CAUTION
Be careful since the fan will start when you short
the pin on the indoor control board.
(4) When the check of drainage is complete, open the check pin (CHK) and
remount the insulator and drain cap onto the drain inspection port.
3-24. Increasing the Fan Speed
If external static pressure is too great (due to long extension of ducts, for
example), the air fl ow volume may drop too low at each air outlet. This problem
may be solved by increasing the fan speed using the following procedure:

NOTE
(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 as
shown in Fig. 3-98.
(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 (in. WG) while the horizontal axis
represents the air fl ow (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 fl ow. For the 18 and 24 types, the
air fl ow is 635 CFM, while the external static
pressure is 0.20 in. WG at “H” position. If
external static pressure is too great (due to
long extension of ducts, for example), the air
ow volume may drop too low at each air
outlet. This problem may be solved by
increasing the fan speed as explained
above.
