6 Planning Information " Recirculating Evaporative Cooling Planning Information System Layout: The Sump Assembly may be installed at either end of the system or in the middle. Maximum Length - 70' MV-00 Maximum length = 70 Figure. Optional Sump locations The maximum length of Cooling Pad on either side of the Sump Assembly is 70', if the cooling system is longer than 70' the Sump must be installed in the middle of the system. The maximum amount of slope is -/"[8 mm] per system. The Sump end must be level with, or lower than the rest of the trough.

7 " Recirculating Evaporative Cooling Framing Information Framing Information Figure shows two options for installing the cooling pad relative to the tunnel curtain and provides information for the Evaporative Cooling System opening with Sump on either end. See Figure for opening information for Evaporative Cooling System with Sump in the middle It is recommended to frame the Pad opening using treated lumber. Note:. Determine the location of the bottom stringer. See Figure, Item. Use Wood or Lag Screws to secure the Bottom Stringer to the Studs. The Lower Stringer must be capable of supporting 0 lbs/ft [ kg/m] plus lbs/ft [ kg/m] for each foot of Cooling Pad Height. Example: A ' Cooling Pad requires a Stringer capable of supporting 0 lbs/ ft + ( lbs/ft x ') = 8 lbs/ft.. Determine the location of the top stringer. See Figure, Item 8. The distance between the top and bottom stringers should be approximately -/'' [8 mm] less than the height of the Evaporative Cooling Pads. Example: For a 0'' [ mm] tall Evaporative Cooling Pad the distance between the stringers would be 0'' [ mm] - -/'' [8 mm] = 8-/'' [8 mm]. The slope (if any) of the top stringer must be the same as the bottom stringer.. Snap a chalk line on the lower stringer at the locations specified in Figure, Item. This chalk line will determine the location of the lag screws for the Trough Supports.. Snap a chalk line on the top stringer at the locations specified in Figure, Item &. This chalk line will determine the location of the Splash Plate lower holes.. A short section of x treated lumber (Figure, Item 0) is required beneath the Bottom Stringer at the Sump end to provide a back support for the Sump assembly. 7

Adjusting Initial Water Level After the system runs for a while and turns off, the water level will rise.-.0'' above the level it was initially set at.. Open the valve in the pump discharge pipe.. Flush dirt and debris out of the Distribution Pipe by running the Pump with the -/" Ball Valves opened. After flushing the pipe out, close the -/"' Ball Valve at the end opposite the Sump.. With the Pump running, adjust the -/" Ball Valve,at the Sump end, so the height of the water jets is " to " [0 mm to mm] above the top of the Distribution Pipe at the end opposite the Sump. 7. If bleed-off is to be used, Adjust the Bleed Off Valve to a flow rate of 0. gpm per 00 sq ft. of Evaporative Cooling Pad. The correct amount of bleed-off depends on the amount of minerals and chemicals in the water. The bleed off rate can be adjusted over time, but should be maintained high enough to prevent mineral deposits from accumulating on the face of the Evaporative Cooling Pad.

27 " Recirculating Evaporative Cooling System Operation & Maintenance System Operation & Maintenance. Reduce the mineral and chemical build-up in water by; a). Bleeding water off the system. Begin by adjusting the Bleed-Off Valve to drain. gpm/00 sq ft. of Cooling Pad while the Pump is running. Increase the bleed-off rate if minerals build up on the face of the Cooling Pad b). Draining all the water from the system once a week during operating season. Increase the frequency if minerals build up on the face of the Cooling Pad.. Shade the pads as much as possible to minimize algae growth.. Allow the pads to dry out completely once every hours to kill algae.. Reduce the number of times the pad is wetted and dried out each day to maximize pad life.. Clean the strainer regularly to maintain a sufficient supply of water to the pads.. Periodically check the jets of water from the top of the Distribution Pipe. The jets should spray approximately " to " [0 mm to mm] straight upward at the end of the Distribution Pipe opposite the Sump. 7. Keep the Distribution Pipe holes free of debris. A /" drill bit may be used to clean the holes or a large round brush may be attached to /" pvc pipe and pushed through the Distribution Pipe to clean out the holes. The " Pipe Plugs at either end of the Distribution Pipe can be removed to allow cleaning brush access. Clogged holes may cause dry streaks and lead to clogging of the pad. 8. Regularly flush the Distribution Pipe by opening the -/'' Ball Valve at the end of the sediment trap (See Figure, Item ) and allowing the pump to run. 9. Periodically, gently hose and brush deposits from the face of the pads. 0. Completely drain the system for winter storage. Remove the Sump Drain Cap. Remove the Pump.. Avoid contaminants such as dust, fertilizers, and harsh cleaners.. The ph of the water being circulated through the system should be maintained at between and 9 to prevent premature pad softening.. Check that Cooling Pads are installed correctly. See Figure 0 through Figure.. The water holding capacity of pads increases as pads age. This extra water raises the Sump water level when the system shuts down. To prevent overflow at shut down, slightly lower the float level. 7
