SAFETY SUMMARY
!Use refrigerant R410A in the refrigerant cycle. Do not charge oxygen, acetylene
!Do not pour water into the indoor or outdoor unit. These products are equipped with
electrical parts. If poured, it will cause a serious electrical shock.
!Do not touch or adjust safety devices inside the indoor or outdoor units. If these
devices are touched or readjusted, it may cause a serious accident.
!Do not open the service cover or access panel for the indoor or outdoor units without
turning OFF the main power supply.
!Refrigerant leakage can cause difficulty with breathing due to insufficient air. Turn OFF
the main switch, extinguish any naked flames and contact your service contractor, if
refrigerant leakage occurs.
!The installer and system specialist shall secure safety against refrigerant leakage
according to local regulations or standards.
!Use an ELB (Electric Leakage Breaker). In the event of a fault, there is danger of an
electric shock or a fire if it is not used.
!Do not install the outdoor unit where there is a high level of oil mist, flammable gases,
salty air or harmful gases such as sulphur.
!Do not use any sprays such as insecticide, lacquer, hair spray or other flammable
gases within approximately one 3.3 ft. (1 meter) from the system.
!If circuit breaker or fuse is often activated, stop the system and contact your service
contractor.
!Do not perform installation work, refrigerant piping work, drain piping and electrical
wiring connection without referring to our installation manual. If the instructions are
not followed, it may result in a water leakage, electric shock or a fire.
!Check that the ground wire is securely connected. If the unit is not correctly grounded,
it may lead to electric shock. Do not connect the ground wiring to gas piping, water
piping, lightning conductor or ground wiring for telephone.
!Connect a fuse of specified capacity.
!Do not put any foreign material on the unit or inside the unit.
!Make sure that the outdoor unit is not covered with snow or ice, before operation.
!Before performing any brazing work, check to ensure that there is no flammable
material around.
When using refrigerant be sure to wear leather gloves to prevent cold injuries.
!Protect the wires, electrical parts, etc. from rats or other small animals.
If not protected, rats may gnaw at unprotected parts which may lead to a fire.
!Fix the cables securely. External forces on the terminals could lead to a fire.
!If the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualified persons in order to avoid a hazard.
!This appliance can be used by children aged from 8 years and above and persons with
reduced physical, sensory or mental capabilities or lack of experience and knowledge if
they have been given supervision or instruction concerning use of the appliance in a
safe way and understand the hazards involved. Children shall not play with the
appliance. Cleaning and user maintenance shall not be done by children without
supervision.
!The appliances are not intended to be operated by means of an external timer or
separate remote-control system.
II

leakage test or an air-tightness test. These types of gases are extremely dangerous
and can cause an explosion. It is recommended that nitrogen be used for these types
oft tests.

4.1 Factory-Supplied Accessories
Check to ensure that the following accessories
are packed with the outdoor unit.
If any of these accessories are not packed with
the unit, please contact your contractor.
Table 4.1 Factory-Supplied Accessories
4.2 Initial Check
•Install the outdoor unit where good ventilation is
available, and where it is dry.
•Install the outdoor unit where the sound or the
discharge air from the outdoor unit does not
affect neighbors or surrounding vegetation.
The operating sound at the rear or right/left
sides is higher than the value in the catalog at
the front side.
•Check to ensure that the foundation is flat, level
and sufficiently strong.
•Do not install the outdoor unit where there is a
high level of oil mist, salty air or harmful gases
such as sulphur.
•Do not install the outdoor unit where the
electromagnetic wave is directly radiated to the
electrical box.
•Install the outdoor unit as far as possible being
at least 0(3 meters) from the
electromagnetic wave radiator.
•When installing the outdoor unit in snow-
covered areas, mount the field-supplied hoods
at the discharge side of the outdoor unit and
the inlet side of the heat exchanger.
•Install the outdoor unit where it is in the shade
or it will not be exposed to direct sunshine or
direct radiation from high temperature heat
source.
•Do not install the outdoor unit where dust or
other contamination could block the outdoor
heat exchanger.
•Install the outdoor unit in a space with limited
access to general public.
NOTE
Washerx4
Direction of Strong Wind
•Do not install the outdoor unit in a space where
a seasonal wind directly blows to the outdoor
heat exchanger or a wind from a building space
directly blows to the outdoor fan.
•Install near the wall to avoid facing wind
directly. Ensure that the service space
should be secured.
A Wall to Guard Against Wind
Wall
Direction of Strong Wind
Aluminum fins have very sharp edges. Pay
attention to the fins to avoid any injury.
NOTE
NOTE:
If the extreme strong wind blows directly against
the air discharge portion, the fan may rotate
reversely and be damaged.
Install the outdoor unit on a roof or in an area
where people except service engineers can not
touch the outdoor unit.
