11.1 Select the Best Location
INDOOR UNIT
There should not be any heat source or steam
near the unit.
A place where air circulation in the room is good.
A place where drainage can be easily done.
A place where noise prevention is taken into
consideration.
Do not install the unit near the door way.
Ensure the spaces indicated by arrows from the
wall, ceiling, fence or other obstacles.
Recommended installation height for indoor unit
shall be at least 800 mm.
Must install on a vertical wall.
When install electrical equipment at wooden
building of metal lath or wire lath, according to
electrical facility technical standard, no electrical
contact between equipment and building is
allowed. Insulator must be installed in between.

contact between equipment and building is
allowed. Insulator must be installed in between.
Do not install the unit at outdoor. This is designed
for indoor installation only.
When connecting solar pump station cable
between indoor unit and solar pump station, the
distance between both apparatuses shall be 2 ~ 8
meters and the maximum length of 10 meter only.
Failure to do so may lead to abnormal operation
to the system.

OUTDOOR UNIT
If an awning is built over the unit to prevent direct
sunlight or rain, be careful that heat radiation from
the condenser is not obstructed.
the condenser is not obstructed.
Avoid installations in areas where the ambient
temperature may drop below -20°C.
Keep the spaces indicated by arrows from wall,
ceiling, fence or other obstacles.
Do not place any obstacles which may cause a
short circuit of the discharged air.
If outdoor unit installed near sea, region with high
content of sulphur or oily location (e.g. machinery
oil, etc), it lifespan maybe shorten.

When installing the product in a place where it will
be affected by typhoon or strong wind such as
wind blowing between buildings, including the
rooftop of a building and a place where there is no
building in surroundings, fix the product with an
overturn prevention wire, etc. (Overturn prevention
fitting model number: K-KYZP15C)
