(f) Duct connected-High static pressure type (FDU)
(i) Selection of installation location
q Select the suitable areas to install the unit under approval of the user.
• Areas where the indoor unit can deliver hot and cold wind sufficiently. 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 descending slope can be taken.
• Areas where there is no obstruction of airflow on both air return grille and air supply port.
• Areas where fire alarm will not be accidentally activated by the air conditioner.
• Areas where the supply air does not short-circuit.
• Areas where it is not influenced by draft air.
• Areas not exposed to direct sunlight.
• Areas where dew point is lower than around 28ºC 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.
• 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 influence by the heat which cookware generates.
• Areas where not exposed to oil mist, powder and/or steam directly such as above fryer.
• Areas where lighting device such as fluorescent light or incandescent light doesnít 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.)
w 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.
Space for installation and service
● Make installation altitude over 2.5m.
