MODEL AGZ CHILLERS
Case 3: Three or More Units, Side-by-Side
For all models, there must be a minimum distance between
any units placed side-by-side; however, performance may be
aected at this distance. Minimum distances are: models 030
to 070 - 4 feet, models 075 to 101 - 5 feet, models 110 to 241
- 6 feet. Figure 9 and Figure 10 depict Case 3 performance
adjustments as the distance between units increases.
NOTE: Data in Figure 9 and Figure 10 is for the middle unit
with a unit on each side. See Case 2 adjustment
factors for the two outside units.

Case 4: Open Screening Walls
Decorative screening walls are often used to help conceal a
unit either on grade or on a rooftop. When possible, design
these walls such that the combination of their open area
and distance from the unit (see Figure 11) do not require
performance adjustment. If the wall opening percentage is less
than recommended for the distance to the unit, it should be
considered as a solid wall. It is assumed that the wall height is
equal to or less than the unit height when mounted on its base
support. If the wall height is greater than the unit height, see
Case 5: Pit Installation for performance adjustment factors.
The distance from the sides of the unit to the side walls must
be sucient for service, such as opening control panel doors.
For uneven wall spacing, the distance from the unit to each
wall can be averaged providing no distance is less than 4 feet.
Values are based on walls on all four sides.
