Suspending The Indoor Unit; Installing The Refrigerant Tubing; Installing The Drain Pipe - Sanyo SPW-C706VH8 Instrucciones De Instalación

3-32. Suspending the Indoor Unit

Depending on the ceiling type:
●
Insert suspension bolts as shown in Fig. 3-91
or
Hole-in-anchor
Hole-in-plug
Suspension bolt (M10 or 3/8")
(field supply)
●
Use existing ceiling supports or construct a suitable support
as shown in Fig. 3-92.
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. 3-89 and 3-90)
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. 3-91.
(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. 3-93.

When brazing the gas tubing, cool the tubing with dampened
shopcloths as you work, as shown in Fig. 3-94, to protect the
unit's thermistor from the heat generated by brazing.

The tube connector that comes with the Type 90 indoor unit
cannot be used in combination with this outdoor unit.
Use in combination with the SPW-C0905H8.
●
The Type 70 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.

●
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. 3-95)

3-34. 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.
