: Indicates that important instructions must be followed.
: Indicates a part which must be grounded.
: Indicates that caution should be taken with rotating parts.
: Indicates that the main power switch must be turned off before servicing.
: Beware of electric shock.
: Beware of hot surface.
ELV
: At servicing, please shut down the power supply for both the Indoor and
Outdoor Unit.
Warning:
Carefully read the labels affixed to the main unit.
Caution:
• Do not use the existing refrigerant piping, when use R410A or R407C
refrigerant.
• Use ester oil, either oil or alkylbenzene (small amount) as the refrigerator
oil to coat flares and flange connections, when use R410A or R407C
refrigerant.
• Do not use the air conditioner where food, pets, plants, precision
instruments, or artwork are kept.
• Do not use the air conditioner in special environments.
• Ground the unit.
• Install an leak molded case circuit braker, as required.
• Use power line cables of sufficient current carrying capacity and rating.
• Use only a molded case circuit braker and fuse of the specified capacity.
• Do not touch the switches with wet fingers.
• Do not touch the refrigerant pipes during and immediately after operation.
• Do not operate the air conditioner with the panels and guards removed.
• Do not turn off the power immediately after stopping operation.

3.2.1. Setting the wall mounting fixture and piping positions
►Using the wall mounting fixture, determine the unit’s installation position
and the locations of the piping holes to be drilled.
Warning:
Before drilling a hole in the wall, you must consult the building contractor.

3.2.2. Drilling the piping hole (Fig. 3-3)
►Use a core drill to make a hole of 75-80 mm diameter in the wall in the
piping direction, at the position shown in the diagram to the left.
►The hole should incline so that the outside opening is lower than the
inside opening.
►Insert a sleeve (with a 75 mm diameter and purchased locally) through the
hole.
Note:
The purpose of the hole’s inclination is to promote drain flow.

3.2.3. Installing the wall mounting fixture
►Since the indoor unit weighs near 13 kg, selection of the mounting
location requires thorough consideration. If the wall does not seem to be
strong enough, reinforce it with boards or beams before installation.
►The mounting fixture must be secured at both ends and at the centre, if
possible. Never fix it at a single spot or in any nonsymetrical way.
(If possible, secure the fixture at all the positions marked with a bold
arrow.)
Warning:
If possible, secure the fixture at all positions indicated with a bold arrow.
Caution:
• The unit body must be mounted horizontally.
• Fasten at the holes marked with ▲as shown by the arrows.

3.3. When embedding pipes into the wall (Fig. 3-5)
• The pipes are on the bottom left.
• When the cooling pipe, drain pipes internal/external connection lines etc are to
be embedded into the wall in advance, the extruding pipes etc, may have to be
bent and have their length modified to suit the unit.
• Use marking on the mount board as a reference when adjusting the length of the
embedded cooling pipe.
• During construction, give the length of the extruding pipes etc some leeway.

3.4. Preparing the indoor unit
* Check beforehand because the preparatory work will differ depending on the
exiting direction of the piping.
* When bending the piping, bend gradually while maintaining the base of the
piping exiting portion. (Abrupt bending will cause misshaping of the piping.)

4.1. Connecting pipes (Fig. 4-1)
• When commercially available copper pipes are used, wrap liquid and gas pipes
with commercially available insulation materials (heat-resistant to 100 °C or
more, thickness of 12 mm or more).
•The indoor parts of the drain pipe should be wrapped with polyethylene foam
insulation materials (specific gravity of 0.03, thickness of 9 mm or more).
• Apply thin layer of refrigerant oil to pipe and joint seating surface before
tightening flare nut.
• Use two wrenches to tighten piping connections.
•Use refrigerant piping insulation provided to insulate indoor unit connections.
Insulate carefully.
Warning:
When installing the unit, securely connect the refrigerant pipes before
starting the compressor.

5. Drainage piping work
5.1. Drainage piping work (Fig. 5-1)
• Drain pipes should have an inclination of 1/100 or more.
• For extension of the drain pipe, use a soft hose (inner dia. 15 mm) available on
the market or hard vinyl chloride pipe (VP-16/O.D. ø22 PVC TUBE). Make sure
that there is no water leakage from the connections.
• Do not put the drain piping directly in a drainage ditch where sulphuric gas may
be generated.
• When piping has been completed, check that water flows from the end of the
drain pipe.
Caution:
The drain pipe should be installed according to this Installation Manual to
ensure correct drainage. Thermal insulation of the drain pipes is necessary
to prevent condensation. If the drain pipes are not properly installed and
insulated, condensation may drip on the ceiling, floor or other possessions.

6.5. Setting addresses (Fig. 6-4)
(Be sure to operate with the main power turned OFF.)
• There are two types of rotary switch setting available: setting addresses 1 to 9
and over 10, and setting branch numbers.
1How to set addresses
Example: If Address is “3”, remain SW12 (for over 10) at “0”, and match SW11
(for 1 to 9) with “3”.
2How to set branch numbers SW14 (Series R2 only)
Match the indoor unit’s refrigerant pipe with the BC controller’s end connection
number.
Remain other than series R2 at “0”.
• The rotary switches are all set to “0” when shipped from the factory. These
switches can be used to set unit addresses and branch numbers at will.
• The determination of indoor unit addresses varies with the system at site. Set
them referring to the Data Book.
6.6. Sensing room temperature with the built-in
sensor in a remote controller
If you want to sense room temperature with the built-in sensor in a remote
controller, set SW1-1 on the control board to “ON”. The setting of SW1-7 and SW1-
8 as necessary also makes it possible to adjust the air flow at a time when the
heating thermometer is OFF.
