9-8. Suspending the Indoor Unit
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. 1-33 and 1-34)
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. 1-35.
(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. 1-37.
3. Installing the Refrigerant Tubing
The size of the refrigerant tubing is as shown in Table 1-5.

When brazing the gas tubing, cool the tubing with dampened
shopcloths as you work, as shown in Fig. 1-38, to protect the
unit’s thermistor from the heat generated by brazing.

The tube connector that comes with the Type 250 indoor unit
cannot be used in combination with this outdoor unit.
Use in combination with the U-250PE1E8.
Depending on the ceiling type:
Insert suspension bolts as shown in Fig. 1-35
or
Use existing ceiling supports or construct
a suitable support as shown in Fig. 1-36.
