②Selection of installation location for the indoor unit
① Select the suitable areas to install the unit under approval of the user.
・Areas where the indoor unit can deliver hot and cold wind suf ciently.
Suggest to the user to use a circulator if the ceiling height is over 3m to
avoid warm air being accumulated on the ceiling.
・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 there is no obstruction of air ow on both air return grille and air supply port.
・Areas where re alarm will not be accidentally activated by the air-conditioner.
・Areas where the supply air does not short-circuit.
・Areas where it is not in uenced by draft air.
・Areas not exposed to direct sunlight.
・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 Stan-
dard) high humidity condition and con rmed there is no problem. How-
ever, there is some risk of condensation drop if the air-conditioner is oper-
ated under the severer condition than mentioned above.
・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 there is no in uence by the heat which cookware generates.
・Areas where not exposed to oil mist, powder and/or steam directly such as above fryer.
② 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.
③ When plural indoor units are installed nearby, keep them away for more than 4 to 5m.

③Preparation 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.

④Installation of indoor unit
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, which can endure load of 500N.
4. Check the measurements given at the right
gure for the length of the suspension bolts.
5. Fasten the hanging plate onto the suspension bolts.
