3-22. Increasing the Fan Speed

If external static pressure is too great (due to long extension
of ducts, for example), the air flow 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 the booster cable (sockets at both ends) clamped
in the box.
(4) Securely connect the booster cable sockets between the
disconnected fan motor sockets in step 2 (Fig. 3-75).

■ How to read the diagram
The vertical axis is the external static pressure (Pa) while
the horizontal axis represents the air flow (m
characteristic curves for "HT", "H", "M" and "L" fan speed control
are shown. The nameplate values are shown based on the
"H" air flow. For the 25 type, the air flow is 18 m
the external static pressure is 49 Pa at "H" position. If external
static pressure is too great (due to long extension of ducts,
for example), the air flow volume may drop too low at each air

outlet. This problem may be solved by increasing the fan speed
as explained above.
