use,and maintenance
of the unit to the customer according to the information
in the

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
re-
frigerant.
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 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 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
be-
ing 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.
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
cor-
rectly, the unit will not be properly
grounded
and electric
shock
may result.
• Use only
specified
cables
for wiring.
The connections
must
be made se-
curely
without
tension
on the terminals.
If the cables
are connected
or in-
stalled
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
refrig-
erant
(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
in-
stalled,
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 refrig-
erant 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
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 sig-
nificantly 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 condensa-
tion is likely to 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 communi-
cations
equipment,
harming
the screen
display
quality.
1.2. Before installation (relocation)
Caution:
• Be extremely
careful
when transporting
the units. 2 or more persons
are
needed to handle the unit, as it weighs
20 kg, 44 Ibs 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 the
edge of 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.
• 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.
