SYSTEM LIMITATIONS (Continued)
AQUASONIC Atomizer Parameters (Continued)
Sidewall Position (Continued)
• For ceiling heights greater than 16 ft 5 in. (5.0 m), half the
total number of atomizers shall be in the upper half of the
room. Half the total number of atomizers shall be in the
lower half of the room and will be vertically spaced
between 6 ft 8 in. (2.0 m) and 17 ft (5.2 m) apart. The
atomizers shall be located at a minimum of 3 ft (0.9 m)
below the ceiling and no less than 6 ft 8 in. (2.0 m) above
the floor.
• Refer to Figure 9a through 9d for application of the side-
wall constraints.
Application of Pendent Contraints
Rectangular Array

• Atomizer spacing (L1 and L2) may be between 10.5 ft
(3.2 m) and 17 ft (5.2 m) apart, but L1 and L2 do not have
to be the same distance. As the number of atomizers in
the array increases, the atomizers are equally spaced in
each direction. Allowances may be made in the event of
obstructions, but must remain within the maximum and
minimum distance.
• The wall spacing (WS1 and WS2) may be between 3 ft
(0.9 m) and 8.5 ft (2.6 m), but do not have to be the same
distance. The wall spacing requirements apply to all
atomizers along a wall. In a uniform array, WS1 is usually
half of L1 and WS2 is half of L2. Allowances may be
made to accommodate for the equipment layout or
obstructions, but the wall spacing must remain within the
maximum and minimum distance.
• The maximum rated area one atomizer can cover is
289 ft
2
(27 m
2
). This is equivalent to a 17 ft by 17 ft (5.2 m
by 5.2 m) square area. The rated area coverage will be
decreased as the ceiling height increases above 12 ft
8.5 in. (3.9 m). See the Design section in this manual for
ceiling height calculation instructions.
Triangular Array
FIGURE 8b
008507
• A triangular array has a minimum of 5 atomizers, and the
pattern may be increased in increments of 3 atomizers.
• Atomizer spacing (L) is defined as the distance from the
center atomizer to each peripheral atomizer and may be
between 10.5 ft (3.2 m) and 17 ft (5.2 m) apart. The
distance from the center atomizer to each of the periph-
eral atomizers should be equal; however, allowances may
be made in the event of obstructions. Atomizer spacing
must remain within the maximum and minimum distance.
• The distances X1 and Y1 may vary, and are not held to
the maximum spacing limitation; however, they may not
be less than 10.5 ft (3.2).
• The wall spacing (WS1 and WS2) may be between 3 ft
(0.9 m) and 8.5 ft (2.6 m), but do not have to be the same
distance. The wall spacing requirements apply to all
atomizers along a wall. In a uniform array WS1 and WS2
are usually half of L. Allowances may be made to accom-
modate for the equipment layout or obstructions, but must
remain within the maximum and minimum distance.
Note:
The center atomizer is not held to the wall spacing
requirements.
