I. INTRODUCTION The PORT-A-COOL® unit is a fully self-contained, portable, high efficiency evaporative cooler that is proudly made in America at our Center, Texas factory. A. What is Evaporative Cooling? When trying to understand evaporative cooling, it may be best to think of air as being like a sponge, in that regard, air has an ability to absorb moisture that it comes in contact with.
It is important to realize that the temperature of the water does not have a great effect upon the cooling produced by the evaporation. If you were to place a gallon of 50˚F water on a warm sidewalk, it would consume 9,000 BTU's during its evaporation, thus making the side- walk 9,000 BTU’s cooler.
ing, and the relative humidity of the air would drop to 50%. The hotter the day, the drier the air becomes, and the more cooling that can take place through the evaporation of water. This means that when the day gets hot enough to require cooling, the relative humidity will be much lower than in the morning and will allow an evapo- rative cooling device to work more effectively.
B. Removing the cooling media. (Disconnect Electric Power) Caution - Disconnect power before performing this operation!! The PORT-A-COOL® unit should now be exposed to allow removal of the cooling media (pads). Although removal of the cooling media is for visual inspection and service and clean- ing only it is not necessary to remove for the initial setup.
Electrical Connection PORT-A-COOL® unit must be in the upright position with cooling pads installed! All models utilize a single power cord and control switches. Before connecting the plug to an outlet, insure that there is no standing water where the cord may lie. Check the chart below to determine what the electrical requirements for your specific model may be.
A primary consideration when actually deciding where to place the PORT-A-COOL® unit is the direction of the airflow. The PORT-A-COOL® unit creates a fan-shaped air pattern that disburses the air over a large area. This pattern may be disturbed or broken up by obsta- cles such as shelves, work benches, etc.
When the PORT-A-COOL® unit is new, the new pads will require an initial 'breaking-in' period. This period is required for the pads to begin readily absorbing water. It may require up to a week to achieve maximum efficiency. It is important to insure that the spray bar is properly adjusted when first starting the water flow in the PORT-A-COOL®...
Once the sump is drained and the power disconnected, the pads may be removed to allow inspection of the sump tank. Assuming that the PORT-A-COOL® unit is in a dusty envi- ronment, dust will collect in the sump tank over time. This dirt and any remaining water may be vacuumed out using a wet/dry shop vacuum and wiped clean with a cloth.

Although the PORT-A-COOL® unit is designed to be simple to maintain, it will be necessary to have some basic hand tools (screwdrivers, pliers, adjustable wrenches, etc.) as well a volt/ohm meter for troubleshooting the electrical system. FAN SYSTEM This section is divided into the two categories of fans used on all PORT-A-COOL® models: Direct Drive and Belt Drive.
DIRECT DRIVE MODELS PROBLEM CHECK SOLUTION Fan motor won't run and Power cord, extension cord, Check switch connection makes no sound. switches, circuit breaker, etc. Reconnect power or extension cord, reset breaker. Blade in contact with shroud Check mounting bolts. Fan motor won't run and makes a humming sound.

Direct Drive Models 1) Disconnect the 5-pin quick release connector from the switch harness inside the switch box by removing the cover-plate. 2) Note the distance that the front of the motor shaft extends past the fan blade hub. Loosen the setscrew that attach fan blades to motor shaft and remove the fan blade.

B. Port-A-Cool® Unit Limited Warranty For one year from date of installation, General Shelters of Texas, S.B., Ltd., warrants any original component part or parts of the Port-A-Cool® evaporative unit found, upon examination by factory authorized personnel, to be defective in material or workmanship. All transportation charges on parts submitted for replacement or repair under this warranty must be borne by the purchaser.
FREQUENTLY ASKED QUESTIONS Q. IS THERE ANY ASSEMBLY REQUIRED? A: No. Port-A-Cool® units are ready to use right out of the box. Q. HOW DO I PREPARE MY PORT-A-COOL® UNIT FOR STORAGE? A: Simply drain the unit, dry out the pads and place the unit, preferably covered, in a dry place for the winter season.

Q. WHAT SHOULD I DO IF MY UNIT SMELLS? A. A new unit will go through a break-in period and may emit some odor. Approximately after two weeks of operation, the odor should disappear. If the unit is not a new unit, algae or bacteria growth in the unit from improper maintenance will cause odors.
