2. SELECTING THE INSTALLATION SITE

2-1. Indoor Unit
AVOID:
● areas where leakage of flammable gas may be expected.
● places where large amounts of oil mist exist.
● direct sunlight.
● locations near heat sources which may affect the
performance of the unit.
● locations where external air may enter the room directly.
This may cause "condensation" on the air discharge ports,
causing them to spray or drip water.
● locations where the remote controller will be splashed with
water or affected by dampness or humidity.
● installing the remote controller behind curtains or furniture.
● locations where high-frequency emissions are generated.
DO:
● select an appropriate position from which every corner of the
room can be uniformly cooled.
● select a location where the ceiling is strong enough to
support the weight of the unit.
● select a location where tubing and drain pipe have the
shortest run to the outdoor unit.
● allow room for operation and maintenance as well as
unrestricted air flow around the unit.
● install the unit within the maximum elevation difference
above or below the outdoor unit and within a total tubing
length (L) from the outdoor unit as detailed in the installation
manual packed with the outdoor unit.
● allow room for mounting the remote controller about 1m off
the floor, in an area that is not in direct sunlight or in the flow
of cool air from the indoor unit.

3-1. Preparation for Ceiling Suspension
This unit uses a drain pump. Use a carpenter's level to check
that the unit is level.
3-2. Mounting the Suspension Bolts
(1) Fix the suspension bolts securely to the ceiling using the
method shown in the diagrams (Figs. 3-1 and 3-2), by
attaching them to the ceiling support structure, or by any
other method that ensures that the unit will be securely and
safely suspended.
(2) Follow the diagram to make the holes in the ceiling. (Refer
to Fig. 3-2)

(3) Determine the pitch of the suspension bolts using the
supplied full-scale installation diagram. The diagram shows
the relationship between the positions of the suspension
fitting, the unit, and the panel.

(1) When placing the unit inside the ceiling, determine the

pitch of the suspension bolts using the supplied full-scale
installation diagram. (Fig. 3-4)

Tubing and wiring must be laid inside the ceiling when
suspending the unit. If the ceiling is already constructed, lay
the tubing and wiring into position for connection to the unit
before placing the unit inside the ceiling.
(2) The length of suspension bolts must be appropriate for a
distance between the bottom of the bolt and the bottom of
the unit of more than 15 mm. (Fig. 3-4)

(3) Thread the 3 hexagonal nuts and 2 washers (field supply)
onto each of the 4 suspension bolts (Fig. 3-5). Use 1 nut
and 1 washer for the upper side, and 2 nuts and 1 washer
for the lower side, so that the unit will not fall off the
suspension lugs.

(4) Adjust so that the distance between the unit and the ceiling
bottom is 13 to 18 mm. Tighten the nuts on the upper side
and lower side of the suspension lug.
(5) Remove the protective polyethylene used to protect the fan
parts during transport.
