Caution:
• Do not vent R410A into the Atmosphere:
• R410A is a Fluorinated Greenhouse gas, covered by the Kyoto Protocol, with a Global Warming Potential (GWP)=1975.
Confirmation 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 precau-
tions".
► Please report to or take consent by the supply authority before connec-
tion to the system.
► Equipment complying with IEC/EN 61000-3-12
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 authorized
technician to install the unit. If the unit is installed incorrectly, water leakage,
electric shock, or fire may result.
• For installation work, follow the instructions in the Installation Manual and use
tools and pipe components specifically made for use with R410A refrigerant.
The R410A refrigerant in the HFC system is pressurized 1.6 times the pressure
of usual refrigerants. If pipe components not designed for R410A refrigerant are
used and the unit is not installed correctly, the pipes may burst and cause dam-
age or injuries. In addition, water leakage, electric shock, or fire may result.
• The unit must be installed according to the instructions in order to minimize
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
prevent the refrigerant concentration in the room from exceeding the safety
limit in the event of refrigerant leakage. Consult a dealer regarding the appro-
priate measures to prevent the allowable concentration from being exceeded.
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. The units must be
powered by dedicated power lines and the correct voltage and circuit breakers
must be used. Power lines with insufficient capacity or incorrect electrical
work may result in electric shock or fire.
• Use C1220 copper phosphorus, for copper and copper alloy seamless pipes,
to connect the refrigerant pipes. If the pipes are not connected correctly, the
unit will not be properly grounded and electric shock may result.

Grounding lead wire (× 2)
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.
• 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 outdoor unit must be firmly attached. If
the cover panel is mounted incorrectly and dust and moisture enter the unit,
electric shock or fire may result.
• 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.
• Use only accessories authorized by Mitsubishi Electric and ask a dealer or an
authorized technician to install them. If accessories are incorrectly installed,
water leakage, electric shock, or fire 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 fire may result.
• The user should never attempt to repair the unit or transfer it to another loca-
tion. If the unit is installed incorrectly, water leakage, electric shock, or fire
may result. If the air conditioner must be repaired or moved, ask a dealer or
an authorized technician.
• After installation has been completed, check for refrigerant leaks. If refriger-
ant leaks into the room and comes into contact with the flame of a heater or
portable cooking range, poisonous gases will be released.
