5.5 Shut Down
When you are finished with the PolarCool, follow these steps for shutting down the unit.
1. Turn off pump.
2. Wait ten to fifteen minutes (This will dry the pad and minimize algae growth).
3. Turn off fan.
4. Disconnect water and power to the unit.
5. If water is not disconnected, turn off water hose to PolarCool whenever PolarCool is not in use.
6. Operation
6.1 Ventilation is Very Important
Fresh air is very important for proper operation of evaporative cooling. Ventilation can be provided by air flow
from open windows and doors, or exhaust fans. Positioning the PolarCool intake close to an open door is a
common way to assure fresh air. Evaporative cooling will not function properly in a closed environment.
6.2 Normal Operation
Under normal conditions, the pump should run constantly when air is being drawn through the pads. If outside
conditions are not warm enough to run evaporative cooled air, an alternative is to run the fan
with the pump off.
Dry the pads completely each night by turning off the pump and drawing air through the pads with the fan.
7. Maintenance
7.1 Maintenance Accessibility
Since evaporative coolers require maintenance, the PolarCool has been designed to make maintenance as easy as
possible. By simply raising the rear cover, basically all critical parts are within easy reach for inspection, including
the pads, spray bar, fan belt (48” model only), pump, strainer, and water reservoir. The 36 inch Single Speed
PolarCool has a special rear cover. To open, see the Figure below.
