1. Safety precautions
Please report to or take consent by the supply authority before connection
to the system.
Be sure to read "The following should always be observed for safety" before
installing the air conditioner.
Be sure to observe the cautions specified here as they include important
items related to safety.
• The indications and meanings are as follows.
/_ Warning:
Could lead to death, serious injury, etc.
Z_ Caution:
Could lead to serious injury in particular environments when operated incor-
rectly.
After reading this manual, be sure to keep it together with the instruction
manual in a handy place on the customer's site.
z_ Warning:
• Do not install it by yourself (customer).
Incomplete installation could cause injury due to fire, electric shock, the unit
falling or leakage of water. Consult the dealer from whom you purchased the
unit or special installer.
• Install the unit securely in a place which can bear the weight of the unit.
When installed in an insufficient strong place, the unit could fall causing in-
jured.
• Use the specified wires to connect the indoor and outdoor units securely and
attach the wires firmly to the terminal board connecting sections so the stress
of the wires is not applied to the sections.
Incomplete connecting and fixing could cause fire.
• 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.
• Check that the refrigerant gas does not leak after installation has completed.

This Installation Manual only applies to the indoor unit and the SUZ series out-
door unit.
If the outdoor unit is MXZ series, refer to the Installation Manual for MXZ series.
Symbols put on the unit
: Indicates an action that must be avoided.
O: Indicates that important instructions must be followed.
O : Indicates a part which must be grounded.
z_: Indicates that caution should be taken with rotating parts.
: Indicates that the main switch must be turned off before servicing.
Z_ : Beware of electric shock.
z_ : Beware of hot surface.
Z_ Warning:
Carefully read the labels affixed to the main unit.
• Perform the installation securely referring to the installation manual.
Incomplete installation could cause a personal injury due to fire, electric shock,
the unit falling or leakage of water.
• Perform electrical work according to the installation manual and be sure to
use an exclusive circuit.
If the capacity of the power circuit is insufficient or there is incomplete elec-
trical work, it could result in a fire or an electric shock.
• Attach the electrical part cover to the indoor unit and the service panel to the
outdoor unit securely.
If the electrical part cover in the indoor unit and/or the service panel in the
outdoor unit are not attached securely, it could result in a fire or an electric
shock due to dust, water, etc.
• Be sure to use the part 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.
• Ventilate the room if refrigerant leaks during operation.
If the refrigerant comes in contact with a flame, poisonous gases will be re-
leased.
/_, Caution:
• Ground the unit.
Do not connect the ground wire to a gas pipe, water pipe arrester or telephone
ground wire. Defective grounding could cause an electric shock.
• Do not install the unit in a place where an inflammable gas leaks.
If gas leaks and accumulates in the area surrounding the unit, it could cause
an explosion.
• Install a ground leakage breaker depending on the installation place (where it
is humid).
If a ground leakage breaker is not installed, it could cause an electric shock.
2. Selecting the installation location
2.1. Indoor unit
• Where airflow is not blocked.
• Where cool air spreads over the entire room.
• Where it is not exposed to direct sunshine.
• At a distance 1 m [39-3/8 in] or more away from aTV and radio (to prevent picture
from being distorted or sound from being generated).
• In a place as far away as possible from fluorescent and incandescent lights (so the
infrared remote control can operate the air conditioner normally).
2.2. Outdoor unit
• Where it is not exposed to strong wind.
• Where airflow is good and dustless.
• Where it is not exposed to rain and direct sunshine.
• Where neighbours are not annoyed by operation sound or hot air.
• Where rigid wall or support is available to prevent the increase of operation sound
or vibration.
• Where there is no risk of combustible gas leakage.
• When installing the unit at a high level, be sure to fix the unit legs.
• Where it is at least 3m [10 ft] away from the antenna of TV set or radio. (Otherwise,
images would be disturbed or noise would be generated.)
• Perform the drainage/piping work securely according to the installation
manual,
If there is a defect in the drainage/piping work, water could drop from the unit
and household goods could be wet and damaged,
• Fasten a flare nut with a torque wrench as specified in this manual,
When fastened too tight, a flare nut may broken after a long period and cause
a leakage of refrigerant,
• Where the air filter can be removed and replaced easily.
Warning:
Mount the indoor unit into a ceiling strong enough to withstand the weight of
the unit.
• Install the unit horizontally.
Z_ Caution:
Avoid the following places for installation where air conditioner trouble is li-
able to occur.
• Where there is too much machine oil in the air.
• Salty environments as seaside areas.
• Hot-spring areas.
• Where sulfide gas exists.
• Other special atmospheric areas.
