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. Instruccions de funcionament
The Hessaire M150 features an easy-to-operate mechanical control panel located on the top of the unit.
6.1 Tauler de control acabatview
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.
