Unpacking the PORT-A-COOL® unit. B. Removing the cooling pads. C. Connecting the water and electricity or air.
As the heat is removed from an object, the tempera- ture of that object is decreased. In the case of the PORT-A-COOL® unit, heat is removed from the air, reducing the temperature of the air.
14 (53.0 liters or 11.7 Imperial Gallons) 121,800 For actual temperature drops refer to Appendix A. In simple terms, evaporative cooling is nature’s way of cooling. The PORT-A-COOL® unit uti- lizes the same phenomenon, but in an extremely efficient manner. B. Humidity and Evaporative Cooling.
PORT-A-COOL® unit. It is a simple matter to cut the straps and remove the box by lifting it over the PORT-A-COOL® unit. Remove the protective plastic dust cover to expose the PORT-A-COOL®...
After the PORT-A-COOL® unit has been thoroughly tested at the factory, a special 2-sided brass hose adapter is attached to the water inlet on the side of the PORT-A-COOL® unit, which is below the spray bar adjustment and drain valves. A standard garden hose is attached to this brass hose adapter and cinched down to preclude leaks.
There are three primary considerations when deciding where to place the PORT-A-COOL® unit. 1) Fresh Air Supply - The inlet side of the PORT-A-COOL® unit (pad side) must be placed so as to insure that a smooth, uninterrupted supply of fresh air is available.
PORT-A-COOL® unit is stable, well constructed, and will not allow the PORT-A-COOL® unit to tip over. The PORT-A-COOL® unit must be level and in the upright position. When sup- porting with a platform allow for the full weight of a functioning PORT-A-COOL® unit by including the weight of the water both in the sump tank and the added weight of the water saturated cooling pads.
Keeping the PORT-A-COOL® unit clean will do more than any other single item to keep your PORT-A-COOL® unit in peak operating condi- tion. The rugged, corrosion-resistant construction of the PORT-A-COOL® unit and industrial grade components make for the low maintenance characteristics.
2) Roll up the electrical power cord and secure it to ensure that it will not be rolled over, tripped over or caught in equipment. 3) Cover the PORT-A-COOL® unit completely to prevent dust build-up and store in a dry area. This also helps prevent damage to the pads. Optional dust covers are available from your distributor.

FAN SYSTEM This section is divided into the two categories of fans used on all PORT-A-COOL® models: Direct Drive and Belt Drive. Both have some symptoms in common, and both have problems that are particular to each.
The Spray Bar Assembly consists of two components: 1) Spray Bar, 2) 4 foot connection hose. The pumps that actually move the water through the delivery system are discussed in the charts below. These charts indicate the major symptoms of problems that may be encountered with the Water System components. 2004 PORT-A-COOL® Unit Electric Models...

7) Reconnect the 5-pin quick release connector to the switch and re-secure the switch box cover-plate. 8) Replace the motor wiring cover-plate and inspect to be certain that the rubber seal is properly seated. 9) Replace the cooling pads, reconnect the unit power and test motor. 2004 PORT-A-COOL® Unit Electric Models...
VI. REPLACEMENT PARTS A. Returned Merchandise Authorization (RMA) Procedures All Port-A-Cool® units, parts, or materials being returned to General Shelters for warranty replacement or repair require an RMA (Return Merchandise Authorization) number. There are two methods for replacing warranty parts: 1.
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.
