Warning:
• The unit must not be installed by the user. Ask a dealer or an authorized technician to install and repair the unit. If the unit is installed incorrectly, water leakage,
electric shock, or re may result.
• For installation and relocation work, follow the instructions in the Installation
Manual and use tools and pipe components specically 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 re 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 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 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 ame, poisonous gases will be released.
• All electric work must be performed by a qualied 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 insufcient capacity or incorrect electrical work may result
in electric shock or re.
• 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 specied 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.
• If the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualied 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 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 air conditioner, use only the specied 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.
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 specied 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 authorized 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 authorized
technician.
• After installation has been completed, check for refrigerant leaks. If refrigerant
leaks into the room and comes into contact with the ame 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 ames, 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 sufciently.
Make sure that there are no hazardous or ammable 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 specied for operation.
/ Keep gas-burning appliances, electric heaters, and other re sources (ignition
sources) away from the location where installation, repair, and other air conditioner work will be performed.
If refrigerant comes into contact with a ame, poisonous gases will be released.
/ Do not smoke during work and transportation.

1. Safety precautions
1.1. Before installation
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, or areas where the unit will be
covered by snow, the performance can be signicantly 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 explosion
may result.
1.2. Before installation (relocation)
Caution:
• Be extremely careful when transporting or installing 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 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.
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 sufcient capacity. Otherwise, a short
circuit, overheating, or re may result.
• When installing the power lines, do not apply tension to the cables. If the connections are loosened, the cables can snap or break and overheating or re may
result.
1.4. Before starting the test run
Caution:
• Turn on the main power switch more than 12 hours before starting operation.
Starting operation just after turning on the power switch can severely damage
the internal parts. Keep the main power switch turned on during the operation
season.
• Before starting operation, check that all panels, guards and other protective parts
are correctly installed. Rotating, hot, or high voltage parts can cause injuries.
• 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 ofce, 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.
• The base and attachments of the outdoor unit must be periodically checked 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 specication using a torque wrench. If tightened too
much, the are nut can break after an extended period and refrigerant can leak
out.
• Be sure to ground the unit. Do not connect the ground wire to gas or water pipes,
lightning rods, or telephone grounding lines. 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 specied capacity. If the circuit breaker
capacity is larger than the specied capacity, breakdown or re 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. The refrigerant pipes are hot or cold depending on the condition of the owing refrigerant. If
you touch the pipes, burns or frostbite may result.
• After stopping operation, be sure to wait at least ve minutes before turning off
the main power switch. Otherwise, water leakage or breakdown may result.
1.5. Using R32 refrigerant air conditioners
Caution:
• Use C1220 copper phosphorus, for copper and copper alloy seamless pipes, to
connect the refrigerant pipes. Make sure the insides of the pipes are clean and
do not contain any harmful contaminants such as sulfuric compounds, oxidants,
debris, or dust. Use pipes with the specied thickness. (Refer to 4.1.) Note the
following if reusing existing pipes that carried R22 refrigerant.
- Replace the existing are nuts and are the ared sections again.
- Do not use thin pipes. (Refer to 4.1.)
• Store the pipes to be used during installation indoors and keep both ends of the
pipes sealed until just before brazing. (Leave elbow joints, etc. in their packaging.) If dust, debris, or moisture enters the refrigerant lines, oil deterioration or
compressor breakdown may result.
• Use ester oil, ether oil, alkylbenzene oil (small amount) as the refrigeration oil
applied to the ared sections. If mineral oil is mixed in the refrigeration oil, oil
deterioration may result.
• Do not use refrigerant other than R32 refrigerant.

2.2. Choosing the outdoor unit installation location
/ R32 is heavier than air—as well as other refrigerants—so tends to accumulate at
the base (in the vicinity of the oor). If R32 accumulates around base, it may reach
a ammable concentration in case room is small. To avoid ignition, maintaining a
safe work environment is required by ensuring appropriate ventilation. If a refrig-
erant leak is conrmed in a room or an area where there is insufcient ventilation,
refrain from using of ames until the work environment can be improved by ensur-
ing appropriate ventilation.
• Avoid locations exposed to direct sunlight or other sources of heat.
• Select a location from which noise emitted by the unit will not inconvenience
neighbors.
• Select a location permitting easy wiring and pipe access to the power source and
indoor unit.
• Avoid locations where combustible gases may leak, be produced, ow, or accu-
mulate.
• Note that water may drain from the unit during operation.
• Select a level location that can bear the weight and vibration of the unit.
• Avoid locations where the unit can be covered by snow. In areas where heavy
snow fall is anticipated, special precautions such as raising the installation location or installing a hood on the air intake must be taken to prevent the snow from
blocking the air intake or blowing directly against it. This can reduce the airow
and a malfunction may result.
• Avoid locations exposed to oil, steam, or sulfuric gas.
• Use the transportation handles of the outdoor unit to transport the unit. If the unit
is carried from the bottom, hands or ngers may be pinched.
• Refrigerant pipes connection shall be accessible for maintenance purposes.
/ Install outdoor units in a place where at least one of the four sides is open, and in
a sufciently large space without depressions. (Fig. 2-2)
2.3. Outline dimensions (Outdoor unit) (Fig. 2-3)
2.4. Ventilation and service space
2.4.1. Windy location installation
When installing the outdoor unit on a rooftop or other location unprotected from the
wind, situate the air outlet of the unit so that it is not directly exposed to strong winds.
Strong wind entering the air outlet may impede the normal airow and a malfunction
may result.
The following shows three examples of precautions against strong winds.
1 Face the air outlet towards the nearest available wall about 500 mm away from
the wall. (Fig. 2-4)
2 Install an optional air guide if the unit is installed in a location where strong winds
from a typhoon, etc. may directly enter the air outlet. (Fig. 2-5)
