1. Safety precautions

Before installing the unit, make sure you read all the "Safety
precautions".
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.
1.1. Before installation (Environment)
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 molded case circuit brakers. 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.

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.
• 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.
