9. ese two models require assembly before operating See page A l for assembly information B Removing the cooling media Disconnect air source Caution Disconnect air supply before performing this operation The PORT A COOL unit should now be exposed to allow removal of the cooling media pads On the 36 and 24 model the front flap and the pad screen if installed 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 The two pads to either side of the center pad may then be removed in the same manner Should you desire to remove the two outside pads they must first be pulled sideways toward the center of the PORT A COOL unit until they clear the side retainer They may then be removed as the other pads C Connecting the water and compressed air Water Connection PORT A COOL unit must be upright and sitting on a stable surface After the PORT A COOL unit has been thoroughly tested at the factory the special female female adapter is connected to the brass bulkhead connector on the left side of the PORT A COOL unit when looking at the fan side Simply attach a standard garden hose to the brass female female adapter Verify that the rubber hose washer is in place before attaching and tighten the fitting to guarantee that a secure connection is made Once the hose connection is made water may be turned on to the POR
10. ious in that 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 operating Although this might seem a bit over simplified this particular problem may be caused by several things So while defining the problem a careful check of all systems should be made to fully understand the extent of the problem If you are having difficulty determining the exact problem it is best to contact the distribu tor from whom the PORT A COOL unit unit was purchased The distributors are fac tory trained and will be able to have your PORT A COOL unit unit repaired quickly V REPLACEMENT PARTS Warranty Replacement Parts Replacement parts may be acquired from the distributor from which you purchased the PORT A COOL unit If you are not certain from whom the PORT A COOL unit was purchased please call the Port A Cool LLC Technical Support Hot Line 888 266 5243 or email Tech Support at support port a cool com and have the serial number of your unit ready The serial number will help us determine whom the appropriate distributor is the model of PORT A COOL unit and how best to locate the required parts Non Warranty Replacement Parts Again replacement parts should be ordered from the distributor from which you pur chased the PORT A COOL unit If you are unable to acquire the necessary parts please call the Technical
11. lding all the moisture it can If the air has a low relative humidity when entering the PORT A COOL unit then it has the ability to hold more moisture and will thus evaporate more water and cool more effectively When describing the amount of moisture in the air the term relative humidity is used because the sponginess of air changes relative to air temperature The warmer the air the more spongy it becomes and the more water it can hold That is to say that air that has a 100 relative humidity can hold no more water vapor However if the air is heated it expands and as a result the relative humidity decreases even though the total amount of water vapor in the air has not changed As a result we must describe the level of humid ity relative to the condition of the sponge we are talking about Is it a 50 F sponge or an 80 F sponge An 80 F sponge will hold more water at 50 humidity than a 50 F sponge How is cooling produced In order to evaporate water heat energy is required In fact the evaporation of one gallon of water requires almost 8 700 BTU s of heat Where does this heat come from From whatever the water is in contact with as it evaporates This could be a hot sidewalk your body a tree from the air itself or a wet cooling pad As the heat is removed from an object the temperature of that object is decreased in this case the air It is important to realize that the temperature of the water does not have a g
12. low an evaporative cooler to work well Since any evaporative cooling device must evaporate water to achieve cooling more water vapor is put into the air As the ambient relative humidity increases it becomes more difficult to put moisture into the air The efficiency of any evaporative cooling device is directly related to its ability to evaporate water cool at a given relative humid ity A unit with low efficiency will cool only at low relative humidity levels while a unit with high efficiency can achieve effective cooling at much higher humidity levels 8 www sylvane com 1 800 934 9194 C Evaporative Cooling and the PORT A COOL unit The PORT A COOL unit is the state of the art high efficiency portable evaporative cooling device High Efficiency rigid cooling media coupled with a unique patented housing design allows the PORT A COOL unit to cool effectively in very high relative humidity conditions Conditions that no other portable evaporative cooling device such as the old style swamp cooler could possibly approach The public has an initial tendency to equate the PORT A COOL unit with the swamp cooler and in reality the only thing that they have in common is that they are both evap orative coolers much as the 73 model automobile and 96 model automobile are both cars The key to efficient evaporative cooling is using a specially designed high efficiency rigid cooling media contained in a properly designe
13. ndition of having a few vertical dry streaks in the pads indicates that the supply of water is sufficient to the pads without being extreme When turning the unit off at the end of the day or week the pump should be turned off about 15 minutes before the air movement system to allow the cooling pads to dry This will enhance the life of the pads www sylvane com 1 800 934 9194 III MAINTENANCE STORAGE Very little maintenance is actually required on the PORT A COOL unit Most of the maintenance on the PORT A COOL unit is cleanliness Keeping the PORT A COOL unit clean will do more than any other single item to keep your new 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 of the PORT A COOL unit A Daily Maintenance Daily maintenance is really more an operational consideration than actual maintenance On a daily basis the pump should be turned off approximately 15 minutes before the fan is turned off This will allow the cooling pads to dry out and help extend their life help ing to control the growth of mildew mold bacteria and other odor causing elements B Weekly Maintenance At the end of the week or at a scheduled time the unit should be shut down and the sump tank should be drained On the 36 and 24 inch models this is accomplished by closing the Spray Bar Adjustment V
14. rease or decrease in the ability of the air to contain water vapor If the temperature increases without an increase in the pressure the result is a decrease in the relative humidity and thus an increase in its ability to hold more moisture That is to say that in the morning the humidity may be high but as the day passes and the tem perature increases the relative humidity will naturally decrease The extent to which relative humidity decreases through the day can be affected by local weather systems and proximity to large bodies of water If an increase in temperature accompanied by a weather system containing moisture moves in the drop in humidity will not be as great Nevertheless the fact remains that relative humidity does drop as air temperature increases In fact for every 20 F rise in temperature the moisture holding ability of air doubles For instance if the temperature of the air was 70 F and the relative humidity was 100 at 5 a m and the temperature increased to 90 F at noon the mois ture holding ability of the air would double As a result the air would now be holding only half of the moisture it is capable of holding 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 al
15. reat effect upon the cooling produced through the evaporation If you were to place a gallon of 50 F water on a warm sidewalk it would produce 9 000 BTU s of cooling by consuming the heat to perform the evaporation A gallon of 90 F water would produce 8 700 BTU s of cooling only a three percent difference After all if you were sprayed with water at either of these temperatures on a hot day you would still feel much cooler www sylvane com 1 800 934 9194 The following table demonstrates the BTU s removed from the air based on a given amount of water consumed in an hour by the PORT A COOL unit U S Gallons Hour Total BTU s Removed 10 37 8 liters or 8 3 Imperial Gallons 87 000 12 45 4 liters or 10 0 Imperial Gallons 104 400 14 53 0 liters or 11 7 Imperial Gallons 121 800 In simple terms evaporative cooling is nature s way of cooling The PORT A COOL unit utilizes the same phenomenon but in the most efficient manner possible B Humidity and Evaporative Cooling A cubic 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 ne 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 pressure results in an inc
