1.5.1 Installation of indoor unit
(1)
Ceiling recessed compact type (FDTC)
(a) Selection of installation location
1) Select location where the space above ceiling is larger than those mentioned below and perfect draining can be assured.
2) With the customer’s consent, select a location with following suitable conditions.
a) Where cool air or hot air can easily pass through.
If the height of the location exceeds 3 m, hot air will gather in the ceiling. Suggest to the customer to also install a circula-
tor.
b) Where water can be completely drained. A sloping location for drainage.
c) Where there are no wind disturbances to the suction inlet and blowing outlet, where the fi re alarm will not be set off er-
roneosly, where no short circuits occur.
d) Where there is no direct sunlight.
e) Please with the environmental dew-point temperature is lower than 28ºC and the relative humidity is less than 80%.
This unit is tested under ISO installation conditions to make sure that there are no defects. However, if it is
operated under conditions of high humidity that exceed the conditions above, there is danger of condensate
falling from the unit. If there is a possibility that the unit will be used under such conditions, dress 10~20 mm
of insulation on the entire unit body, the piping and drain pipe.
3) Consider the supporting strength of the location. If the strength is not suffi cient to sustain the unit weight, use reinforcing
materials.
(b) Installation space for unit
a) When
a
suffi cient interval cannot be secured between the unit and a wall or
another unit, shut up diffusers on that side to block winds and make sure that
no short-circuiting is occurring. (A wind blocking material is available as an
optional part)
• Do not use the unit in the “Lo” wind mode, when winds are blown into two
or three directions.
