Caution:
• Do not vent R32 into the atmosphere.
1. Safety precautions
► Before installing the unit, make sure you read all the "Safety precautions".
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.
MEANINGS OF SYMBOLS DISPLAYED ON THE UNIT
WARNING
(Risk of fire)
Read the OPERATION MANUAL carefully before operation.
Service personnel are required to carefully read the OPERATION MANUAL and INSTALLATION MANUAL before operation.
Further information is available in the OPERATION MANUAL, INSTALLATION MANUAL, and the like.
Warning:
• The unit must not be installed by the user. Ask a dealer or an authorized techni-
cian to install and repair the unit. If the unit is installed incorrectly, water leakage,
electric shock, or fire may result.
• For installation and relocation work, follow the instructions in the Installation
Manual and use tools and pipe components specifically made for use with R32
refrigerant. If pipe components not designed for R32 refrigerant are used and the
unit is not installed correctly, the pipes may burst and cause damage 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 incorrectly in-
stalled 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 appropriate
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.
• Use only specified cables for wiring. The wiring connections must be made se-
curely 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.
• If the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualified persons in order to avoid hazard.
• The appliance shall be installed in accordance with national wiring regulations.
• 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 speci-
fied refrigerant (R32) to charge the refrigerant lines. Do not mix it with any other
refrigerant and do not allow air to remain in the lines.
This mark is for R32 refrigerant only. Refrigerant type is written on nameplate of outdoor unit.
In case that refrigerant type is R32, this unit uses a flammable refrigerant.
If refrigerant leaks and comes in contact with fire or heating part, it will create harmful gas and there is risk of fire.

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.
: Indicates warnings and cautions when using R32 refrigerant.
/
If air is mixed with the refrigerant, then it can be the cause of abnormal high pres-
sure 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 me-
chanical 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 au-
thorized technician to install them. If accessories are incorrectly installed, water
leakage, electric shock, or fire may result.
• Do not alter the unit. It may cause fire, electric shock, injury or water leakage.
• 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 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 refrigerant
leaks into the room and comes into contact with the flame of a heater or portable
cooking range, poisonous gases will be released.
• Do not use means to accelerate the defrosting process or to clean, other than
those recommended by the manufacturer.
• The appliance shall be stored in a room without continuously operating ignition
sources (for example: open flames, an operating gas appliance or an operating
electric heater).
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
/ Pipe-work shall be protected from physical damage.
• The installation of pipe-work shall be kept to a minimum.
• Compliance with national gas regulations shall be observed.
• Keep any required ventilation openings clear of obstruction.
/ Do not use low temperature solder alloy in case of brazing the refrigerant pipes.
/ When performing brazing work, be sure to ventilate the room sufficiently.
Make sure that there are no hazardous or flammable materials nearby.
When performing the work in a closed room, small room, or similar location, make
sure that there are no refrigerant leaks before performing the work.
If refrigerant leaks and accumulates, it may ignite or poisonous gases may be
released.
/ The appliance shall be stored in a well-ventilated area where the room size cor-
responds to the room area as specified for operation.
/ Keep gas-burning appliances, electric heaters, and other fire sources (ignition
sources) away from the location where installation, repair, and other air condi-
tioner work will be performed.
If refrigerant comes into contact with a flame, poisonous gases will be released.
/ Do not smoke during work and transportation.
