CHOOSING A SITE
 Select the signal receiver mounting location according to the following conditions:
• Install the signal receiver, which has a built-in temperature sensor, near the intake vent
where there is convection of air and it can get an accurate reading of the room's temperature.
If the intake vent is in another room or the unit cannot be installed near the intake vent for any
other reason, install it 1.5m above the floor on a wall where there is convection.
• In order to get an accurate reading of the room's temperature, install the
signal receiver in a location where it is not exposed directly to cold or hot air
from the air discharge grille or to direct sunlight.
• Since the receiver has a built-in light receptor to receive signals from the wireless remote
controller, do not mount it in a location where the signal may be blocked by a curtain, etc.
Caution
If the signal receiver is not installed in a location where there is convection of air, it may be unable to get an accurate reading of the room's temperature.
Wireless remote controller
• Turn on all the fluorescent lamps in the room, if any, and find the site where remote controller signals are properly received
by the indoor unit (within 4 metres).
Outdoor unit
• For outdoor unit installation, see the installation manual supplied with the outdoor unit.

PREPARATIONS BEFORE INSTALLATION

 Relation of the unit to the suspension bolt positions.
• Install the inspection opening on the control box side where
maintenance and inspection of the control box are easy. Install
the inspection opening also in the lower part of the unit.
 Make sure the range of the unit's external static
pressure is not exceeded.
(See the technical documentation for the range of the external
static pressure setting.)
 Open the installation hole. (Pre-set ceilings)
• Once the installation hole is opened in the ceiling where the unit
is to be installed, pass refrigerant piping, drain piping,
transmission wiring, and remote controller wiring (unneeded if
using a wireless remote controller) to the unit's piping and
wiring holes.See "REFRIGERANT PIPING WORK", "DRAIN
PIPING WORK", and "WIRING".
• After opening the ceiling hole, make sure ceiling is level if
needed. It might be necessary to reinforce the ceiling frame to
prevent shaking.Consult an architect or carpenter for details.
 Install the suspension bolts.
(Use W3/8 to M10 suspension bolts.)
Use a hole-in-anchor, sunken insert, sunken anchor for existing
ceilings, and a sunken insert, sunken anchor or other part to be
procured in the field to reinforce the ceiling to bearing the weight
of the unit. (Refer to Fig.)
