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.
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.

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.

Start Up and Testing Test water - Make up water should be tested for Ph level and soluble salts. Ph must be between 6 and 9 and salt concentrates below 40,000 ppm. See “Pad Care” on page 14. Float valve - Open the water supply line to the sump. Adjust the float valve so the water shuts off before the water level in the tank reaches the top of the overflow pipe.
PDR 4" and 6” Evaporative Cooling System Start and End of Cooling Season At the end of the season, drain the pump and piping system to avoid damage caused by rust and impure particles in the water. If the system is outside of the building, you must drain and remove the pump to avoid freeze damage.
