Before installing the unit, make sure you read all the “Safety precautions”.

► Please report to or take consent by the supply authority before connec-

tion to the system.

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.

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 affi xed to the main unit.

Warning:

• The unit must not be installed by the user. Ask a dealer or an authorized

technician to install the unit. If the unit is installed incorrectly, water leak­age, electric shock, or fi re may result.

• For installation work, follow the instructions in the Installation Manual and

use tools and pipe components specifi cally made for use with R410A re-
frigerant. The R410A refrigerant in the HFC system is pressurized 1.6 times
the pressure of usual refrigerants. If pipe components not designed for
R410A 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 fi re may result.

• The unit must be installed according to the instructions in order to mini-

mize 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 fl ame, poisonous gases will be released.

• All electric work must be performed by a qualifi ed 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 insuffi cient capacity or incorrect
electrical work may result in electric shock or fi 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 specifi ed 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 fi re.

• The terminal block cover panel of the outdoor unit must be fi rmly attached.
If the cover panel is mounted incorrectly and dust and moisture enter the
unit, electric shock or fi re may result.

• When installing or relocating, or servicing the outdoor unit, use only the
specifi ed refrigerant (R410A) 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 pressure 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 mechanical 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 fi 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 fi re may re-
sult.

• 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 fi 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 fl ame of a heater
or portable cooking range, poisonous gases will be released.

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 sig­nifi cantly reduced and the internal parts can be damaged.

• Do not install the unit where combustible gases may leak, be produced,
fl ow, or accumulate. If combustible gas accumulates around the unit, fi re
or explosion may result.

2

• 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 office, 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.

1. Safety precautions

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 fi 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 suffi cient capacity. Otherwise,
a short circuit, overheating, or fi 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 fi 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.

• Do not touch any switch with wet hands. Electric shock may result.

• 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 fl are nuts to specifi cation using a torque wrench. If tightened
too much, the fl 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 specifi ed capacity. If the circuit
breaker capacity is larger than the specifi ed capacity, breakdown or fi re
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 fl owing
refrigerant. If you touch the pipes, burns or frostbite may result.

• After stopping operation, be sure to wait at least fi ve minutes before turn-
ing off the main power switch. Otherwise, water leakage or breakdown may
result.

1.5. Using R410A 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 specifi ed thick-
ness. (Refer to 4.1.) Note the following if reusing existing pipes that carried
R22 refrigerant.

- Replace the existing fl are nuts and fl are the fl 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 fl ared sections. If mineral oil is mixed in the refrigeration
oil, oil deterioration may result.

• Do not use refrigerant other than R410A refrigerant. If another refrigerant is
used, the chlorine will cause the oil to deteriorate.

• Use the following tools specifi cally designed for use with R410A refrigerant.
The following tools are necessary to use R410A refrigerant. Contact your
nearest dealer for any questions.

Gauge manifold Flare tool

Charge hose Size adjustment gauge

Gas leak detector Vacuum pump adapter

Torque wrench Electronic refrigerant charging scale

• Be sure to use the correct tools. If dust, debris, or moisture enters the re-

frigerant lines, refrigeration oil deterioration may result.

• Do not use a charging cylinder. If a charging cylinder is used, the compo-

sition of the refrigerant will change and the effi ciency will be lowered.

2.2. Choosing the outdoor unit installation location

• 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, fl 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 airfl 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 fi ngers may be pinched.
