1. Warnings ! WARNING • • • Whenever water and electricity are combined in the same enclosed environment the possibility of electric shock exists. This unit must only be plugged into a three conductor, grounded GFI (Ground Fault Interrupt), power source. Do not open the unit with power applied to the unit. Do not place the unit on a slope or where it can accidentally fall or roll into water. Wiring And Connections Must Comply With All National And Local Electrical Codes.
3. PolarCool Performance The following table shows estimates of the performance of the PolarCool Zone Evaporative Cooling System. These values will vary depending on the particular installation and operating conditions. PolarCool Model Drive Water Consumption Rates (See Note 1) 36” VS Direct 12 gallons per hr.

Solenoid Valve Full Level Switch Low Water Level Switch FIGURE C 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.
Pad Cover Plate Thumb screws Pad Instructions: 1. Unscrew thumb screws and remove pad cover plate. 2. Remove Pads. 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.
Drain Outlet W/Cap 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.
7.5 Cleaning the Pump Filter The water pump includes a removable plastic filter on the bottom of the pump which should be cleaned weekly when the reservoir is flushed. NOTE: Do not allow the pump to run without water 1. Turn off the pump, fan, and water source, and unplug the unit. in the reservoir. Without water, the pump may be 2. Remove the pump from the reservoir, remove damaged. and clean the screen on the bottom of the motor, 3. Restore the water source and fill the reservoir.
Flow Control Valve 7.9 Flow Control Adjustment The Flow Control Valve for the PolarCool Zone is shown to the right. Flow adjustments are factory preset, however can be adjusted by the user based upon local water pressure and evaporative conditions at the site. The amount of water flow affects the efficiency and operation of the PolarCool Zone. During operation the flow should be adjusted so that sufficient water soaks the pads, but only enough to completely soak the pads.
8 PolarCool Preventive Maintenance Requirements • • • • • • • • Flush the system at least once per week and wipe the reservoir clean to prevent damage to the unit. Refer to Section 7.4. 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). Drain the system during extended shutdowns. Disinfect the whole system once per quarter. Inspect spray bar for debris in holes.
