• The water circuit should be a closed circuit.
• Ask the dealer or an authorized technician to
install the air conditioner.
- Improper installation by the user may result in water
leakage, electric shock, or fire.
• Install the unit in a place that can withstand its
weight.
- Inadequate strength may cause the unit to fall down,
resulting in injuries.
• Do not touch the unit. The unit surface can be hot.
• Do not install the unit where corrosive gas is
generated.
• Use the specifi ed cables for wiring. Make the
connections securely so that the outside force of
the cable is not applied to the terminals.
- Inadequate connection and fastening may generate
heat and cause a fire.
• Prepare for rain and other moisture and
earthquakes and install the unit at the specifi ed
place.
- Improper installation may cause the unit to topple
and result in injury.
• Always use an strainer and other accessories
specifi ed by Mitsubishi Electric.
- Ask an authorized technician to install the accesso-
ries. Improper installation by the user may result in
water leakage, electric shock, or fire.
• Never repair the unit. If the air conditioner must
be repaired, consult the dealer.
- If the unit is repaired improperly, water leakage,
electric shock, or fire may result.
• Do not touch the refrigerant pipes and Water
pipes.
- Improper handling may result in injury.
• When handling this product, always wear protec-
tive equipment.
EG: Gloves, full arm protection namely boiler suit,
and safety glasses.
- 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 flame,
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 fire 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 fire
may result.
• Keep the electric parts away from water (washing
water etc.).
- It might result in electric shock, catching fire 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 fire
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) specifi 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 fire 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 specifi 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.
• Apply a small amount of ester oil, ether oil, or
alkyl benzene to fl ares. (for indoor unit)
- Infiltration of a large amount of mineral oil may
cause the refrigerant oil to deteriorate.
• Use liquid refrigerant to fi 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 fl ow check
valve.
- The vacuum pump oil may flow 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 fl 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.
• Do not use antioxidant or leak-detection additive.
• 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 specified by Mitsubishi
Electric are used, fire 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 significantly 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 suffi 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 fire.
• Install a leak circuit breaker, as required.
- If a leak circuit breaker is not installed, electric shock
may result.
• Use power line cables of suffi cient current
carrying capacity and rating.
- Cables that are too small may leak, generate heat,
and cause a fire.
• Use only a circuit breaker and fuse of the
specifi 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 fire.
• 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 damage property.
• 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.
- If the unit weighs more than 20kg, carry the unit with
more than one person.
- 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 specified
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 it is out of reach of children. 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 fi ngers.
- Touching a switch with wet fingers 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 flowing
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 five 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 outlet with
bare hands: they can get hot while the unit is in
operation (even if it is stopped) or immediately
after operation to prevent 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.
