Walls or Obstructions
The unit should be located so that air may circulate freely and not be recirculated. For proper air flow and access all sides of the unit should be a minimum of “W” away from any wall or obstruction. It is preferred that this distance be increased whenever possible. Care should be taken to see that ample
room is left for maintenance work through access doors and panels. Overhead obstructions are not permitted. When the unit is in an area where it is enclosed by three walls the unit must be installed as indicated for units in a pit.
Multiple Units
For units placed side by side, the minimum distance between units is the width of the largest unit. If units are placed end to end, the minimum distance between units is 4 feet.
Units in Pits
The top of the unit should be level with the top of the pit, and side distance increased to “2W”.
Decorative Fences
If the top of the unit is not level with the top of pit, dis- charge cones or stacks must be used to raise discharge air to the top of the pit. This is a minimum requirement.
Fences must have 50% free area, with 1 foot undercut, a “W” minimum clearance, and must not exceed the top of
unit. If these requirements are not met, unit must be installed as indicated for “Units in pits”.
* “W” = Total width of the fluid cooler.
