Warning:
• The unit must not be installed by the user. Ask a dealer or an authoried
technician 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 Installa-
tion Manual and use tools and pipe components speciically made or use
with R32 rerigerant. I pipe components not designed or R32 rerigerant
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 minimie
the risk o damage rom 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. I the unit is mounted on an unstable structure, it may all down and
cause damage or injuries.
• I the air conditioner is installed in a small room, measures must be taken
to prevent the rerigerant concentration in the room rom eceeding the
saety limit in the event o rerigerant leakage. Consult a dealer regarding
the appropriate measures to prevent the allowable concentration rom being
eceeded. Should the rerigerant leak and cause the concentration limit to
be eceeded, haards due to lack o oygen in the room may result.
•Ventilate the room if refrigerant leaks during operation. If refrigerant comes
into contact with a lame, poisonous gases will be released.
• All electric work must be perormed by a qualiied 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 insuicient capacity or incorrect
electrical work may result in electric shock or fire.
• Use C1220 copper phosphorus, or 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.
• This appliance is intended to be used by epert or trained users in shops, in
light industry and on arms, or or commercial use by lay persons.
• Use only speciied cables or wiring. The wiring connections must be made
securely with no tension applied on the terminal connections. Also, never
splice the cables or wiring (unless otherwise indicated in this document).
Failure to observe these instructions may result in overheating or a ire.
• I the supply cord is damaged, it must be replaced by the manuacturer, its
service agent or similarly qualiied persons in order to avoid haard.
•
The appliance shall be installed in accordance with national wiring regulations.
• The terminal block cover panel o the outdoor unit must be irmly attached.
I the cover panel is mounted incorrectly and dust and moisture enter the
unit, electric shock or fire may result.
• hen installing or relocating, or servicing the air conditioner, use only the
speciied rerigerant (R32) to charge the rerigerant lines. Do not mi it with
any other refrigerant and do not allow air to remain in the lines.
I air is mied with the rerigerant, then it can be the cause o abnormal high
pressure in the rerigerant line, and may result in an eplosion and other
haards.
The use of any refrigerant other than that specified for the system will cause
mechanical ailure or system malunction 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. I accessories are incorrectly
installed, water leakage, electric shock, or fire may result.

1. Safety precautions
1.1. Before installation
Caution:
• Do not use the unit in an unusual environment. I the air conditioner is in-
stalled in areas eposed to steam, volatile oil (including machine oil), or
suluric gas, areas eposed to high salt content such as the seaside, or
areas where the unit will be covered by snow, the perormance can be sig-
nicantly reduced and the internal parts can be damaged.
• Do not install the unit where combustible gases may leak, be produced,
ow, or accumulate. I combustible gas accumulates around the unit, re or
eplosion may result.
•The outdoor unit produces condensation during the heating operation.
Make sure to provide drainage around the outdoor unit i such condensa-
tion is likely to cause damage.
• hen installing the unit in a hospital or communications oce, be prepared
or noise and electronic intererence. Inverters, home appliances, high-
frequency medical equipment, and radio communications equipment can
cause the air conditioner to malunction or breakdown. The air conditioner
may also aect medical equipment, disturbing medical care, and communi-
cations equipment, harming the screen display quality.
1.2. Beore installation (relocation)
Caution:
• Be etremely careul 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. ear protective gloves to remove the unit rom
the packaging and to move it, as you can inure your hands on the ns or
the edge of other parts.
• Be sure to saely dispose o the packaging materials. Packaging materials,
such as nails and other metal or wooden parts may cause stabs or other
injuries.
• The base and attachments o 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 specication using a torque wrench. I tightened too
much, the are nut can break ater an etended period and rerigerant can
leak out.
1.3. Beore electric work
Caution:
• Be sure to install circuit breakers. I not installed, electric shock may result.
• For the power lines, use standard cables o sucient capacity. Otherwise,
a short circuit, overheating, or re may result.
• hen installing the power lines, do not apply tension to the cables. I the
connections are loosened, the cables can snap or break and overheating or
re may result.
• 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 prop-
erly grounded, electric shock may result.
• Use circuit breakers (ground ault interrupter, isolating switch (B use),
and molded case circuit breaker) with the specied capacity. I the circuit
breaker capacity is larger than the specied capacity, breakdown or re
may result.
1.4. Beore starting the test run
Caution:
• Turn on the main power switch more than 12 hours beore starting opera-
tion. Starting operation ust ater turning on the power switch can severely
damage the internal parts. Keep the main power switch turned on during the
operation season.
• Beore starting operation, check that all panels, guards and other protective
parts are correctly installed. Rotating, hot, or high voltage parts can cause
injuries.
• Do not touch any switch with wet hands. Electric shock may result.
• Do not touch the rerigerant pipes with bare hands during operation. The
rerigerant pipes are hot or cold depending on the condition o the owing
rerigerant. I you touch the pipes, burns or rostbite may result.
• Ater stopping operation, be sure to wait at least ve minutes beore turn-
ing o the main power switch. Otherwise, water leakage or breakdown may
result.
1.5. Using R32 rerigerant air conditioners
Caution:
• Use C1220 copper phosphorus, or copper and copper alloy seamless
pipes, to connect the rerigerant pipes. Make sure the insides o the pipes
are clean and do not contain any harmful contaminants such as sulfuric
compounds, oidants, debris, or dust. Use pipes with the specied thick-
ness. (Reer to 4.1.) Note the ollowing i reusing eisting pipes that carried
R22 rerigerant.
- 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
o the pipes sealed until ust beore braing. (Leave elbow oints, etc. in
their packaging.) I dust, debris, or moisture enters the rerigerant lines, oil
deterioration or compressor breakdown may result.
• Use ester oil, ether oil, alkylbenene oil (small amount) as the rerigeration
oil applied to the ared sections. I mineral oil is mied in the rerigeration
oil, oil deterioration may result.
• Servicing shall be perormed only as recommended by the manuacturer.
• Do not use rerigerant other than R32 rerigerant. I another rerigerant is
used, the chlorine will cause the oil to deteriorate.
• Use the ollowing tools specically designed or use with R32 rerigerant.
The ollowing tools are necessary to use R32 rerigerant. Contact your near-
est dealer for any questions.

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 conrmed in a room or an area where there is insufcient 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 loca-
tion 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 airow
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 sufciently large space without depressions. (Fig. 2-2)
