- Improper handling may result in injury.
• If refrigerant gas leaks during installation work,
ventilate the room.
- If the refrigerant gas comes into contact with a ame,
poisonous gases will be released.
• InstalltheunitaccordingtothisInstallationManu-
al.
- If the unit is installed improperly, water leakage,
electric shock, or re may result.
• Have all electric work done by a licensed electri-
cianaccordingto“ElectricFacilityEngineering
Standard” and “Interior Wire Regulations”and the
instructions given in this manual and always use
a special circuit.
- If the power source capacity is inadequate or electric
work is performed improperly, electric shock and re
may result.
• Keep the electric parts away from water (washing
water etc.).
- It might result in electric shock, catching re or
smoke.
• Securely install the heat source unit terminal
cover (panel).
- If the terminal cover (panel) is not installed properly,
dust or water may enter the heat source unit and re
or electric shock may result.
• When installing and moving the air conditioner
to another site, do not charge it with a refrigerant
differentfromtherefrigerant(R410A)speciedon
the unit.
- If a different refrigerant or air is mixed with the origi-
nal refrigerant, the refrigerant cycle may malfunction
and the unit may be damaged.
• If the air conditioner is installed in a small room,
measures must be taken to prevent the refriger-
ant concentration from exceeding the safety limit
even if the refrigerant should leak.
- Consult the dealer regarding the appropriate meas-
ures to prevent the safety limit from being exceeded.
Should the refrigerant leak and cause the safety
limit to be exceeded, hazards due to lack of oxygen
in the room could result.
• When moving and reinstalling the air conditioner,
consult the dealer or an authorized technician.
- If the air conditioner is installed improperly, water
leakage, electric shock, or re may result.

- ii -
• Do not use the existing refrigerant piping.
- The old refrigerant and refrigerant oil in the existing
piping contains a large amount of chlorine which
may cause the refrigerant oil of the new unit to dete-
riorate.
- R410A is a high-pressure refrigerant and can cause
the existing piping to burst.
• Use refrigerant piping made of C1220 (CU-DHP)
phosphorusdeoxidizedcopperasspeciedinthe
JIS H3300 “Copper and copper alloy seamless
pipes and tubes”. In addition, be sure that the in-
ner and outer surfaces of the pipes are clean and
free of hazardous sulphur, oxides, dust/dirt, shav-
ing particles, oils, moisture, or any other contami-
nant.
- Contaminants on the inside of the refrigerant piping
may cause the refrigerant residual oil to deteriorate.
• Store the piping to be used during installation
indoors and keep both ends of the piping sealed
until just before brazing. (Store elbows and other
joints in a plastic bag.)
- If dust, dirt, or water enters the refrigerant cycle,
deterioration of the oil and compressor trouble may
result.
• Use ester oil, ether oil or alkylbenzene (small
amount)astherefrigerantoiltocoataresand
angeconnections.
- The refrigerant oil will degrade if it is mixed with a
large amount of mineral oil.
• Useliquidrefrigeranttollthesystem.
- If gas refrigerant is used to seal the system, the
composition of the refrigerant in the cylinder will
change and performance may drop.
• Do not use a refrigerant other than R410A.
- If another refrigerant (R22, etc.) is mixed with
R410A, the chlorine in the refrigerant may cause the
refrigerant oil to deteriorate.
• Useavacuumpumpwithareverseowcheck
valve.
- The vacuum pump oil may ow back into the refrig-
erant cycle and cause the refrigerant oil to deterio-
rate.
• Do not use the following tools that are used with
conventional refrigerants.
 (Gaugemanifold,chargehose,gasleakdetector,
reverseowcheckvalve,refrigerantchargebase,
refrigerant recovery equipment)
- If the conventional refrigerant and refrigerant oil are
mixed in the R410A, the refrigerant may deterio-
rated.
-If water is mixed in the R410A, the refrigerant oil
may deteriorate.
- Since R410A does not contain any chlorine, gas
leak detectors for conventional refrigerants will not
react to it.
• Do not use a charging cylinder.
- Using a charging cylinder may cause the refrigerant
to deteriorate.
• Be especially careful when managing the tools.
- If dust, dirt, or water gets in the refrigerant cycle, the
refrigerant may deteriorate.
• After completing installation work, make sure that
refrigerant gas is not leaking.
- If the refrigerant gas leaks and is exposed to a fan
heater, stove, oven, or other heat source, it may gen-
erate noxious gases.
• Do not reconstruct or change the settings of the
protection devices.
- If the pressure switch, thermal switch, or other
protection device is shorted and operated forcibly,
or parts other than those specied by Mitsubishi
Electric are used, re or explosion may result.
• To dispose of this product, consult your dealer.
• The installer and system specialist shall secure
safety against leakage according to local regula-
tion or standards.
- Following standards may be applicable if local regu-
lation are not available.
• Pay a special attention to the place, such as a
basement, etc. where refrigeration gas can stay,
since refrigeration is heavier than the air.

