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 "sweating" on the air discharge ports, causing
them to spray or drip.
●
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
instructions packed with the outdoor unit.
●
allow room for mounting the remote controller about 1 m off
the floor, in an area that is not in direct sunlight nor in the
flow of cool air from the indoor unit.
N OTE
Air delivery will be degraded if the distance from the floor to the
ceiling is greater than 3 m (for D1 type, greater than 3.5 m).

3. HOW TO INSTALL THE INDOOR UNIT

■ 1-Way Cassette Type (D1 Type)

3-1. Preparation for Suspending

This unit uses a drain pump. Use a carpenter ' s level to check
that the unit is level.

3-2. Suspending the Indoor Unit

(1) The measurements of the ceiling hole and suspension bolt
positions should be as shown in Fig. 3-1.
The length of the suspension bolts should extend
a minimum of 15 mm beyond the bottom of the unit
suspension bracket. Refer to Fig. 3-6.
(2) Use the full-scale installation diagram (printed on the
package) to determine the suspension bolt pitch.
The positional relationships between the suspension
brackets and the unit, and between the brackets and the
ceiling panel, should be as shown in Figs. 3-1 & 3-2.

● Use existing ceiling supports or construct a suitable support

WARNING
It is important that you use extreme care in supporting
the indoor unit from the ceiling. Ensure that the ceiling is
strong enough to support the weight of the unit. Before
hanging the unit, test the strength of each attached
suspension bolt.
(4) Cut the ceiling material, if necessary. (Figs. 3-1 and 3-2)
(5) If the system requires fresh air to be drawn into the unit,
cut and remove the insulation (both externally and
internally) at the location shown as A in Fig. 3-5.

3-3. Placing the Unit Inside the Ceiling
(1) When suspending the unit, attach gauges A and B (with
packaging pad) to the indoor unit suspension brackets
using the supplied M5 screws (2 for each bracket) to
create the ceiling opening dimensions.
CAUTION
● Tubing and wiring work will be necessary inside the
ceiling after the unit has been suspended. Therefore,
if the ceiling is already installed, perform tubing and
wiring up to the connection position before suspending
the unit.
(2) Attach the special washers (supplied) and nuts (field
supply) to the suspension bolts (4 locations).
CAUTION
● Use 3/8" or M10 nuts.
● The length of the suspension bolts should be such that
there is clearance of at least 15 mm below the bottom
of the bracket, as shown in Fig. 3-7. If the suspension
bolts are too long, they will contact the ceiling panel and
louver motor cover, making installation impossible.
(3) Thread the 3 hexagonal nuts and 2 washers (field supply)
onto each of the the 4 suspension bolts as shown in Fig.
3-7. 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.
