PolarCool Performance
The following table shows estimates of the performance of four sizes of the PolarCool Evaporative Cooling System.
These values will vary depending on the particular installation and operating conditions. Both Variable Speed (VS)
and Single Speed (SS) models are listed.

Note 1: This estimate is under 90+ degree conditions; cooler temperatures will result in less
water usage.
Note 2: The cooling area is very dependent on the relative humidity, temperature, and the space
being cooled.
3.1 Temperature Differential Readings
The temperature drop from inlet to exit is very dependent on relative humidity and temperature. The higher
the ambient temperature and the drier the air, the greater the drop. A temperature drop of 10 to 20 degrees is
common.

Float Shown Ready For Operation
During shipment, the Float is securely
taped to the pan of the PolarCool.
Diagram 4C shows the Float with tape
removed and ready for operation.
CAUTION: Be careful not
to bend the Float Arm
when removing the tape!
4. Apply hand pressure to hold
float in place.
5. Carefully peel tape from float
with other hand.
6. Replace pads. Look for arrows on the side of
pad as shown in Diagram 4D.
NOTE: Ensure pads are replaced with
up arrow pointed UP.
Start Up and Shut Down
5.1 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.
5.2 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.

5.3 Breaking in New Pads
When pads are new, their slick surface will prevent the fast water absorption that will happen with older pads.
For this reason, it is important that the first time new pads are used, to allow the pump to run for two or three
hours. This will "soak-in" the pads, and allow faster start-up later.
After soaking new pads, turn off the pump, fan, and water supply, unplug the unit, and drain the reservoir.
This eliminates chemical residues that have washed out of the new pads. See Section 7 for more information
on Pad Care.
Foaming can occur with new pads. If excessive foaming is experienced, repeat the procedure described above
two or three times to flush chemical residues from the pads. Reducing the water flow to the pads may also be
helpful to reduce foaming.
NOTE: Do not allow the pump to run without water in the reservoir.
Without water, the pump may be damaged.
5.4 Setting Up for Operation
Warning!
Do not place the unit on a slope or where the unit can accidentally fall or roll into water.
The lockable wheels provide resistance to movement although
do not prevent movement or turn-over.
WARNING!
Use only on GFCI (Ground Fault Circuit Interrupt) protected receptacles.
1. Connect water hose to inlet tap.
NOTE: If desired, an optional customer supplied drain hose and cut-off valve
can be attached to the drain pan outlet beneath the PolarCool.
2. Check safety of electrical cords, and plug in unit.
3. Turn on water and fill the reservoir.
4. After the reservoir is filled, turn on the pump and let the water run for fifteen to twenty minutes
before turning on fan. See Section 6 for Control Panel details.
5. Turn on fan and enjoy the cool air output.
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.
NOTE: If water is not disconnected, turn off the water hose whenever the
PolarCool is not in use.
