3-16. 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. 3-52).

■ How to read the diagram
The vertical axis is the external static pressure (Pa) while the horizontal axis represents the air flow (m
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
3
73 type, the air flow is 18 m /minute, while 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.

3-17. Required Minimum Space for Installation and
Service
● This air conditioner is usually installed above the ceiling so
that the indoor unit and ducts are not visible. Only the air
intake and air outlet ports are visible from below.
● The minimum space for installation and service is shown in
the diagram. (Fig. 3-54)
● *H dimension means the minimum height of the unit.
● Select the *H dimension such that a downward slope of at
least 1/100 is ensured as indicated in "3-22. Installing the
Drain Pipe".
