NOTICE

The  equipment  described  in  this  manual  may  cause
electronic  noise  generated  from  radio-frequency  energy.
The  equipment  complies  to  specifications  that  are
designed  to  provide  reasonable  protection  against  such
interference.  However,  there  is  no  guarantee  that
interference will not occur in a particular installation.

It  is  therefore  recommended  to  install  the  equipment  and
electric  wires  keeping  proper  distances  away  from  stereo
equipment, personal computers, etc.

In  places  with  weak  reception,  keep  distances  of  3  m  or  more  to
avoid  electromagnetic  disturbance  of  other  equipment  and  use
conduit tubes for power and transmission lines.

▪ Select a place where rain can be avoided as much as possible.

▪ Take  care  that  in  the  event  of  a  water  leak,  water  cannot  cause

any damage to the installation space and surroundings.

▪ Choose a location where the hot/cold air discharged from the unit

or the operation noise, will NOT disturb anyone.

▪ Heat  exchanger  fins  are  sharp  and  injury  is  possible.  Choose  an

installation  location  where  there  is  no  risk  for  injury  (especially  in
areas where children play).

Do NOT install the unit in the following places:

▪ Sound  sensitive  areas  (e.g.  near  a  bedroom),  so  that  the

operation noise will cause no trouble.
Note:  If  the  sound  is  measured  under  actual  installation
conditions,  the  measured  value  might  be  higher  than  the  sound
pressure level mentioned in Sound spectrum in the data book due
to environmental noise and sound reflections.

INFORMATION

The sound pressure level is less than 70 dBA.

▪ In  places  where  a  mineral  oil  mist,  spray  or  vapour  may  be

present  in  the  atmosphere.  Plastic  parts  may  deteriorate  and  fall
off or cause water leakage.

It  is  NOT  recommended  to  install  the  unit  in  the  following  places
because it may shorten the life of the unit:

▪ Where the voltage fluctuates a lot

▪ In vehicles or vessels

▪ Where acidic or alkaline vapour is present

Seaside  installation.

  Make  sure  the  outdoor  unit  is  NOT  directly

exposed  to  sea  winds.  This  is  to  prevent  corrosion  caused  by  high
levels of salt in the air, which might shorten the life of the unit.

Install the outdoor unit away from direct sea winds.

Example: 

Behind the building.

If the outdoor unit is exposed to direct sea winds, install a
windbreaker.

▪ Height of windbreaker≥1.5×height of outdoor unit

▪ Mind  the  service  space  requirements  when  installing  the

windbreaker.

Strong winds (≥18 km/h) blowing against the outdoor unit’s air outlet
causes short circuit (suction of discharge air). This may result in:

▪ deterioration of the operational capacity;

▪ frequent frost acceleration in heating operation;

▪ disruption  of  operation  due  to  decrease  of  low  pressure  or

increase of high pressure;

▪ a  broken  fan  (if  a  strong  wind  blows  continuously  on  the  fan,  it

may start rotating very fast, until it breaks).

It  is  recommended  to  install  a  baffle  plate  when  the  air  outlet  is
exposed to wind.

It is recommended to install the outdoor unit with the air inlet facing
the wall and NOT directly exposed to the wind.
