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. The amount of moisture that the air will absorb depends on the state of the air, or specifically, how muc

B. Humidity and Evaporative Cooling. A given volume of air at a certain temperature and pressure has the ability to absorb and hold a certain amount of water vapor. If that volume of air contains 50% of the amount of moisture that it is capable of holding, it said to be at 50% relative humidity. The higher the temperature of the air, the higher the amount of moisture it is capable of holding. Any change in the temperature without a corresponding change in the pres- sure results in an increas

II. SETup A. unpacking the pORT-A-COOL® unit. The standard 24”, 36” and 48” electric models of the PORT-A-COOL® unit are shipped completely assembled and sitting on a plastic pallet with a large cover box strapped over the 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® unit. The 16” model PORT-A-COOL® units are shipped in an enclosed corrugated box

III. OpERATInG pROCEDuRES Specifications Each model of the PORT-A-COOL® unit has its own set of operational specifications, sizes, weights, volt- age frequency, current requirements, etc. Please ask for the specifications for your model from your distribu- tor or check the serial number plate. B. placement of the pORT-A-COOL® unit. pORT-A-COOL® unit should be used in well-ventilated areas only.

D. Starting the pump and adjusting the water flow. CAuTIOn - DO nOT Run puMp WHEn SuMp IS DRY. Once the sump tank is full, moving the pump switch to the “ON” position will turn on the pump. When initially turning on the pump, the level in the sump will drop suddenly and restart the flow of supply water. This is a normal condition, as the cooling pads require a large amount of water for proper wetting. When the PORT-A-COOL® unit is new, the new pads will require an initial ‘breaking-in’ period.

IV. MAInTEnAnCE & STORAGE Very little maintenance is actually required on the PORT-A-COOL® unit. The primary topic that accounts for most of the maintenance is cleanliness. 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 condition. The rugged, corrosion-resis- tant construction of the PORT-A-COOL® unit and industrial grade components make for the low maintenance characteristics. In exceedingly dusty or dirty envir

V. TROuBLESHOOTInG / REpAIR A. Troubleshooting The most common problems encountered with a PORT-A-COOL® unit are operational problems. The PORT-A-COOL® unit consists of three systems. It is important to determine which system of the PORT-A- COOL® unit the problem is associated with. Certain problems may be associated with more than one sys- tem. When determining which system that the problem is associated with you must first define the problem, i.e., the pump is not running. Although this

WATER SYSTEM The water system consists of three primary elements: 1) Water Delivery System, 2) Spray Bar Assembly; 3) Pump. Troubleshooting of this system is fairly simple. The Water Delivery System consists of two assemblies: A) The Water Inlet assembly and B) The Plumbing assembly. The Water Inlet assembly is made up of three components: 1) The bulkhead fitting, 2) The float valve con- nection hose and 3) The float valve. The Plumbing assembly consists of three elements: 1) Riser (PVC comp
