5.2 Positioning for Optimal Performance
For the most effective cooling, position your Hessaire M150 in front of an open window or door. It is crucial to also have another open window or door through which the humidified air can exhaust from the room. This creates a cross-ventilation effect, allowing fresh, dry air to enter and humid air to exit, maximizing the evaporative cooling process.
6. Awọn ilana Iṣiṣẹ
The Hessaire M150 features an easy-to-operate mechanical control panel located on the top of the unit.
6.1 Iṣakoso igbimo Loriview
The control panel consists of rotary switches for intuitive operation:
- Motor Speed Dial: Turn this dial to power on the cooler and select your desired fan speed: Low, Medium, or High.
- Pump Switch: Turn the pump switch ON to activate the water pump, which saturates the internal Xel50 Cooling Media. For fan-only operation, ensure the pump switch is OFF.
- Air Swing Delivery System (Oscillation) Switch: Turn this switch ON or OFF for automatic oscillation of the internal fan. This feature helps distribute cool air more evenly across a wider area.
The unit can be used in fan-only mode by keeping the pump switch off. This is useful for circulating air without adding humidity.
7. Itọju
Regular maintenance ensures optimal performance and longevity of your evaporative cooler.
7.1 Filter Cleaning
Ensure the cooling media (filter) is kept clean throughout the summer season. A dirty filter can reduce cooling efficiency and airflow.

7.2 Daily Operation Tips
At the end of each day of use, run your cooler on FAN NIKAN for 30 minutes. This helps to dry out the cooling media, preventing mold and mildew growth and extending its lifespan.
7.3 Winter Ibi ipamọ
Before storing your cooler away for the winter season, perform the following steps:
- Drain the water tank completely and wipe it clean to remove any residue.
- Clean the cooling media thoroughly.
- Reassemble the unit and run it on FAN NIKAN for 30 minutes to ensure the cooling media is completely dry before storage.
