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 specically made for use with refrigerant
specied in the outdoor unit installation manual.
• 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 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 ame, poisonous gases will be released.
• All electric work must be performed by a qualied technician according to
local regulations and the instructions given in this manual.
• Use only specied cables for wiring.
• The terminal block cover panel of the unit must be rmly 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 refrig-
erant leaks into the room and comes into contact with the ame of a heater
or portable cooking range, poisonous gases will be released.
1.1. Before installation (Environment)
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 sulfu-
ric gas, areas exposed to high salt content such as the seaside, the perform-
ance can be signicantly reduced and the internal parts can be damaged.
• Do not install the unit where combustible gases may leak, be produced,
ow, or accumulate. If combustible gas accumulates around the unit, re
or explosion may result.
• Do not keep food, plants, caged pets, artwork, or precision instruments in
the direct airow 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,
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 ofce, be pre-
pared 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 con-
ditioner may also affect medical equipment, disturbing medical care, and
communications equipment, harming the screen display quality.
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 ns 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.
•
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, oor,
furniture, or other possessions may result.
• Do not clean the air conditioner unit with water. Electric shock may result.
• Tighten all are nuts to specication using a torque wrench. If tightened
too much, the are 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 sufcient capacity. Otherwise,
a short circuit, overheating, or re 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 specied capacity. If the circuit breaker
capacity is larger than the specied capacity, breakdown or re may result.
1.4. Before starting the test run
Caution:
• Turn on the main power switch more than 12 hours before starting opera-
tion. 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 protec-
tive parts are correctly installed. Rotating, hot, or high voltage parts can
cause injuries.
• Do not operate the air conditioner without the air lter set in place. If the air
lter 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 ve minutes before turning
off the main power switch. Otherwise, water leakage or breakdown may result.
