Carefully remove all packaging materials and retain for future storage/use. Make sure there is no residual foam left in any of the components. No tools will be required to assemble this evaporative cooler.

Place the cooler on a firm, level surface before proceeding. Before using the evaporative cooler for the first time, we recommend cleaning the tank with a solution of warm water and light detergent.

  1. Remove the water tank by turning the water tank knob counterclockwise 90 degrees.
  2. Fill the tank with clean water. Pay attention to the water level indicator located on the front of the cooler to avoid overfilling the tank. The approximate tank size of the NEC500SI00 is 1.5 gallons (5.5 liters).
  3. Replace the tank back onto the back of the unit. Turn the water tank knob clockwise 90°. This locks the water tank back into place.

The NEC500SI00 evaporative cooler includes an optional ice pack for added cooling.

  1. Place the ice pack in the freezer until frozen. Do not open the ice pack or ingest its contents.
  2. Put the ice pack into one of the water tank’s chambers.
  3. The ice pack is not necessary for operation, but will help enhance the cooling effect in higher temperatures.
  4. The ice pack will last approximately 4 hours before melting.


After the tank is filled with water, connect the evaporative cooler to a power outlet. The unit will beep twice, indicating that the power source is connected. The cooler will be in standby mode at this time.

  1. Press the ON/SPEED button to turn on the evaporative cooler.
  2. To adjust the fan speed, press ON/SPEED button again until your desired speed has been reached. The current fan speed will be indicated on the display panel. To turn the unit off and revert back to standby mode, press the OFF button.

Fan Speed Indicators:     

After the desired fan speed has been selected, press the COOLER/HUMIDIFIER button to activate the cooling/humidifying function. This powers the water pump, cools the air and adds moisture to your air at the same time. The blue cooling icon will also be visible on the display panel.

Please note that if the initial fan speed is set to 3, the unit will revert back to the second speed setting for 5 minutes. After 5 minutes, the unit will automatically switch to the third fan speed. This allows the cooling pad to absorb sufficient water for optimized cooling. The cooler will not revert back to other speeds if the initial fan speed was set to either 1 or 2.


The NEC500SI00 has 2 different automatic airflow modes. Setting the airflow mode is optional.

To set the airflow mode, press the MODE button.

Natural Mode – Indicated by the palm tree icon on the display panel, this setting will adjust the airflow speed between low, medium and high.
Sleep Mode – Indicated by the moon icon on the display panel, this setting will gradually lower the speed at different intervals, depending on the selected fan speed. If the fan speed is set to 3, the cooler will run for 30 minutes on high speed, 30 minutes on medium speed, and then continue to operate on low speed. If the fan speed is set to 2, the cooler will run for 30 minutes on medium speed and then continue to operate on low speed. If the fan speed is set to 1, the cooler will continuously run on low speed
  1. This evaporative cooler is equipped with a 7.5 hour programmable timer. To set the timer, press the TIMER button. Each press of this button will add 0.5 hours to the set time.
  2. The set time will be indicated in the middle of the display panel.
To activate the oscillation feature, press the SWING button. The fan head will automatically oscillate counterclockwise, which directs cool air into a cyclone for a more focused cooling effect.


The unit is equipped with a remote control. A CR2032 3V coin-type replacement battery is included for your convenience.

  1. To put the battery inside the remote control, insert a cell into the slot located on the back of the remote control and turn it as directed on the remote control.● The cells shall be disposed of properly, including keeping them away from children; and● Even used cells may cause injury.
  2. To use the remote control, aim it at the unit’s remote control receiver and select one of the functions on the remote control. The effective distance is about 24″.
  • ON/SPEED = Power ON and adjusts speed
  • OFF = Power OFF
  • TIMER = Timer function of up to 7.5 hours
  • SWING = Oscillating air louvers
  • COOLER/HUMIDIFIER = Controls cooling/humidification function

  1. If the water level in the tank drops below the minimum level, the unit will produce an audible alert that will last for 10 seconds. After 10 seconds, the evaporative cooler will automatically turn off.
  2. If the water tank is removed while the unit is on, it will automatically turn off.



Always unplug the evaporative cooler from the power supply before servicing or cleaning.

Regular cleaning and maintenance is an essential step in maintaining the longevity of your tower evaporative cooler and ensuring that it operates free of defects. Maintain your evaporative cooler by following these steps:

  1. Use a soft cloth and a mild soap and warm water solution to clean the unit’s exterior. Do not use harsh cleaners, gasoline, paint thinner, benzene, etc., as these substances can damage the evaporative cooler.
  2. Thoroughly dry all of the cooler’s parts with a soft cloth before reconnecting the unit to the power supply.

To prevent the cooling pad and filter from becoming clogged with dust, mineral deposits and other buildup, we recommend that it be cleaned at least once a month.

  1. Remove the dust filter from the back of the unit by pushing down on the two tabs located above the filter and pulling it out. Gently scrub it with a soft brush and rinse with water.
  2. While the dust filter is off, turn the knob on the pad clockwise and pull it out from the back of the unit. Rinse the pad with clean water to remove dust. For a more thorough cleaning, use a diluted vinegar solution to wash the pad. If necessary, immerse the pad in the diluted vinegar solution for 30 seconds to remove hard water buildup. Be sure to rinse the pad thoroughly with clear water to remove vinegar residue.
  3. Allow the filter and the cooling pad to air dry completely before replacing them in the unit.

The water tank should be emptied regularly to ensure hygienic use. To clean the tank, rinse it with warm water and a light detergent solution. Rinse with clean water and allow it to dry completely before placing it back into the cooler.


Hard water buildup can affect the performance of the cooler’s water pump. To prevent malfunctions, clean the pump and internal tubing with a calcium and lime cleaning product (such as CLR) at least once a season.

  1. Empty any water from the tank.
  2. Pour the cleaner into the water tank and close it. Be sure to push the tank in completely to ensure the water pump is lowered into the tank full of cleaner.
  3. With the tank closed, allow the pump to soak for 10 to 20 minutes.
  4. Remove the cooling pad from the back of the unit.
  5. Run the cooler for 30 seconds. This will circulate the cleaning solution through the pump and tubing to remove any leftover mineral deposits. Do not operate longer than 30 seconds, or damage might occur to other parts of the cooler
  6. Rinse the tank and fill it with clean water. Run it for several minutes without the cooling pad in place to ensure the cleaning solution has been rinsed away.
  7. Replace cooling pad and dust filer and operate unit as normal.
  8. If the evaporative cooler will not be in use for an extended period of time, place the unit back in its original carton and keep it stored in a clean, dry place.


Problem Possible Causes Solution
