1-11 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 jumper cable (sockets at both
ends) clamped in the box.
(4) Securely connect the jumper cable sockets
between the disconnected fan motor sockets in
step 2.
(5) Place the cable neatly in the box and reinstall
the cover plate.

■ How to read the diagram
The vertical axis is the external static pressure (Pa) while the horizontal axis represents the AIR FLOW (CFM).
The 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 24 type, the air flow is 636 CFM, while the
external static pressure is 49 Pa at “H” position. If external static pressure is too great (due to long extension of
duct, 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.