- iii -
• Do not install the unit where combustible gas may
leak.
- If the gas leaks and accumulates around the unit, an
explosion may result.
• Do not use the air conditioner where food, pets,
plants, precision instruments, or artwork are kept.
- The quality of the food, etc. may deteriorate.
• Do not use the air conditioner in special environ-
ments.
- Oil, steam, sulfuric smoke, etc. can signicantly reduce
the performance of the air conditioner or damage its
parts.
• When installing the unit in a hospital, communica-
tionstation,orsimilarplace,providesufcient
protection against noise.
- The inverter equipment, private power generator,
high-frequency medical equipment, or radio commu-
nication equipment may cause the air conditioner to
operate erroneously, or fail to operate. On the other
hand, the air conditioner may affect such equipment
by creating noise that disturbs medical treatment or
image broadcasting.
• Do not install the unit on a structure that may
cause leakage.
- When the room humidity exceeds 80 % or when the
drain pipe is clogged, condensation may drip from
the indoor unit. Perform collective drainage work
together with the unit, as required.

- iv -
• Groundtheunit.
- Do not connect the ground wire to gas or water
pipes, lightning rods, or telephone ground lines.
Improper grounding may result in electric shock.
• Install the power cable so that tension is not
applied to the cable.
- Tension may cause the cable to break and generate
heat and cause a re.
• Install a leak circuit breaker, as required.
- If a leak circuit breaker is not installed, electric shock
may result.
• Usepowerlinecablesofsufcientcurrent
carrying capacity and rating.
- Cables that are too small may leak, generate heat,
and cause a re.
• Use only a circuit breaker and fuse of the
speciedcapacity.
- A fuse or circuit breaker of a larger capacity or a
steel or copper wire may result in a general unit
failure or re.
• Do not wash the air conditioner units.
- Washing them may cause an electric shock.
• Be careful that the installation base is not
damaged by long use.
- If the damage is left uncorrected, the unit may fall
and cause personal injury or property damage.
• Install the drain piping according to this
InstallationManualtoensureproperdrainage.
Wrap thermal insulation around the pipes to
prevent condensation.
- Improper drain piping may cause water leakage and
damage to furniture and other possessions.
• Be very careful about product transportation.
- Only one person should not carry the product if it
weighs more than 20 kg.
- Some products use PP bands for packaging. Do not
use any PP bands for a means of transportation. It
is dangerous.
- When transporting the unit, support it at the
specied positions on the unit base. Also support the
unit at four points so that it cannot slip side ways.
• Safely dispose of the packing materials.
- Packing materials, such as nails and other metal or
wooden parts, may cause stabs or other injuries.
- Tear apart and throw away plastic packaging bags
so that children will not play with them. If children
play with a plastic bag which was not torn apart,
they face the risk of suffocation.

- v -
• Turn on the power at least 12 hours before
starting operation.
- Starting operation immediately after turning on the
main power switch can result in severe damage
to internal parts. Keep the power switch turned on
during the operational season.
• Donottouchtheswitcheswithwetngers.
- Touching a switch with wet ngers can cause elec-
tric shock.
• Do not touch the refrigerant pipes during and im-
mediately after operation.
- During and immediately after operation, the
refrigerant pipes are may be hot and may be cold,
depending on the condition of the refrigerant owing
through the refrigerant piping, compressor, and
other refrigerant cycle parts. Your hands may suffer
burns or frostbite if you touch the refrigerant pipes.
• Do not operate the air conditioner with the panels
and guards removed.
- Rotating, hot, or high-voltage parts can cause
injuries.
• Do not turn off the power immediately after
stopping operation.
- Always wait at least ve minutes before turning off
the power. Otherwise, water leakage and trouble
may occur.
• Do not touch the surface of the compressor
during servicing.
- If unit is connected to the supply and not running,
crank case heater at compressor is operating.
• Do not touch the panels near the fan exhaust
outletwithbarehands:theycangethotwhile
the unit is in operation (even if it is stopped) or
immediately after operation and poses a risk of
burns. Wear gloves to protect your hands when it
is necessary to touch the panels.
• While the unit is in operation or immediately after
operation, high-temperature exhaust air may blow
out of the fan exhaust outlet. Do not hold your
hands over the outlet or touch the panels near the
outlet.
• Be sure to provide a pathway for the exhaust air
from the fan.
• Water pipes can get very hot, depending on the
preset temperature. Wrap the water pipes with
insulating materials to prevent burns.
