CAUTION! If the duct network does
not provide the external static
pressure stipulated on selection, it
will have repercussions on the air
flow and therefore on the unit's
performance.
Please refer to "Selection of the
Proper Available Static Air Pressure".
This type of problem may if
necessary be referred to the Trane
service office, which may be able to
advise you as to the necessary
modifications, if any.
On all units, a straight duct section
connected to a fan must have at
least the same cross sectional area
as the output panel orifice, and its
minimum length must be one and a
half times the fan diameter, before
any bend or deviation.
There must be no tight bends,
particularly at the fan output where
the air velocity gradient is high. A
large proportion of the air initially
flows at the top of the duct. If a bend
is close to the fan it must be
installed so that its external
curvature radius is in the trajectory
of the air discharged by the high
speed side of the fan (see figures 5
and 6).
