Ⅰ、Product Introduction
Evaporative air cooler is a kind of modern energy-saving product which is developed
through years of research and experiments. It has the following advantages:
1. Energy-saving: Up to 80% or more while comparing with traditional air-conditioner
2. Environmentally friendly: No use of refrigerants to create the cooling effect.
3. Efficient: Low electrical usage comparable to an exhaust fan but with cooling effect.
Its working principle is a "direct evaporative" humidification and cooling technology,
which not only has a cooling function but also can achieve air humidification.
Continuously circulating pump draws water from the water tank, and then the water is
distributed to the cooling pads. When the hot air enters into the cooling pads,
evaporation of water in the pads occur cooling the hot air before it enters the greenhouse.

Ⅲ、Range of Application
As the remarkable advantages of evaporative air cooler in cooling, humidification,
cleanness, energy-saving and ventilation, it is used in ventilating and cooling many
places like greenhouses, shops, homes, livestock barns, warehouses, etc.

V、Operating Instruction
1. The operating instruction of control panel (Picture 1)
（1）ON/OFF
Plug cooler in, and press this button to turn on the air cooler. During the initial use,
the default setting is in the “cool mode”. Press button again to cut the unit off (turns
off fan motor, pump and display).
（2）COOL/FAN
Press this button to select COOL mode (fan and water pump are both on) or FAN mode
(only fan is on). The lights on the control panel will indicate which mode the cooler is
in.
The COOL light will light up, after 30 seconds, fan motor will start working.
（3）Speed
Press this button to adjust the fan speed. Choose from low, medium and high.
（4）Swing
Press this button to make the louvers oscillate left and right.
（5）Clean
This button is not used or needed on this model.

3. Audible alerts
(1) Each time you press a button on the remote, a buzzer will ring. The operation of
remote control is the same as control panel.
(2) When the water level is below the warning level, the water pump will stop running
and the buzzer will ring, and it will return to work after water is added.

VI、Installing and Using Instruction
1. The unit must be installed outside or in the area with enough return air volume and
0.15~0.6 m/pa water pressure.
2. The unit for open area using, if it working in closed area, must open the vent to keep
balance between the air input and displacement.
3. Before installing the air cooler support in the outside wall, draw a horizontal line with
level ruler firstly to keep the support level, controller put higher 2m than floor, support
welding and installing must be stable, which can bear no less than 200 kg of dynamic
load, and then put the item on the support. If higher 3m than floor, adding barrier.
Lastly connect the PVC pipe with speed glue to keep smooth for water inlet and outlet.

4. Operation and maintenance
（1）In high humidity season, it is better to choose wind mode as there is humidifying
effect in cool mode.
（2）After adding water, do not let machine tilt, collide, laid or move to any position that
will make the water overflow. Do not overturn the machine.
（3）Do not cover the air outlet, a clear space of at least 3 feet should be provided in
front of the air outlet and around the cooling pads.
（4）Please remember to unplug the machine before cleaning or maintenance.
（5）Clean the shell with a wet rag. Don`t flush it with water directly.
（6）If the machine is overturned with water in it, pull the power plug immediately. You
should only re-start the machine after it thoroughly dries out, otherwise, it may
malfunction.

（7）Don’t keep the air outlet close to walls or window curtains cause the air will be
blocked.
（8）If the machine is not in use, please pull the power plug.

Ⅷ、Maintenance Instruction
Turn the power off before maintenance or repair of the machine so as to prevent
accidents due to illegal operation. To ensure the cooling effect of the machine, the
machine body should be cleaned by water every day or every week. The interior of the
machine shall be also cleaned regularly, and the proper cleaning interval is one month;
however, the actual cleaning time will vary depending on the exterior environment.
1. Instructions for cleaning the interior of the air cooler
(1) Turn off the power and loosen the fix screw and remove the air inlet shutter together
with the evaporation heat exchanger, use a soft brush to clean it.
(2) Clear away the deposit in the chassis with water.
(3) After cleaning, install the air inlet shutter (together with the evaporative heat
exchanger), and tighten the fixing screw.
Attention: during cleaning, the pressure of the water should not be too high. When
cleaning the wet curtain, please don`t use acidic or alkaline detergents.
2. It is suggested that cooler be inspected and maintained annual to maximize the life
of the unit.
