Product: Evaporative Air Cooler
Type: HHB70
Using effective cooling pads as evaporator, this type of air cooler makes full use of the principle of evaporative cooling. As a
result, it can not only lower the temperature effectively, but also filter the dust particles in the air to improve the air quality.
Details about the cooling principle: Negative pressure is produced through the air draft by the fan. At the meantime, water
is transported by the water pump to the water distributor and it can wet the whole surface of the cooling pads. The special
angle of the cooling pads enable the water stream to flow to the side where hot air is absorbed.
A large amount of heat will be absorbed when the hot air passes the water-soaked cooling pads, resulting in the cooler,
moister and fresher air that will be sent out to the room since the temperature of the air is greatly lowered and the air itself
gets filtered. Then the unevaporated water drops to the bottom, forming the water cycle.
3. Applications
The HHB70 can be used in:
• Company offices,shops, hospitals, schools, workshops, workers dormitories, outdoor teahouse/coffee bars, restaurants,
recreation facilities.

6. Important reminders
Please read the manual carefully before operating the cooler.
Operating conditions:
1. Air supply must be largely free of dust or extra cleaning is required.
Protect the power cable from vehicle or foot traffic.
Connection to incorrect electric voltage, or faulty installation, will cause danger of electric shock.
Other tips for cooler use:
1. Keep doors and windows open to allow fresh air to enter, and treated air to exit when cooler is operating.
2. Flashing red light on the control panel means water level in reservoir is low.
3. Rinse the reservoir with fresh water and clean prior to use after a period when the cooler is not being used.
4. Take care when moving the cooler, especially when it is full of water. Pushing too hard will cause the cooler to
overbalance and tip over, which may cause injury and will damage the cooler.
5. To prevent build-up of algae and other biological organisms in the reservoir, regularly add chlorine/bromine tablets as
per tablet manufacturer recommendation for evaporative cooler reservoirs.

The fan blades will swing from the left side to the right side and the
wind swing pattern will light up when the wind direction button is
pressed. Repress the button to stop the swing.
WIND TYPE
Press the wind type button to change the wind type between the
standard wind , the natural wind and the sleeping wind. The corres-
ponding pattern will display on the screen.
Standard Wind: The wind type will not change once one particular
wind type is chosen.
Natural Wind: The wind speed will change randomly among high,
medium and low.
Sleeping Wind: When the wind type is changed to sleeping wind when
the operating wind speed is high, the wind speed will automatically
change to medium wind after half an hour.
Then the wind speed will automatically change to low wind after
working in the state of medium wind for another half an hour and will
maintain in the state of low wind as long as no further instruction is
made.
ANION
Press the anion button to release anions. The anion pattern lights up at
the same time.
TIMER
The timing function will be started and the timer pattern will light up
when the timer button is pressed. Press the button continuously to

8. Installation and use
1. Open the packing box and take out the air cooler.
2. Add water: Open the water-adding hole on the left side of the air cooler (press it
to open) and add water to thewater tank. Control the amount of water added by observing the water level
display and pay attention to the following three points:
• Don’t splash water onto the motor or its surrounding area lest the electrical
apparatus elements will be damaged.
• Add no more water when the water level reaches “MAX’’, or the extra water
will spill from the air cooler.
• Please use clean tap water.
3. Connect the air cooler to the power source to enter the standby mode. Press the on/off button to start the
machine and press different buttons to set the desired wind speed, wind type, wind direction and to use any
other function.
4. When the air cooler is in operation, you can press the on/off button to stop it and return to the standby mode.
5. You can also use the remote control to operate the machine. The function of the remote control is the same as
the control panel.

batteries.
2. When you are using the remote control, please direct it to the control panel. The effective remote
control distance is 10 meters.
3. There is a place on the top of the machine where you can place the remote control in case it will fall
down.
9. Precautions for use
1. The water level of the water tank mustn’t go over the “MAX” scale at any time. When the air cooler is in the state of
cooling,don’t let the water level go below the“MIN” scale.
2. When the environmental temperature is too high, it’s better to choose the cooling function because it can not only lower
the temperature but also add moisture to the air.
3. After adding water to the air cooler, avoid incline and collision when the machine is being positioned or moved so as not
to spill the water.Turnover of the machine is forbidden so as to avoid accident.
4. Other objects (other than the remote control) are not allowed to be put on the air cooler. The air outlet is forbidden to be
covered and obstacles mustn’t be positioned within one meter of the machine’s front and back.
5. If the “Cooling” function is turned on when there is no water in the water tank, the water pump will not work.
6. Please pull the power plug and cut off the electricity before any cleaning or maintenance is done.
7. When you are cleaning the machine appearance, please use wet cloth (or wet cloth with some cleanser essence). Don’t
use any corrosive cleanser essence to clean the machine. Also drip washing and rinsing are strictly prohibited.
8. If the machine topples with water inside, pull the power plug immediately. The air cooler can’t be turned on again before
it is completely dried,or the machine may be damaged.
9. The back of the machine can’t be positioned near the wall or curtain, or the airflow will be blocked and the effect will be
badly influenced.
10. Don’t shake or knock on the machine forcibly when the air cooler is in use, or the machine will stop working
automatically and have to be turned on again.
