Con rmation of parts attached
In addition to this manual, the following parts are supplied with the outdoor unit.
They are used for grounding the S terminals of transmission terminal blocks TB3, TB7.
For details refer to "6. Electrical work".

1. Safety precautions

Before installing the unit, make sure you read all the "Safety precautions".
Please report to or take consent by the supply authority before connec-
tion to the 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.
Warning:
The unit must not be installed by the user. Ask a dealer or an authori ed
technician to install the unit. If the unit is installed incorrectly, water leakage,
electric shock, or re may result.
For installation work, follow the instructions in the Installation Manual and use
tools and pipe components speci cally made for use with R 10A refrigerant.
The R 10A refrigerant in the FC system is pressuri ed 1.6 times the pres-
sure of usual refrigerants. If pipe components not designed for R 10A refrig-
erant are used and the unit is not installed correctly, the pipes may burst and
cause damage or in uries. In addition, water leakage, electric shock, or re
may result.
The unit must be installed according to the instructions in order to minimi e
the risk of damage from earthquakes, typhoons, or strong winds. An incor-
rectly 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 unit is mounted on an unstable structure, it may fall down and cause
damage or injuries.
If the air conditioner is installed in a small room, measures must be taken to
pre ent the refrigerant concentration in the room from e ceeding the safety limit
in the event of refrigerant leakage. Consult a dealer regarding the appropriate
measures to prevent the allowable concentration from being e ceeded.
Should the refrigerant leak and cause the concentration limit to be e ceeded,
ha ards due to lack of o ygen in the room may result.
entilate 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. The units must
be powered by dedicated power lines and the correct voltage and circuit
breakers must be used. Power lines with insuf cient capacity or incorrect
electrical work may result in electric shock or re.
Be sure to connect the power supply cords and the connecting wires for
the indoor units, outdoor units, and branch bo es directly to the units (no
intermediate connections).
1.1. Before installation
Caution:
Do not use the unit in an unusual environment. If the air conditioner is
installed in areas e posed to steam, volatile oil (including machine oil), or
sulfuric gas, areas e posed to high salt content such as the seaside, or areas
where the unit will be covered by snow, 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
e plosion may result.
1. . Before installation (relocation)
Caution:
Be e tremely careful when transporting the units.
needed to handle the unit, as it weighs 0 kg,
the packaging bands. Wear protective gloves to remove the unit from the
packaging and to move it, as you can injure your hands on the ns or the
edge of 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.

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 af
Intermediate connections can lead to communication errors if water enters
the cords or wires and causes insuf cient insulation to ground or a poor
electrical contact at the intermediate connection point.
(If an intermediate connection is necessary, be sure to take measures to
prevent water from entering the cords and wires.)
Use C1
to connect the refrigerant pipes. If the pipes are not connected correctly, the
unit will not be properly grounded and electric shock may result.
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.
The terminal block cover panel of the outdoor unit must be rmly attached. If
the cover panel is mounted incorrectly and dust and moisture enter the unit,
electric shock or re may result.
When installing or relocating, or servicing the outdoor unit, use only the
speci ed refrigerant (R 10A) to change the refrigerant lines. Do not mi it
with any other refrigerant and do not allow air to remain in the lines.
If air is mi ed with the refrigerant, then it can be the cause of abnormal high pres-
sure in the refrigerant line, and may result in an e plosion and other ha ards.
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.
Use only accessories authori ed by Mitsubishi Electric and ask a dealer
or an authori ed technician to install them. If accessories are incorrectly
installed, water leakage, electric shock, or re may result.
Do not alter the unit. Consult a dealer for repairs. If alterations or repairs are
not performed correctly, water leakage, electric shock, or re may result.
The user should never attempt to repair the unit or transfer it to another location.
If the unit is installed incorrectly, water leakage, electric shock, or re may
result. If the air conditioner must be repaired or moved, ask a dealer or an
authori ed technician.
After installation has been completed, check for refrigerant leaks. If refriger-
ant leaks into the room and comes into contact with the ame of a heater or
portable cooking range, poisonous gases will be released.
The outdoor unit produces condensation during the heating operation. Make
sure to provide drainage around the outdoor unit if such condensation is
likely to 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 communi-
cations equipment, harming the screen display quality.
or more persons are The base and attachments of the outdoor unit must be periodically checked
lbs or more. Do not grasp for looseness, cracks or other damage. If such defects are left uncorrected,
the unit may fall down and cause damage or injuries.
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 e tended period and refrigerant can
leak out.
