Selection of installation location for the indoor unit
2
This indoor unit can be installed either to the floor or to the wall. Select a location with the following
suitable conditions.
j Select the suitable areas to install the unit under approval of the user.
ž Areas where the indoor unit can deliver hot and cold wind sufficiently.
ž Areas where there is enough space to install and service.
ž Areas where it can be drained properly. Areas where drain pipe descending slope can be taken.
ž Areas where there is no obstruction of airflow on both air return grille and air supply port.
ž Areas where fire alarm will not be accidentally activated by the air conditioner.
ž Areas where the supply air does not short-circuit.
ž Areas where it is not influenced by draft air.
ž Areas not exposed to direct sunlight.
ž Areas where dew point is lower than around 23°C and relative humidity is lower than 80%.
This indoor unit is tested under the condition of JIS (Japan Industrial Standard) high humidity
condition and confirmed there is no problem. However, there is some risk of condensation drop
if the air conditioner is operated under the severer condition than mentioned above.
If there is a possibility to use it under such a condition, attach additional insulation of 10 to
20mm thick for entire surface of indoor unit, refrigeration pipe and drain pipe.
ž Areas where TV and radio stays away more than 1m. (It could cause jamming and noise.)
ž Areas where any items which will be damaged by getting wet are not placed such as food, table
wares, server, or medical equipment under the unit.
ž Areas where there is no influence by the heat which cookware generates.
ž Areas where not exposed to oil mist, powder and/or steam directly.
ž Areas where lighting device such as fluorescent light or incandescent light doesn't affect the
operation.
(A beam from lighting device sometimes affects the infrared receiver for the wireless remote
controller and the air conditioner might not work properly.)
k Check if the place where the air conditioner is installed can hold the weight of the unit. If it is not
able to hold, reinforce the structure with boards and beams strong enough to hold it. If the strength
is not enough, it could cause the unit falling down and injury.
l When plural indoor units are installed nearby, keep them away for more than 4 to 5m.
