I. INTRODUCTION PAC2K48HZ 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.
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.
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.
III. OPERATING PROCEDURES A. Specifications Each model of the PORT-A-COOL® unit has its own set of operational specifications, sizes, weights, voltage frequency, current requirements, etc. Please ask for the specifications for your model from your distributor 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. There are three primary considerations when deciding where to place the PORT-A-COOL® unit.
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-resistant construction of the PORT-A-COOL® unit and industrial grade components make for the low maintenance characteristics.
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-ACOOL® unit the problem is associated with. Certain problems may be associated with more than one system. When determining which system that the problem is associated with you must first define the problem, i.e., the pump is not running.
BELT DRIVE MODELS PROBLEM CHECK Fan motor won’t run and Power cord, makes no sound. switches, circuit breaker, etc. SOLUTION Check switch connection Reconnect power, reset breaker. Blade in contact with shroud Check mounting bolts. Motor stalled (will not turn by hand) Replace motor. Breaker trips or fuse blows when fan is started. Motor stall (as above). Replace motor. Other items on circuit. Remove other items. Motor overheating and shutting off and restarting several minutes later.
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 connection hose and 3) The float valve.
SPRAY BAR ASSEMBLY (ALL MODELS) PROBLEM Too many dry streaks in the pads. CHECK SOLUTION Holes in spray bar blocked by foreign material. Remove and clean spray bar. Clean individual holes. Water spitting from the unit. Hose connection loose. Tighten hose. Replace hose and washer. Reseat spray bar end caps Excess water in air Pad Installation coming from the fan. Pads must be installed according to air flow direction label on the pad.
BRONZE PUMP (PAC2K36HZ or PAC2K48HZ) PROBLEM CHECK SOLUTION Power cord, switches, circuit breaker, etc. Reconnect power, reset breaker. Object jammed into impeller blade. Remove object. Prime pump. Air Locked. Pump/Motor locked. Replace pump/motor. Pump makes loud noise while running Pump bearings. Object in impeller housing. Replace pump. Clear object. Breaker trips or fuse blows when switch is turned on. Pump motor locked. Replace pump/motor.
B. Repair and Replacement Procedures Ensure that all water is removed from the PORT-A-COOL® unit and all power is disconnected. Remove all impediments to access the component you are checking or replacing. REPLACING THE COOLING MEDIA (Pads) (All Models) Caution - Disconnect power before performing this operation!! The flap must be removed to allow access to the cooling pads. Start with the center pad, which should be tilted out from the top and lifted out of the drain trough.
APPENDIX A FAN MOTOR REPLACEMENT Belt Drive Models (PAC2K361S, PAC2K363S, PAC2K482S) 1) DISCONNECT POWER and remove the pads as shown on page 15. 2) Motor is located in center of unit. Switchbox is located in upper left. (Figure 1) Locate motor harness wire secured to fan bracket assembly using plastic ties. Cut and remove plastic wire ties. DO NOT CUT ELECTRICAL HARNESS WIRES. 3.) Remove switch box cover. (Figure 2) Unplug motor wire harness connector.

PUMP REPLACEMENT MODELS PAC2K163S, PAC2K163SHD, PAC2K16HPVS APPENDIX A 1-B 1) DISCONNECT POWER and remove pads as shown on page 15. 2) Remove output tubing from insert fitting on base of pump. (Figure 1-A) 3) Remove the switch box wiring cover and disconnect the 4-pin 1-C quick release connector from the pump switch assembly. (Figure 1-B) 4) Remove the pump from the sump tank by removing two screws that hold the pump cover and pump in place.

FREQUENTLY ASKED QUESTIONS ® FREQUENTLY ASKED QUESTIONS Q. IS THERE ANY ASSEMBLY REQUIRED? A: No. Port-A-Cool® units are ready to use right out of the box. (continued) Q. HOW DO I OIL THE FAN MOTOR? A. The Emerson Motor Installation and Maintenance Information manual states, “Sleeve bearing motors require periodic re-oiling. Re-oil continuous duty units once a year, intermittent duty units every two years, and occasional duty units every five years with 30 to 35 drops of SAE no.
