Cut out the top face cover aligning to the piping

position.

・

When taking pipe out to right-hand side, cut out a

hole along the groove at the inside of side panel.

・

After installing pipes and wires, seal clearances

around pipes and wires with putty, etc. to shut off

dust.

Make sure to install the covers at rear and top in order to

protect the inside of unit from intrusion of dust or

①

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.

・

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 23°C and relative humidity is lower than 80%.
This indoor unit is tested under the condition of JIS (Japan Industrial

However, there is some risk of condensation drop if the air conditioner is
operated 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.

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.)

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

If there are 2 units of wireless type, keep them away for more than 6m to
avoid malfunction due to cross communication.

④

When plural indoor units are installed nearby, keep them away for more than 4 to 5m.

(mm)

Install correctly according to the installation manual.

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.

When both wired and wireless remote control are used

It is necessary to set wired or wireless remote control as slave.

(For the method of changing the setting, refer to the installtion
manual attached to remote control or wireless kit.)

When wired remote control are used only (wireless type)
It is necessary to remove the line that is connected to the receiver.
