 Incomplete  installation  could  cause  fire,  electric

shock,  injury  due  to  the  unit  falling,  or  leakage  of

 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.

 The use of defective parts could cause an injury or

leakage of water due to a fire, an electric shock, the unit

falling, etc.

 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 

 If the electrical cover of the indoor unit and/or the serv-

ice 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, 

 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  me-

chanical failure, system malfunction, or unit break-

down. In the worst case, this could lead to a serious

impediment to securing product safety.

n  Do not discharge the refrigerant into the atmos-

 If  refrigerant  comes  in  contact  with  a  fire,  harmful

gas could be generated.

n  Check that the refrigerant gas does not leak 

 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 

 The pressure of R410A is 1.6 times more than R22.

Not using appropriate tools or materials and incom-

plete  installation  could  cause  the  pipes  to  burst  or

injury.

n  When pumping down the refrigerant, stop the 

 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 refrig-

eration  cycle  could  become  abnormally  high.  This

could cause the pipes to burst or injury.

n  When installing the unit, securely connect the 

 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.

 If  fastened  too  tight,  a  flare  nut  may  break  after  a

long period and cause refrigerant leakage.

cause electric shock.

 If there is defect in the drainage/piping work, water

could  drop  from  the  unit,  soaking  and  damaging

household goods.

 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.

(Could lead to death, serious injury, etc.)

•  Where airflow is not blocked.

•  Where 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 fol-

lowing 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  re-

quired for the affected device.

•  In a place as far away as possible from fluorescent

and incandescentlights.

    

In order to make the infrared remote control operate the air-

conditioner normally. The heat from the lights may cause

deformation or the ultraviolet may cause deterioration.

•  Where the air filter can be removed and replaced easily.

•  Where it is easy to operate and easily visible.

•  Where children cannot touch it.

•  Select the position where the indoor unit can receive

the signal from the remote controller properly. Check

that signals from the remote controller are surely re-

ceived by the indoor unit from that position (‘beep’ or

‘beep beep’ receiving tone sounds). After that, attach

remote controller holder to a pillar or wall and install

wireless remote controller.

In  rooms  where  inverter  type  fluorescent  lamps  are

used, the signal from the wireless remote controller may

not be received.

•  Where it is not exposed to strong wind.

•  Where airflow is good and dustless.

•  Where rain or direct sunlight can be avoided as much

as possible.

•  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

secure the unit legs.

•  Where it is at least 3 m away from the antenna of

TV set or radio. Operation of the air conditioner may

interfere with radio or TV reception in areas where re-

ception is weak. An amplifier may be required for the

affected device.

•  Install the unit horizontally.

•  Please install it in an area not affected by snowfall or

blowing snow. In areas with heavy snow, please in-

stall a canopy, a pedestal and/or some baffle boards.

It is advisable to make a piping loop near outdoor unit

so as to reduce vibration transmitted from there.

When operating the air conditioner in low outside tem-

perature, be sure to follow the instructions described

below.

•  Never  install  the  outdoor  unit  in  a  place  where

its air inlet/outlet side may be exposed directly to

wind.

•  To  prevent  exposure  to  wind,  install  the  outdoor

unit with its air inlet side facing the wall.

•  To prevent exposure to wind, it is recommended

to install a baffle board on the air outlet side of the

outdoor unit.

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.

When installing multi units, refer to

the installation manual of the multi

unit for outdoor unit installation.
