FAQs

Can I use this unit indoors?

Yes, it is designed for indoor and semi-outdoor use, provided the room has sufficient ventilation like an open window or door.

Does this unit require a window kit?

No, unlike portable air conditioners, evaporative coolers do not need a vent hose, but they do require airflow to be effective.

How often should I clean the honeycomb pads?

Depending on water quality and usage, it is recommended to check and clean the pads every few weeks to prevent mineral deposits.

Does it lower the room temperature?

Yes, it lowers air temperature through the natural process of water evaporation, which is most effective in hot, dry environments.

What happens when the water runs out?

The unit features a low-water cut-off safety feature that automatically shuts off the cooling pump to prevent damage to the motor.

Troubleshooting

Unit is not cooling effectively

Ensure the water tank is filled and the pump is active. Check that the room has adequate ventilation; evaporative coolers require fresh air to function.

Water leakage from the base

Check the drain plug to ensure it is tightly sealed. Verify that the unit is on a level surface and the overflow pipe is unobstructed.

Fan runs but no air movement

Ensure the front louvres are not obstructed and the fan speed is properly set on the control panel.

Pros and Cons

Pros

  • High cooling capacity suitable for large commercial spaces
  • Flexible water source options including a 48L tank or continuous hose connection
  • Durable construction designed for demanding environments
  • Simple, intuitive control panel for easy operation
  • Built-in safety features like low water cut-off

Cons

  • Requires proper ventilation to avoid high humidity levels
  • Relies on water evaporation, meaning it is less effective in high-humidity climates
  • Not a true air conditioner; it does not lower ambient temperature via compressor cooling
  • Bulky design may be difficult to maneuver in tight spaces

Setup, Compatibility & Care

Setup is straightforward: position the unit on a level surface, ensure the caster wheels are locked, and fill the 48-litre tank with clean water or connect a garden hose to the continuous supply valve. Always ensure the unit has at least 50cm of clearance from walls to maintain optimal airflow.

Care Instructions:

  • Periodic Cleaning: Regularly remove and clean the honeycomb pads to prevent mineral build-up and mold growth.
  • Tank Maintenance: Drain the water tank completely if the unit will not be used for an extended period to prevent stagnant water.
  • Storage: Store the unit in a dry, covered area during the off-season, ensuring the filter pads are completely dry before packing away.
