• Serious injury or death may

occur. • Do not use in locations

containing hazardous or explosive atmospheres.

• Do not use outdoors in wet

conditions and in unprotected locations.

This unit is a compact, self-contained, high-efficiency portable evaporative cooler capable of lowering existing temperatures by as much as 26 degrees. The unit draws air across water-saturated high-efficiency cooling pads, causing a gradual evaporation of the water, thereby removing heat from the air. The 10-gallon reservoir provides hours of operation without a water supply. Evaporative cooling is also environmentally friendly, since it does not use chlorofluorocarbons (CFC’s), and therefore does not contribute to ozone depletion.

To understand how the portable evaporative cooler works a basic understanding of psychrometrics is necessary. Psychrometrics is the branch of thermodynamics devoted to the study of air and water vapor mixtures. The psychrometric chart is a graphical representation of properties of moist air. To illustrate how the unit operates, some of the relevant properties are described in this section followed by a sample application.

Dry-bulb temperature is measured with a thermometer. Dry-bulb temperature lines on the psychrometric chart are the vertical lines. The wet bulb temperature is the lowest temperature that can be reached by evaporating water into the air.

Dew-point temperature is the temperature to which a given sample of air must be cooled so that moisture will start condensing out of it. When air is saturated, the dry-bulb, wet-bulb, and dew-point temperatures will all be equal. The horizontal lines show the dew-point temperature on the psychrometric chart.

Relative humidity is the amount of moisture in the air relative to the amount of moisture the air would hold if saturated at that dry-bulb temperature. Percent humidity is not the same as relative humidity and is not used in HVAC design. This graph shows the relative humidity curves on the psychrometric chart.

Inspect your unit for any concealed shipping damage and report it immediately to your carrier. In addition to our evaporative cooler the following items are included in a hardware pack and will need to be installed before operating the unit.

UNPACKING

Non-Swivel w/ lock (qty. 2)

The following example illustrates the use of the psychrometric chart as it relates to evaporative cooling. Since all of the items described above are properties, any two of them describe a state point on the psychrometric chart. Once this point is determined, the values of all the other properties can be read from the chart. The example below shows a Mollier type psychrometric chart for atmospheric pressure. The dot shown is a state point and the following properties are known about the air/water mixture at this state.

Take the air/water mixture described by the state point above, with a dry-bulb temperature of 97° and 43% relative humidity, for example. As the air passes through the cooling media on the unit, moisture is added to the air increasing the relative humidity. This increase in relative humidity brings a decrease in dry bulb temperature. When the relative humidity is raised to 70%, the dry bulb temperature has dropped to 86°F. When the humidity level approaches 100%, the dry bulb temperature has dropped nearly 20°F to 78°F.

Garden hose connection: This unit comes equipped with pressure regulator a female garden hose adapter that can be connected to any standard garden hose. The float will automatically maintain the correct water level. DO NOT over tighten as this may cause the float assembly to rotate resulting in over filling of reservoir. Stand-alone: This unit can also be manually filled and moved into position. To fill the unit; simply remove the fill cap located on the side of the housing, fill with water, and replace the cap. NOTE: Do not fill the reservoir past the max water line. Water can easily spill from inside the unit when rolling the cooler on uneven surfaces or if the reservoir is overfilled.

-Do not connect this unit to any water source where the water pressure exceeds 60 psi. This will cause permanent damage to the unit. Pressures above 60 psi must use a pressure regulator. A pressure reducing valve is installed on the float inlet. -Do not fill the reservoir past the MAX water level line indicator.

CONNECTING THE WATER SUPPLY




supply before and during assembly of this product.

This cooler comes equipped with a 120-volt power supply cord and should only be plugged into a 120 VAC, 60 Hz branch circuit that includes a properly sized over current protection device (fuse or circuit breaker). Consult a licensed electrician if there is a question about adequacy of the electrical supply. EXTENSION CORDS Use only 3-conductor extension cords of 14AWG to 25 ft., 12AWG to 50 ft. & 10AWG to 100ft. length maximum. Do not use the extension cord powering this cooler to power any other appliances or electrical loads.

CONNECTING THE ELECTRICAL SUPPLY



• Make certain the power

source conforms to specifications on data label.

• Do not connect plug to power

supply without cooling pads installed and fastened in place.

