Installation precautions
In addition to heeding the points presented in the "Safety precautions", observe the following
precautions as well.
Concerning the installation location
After conferring in detail with your dealer, choose a sturdy
ceiling or other surface, and install the unit.
Install the unit on a ceiling that is strong enough (such as
a concrete ceiling).
If the unit is to be installed on a ceiling which is not strong
enough, reinforce the ceiling sufficiently first.
Do not install or use the unit in the following kinds of
locations.
On walls (where the unit would be installed sideways)
In locations (including places such as under the eaves of
a building) where the unit would be directly exposed to
rain or water
In locations such as kitchens where there are high
concentrations of steam and grease
In outdoor locations or hot places where the temperature
will exceed 104 °F (40 °C)
In cold locations where the temperature will drop below
3 °F (0 °C)
In locations where the humidity will exceed 85 %
In locations where chemicals are used such as near
swimming pools
At sea, in coastal areas or in locations where corrosive
gases are emitted
In locations where radiation, X-rays, or strong radio
waves or magnetic fields are generated
In locations where the unit would be subject to a great
deal of vibration such as on board a vehicle or ship (this
unit is not designed to be used in vehicles)
In locations where the temperature is subject to sudden
changes such as near the air outlet of an air conditioner
or near a door which allows the outside air to come in
What to avoid to ensure that the unit will perform stably
over a prolonged period
Using the unit for a prolonged period in a location with
high temperature and humidity levels will cause its parts
to deteriorate and shorten its service life.
Do not expose the unit directly to the heat given off in the
installation location or heat from a heater or other such
appliance.
The accessory parts provided with the unit must be
used without fail to install the unit.
Be absolutely sure to use the mounting brackets and
mounting screws provided with the unit to install the unit.
Do not mount the unit by employing any methods other
than those specified.
Do not remodel the installation surface bracket or
mounting screws provided with the unit.
Separately obtain the screws used to mount the
installation surface bracket.
This unit does not come with the screws used to mount the
installation surface bracket.
Obtain the hexagon head bolts (M6), spring washers, flat
washers and, if necessary, nuts.
Tightening the installation screws
Tighten up the screws and bolts to an extent that is
commensurate with the materials and structures in the
installation location.
After tightening up the screws and bolts, visually inspect
for any ricketiness or play, and check that the unit is
secured properly in place.
Use the specified tools and tighten the screws firmly.
When the unit is no longer going to be used, do not
leave it lying around, but be absolutely sure to dispose
of it properly.
For details on how to remove the unit, refer to "Removing
the unit" (page 8).
When installing or disposing of the unit, be absolutely
sure to hold it by its pedestal area.
An accident may occur if its rotating part is held or rotated
by hand.
Do not attach a filter, hood, extender or other parts to
the unit.
Install the unit near the main power outlet, and position
it in such a way that its power plug can be plugged into
and unplugged from the outlet easily.
The provided power cable is for 125 V AC or less.
Another power cable is required for voltage other than
120 V AC.
Do not connect a regular LAN line or telephone line to
the CONTROLLER connector on the unit.
Doing so may cause malfunctioning.
