5.2 Filling the Water Tank
The water tank has a capacity of 22 liters. Use the icy water inlet to fill the tank. Monitor the water level indicator to ensure it does not exceed the maximum fill line. When the water level is low, the empty water tank alarm will sound, and the pump will stop to prevent damage.
5.3 Airflow and Cooling
The cooler uses a powerful blower to deliver air up to 30 feet. The i-Pure Technology, combined with the honeycomb pad and dust filter, ensures that the air circulated is clean and fresh. For effective cooling, ensure there is adequate cross-ventilation in the room.
6. Maintenance and Care
Regular maintenance ensures optimal performance and longevity of your Symphony Diet 22i Air Cooler.
- Cleaning the Exterior: Wipe the exterior surfaces with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Draining the Water Tank: Regularly drain the water tank, especially if the cooler will not be used for an extended period. Use the water drain valve at the back of the unit. This prevents stagnant water and odor.
- Cleaning Filters and Pads: The dust filter and honeycomb pads should be cleaned periodically. Refer to Figure 3 for the location of the dust pre-filters. Gently remove and rinse them under running water. Ensure they are dry before re-installing.
- Mosquito Net: Inspect and clean the mosquito net as needed to maintain airflow and hygiene.
