Setup
- Placement: Place the Arctic Air ULTRA PRO on a flat, stable, and level surface. Ensure there is adequate space around the unit for proper airflow.
- Fill Water Tank: Open the top fill water tank. Carefully pour clean, cool water into the tank until it reaches the MAX fill line. Do not overfill. For enhanced cooling, you may pre-chill the water or place the evaporative filter in a freezer before use (refer to image below).
- Connect Power: Plug the provided power adapter into the unit's power port, then plug the adapter into a standard electrical outlet.

Operating Instructions
Once set up, operating your Arctic Air ULTRA PRO is straightforward:
- Power On/Off: Press the power button on the control panel to turn the unit on or off. The unit will typically start on a low fan speed.
- Adjust Fan Speed: Press the fan speed button repeatedly to cycle through the three available fan speeds (low, medium, high). Select the speed that provides your desired level of cooling.
- Direct Airflow: Adjust the multi-directional air vent to direct the cool air towards your personal space.
- Hydro-Chill Technology: The unit draws in hot air, which then passes through the wet evaporative filter. As water evaporates from the filter, it cools and humidifies the air, which is then expelled by the fan. This process also helps to purify the air.

Maintenance
Regular maintenance ensures optimal performance and longevity of your Arctic Air ULTRA PRO.
- Water Tank Cleaning: Empty and clean the water tank regularly, especially if the unit will not be used for an extended period. Use a soft cloth and mild soap if necessary, then rinse thoroughly.
- Evaporative Filter Care: The evaporative filter should be cleaned periodically. Remove the filter and rinse it under cool water. Allow it to air dry completely before reinserting. Replace the filter every 3-6 months, or sooner depending on usage and water quality, to maintain optimal cooling and air purification.
- Exterior Cleaning: Wipe the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Storage: Before storing, ensure the water tank is empty and dry, and the filter is clean and dry. Store the unit in a cool, dry place.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not turn on. | No power supply; power adapter not connected properly. | Ensure the power adapter is securely plugged into both the unit and a working electrical outlet. |
| Air is not cool enough. | Water tank is empty; filter is dry or dirty; ambient humidity is too high. | Refill the water tank with cool water. Clean or replace the evaporative filter. Note that evaporative coolers are less effective in high humidity environments. |
| Water is leaking from the unit. | Water tank overfilled; unit is not on a level surface; filter not seated correctly. | Do not overfill the water tank beyond the MAX line. Ensure the unit is on a flat, level surface. Check that the evaporative filter is properly installed. |
| Unit is noisy. | Normal fan operation; unit vibrating on surface. | Some fan noise is normal, especially on higher settings. Ensure the unit is on a stable surface to minimize vibrations. |
