3-2. Suspending the Indoor Unit

Depending on the ceiling type:
●
Insert suspension bolts as shown in Fig. 3-3
or
Hole-in-anchor
Concrete Insert
Hole-in-plug
Suspension bolt (M10 or 3/8")
(field supply)
Fig. 3-3
●
Use existing ceiling supports or construct a suitable support
as shown in Fig. 3-4.

WARNING
It is important that you use extreme care in supporting the
indoor unit inside 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.
(1) When placing the unit inside the ceiling, determine the pitch
of the suspension bolts referring to the dimensional data
given previously.
(Figs. 3-1 and 3-2)
Tubing must be laid and connected inside the ceiling when
suspending the unit. If the ceiling is already constructed,
lay the tubing into position for connection to the unit before
placing the unit inside the ceiling.
(2) Screw in the suspension bolts allowing them to protrude
from the ceiling as shown in Fig. 3-3.
(Cut the ceiling material, if necessary.)
(3) Suspend and fix the indoor unit using the 2 hexagonal nuts
(field supply) and special washers (supplied with the unit)
as shown in Fig. 3-5.

3-3. Installing the Refrigerant Tubing

The size of the refrigerant tubing is as shown in Table 3-1.

Liquid tube ø9.52 ø12.7

● When brazing the gas tubing, cool the tubing with dampened
shopcloths as you work, as shown in Fig. 3-6, to protect the
unit's thermistor from the heat generated by brazing.

The tube connector that comes with the Type 10 indoor unit
cannot be used in combination with this outdoor unit.
Use in combination with the U-250PE1E8.
●
The type 8 indoor unit comes with a tube connector that is
for liquid tubing. Configure as shown in the illustration and
connect it.
When flaring the tube, put the flare nut onto it first and then
flare it.
Remove the ø 12.7 flare
nut from the liquid tubing of
the indoor unit and use it.

●
Be sure to insulate both the gas tubing and liquid tubing. In
addition, wrap the supplied insulation material around the
tubing joints, and fasten in place with vinyl tape or other
means. Failure to insulate the tubing may result in water
leakage from condensation.
●
Plug all gaps at tube through-holes in the unit with insulation
or a similar substance to prevent air leakage. (Fig. 3-7)

3-4. Installing the Drain Pipe

(1) Prepare standard hard PVC pipe (O.D. 32 mm) for the drain
and use the supplied drain socket to prevent water leaks.
The PVC pipe must be purchased separately.
When doing this, apply adhesive for the PVC pipe at the
connection point.

4. HOW TO INSTALL THE OUTDOOR
UNIT

4-1. Installing the Outdoor Unit

● Use concrete or a similar material to make the base, and
ensure good drainage.
● Ordinarily, ensure a base height of 5 cm or more. If a drain
pipe is used, or for use in cold-weather regions, ensure a
height of 15 cm or more at the feet on both sides of the unit.
(In this case, leave clearance below the unit for the drain
pipe, and to prevent freezing of drainage water in cold-
weather regions.)
● Refer to Fig. 4-1 for the anchor bolt dimensions.
● Be sure to anchor the feet with anchor bolts (M10). In
addition, use anchoring washers on the top side. (Use large
square 32 × 32 SUS washers with JIS nominal diameter of
10.) (Field supply)

4-2. Drainage Work

Follow the procedure below to ensure adequate draining for the
outdoor unit.
● For the drain port dimensions, refer to Fig. 4-1.
● Ensure a base height of 15 cm or more at the feet on both
sides of the unit.

4-3. Routing the Tubing and Wiring

● The tubing and wiring can be extended out in 4 directions:
front, rear, right, and down.
● The service valves are housed inside the unit. To access
them, remove the inspection panel. (To remove the
inspection panel, remove the 3 screws, then slide the panel
downward and pull it toward you.)
(1) If the routing direction is through the front, rear, or right,
use a nipper or similar tool to cut out the knockout holes for
the inter-unit control wiring outlet, power wiring outlet, and
tubing outlet from the appropriate covers A and B.
(2) If the routing direction is down, use a nipper or similar tool
to cut out the lower flange from cover A. (Fig. 4-2)

CAUTION
● Route the tubing so that it does not contact the
compressor, panel, or other parts inside the unit.
Increased noise will result if the tubing contacts these
parts.
● When routing the tubing, use a tube bender to bend the
tubes.
● In cold-weather regions, in order to prevent drainage
water from freezing, do not install the drain socket cap.
Also take steps to prevent water from accumulating
around the unit.
