Page 3: Building Preparation
Building Preparation Location of Pad System: Typical Pad/Fan Relative Locations The Kool-Cel pad should be placed away from the fans (opposite) so that cooled air can flow through the building without turbulence. Pads should be no more than 250’ from the fans in greenhouse buildings to avoid excessive temperature rise and velocities. -
Page 4: System Installation
PDR 4" and 6” Evaporative Cooling System Sump Tank and Cover Provide a tank with a capacity of 3/4 gallon per square foot of pad area for 4” pads and 1 gallon per square foot of pad area for 6” pads. A tank cover should be provided capable of supporting the pump (#30-35 lbs., #60-50 lbs.). The sump should be set in place prior to start of the installation of the distribution and return system. - Page 5 Gutter Support Bracket 2" x 6" Bottom Stringer 1/4" x 1 ½" Hex Head Screw Figure 3 Install all gutter support brackets (1) as shown in figure 3, making sure brackets are vertical.

- Page 6 PDR 4" and 6” Evaporative Cooling System System Top Installation Beginning at the drain end, install the top cover support sections and the pipe hangers to the top stringer by lining up the top holes of the top cover support sections with the chalkline on the top stringer.
- Page 7 Install a 1 ½” slip joint coupling on the pipe end away from the drain and assemble another 10’ section of pipe. Do not use PVC cement on these joints. The coupling and pipe should be pushed tightly together but not cemented. Make sure the metered holes are at the top so the water will spray directly upward for proper water distribution.

(Installing pads with top cover in place could result in pad damage and the “springing” of the top cover which could result in improper channeling of the water.) Place the bottom of the pad firmly on the pad support and under the pipe as shown in figure 15 for 4”...
