1. Safety precautions

s Before installing the unit, make sure you read all the “Safety precau-

tions”.

s Please report to your supply authority or obtain their consent before

connecting this equipment to the power supply 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:

• Ask a dealer or an authorized technician to install the unit.

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

tools and pipe components specifically made for use with refrigerant specified
in the outdoor unit installation manual.

• 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 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. Should the refrigerant leak and cause
the concentration limit to be exceeded, hazards due to lack of oxygen in the
room may result.

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.

• 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.

• Use only specified cables for wiring.

• The terminal block cover panel of the unit must be firmly attached.

• Use only accessories authorized by Mitsubishi Electric and ask a dealer or
an authorized technician to install them.

• The user should never attempt to repair the unit or transfer it to another loca­tion.

• 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.

1.1. Before installation (Euvironment)

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, 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.

• Do not keep food, plants, caged pets, artwork, or precision instruments in the
direct airflow of the indoor unit or too close to the unit, as these items can be
damaged by temperature changes or dripping water.

1.2. Before installation or 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 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.

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.

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.

• Before starting operation, check that all panels, guards and other protective
parts are correctly installed. Rotating, hot, or high voltage parts can cause
injuries.

• When the room humidity exceeds 80% or when the drainpipe is clogged, wa­ter may drip from the indoor unit. Do not install the indoor unit where such
dripping can 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.

• Thermal insulation of the refrigerant pipe is necessary to prevent condensa­tion. If the refrigerant pipe is not properly insulated, condensation will be formed.

• Place thermal insulation on the pipes to prevent condensation. If the drain­pipe is installed incorrectly, water leakage and damage to the ceiling, floor,
furniture, or other possessions may result.

• 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.

• Be sure to ground the unit. 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.

• Do not operate the air conditioner without the air filter set in place. If the air
filter is not installed, dust may accumulate and breakdown may result.

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

• Do not touch the refrigerant pipes with bare hands during operation.

• 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.

4. Installing the refrigerant piping

4.1. Precautions

4.1.1. For devices that use R407C refrigerant

• Do not use the existing refrigerant piping.

• Do not use crushed, misshapen, or discolored tubing. The inside of the tub­ing should be clean and free from harmful sulfuric compounds, oxidants,
dirt, debris, oils and moisture.

• Store the piping to be used during installation indoors and keep both ends of
the piping sealed until just before brazing.

• Use ester oil, ether oil or alkylbenzene (small amount) as the refrigerator oil
to coat flares and flange connections.

• Use liquid refrigerant to fill the system.

• Do not use a refrigerant other than R407C.

• Use a vacuum pump with a reverse flow check valve.

• Do not use the tools that are used with conventional refrigerants.

• Do not use a charging cylinder.

• Be especially careful when managing the tools.

• Do not use commercially available dryers.

4.1.2. For devices that use R410A refrigerant

• Use ester oil, ether oil, alkylbenzene oil (small amount) as the refrigeration oil
applied to the flared sections.

• Use C1220 copper phosphorus, for copper and copper alloy seamless pipes,
to connect the refrigerant pipes. Use refrigerant pipes with the thicknesses
specified in the table to the below. Make sure the insides of the pipes are
clean and do not contain any harmful contaminants such as sulfuric com­pounds, oxidants, debris, or dust.

Warning:
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.
