Caution For Ducting Work; Increasing The Fan Speed (90 Type Only) - Sanyo SPW-C706VH8 Instrucciones De Instalación

(2) If connecting a drain joint (supplied) to the threaded drain
port, first wrap the drain port threads with sealing tape, then
connect the joint. (Fig. 3-96)

(3) After connecting the drain pipe securely, wrap insulator
(field supply) around the pipe.
(4) Ensure the drain pipe has a downward gradient (1/100 or
more) and prepare traps as indicated in Fig. 3-97.

(5) Also, in another part of the pipe arrangement, prepare traps
with an inspection plug to clean dust or debris that may
cause leaking of water. (Fig. 3-98)

(6) After connecting the drain piping, slowly pourwater into the
drain pan to check that the waterdrains smoothly.

3-35. Caution for Ducting Work

●
This unit has high static pressure (applicable external static
pressure Max. 167 to 216 pa (17 – 22 mm Aq). In the case of
small pressure resistance (for instance, a short duct), install
a damper for adjusting airflow volume as airflow volume /
airflow noise increases.
●
If the air conditioner is to be installed in a room such as
an office or meeting room which needs a low sound level,
provide a supply and return noise absorption chamber with
an acoustic liner.
●
Include an air filter (field supply) at the return duct.

How to Read the Diagram
The vertical axis is the External Static Pressure (mmAq) while
the horizontal axis represents the Air Flow (m
characteristic curve for the "H," "Med," and "Lo" fan speed
control.
The nameplate values are shown based on the "H" airflow.
Therefore in the case of 70 Type, the flow is 56 m
while the External Static Pressure is 17.8 mmAq at "H" position.
If the external static pressure is too great (due to long extension
of duct, for example), the airflow volume may drop too low at
each air outlet.

3-36. Increasing the Fan Speed (90 Type Only)

If external static pressure is too great (due to long extension
of ducts, for example), the airflow volume may drop too low at
each air outlet. This problem may be solved by increasing the
fan speed using the following procedure:
(1) Remove 4 screws on the electrical component box and
remove the cover plate.
(2) Disconnect the fan motor sockets in the box.
(3) Take out 2 booster cables from option carton box (sockets
at both ends).
(4) Securely connect the booster cable's 2 sockets between the
disconnected fan motor sockets in step 2 as shown in Fig. 3-99.
