Preparation before installation
ԙ
Selection of installation location for the indoor unit
Ԙ
Select the suitable areas to install the unit under approval of the user.
ޓ
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 28°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.
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 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.)
ԙ
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
٨
Make installation altitude over 2.5m.
(Indoor Unit)
Select either of two cases to keep space for installation and services.
Notes (a) There must not be obstacle to draw out fan motor. ( marked area)
(b) Install refrigerant pipe, drain pipe, and wiring so as not to cross marked area.
٨
If suspension bolt becomes longer, do reinforcement of earthquake resistant.
ޓ٤
For grid ceiling
ޓޓ
When the suspension bolt length is over 500mm, or the gap between the ceiling and roof is
over 700mm, apply earthquake resistant brace to the bolt.
ޓ٤
In case the unit is hanged directly from the slab and is installed on the ceiling plane which
has enough strength.
ޓޓ
When suspension bolt length is over 1000mm, apply the earthquake resistant brace to the bolt.
٨
Prepare four (4) sets of suspension bolt, nut and spring washer (M10) on site.
٤
This model is middle static ducted type air conditioning unit. Therefore, do not use this model for direct
blow type air conditioning unit.
