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.

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 Op-
eration Manual and perform the test run to ensure normal operation. Both the Instal-
lation Manual and Operation Manual must be given to the user for keeping. These
manuals must be passed on to subsequent users.

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.

Contents

 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 incor-
rectly 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.

• 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 loca-

tion.

• After installation has been completed, check for refrigerant leaks. If refriger-

ant 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 in-

stalled 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 explo-
sion 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.

• When the room humidity exceeds 80% or when the drainpipe is clogged, wa-

ter 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-fre-
quency 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 equip-
ment, harming the screen display quality.

• Thermal insulation of the refrigerant pipe is necessary to prevent condensa-

tion. If the refrigerant pipe is not properly insulated, condensation will be formed.

• Place thermal insulation on the pipes to prevent condensation. If the drain-

pipe 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.

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.

• 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.

1. Safety precautions

: Indicates an action that must be avoided.

: Indicates that important instructions must be followed.

: Indicates a part which must be grounded.

: Indicates that caution should be taken with rotating parts.

: Indicates that the main switch must be turned off before servicing.

: Beware of electric shock.

: Beware of hot surface.

ELV

: At servicing, please shut down the power supply for both the Indoor and

Outdoor Unit.

 Warning:

Carefully read the labels affixed to the main unit.

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 dam-
age 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.

• 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.
