② Selection of installation location for the indoor unit
➀ Select the suitable areas to install the unit under approval of the user.
・
Suggest to the user to use a circulator if the ceiling height is over 3m to
avoid warm air being accumulated on the ceiling.
・In case of having the motion sensor, the installation height must be no higher than
4 m. It could reduce the sensitivity of motion sensor, disabling the detection.
・Areas where there is enough space to install and service.
・Areas where it can be drained properly. Areas where drain pipe descend-
ing slope can be taken.
・
・
・Areas where the supply air does not short-circuit.
・
・Areas not exposed to direct sunlight.
・Areas where dew point is lower than around 28°C and relative humidity is lower than 80%.
This indoor unit is tested under the condition of JIS (Japan Industrial Standard) high
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.
・Areas where TV and radio stays away more than 1m. (It could cause jamming and noise.)
・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.
・
・Areas where not exposed to oil mist, powder and/or steam directly such as above fryer.
・
doesn't affect the operation.
(A beam from lighting device sometimes affects the infrared receiver for the
wireless remote control and the air-conditioner might not work properly.)
➁ 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 injury due to unit falling.
➂ If there are 2 units of wireless type, keep them away for more than 6m to avoid
malfunction due to cross communication.
➃ When plural indoor units are installed nearby, it is recommended to separate each
other more than 4m.

③ Preparation before installation
If suspension bolt becomes longer, do reinforcement of earthquake resistant.
For grid ceiling
When suspension bolt length is over 500mm, or the gap between the ceiling
and roof is over 700mm, apply earthquake resistant brace to the bolt.
In case the unit is hanged directly from the slab and is installed on the
ceiling plane which has enough strength.
When suspension bolt length is over 1000mm, apply the earthquake resistant brace to the bolt.
Prepare four (4) sets of suspension bolt, nut and spring washer (M10) on site.

room from outside, which could result in fire
or other hazards.
Work procedure
1. Select the suspension bolt locations and the pipe hole location.
(1) Use enclosed paper pattern as a reference, and
drill the holes for the suspension bolts and pipe.
Decide the locations based on direct measurements.
※
(2) Once the locations are properly placed, the paper
pattern can be removed.
2. Install the suspension bolts in place.
3. Fix with 4 suspension bolts.
