4. Open the valve in the pump discharge pipe.
5. Flush dirt and debri from the Trough by removing the Sump Drain Plug and
the Sump Screen.
6. Flush dirt and debri out of the Distribution Pipe by running the Pump with the
2” Expansion Plug removed from the end of the Distribution Pipe.
7. Check that the Sump Screen is clean.
8. If bleed-off is to be used, start with a flow rate of .25 gpm per 100 sq ft of
Evaporative Cooling Pad.
The correct amount of bleed-off depends on the amount of minerals and
chemicals in the water.
The initial bleed off rate can be adjusted, but should be maintained high enough
to prevent deposits on the face of the Evaporative Cooling Pad.
System Operation & Maintenance
1. 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 .25 gpm/100 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.
2. Shade the pads as much as possible to minimize algae growth.
3. Allow the pads to dry out completely once every 24 hours to kill algae.
4. Reduce the number of times the pad is wetted and dried out each day to
maximize pad life.
5. Clean the strainer and the sump screen regularly to maintian a sufficient supply
of water to the pads.
6. Periodically check the jets of water from the top of the Distribution Pipe. The
jets should spray approximately 8” to 11” (20 to 28 cm) straight upward.
7. Keep the Distribution Pipe holes free of debris. Use a small wire to clean
plugged holes. Clogged holes may cause dry streaks and lead to clogging of the
pad.
8. Every three months, the entire water system should be drained and disinfected
to help prevent algea growth.
9. If algae cannot be controlled by shading and disinfecting, a quaternary amine
can be added to the water to prevent algae growth, do not use chlorine,
bromine or any oxidizing boicide.
10. Regularly flush the Distribution Pipe by removing the 2” plug at the end of the
pipe and allowing the pump to run.
11. Periodically, gently hose and brush deposits from the front of the pads.
12. Completely drain the system for winter storage. Remove the Sump Drain Plug.
Remove the Pump.
13. Avoid contaminants such as dust, fertilizers, and harse cleaners.
14. The pH of the water being circulated through the system should be maintained
at between 6 and 9 to prevent premature pad softening.
15. Check that Cooling Pads are installed correctly. See
