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.
3.1Temperature 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.
4. Controls
The PolarCool Zone features a user friendly control panel interface with status indicator lights.

4.1Control Panel
•Power Indicator Light – The red Power Indicator Light is located at the bottom-center of the control panel label
and illuminates the Danger High Voltage Triangle. The Power Indicator Light remains ON constantly while
power is applied to the PolarCool unit.
•Fan Control ON/OFF Button – This button is used to start and stop the fan.
•+ and – Speed Control Buttons – Used to select the fan speed to any position between LO and HI. These
buttons control the fan speed only and do not turn the fan on or off.
•Water Pump Control ON/OFF Button – This button is used to start and stop the water pump.
•Pump ON – The green indicator PUMP ON light is ON solid when the water pump is running.
•Low Water – The red indicator LOW WATER light is ON blinking when the water level is low for less than 1
minute. After the first minute, the red indicator light is ON solid.
•Fill – The green indicator FILL light turns ON blinking when the water level has remained low for a constant
time of more than 1 minute. Also after the first minute of constant low water level, the water pump will
automatically turn off, the Pump ON and Fill green indicator lights will be blinking, and the Low Water red
indicator light will be ON solid.
NOTE: The water must be filled above the low level switch and remain above the switch for a minimum of 1
minute solid before the water pump will turn back On.

5. Installation and Preparation
5.1 Unpacking PolarCool
1. Carefully unpack PolarCool Zone from shipping carton. The unit
comes completely assembled and ready to use.
5.2 Start-Up
The PolarCool Zone is easy to prepare for operation. There are five easy steps.
1. Hook-up water hose to inlet tap.
2. Check safety of electrical cords, and plug in unit. Caution: The system must always be plugged into a three
conductor, grounded GFI (Ground Fault Interrupt), power source.
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.
Note: Float may be locked in the off position.
3. Turn on water supply.
4. On the PolarCool Zone control panel, turn on the pump. The pump itself will not activate until the low water
level switch is tripped. (See Figure A, page 8)
IF PADS ARE NEW:
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 to allow the pump to run for two or three hours with the fan set to low speed the
first time new pads are used. 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. The
reservoir can be drained using the Drain Outlet. This eliminates chemical residues that have washed out of the
new pads.
NOTE: Do not allow the pump to run without water in the reservoir. Without water, the pump may be
damaged.
Foaming can occur with new pads. If excessive foaming takes place, 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.
NORMAL OPERATION :
Let the water run for twenty to thirty minutes before turning on fan. This will allow time for the reservoir to
fill.
5. Turn on fan and enjoy the cool air output.

5.3 Shut Down
When you are finished with the PolarCool Zone, 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 supply 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 Zone has been designed to make maintenance as easy
as possible. By simply removing the pad cover plates and the pads, basically all critical parts are within easy reach
for inspection, including the pads, spray bar, pump, strainer, and water reservoir. To open, see figure on the next
page.

Pad Removal
7.2 Frequency Of Pad Replacement
PolarCool pads, produced from a cellulose base and impregnated with a plastic resin anti-rot agent, can give years of
trouble free operation with proper maintenance (3 to 5 years is typical).
7.3 Extending Pad Life
As you use the PolarCool system, you will notice the need for good preventive maintenance. Algae growth, scale
(hard crusty deposits), and dirt accumulation are typical problems associated with poor maintenance.
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.
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 impurities in the reservoir and
system will quickly rise.
Drain the reservoir daily in dusty conditions, and twice a week in clean air.

7.3.5 Water Distribution
Maintaining even water distribution to the pads is the most important way of extending pad life. If an area of pad
does not receive enough water, cooling efficiency will be degraded. The Spray Bar Adjustment Valve should be
increased until the pads are fully wet, but not to the extent that a mist is blown out of the fan.
Dry spots or streaks can also be caused by clogged holes in the spray bar. Investigate by removing the pad cover
plates and running a pipe cleaner, or small dowel into the holes in the spray bar to clear any clogged holes. The
spray bar end caps may be removed for easier cleaning. Ensure the holes in the spray bar point upward during
operation.
7.4 Flushing the Reservoir
The pads and the complete water system should be flushed out at least once a week and the reservoir wiped clean.
1. Turn off the pump, fan, and water source, unplug the unit and drain the reservoir. The reservoir can be drained
using the Drain Outlet.
2. Wipe out the reservoir.
NOTE:Do not allow the pump to run without water in the reservoir. Without water, the pump may be damaged.
3. Restore the water source and fill the reservoir.
4. Run the pump for at least 15 minutes.
5. Pump the reservoir out again and refill with fresh water.
6. Start the pump and fan.