Initial start-up:

Clean out the Sump: Remove any foreign material in the sump before start up. It is normal for some debris to accumulate in the sump. It is best to flush out the sump with water to clear any debris.

Filling the unit with water: Once the unit has been hooked up to a water source, turn the water supply valve on and the unit will fill with water. The float valve will shut off the water flow when the reservoir is filled.

START-UP PROCEDURE

Do not operate the pump when the reservoir is dry. This will cause the pump to fail and also void the warranty.

There are 4 factors to consider when determining where to place your evaporative cooler.

1. Fresh air supply: The inlet side of the unit (pad side) requires a constant, uninterrupted supply of fresh air for maximum performance. A distance of 3 ft. of clear space is recommended.

2. Discharge airflow: The cool air discharged from the unit should be free of obstruction to allow the air to

circulate in order to maximize the cooling zone.

3. Ventilation: Allow cooled air to circulate away from discharge area of cooler. This ensures that the unit does not re-circulate air that has already been through the evaporative cooling process.

4. Placement: The unit must be placed on a level surface to operate correctly. The units create an oval shaped

air pattern that can reach out as far as 20 feet. Obstacles such as racks and workbenches may interfere with the cooling zone. An attempt should be made to locate the unit in such a manner that interruption of the air pattern is held to a minimum. Multiple units may be required to cover large areas.




supply before servicing this product.

Annual start-up: At the beginning of each cooling season follow the same procedures as the initial start-up with some possible exceptions. If the media was removed for the winter, it will have to be replaced (note instructions below on media replacement). Check the condition of the media. If the flutes of the media are clogged with buildup of alkali deposits or are otherwise damaged, consider replacing the media. This is the best time to make this decision while the unit is not being used and may not be as critically needed.

Starting the pump: Allow the reservoir to fill before turning the pump on. Once the reservoir is full, the pump switch may be turned to the ‘ON’ position.

Initial Washing of the Cooling Media: The media should be washed for several hours by running the pump without any airflow through the media. This washing action will clean out any debris in the media as well as reduce any odor and improve wetting ability.

Break in Period for Cooling Media: The media will reach its peak operating condition after about 100 hours of operation. The chemical constituency rigidifying agents in the media will then be set and will not leach out further. Ignore any coloration in the water during this initial period.

If a strong odor persists, run the pump to flush the media with water, without airflow through the media, until the odor disappears.

ODOR CONTROL

One of the few inconvenient aspects of evaporative cooling is the control of unpleasant odors. There are two primary causes of these odors:

1. Initial wetting of new pads 2. Poor maintenance and storage behaviors and/or poor quality water.

Your EVAP-series cooler has been delivered with pads that have never been wet. The same is true of replacement pads. The resins and adhesives used to create these pads will give off an odor during initial use that can last for a week or more. This can’t be avoided but it can be minimized. As the cooler is used over time, algae and bacteria growth can occur. This can also be minimized. Below are recommended actions to be taken to address noticeable odor due to the above causes.

Odor from Initial Wetting of Pads

1. At first use of your new cooler or after installing new replacement pads, make certain there is lots of fresh air available to the cooler.

2. Add one capful of liquid laundry fabric

softener to the water in the bottom reservoir of the cooler.

3. The odor from initial wetting of pads

should disappear in approx. two weeks of operation.

4. If odor does not disappear after two

weeks of operation, follow the steps for “Periodic Odor Maintenance”.

Periodic Odor Maintenance

1. Make certain the cooler is full of fresh water.

2. Flush the pads for 3 – 4 hours by

operating the pump only with the fan off. Adjust flow control valve for maximum rate of recirculating water flow.

3. After flushing, empty the reservoir

through the front drain and clean out any residual particulate in the reservoir.

4. Refill reservoir with fresh water and

proceed to use the cooler.

