PREFACE
We really appreciate you credit and support in advance. Our evaporative air cooler will bring you
breeze health with least energy.
Adopting the most advanced evaporative cooling technology in the world and the contemporary
production management system, this installation manual is specific for KS2P-18C210 evaporative air
cooler. To ensure the optimal efficiency, we recommend you to read the manual carefully before use.
How evaporative cooling works?
Evaporation cooling is to cool and humidify air by water evaporation to absorb heat. Do you ever
wonder why you feel cooler by the ocean? It is because hot air is blown over water causing some of
the water to evaporate and absorb heat. Evaporative air cooler working this evaporation principle.
In an evaporative cooler a circulation pump keeps the cellulose filter pads fully soaked. As warm air
passes over wet filter pads water naturally evaporates into the air. The air is cooled as it gives up the
heat required to evaporate the water.
Application areas of evaporative air cooler
1. Relative dry and hot areas
Most of the areas which need to reduce temperature and increase ventilation can use our product,
such as mall, supermarket, office, hotel, Hospital, station, gymnasium, exhibition, restaurant, dancing
room, hall, school, factory.
2. Relative humid areas
Evaporative air cooler is also suitable for the high-temperature or peculiar smelly factories, such as
textile mill, dress mill, printing and dyeing mill, tannery, shoes mill, plastic mill, steel works, electronic
manufacture and chemical plant. You can use our cooler to full cooling. Our cooler is also suitable for
the fuggy areas such as game or disco parlor, kitchens, refectory or hotel, you can use the cooler to
cooling and vent.

Location of evaporative air cooler
Always make sure the unit is operated on a level surface. When using the cooler indoors, the best
location for it is near a partiallyopened windowor door where hot outdoor air can be drawn into the unit.
The Mobile Model is portable but use caution when rolling the unit to avoid splashing and spilling of
water. Cool air can best be directed through the space by using a partlyopened windowor door, ideally
one that is situated on the opposite side of the space from the cooler. This allows the cooled air to be
moved through the space and exhausted back outdoors which is critical to proper operation of the
cooler.
Our evaporative coolers features
1. Well designed system ensures best cooling effect;
2. Energy efficient and environmental friendly saving more than 80% of electricity as compare
with conventional compressor air conditioners;
3. The patented filter pad has over 90% of soak rate;
4. High quality sealed aluminum motor, with good sinking effect, IP44 high level protection,stable
temperature, water-proof and good appearance;
5. The exclusive fan blades produce large airflowand create little noise;
6. Filter pads are easy to clean and maintain;
7. Patented open-stylewater diffuser ensures high efficiency and stable water supply;
8. Multi-lever air flow regulator.

Check up and adjustment before operation:
1. Is the cooler installed horizontally?
2. Is drain pipe connected to the machine?
3. Is the water supply leaking?
4. Adjust water level in the sump?
5. Is the power supply connected correctly (particularly for three phase machine)?
6. Is the power line for the control panel correctly connected?
7. Is the operation current within the rated range?
8. Is there unwanted object in the vent?
9. Is the voltage correct?
10. Does cooler vibrates noticeably while operating?
11. Is there any foreign objects in the sump?
Important notes
1. The best effect is achieved when the unit is used in a well ventilated and dry place, where the unit
takes in 100% fresh air from outside and no re-circulation occurs.
2. Avoid discharging cool air into an closed space. There must be enough space for discharged air, even
use exhaust fans
3. For a place without powered exhaust, 0.8m²of exhaust area is needed for every 3600m³/h air
discharge. When using a powered exhaust, the designed exhaust volume shall not be less than 85%
of air intake.
4. Keep the unit away from welding sparks or any source of fire during the installation and when the unit
is running.
5. The unit must be tested and adjusted. E.g.: adjusting water level floats before operation. Ensure that
the unit is operating within the rated electrical currency.
6. Ensure correct wiring of the power and controller. The section in the power socket shall not be less
than 1.5mm². the units shall use a dedicated power line instead of sharing a power line with other
equipments.
7. Voltage of power supply shall be within 10% vibration from the rated voltage. Lower voltage may
cause motor start failure or undue frequent starts and stops. Long-term low voltage or high voltage will
cause damage to the motor.
8. The controller and its wire shall be kept away form strong electronic and magnetic interference, such
as frequency converter, silicon speed and temperature controller, high frequency heater circuit or high
power motor. Avoid wiring the power supply lines parallel to these sources. In the case of
unavoidability, the power line must maintain a distance of more than 30cm from parallel interference
source.

Packing and transportation
1. Packed in carton on wood pallet.
2. Keep dry and upright.
3. Do not pile more than 2 units.
4. Keep the unit vertical during transportation. The tilt angle shall be less than 60 degrees.
Operating Instructions
Installing the casters:
Locate the casters inside of the cooler and attach them to the cabinet bottom. Start all bolts into nuts before
tightening. The rigid casters mount at the front and the swivel casters mount at the back.
Connecting the water:
Move the cooler to an area where it can be filled with water and drained. The cooler should be located on
level ground. Connect to a water supply using a commercial grade garden hose connected to the adapter
on the float valve and turn on the water. Verify water tight connections by visually examining both the
float/hose connection and drain plug.
Turn on the water supply to the cooler. The hose connection to the float valve provides an automatic
method of refilling the water supply as water is evaporated.
For best results, turn the pump on a few minutes before turning on the blower fan. This allows the cooling
pads to pre-wet best efficiency.
Whenever possible operate the blower fan at low speed for maximum cooling. When cooling is not required
you can operate the unit as a fan only by turning on the blower fan and leaving the pump turned off.
The water can be adjusted by tightening of loosening the clamp that pinches the water supply tube. Adjust
the water flow clamp so that adequate water is supplied to the aspen pads without excess water splashing
out of the trough during normal operation.
