ELECTRICAL SHOCK HAZARD
FIRE HAZARD
•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
ELECTRICAL SHOCK HAZARD
•Serious injury or death may
occur.
•Disconnect from electrical
supply before and during
assembly of this product.
This cooler comes equipped with a 120-volt

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.
ELECTRICAL SHOCK HAZARD
•Serious injury or death may
occur.
•Disconnect from electrical
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.

Page 10 of 16
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.
ELECTRICAL SHOCK HAZARD
•Serious injury or death may
occur.
•Disconnect from electrical

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.
