How to Maintain Your Evaporative Cooler

I work hard for you and your team – please look after me…

The best investment for regulating the temperature and air quality in your building is an evaporative air conditioner because it is affordable, delivers clean air, and has a low negative environmental impact.
Operating in a natural physical environment, they gather dirt, pollen, and wind-blown debris, which over time can accumulate and clog the unit. There are no prizes for figuring out that clogged filter pads and pump systems cause less airflow, increased operating expenses, and a higher likelihood of component failure – repairs are expensive.

Fixed evaporative units, like any natural system, require cleaning to function properly… A good rule of thumb is once or twice a year, ideally before the heat of the summer and around the halfway point… It is critical to keep up with maintenance…

So, what does maintenance entail?

Clean the tanks, and get the thanks…

The IDDAC-670 has an auto-cleaning function that bleeds out the water once every 8 hours by default, but the cleaning schedule can be set to any time between 2 and 72 hours.
The water tank, as well as the water in it, must be clean to ensure that the unit performs optimally and that the quality of air emitted by the evaporative cooler is not compromised.
The solution is to drain the tank and thoroughly rinse it with mild soapy water once a week before refilling it with fresh water. Ensure the water tank has enough water in it to keep it from running dry.
Don’t let your water tanks breed mosquitoes, germs, bacteria, and other harmful microorganisms.

Change the pads…

Replace the cooling pads on a regular basis and remove any mineral deposits with a wire brush and a mild soap and water solution. Because the pads will eventually break or become useless, it is critical to replace them as needed.

Clean the Outsides…

Wipe down the cooler’s exterior with a damp cloth and a little mild soap, avoiding harsh chemicals that could damage the paint.

Clean the Fans…

To keep the fan in good working order, wipe the fan blades with a damp cloth and lubricate the motor shaft once a year.


When transitioning to the cooler months perform the following hibernation routine on fixed units:

  • empty the tank
  • clean the entire system thoroughly
  • store the cooler in a dry, safe place

To summarise, caring for your evaporative air cooler system pays off handsomely – extended longevity and performance optimisation rely on it.