5. Repeat the above steps as necessary to eliminate odor.

MAINTENANCE

Algae/Bacterial Control Control with chemicals. Chlorine is the most commonly used chemical to control organisms. It is potentially dangerous and should be used with great caution. One of the best methods to introduce chlorine into the water circulation system is on the pressure side of the pump on a continual or timed basis. Note: Consult water treatment experts before attempting chemical water treatment. Neither media manufacturers’ nor equipment manufacturers’ warranties cover damage due to chemical water treatment and warranty may be voided when chemicals are used. Other chemicals suitable for organism control include hydrogen peroxide, bromine based oxidizers, and other commercial products. It is important to maintain a 6 to 9 pH level after treatment. Control without chemicals. With water, sunlight, and nutrients, most organisms can survive. The water in the media can be allowed to dry out and any organisms living in the media will become dry and flaky. This can then be flushed out at the next start up of the unit. Shading the media will prevent the sunlight from encouraging the growth of organisms. Nutrients are available from the air itself, however in some instances, phosphates and fertilizers are carried in the air stream and should be avoided. Flushing the media with fresh water and dumping the sump water periodically is the best preventative measure that can be taken. This flush and dump action will actually prevent alkali deposits and algae/bacteria from growing. There are also some non-recirculating water distribution systems available that provide a constant flushing/dumping action.

Water Chemistry Hard water contains relatively large amounts of minerals, primarily calcium. A sample of water can contain only a specific maximum amount of dissolved solids in solution. If these concentrations increase beyond a certain level, the excess minerals precipitate out as a solid material. This precipitation will appear as the familiar white residue left on the face of the media. It is commonly referred to as alkali, calcium depositions or salts. The same process occurs in the desert when water collects in depressions and since only pure water evaporates the minerals are left behind. These are commonly referred to as “dry lakes” or “salt flats”. The build up of these minerals on the face of the media does not because a problem until the airflow is restricted. There is no easy way to remove these deposits. The best solution to this problem is preventive rather than corrective action and usually requires simple actions such as media flushing with fresh water and periodic dumping of the sump water. Soft water is on the opposite side of the scale for water chemistry as compared to hard water. Basically, removing or diluting the effects of the calcium in the water creates soft water. Soft water is not to be confused with pure water. Pure water does not contain or contains very small amounts of minerals found in either hard or soft water. While hard water can leave deposits in the media, soft water can cause harm to the media by leaching out the rigidifying agents. Either water condition can have some adverse effects on the media. PH Range. A pH range of 6 to 9 is the acceptable range for the media, the closer to the center the better. The re-circulating system of the water distribution allows the mineral content in the sump water to become more and more intensive because the same water is re-circulating. The pure water is lost to evaporation while the minerals just continue to build up. TDS is the abbreviation for “Total Dissolved Solids” and represents, as the name implies, a way of identifying a measurement of the mineral content.

Removing the cooling media: In order to perform any maintenance on internal components the cooling pads must be removed to access the inside of the unit. Media removal / replacement is simple, if you follow these instructions! The media is soft when wet so be very careful when handling. The media has two separate flute angles, which are transverse to each other and alternate across the face of the media. One flute is 45° and the other is 15°. The alignment of the flute arrangement in relation to the direction of airflow is critically important. The 45° flute must be aligned upwards in the direction of the airflow. The 15° flute must be aligned downwards in the direction of the airflow.

1. Using a 5/16” nut driver, remove the (2) screws holding the pad retainer bracket in place. Save all hardware.

2. The pad may be tilted out of the unit and lifted out of the drain tray.

Note: Reinstall pads correctly; refer to sides of pad material for airflow direction.

To keep your unit operating at peak efficiency, ensure that the cooling pads are kept clean and dust-free. Dust and other particles have an adverse effect on the media’s ability to introduce water into the air stream. If the pad surface becomes dirty or dusty, clean with a soft brush and water. Daily maintenance: At start-up: It is best to run the pump several minutes before the fan is started to clean out any debris on the media. At shut-down: When shutting down your evaporative cooler at the end of each workday, the pump should be turned off approximately 15 minutes before the fan is turned off. This will allow the pads to drain and dry out. This simple guideline will ensure long and efficient pad life as well as help to control mildew and bacteria growth. Periodic maintenance: Depending on how often the unit operates, this procedure should be performed anywhere from every week for heavy use to monthly for light use.

1. Drain reservoir. 2. Remove cooling pads. 3. Clean out reservoir with either a towel or wet/dry

vacuum. 4. Reinstall pads and pad retainers.





Annual shutdown / Storage: 1. Wash down the media to flush out all the debris. 2. Open the drain in the sump to drain out any

standing water. 3. Wash the interior of the unit to remove any

algae or micro-organisms as well as calcium deposits. A weak dilution of muriatic acid will help clean the alkali (calcium) deposits. Commercial chlorine will kill and clean out the algae.

4. Store the unit in a dry area and cover if possible to prevent dust build-up.
