1-4 Indoor Fan Performance
If external static pressure is too great (due to long extension of ducts, foe 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 the screw 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 the Fig. 1-1
(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 orizzontal one is the AIR FLOW RATE (m3/h).
The characteristic curves for HH, H, M and L fan speed
are shown. The nameplate values shown are based on the
H air flow rate. For the type 7/9/12 flow rate is 600 m3/h
while the external static pressure is 49 Pa at H position.
If external static pressure is too great (due, for example,
to long duct extension), the air flow rate may drop too
much at each air outlet.
This problem can be solved increasing the fan speed
with the booster cable.
