Evaporative Cooling System User Manual

Section 1.4: Overview

The PolarCool Evaporative Cooling System (henceforth referred to as "the unit") reduces air temperature by drawing warm

ambient air across a water-soaked surface (the cooling pads), evaporating the water and dissipating the heat it has absorbed.

Simple controls make the unit easy to operate, and the overall design permits straightforward cleaning and maintenance. Casters

allow the unit to be moved by hand and set up anywhere with proper water and power supplies.

Section 2: Setup

Section 2.1: Install Casters (18" Units Only)

NOTICE: 24", 36", and 48" units are shipped with their casters pre-installed. If you have such a unit, skip to Section 2.2.

CAUTION: The unit is very heavy. Ensure it is well supported while you install the casters.

1. Align one of the caster brackets with one of the caster support channels on the bottom of the assemby.

2. Run four 5/16"-18 x 3/4" carriage bolts through the bracket and the support channel.

3. Place a 5/16" washer and a 5/16"-18 nylon insert nut on each of the bolts, then tighten the nuts until they are fully seated.

4. Repeat Steps 1-3 on the remaining casters.

Section 2.2: Float Valve

1. Li the cover at the top of the unit to access the cooling pads.

2. Remove the cooling pads, titling the spray bar if necessary.

3. Hold the float valve in place while peeling the tape from it. Be careful not to bend the float valve arm.

4. Reinstall the cooling pads, ensuring the "UP" and "Air Flow" arrows are oriented properly. Reorient the spray bar if necessary.

5. Close the cover.

Evaporative Cooling System User Manual

Section 3: Operation

The unit operates by pumping water from the reservoir through the spray bar to soak the cooling pads. Meanwhile, the propeller

draws warm air through the pads. The water evaporates as it pulled away from the pads; this evaporation dissipates the heat the

water has absorbed from the incoming air, thus cooling the outgoing air. Excess water returns to the reservoir to be recirculated.

Evaporative cooling reduces the dierence between the area's dry-bulb temperature (DBT; i.e. regular air temperature) and

wet-bulb temperature (WBT; i.e. temperature at 100% relative humidity) with approximately 75% eiciency. For example, at a DBT

of 85°F and a WBT of 65°F (a dierence of 20°F), the temperature on the outlet side of the unit would be reduced to approximately

70°F (a decrease of 15°F).

Section 3.1: Components

Section 3.1.1: Fan Motor

On 18", 24", and 36" units, the 115V fan motor can be operated at various speeds using the control panel. The propeller is mounted

directly to and driven directly by the motor sha.

On 48" units, the 240V fan motor can be operated at only one fixed speed. The motor is mounted to the side of the fan sha. It uses

a belt-and-pulley system to drive the propeller.

Evaporative Cooling System User Manual

Section 3.1.3: Control Panel (All Units) and Control Board (Not on 48" Units)

The control panel is located on the right side of the unit. It is the primary means of starting and stopping the fan and the pump.

On 18", 24", and 36" units, the control panel is connected to the control board (itself mounted inside the electronics enclosure),

which handles all operational logic. The board enables variable-speed operation and low-water-level pump shuto. The control

panel has multiple buttons that control fan power, fan speed, and pump power. It also has several LEDs that indicate the fan

status, fan speed, pump status, and water level status.

On 48" units, the control panel has a pair of toggle switches that turn the fan and pump on and o. There is no control board.

Section 3.1.4: Cooling Pads

These 8"-thick paper-based blocks are a key part of the evaporative cooling process. As they are saturated with water, warm air is

drawn through them to dissipate the absorbed heat by evaporation. They are coated for protection against both impacts and algae

formation. They must be installed in the labeled orientation to allow proper airflow.

Section 3.1.6: Liquid Level Switch (18", 24", and 36" Units)

When this switch senses the water in the reservoir is too low, it signals the control board to stop the pump, preventing it from

running dry.

Section 3.1.5: Float Valve

This brass valve, connected to the water inlet inside the unit, shuts o the inlet when the water in the reservoir reaches the depth

to which the valve has been set. This prevents the reservoir from being overfilled.

Section 3.1.2: Water Pump

The pump moves water from the reservoir through the spray bar and onto the cooling pads.

On 18", 24", and 36" units, the 115V pump is turned on and o using a button on the control panel. The unit control board has

low-water-level protection logic that prevents the pump from running without adequate water in the reservoir.

On 48" units, the 240V pump is turned on and o using a switch on the control panel. The pump does not have low-water-level

protection since there is no control board.

Section 3.2: Controls

Section 3.2.1: 18", 24", and 36" Variable-Speed Units

On a 18", 24", or 36" variable-speed unit, the control panel has the following inputs:

1. Fan Power - This button starts and stops the fan.

2. Fan Speed - These buttons adjust the speed of the fan between 10 presets. The "+" button increases the speed by one

increment, whereas the "-" button decreases the speed by one increment. The "-" button cannot be used to stop the fan.

The speed is indicated by the highest LED currently illuminated. Each LED corresponds to two speeds, with flashing

representing odd values (i.e. 1, 3, 5, 7, or 9) and solid green representing even values (i.e. 2, 4, 6, 8, or 10). For example, if the

bottom LED is flashing by itself, the speed is set to 1; if the first three LEDs are solid green, the speed is set to 6.

3. Pump Power - This button starts and stops the water pump.

The Pump section of the control panel also has the following indicator LEDs:

1. Unit Power - This LED (located behind the bottom logo) is solid red when the unit is powered on.

2. Pump ON - This LED is solid green while the pump is running.

3. Fill - This LED flashes green when the water level remains low for more than one minute. During this time, the pump will

automatically turn o, the Pump ON and Fill indicators will flash, and the Low Water indicator will turn solid red.

4. Low Water - This LED flashes red when the water remains low for less than one minute. Aer one minute, it turns solid red.
