3-31. Increasing the Fan Speed (280 Type Only)
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 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. 3-83.

(5) Place the cable neatly in the box and reinstall the cover
plate.
