4. Maintaining the PolarCool is very simple It only takes a small amount of time and effort If you follow the guidelines below your pads will last much longer and be much more efficient 7 3 1 Algae To prevent algae allow the pads to dry out each day by running the fan without the pump running until the pads are completely dry about 15 minutes 7 3 2 Scale Scale is a concentration of solids that plate the surface of the pads if the water contains too many impurities Scale formation can be prevented by using water with a pH between 6 and 9 and silica levels below 150 ppm If this is impractical scale can be minimized by increasing the drain off rate To clean pads spray pads frequently with water hose 7 3 3 Dirt and Dust If the pads are allowed to get excessively dirty they should be removed from the system and washed down with a water hose Manual No 4801 5035 Rev 2 09 PolarCool Page 11 of 26 7 3 4 Why Drain Water From The System If you have ever left a pot of coffee warming on the coffee maker you know the two principles at work in evaporative cooling systems First as the coffee sits on the warming plate the level of water in the pot goes down Second the remaining coffee gets stronger as the water evaporates In your cooling system these effects still apply As water evaporates no impurities are carried along This leaves all sorts of minerals chemicals and other impurities behind The concentration of impuri
