» Before
installing the
unit, make
sure you
read
ali the "Safety
precau-
tions".
» Please report to or take consent by the supply authority before connec-
tion to the system.
AN Warning:
Describes
precautions that must
be observed
to prevent danger of injury or
death to the user.
A\ 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
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.
AN Warning:
Carefully read the labels affixed to the main unit.
ZN 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
incorrectiy, water
leak-
age, 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
refrigerant.
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 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 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 appropri-
ate measures to prevent the allowable concentration from being 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 resuit in electric shock or fire.
Be sure to connect the power
supply
cords
and the connecting
wires for
the indoor units, outdoor
units, and
branch
boxes
directly to the units (no
intermediate connections).
Intermediate connections can lead to communication errors if water enters
the cords
or wires and
causes
insufficient insulation to ground
or a poor
electrical contact at the intermediate connection point.
(If an intermediate
connection
is necessary,
be sure to take
measures
to
prevent water from entering the cords and wires.)
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
securely without tension
on the terminals.
If the cables
are connected
or
installed 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
installed, 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 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
&\ 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
significantly reduced and the internal parts can be damaged.
Do
not instali 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
condensation
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)
A\ 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.
