tions”.
s 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.
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 fire may result.
• For installation work, follow the instructions in the Installation Manual and use
tools and pipe components specifically made for use with R410A refrigerant.
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 fire 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 flame, poisonous gases will be released.
• All electric work must be performed by a qualified 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 insufficient capacity or incorrect electrical work may result in electric shock or fire.
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 affixed to the main unit.
• 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 specified cables for wiring. The connections must be made securely
without tension on the terminals. If the cables are connected or installed incorrectly, overheating or fire may result.
• The terminal block cover panel of the outdoor unit must be firmly attached. If
the cover panel is mounted incorrectly and dust and moisture enter the unit,
electric shock or fire may result.
• When installing or moving the air conditioner, use only the specified 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. Air enclosed in the lines can
cause pressure peaks resulting in a rupture and other hazards.
• 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 fire 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 fire 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 fire
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 flame of a heater or
portable cooking range, poisonous gases will be released.

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 significantly reduced and the internal parts can be damaged.
• Do not install the unit where combustible gases may leak, be produced, flow,
or accumulate. If combustible gas accumulates around the unit, fire or explosion may result.
• 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.
1.2. Before installation (relocation)
Caution:
• Be extremely careful when transporting 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 fins or 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.
• 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.
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 sufficient capacity. Otherwise, a
short circuit, overheating, or fire 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
fire may result.
• 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.
• Do not clean the air conditioner unit with water. Electric shock may result.
• Tighten all flare nuts to specification using a torque wrench. If tightened too
much, the flare 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, lighting 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 specified capacity. If the circuit breaker
capacity is larger than the specified capacity, breakdown or fire 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.
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 specified thickness. (Refer to
page 6) Note the following if reusing existing pipes that carried R22 refrigerant.
- Replace the existing flare nuts and flare the flared sections again.
- Do not use thin pipes. (Refer to page 6)
• 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 flared sections. If mineral oil is mixed in the refrigeration oil, oil
deterioration 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 flowing
refrigerant. If you touch the pipes, burns or frostbite may result.
• After stopping operation, be sure to wait at least five minutes before turning
off the main power switch. Otherwise, water leakage or breakdown 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 specifically designed for use with R410A refrigerant.
The following tools are necessary to use R410A refrigerant. Contact your
nearest dealer for any questions.
• Be sure to use the correct tools. If dust, debris, or moisture enters the refrigerant lines, refrigeration oil deterioration may result.
• Do not use a charging cylinder. If a charging cylinder is used, the composition of the refrigerant will change and the efficiency 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, flow, or accumulate.
• 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 airflow 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 fingers may be pinched.
