1. BEFORE INSTALLATION
1-1. THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY
• Be sure to read "THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY" before installing the air conditioner.
• Be sure to observe the warnings and cautions specified here as they include important items related to safety.
• After reading this manual, be sure to keep it together with the OPERATING INSTRUCTIONS for future reference.
n Do not install the unit by yourself (user).
Incomplete installation could cause fire, electric
shock, injury due to the unit falling, or leakage
of water. Consult the dealer from whom you pur-
chased the unit or a qualified installer.
n Perform the installation securely referring to
the installation manual.
Incomplete installation could cause fire, electric
shock, injury due to the unit falling, or leakage of
water.
n When installing the unit, use appropriate pro-
tective equipment and tools for safety.
Failure to do so could cause injury.
n Install the unit securely in a place which can
bear the weight of the unit.
If the installation location cannot bear the weight
of the unit, the unit could fall causing injury.
n Electrical work should be performed by a
qualified, experienced electrician, according
to the installation manual. Be sure to use an ex-
clusive circuit. Do not connect other electrical
appliances to the circuit.
If the capacity of the power circuit is insufficient or
there is incomplete electrical work, it could result
in a fire or an electric shock.
n Earth the unit correctly.
Do not connect the earth to a gas pipe, water
pipe, lightning rod or telephone earth. Defective
earthing could cause electric shock.
n Do not damage the wires by applying exces-
sive pressure with parts or screws.
Damaged wires could cause fire or electric shock.
n Be sure to cut off the main power in case of
setting up the indoor P.C. board or wiring
works.
Failure to do so could cause electric shock.
n Use the specified wires to connect the indoor
and outdoor units securely and attach the
wires firmly to the terminal block connecting
sections so the stress of the wires is not ap-
plied to the sections. Do not extend the wires,
or use intermediate connection.
Incomplete connecting and securing could cause
fire.
n I nstall an earth leakage breaker depending on
the installation place.
If an earth leakage breaker is not installed, it
could cause electric shock.
1-2. SELECTING THE INSTALLATION LOCATION
INDOOR UNIT
• Where airflow is not blocked.
• Where cool air spreads over the entire room.
• Rigid wall without vibration.
• Where it is not exposed to direct sunshine. Do not
expose to direct sunshine also during the period
following unpacking to before use.
• Where easily drained.
• At a distance 1 m or more away from your TV and
radio. Operation of the air conditioner may interfere
with radio or TV reception. An amplifier may be
required for the affected device.
• In a place as far away as possible from fluorescent
and incandescent lights (so the infrared remote
control can operate the air conditioner normally).
• Where the air filter can be removed and replaced
easily.
En-
This installation manual de-
scribes only for the indoor unit.
Refer to the MXZ type manual for
outdoor unit set up.
WARNING
n Do not install the unit in a place where inflam-
mable gas may leak.
If gas leaks and accumulates in the area around
the unit, it could cause an explosion.
n Do not use intermediate connection of the
power cord or the extension cord and do not
connect many devices to one AC outlet.
It could cause a fire or an electric shock due to
defective contact, defective insulation, exceeding
the permissible current, etc.
n Be sure to use the parts provided or specified
parts for the installation work.
The use of defective parts could cause an injury or
leakage of water due to a fire, an electric shock, the
unit falling, etc.
n When plugging the power supply plug into the
outlet, make sure that there is no dust, clogging,
or loose parts in both the outlet and the plug.
Make sure that the power supply plug is pushed
completely into the outlet.
If there is dust, clogging, or loose parts on the power
supply plug or the outlet, it could cause electric
shock or fire. If loose parts are found on the power
supply plug, replace it.
n Attach the electrical cover to the indoor unit
and the service panel to the outdoor unit
securely.
If the electrical cover of the indoor unit and/or the
service panel of the outdoor unit are not attached
securely, it could result in a fire or an electric shock
due to dust, water, etc.
n When installing, relocating, or servicing the
unit, make sure that no substance other than
the specified refrigerant (R410A) enters the
refrigerant circuit.
Any presence of foreign substance such as air
can cause abnormal pressure rise and may result
in explosion or injury. The use of any refrigerant
other than that specified for the system will cause
mechanical failure, system malfunction, or unit
breakdown. In the worst case, this could lead to a
serious impediment to securing product safety.
CAUTION
n Perform the drainage/piping work securely ac-
cording to the installation manual.
If there is defect in the drainage/piping work, wa-
ter could drop from the unit, soaking and damag-
ing household goods.
n Do not touch the air inlet or the aluminum fins
of the outdoor unit.
This could cause injury.
REMOTE CONTROLLER
• Where it is easy to operate and easily visible.
• Where children cannot touch it.
• Select a position about 1.2 m above the floor and
check that signals from the remote controller are
surely received by the indoor unit from that posi-
tion ('beep' or 'beep beep' receiving tone sounds).
After that, attach remote controller holder to a pillar
or wall and install wireless remote controller.
Note:
In rooms where inverter type fluorescent lamps are
used, the signal from the wireless remote controller
may not be received.
Required Tools for Installation
Phillips screwdriver
Level
Scale
Utility knife or scissors
65 mm hole saw
Torque wrench
Wrench (or spanner)
(Could lead to death, serious injury, etc.)
n Do not discharge the refrigerant into the atmos-
phere. If refrigerant leaks during installation,
ventilate the room.
If refrigerant comes in contact with a fire, harmful
gas could be generated. Refrigerant leakage may
cause suffocation. Provide ventilation in accord-
ance with EN378-1.
n Check that the refrigerant gas does not leak
after installation has been completed.
If refrigerant gas leaks indoors, and comes into
contact with the flame of a fan heater, space
heater, stove, etc., harmful substances will be
generated.
n Use appropriate tools and piping materials for
installation.
The pressure of R410A is 1.6 times more than
R22. Not using appropriate tools or materials and
incomplete installation could cause the pipes to
burst or injury.
n When pumping down the refrigerant, stop the
compressor before disconnecting the refriger-
ant pipes.
If the refrigerant pipes are disconnected while the
compressor is running and the stop valve is open,
air could be drawn in and the pressure in the re-
frigeration cycle could become abnormally high.
This could cause the pipes to burst or injury.
n When installing the unit, securely connect the
refrigerant pipes before starting the compres-
sor.
If the compressor is started before the refrigerant
pipes are connected and when the stop valve is
open, air could be drawn in and the pressure in
the refrigeration cycle could become abnormally
high. This could cause the pipes to burst or injury.
n Fasten a flare nut with a torque wrench as
specified in this manual.
If fastened too tight, a flare nut may break after a
long period and cause refrigerant leakage.
n The unit shall be installed in accordance with
national wiring regulations.
(Could lead to serious injury in particular environments when operated incorrectly.)
n Do not install the outdoor unit where small
animals may live.
If small animals enter and touch the electric parts
inside the unit, it could cause a malfunction,
smoke emission, or fire. Also, advise user to keep
the area around the unit clean.
Note:
Avoid the following places for installation where air
conditioner trouble is liable to occur.
• Where flammable gas could leak.
• Where there is much machine oil.
• Where oil is splashed or where the area is filled
with oily smoke (such as cooking areas and fac-
tories, in which the properties of plastic could be
changed and damaged).
• Salty places such as the seaside.
• Where sulfide gas is generated such as a hot
spring.
• Where there is high-frequency or wireless equip-
ment.
• Where there is emission of high levels of VOCs,
including phthalate compounds, formaldehyde,
etc., which may cause chemical cracking.
