1. Forward

Thank you for choosing this evaporative air cooler. The cooler you purchased may look slightly different from the illustrations, but the operation is the same. For safe and correct use, please read this manual carefully and keep it for future reference.

2. Precautions

  • Read this manual carefully and keep it for future use.
  • This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction.
  • Children must be supervised and must not play with the appliance.
  • Make sure the fan is switched off and disconnected from the mains before removing any guard or panel.
  • Unplug the cooler during filling, draining and cleaning.
  • If the supply cord is damaged, it must be replaced by a qualified service agent.
  • Keep the cooler away from any source of fire or open flame.
  • The earth wire must be at least 1.5 mm² for safe grounding.
  • The supply voltage should be within ±10 percent of the rated voltage. Continuous operation at too high or too low voltage can damage the cooler.

3. Working Principle

The evaporative air cooler lowers air temperature using water evaporation. A circulating pump draws water from the tank and distributes it evenly over the cooling pads. Warm air passes through the wet pads. The water evaporates and absorbs heat from the air, which reduces the temperature. The result is fresh, cool air.

4. Application Areas

  • Rooms or areas at home where cooling is needed.
  • Outdoor dining areas that need cooler air.
  • Open shops, supermarkets, restaurants, bars and similar places.
  • Outdoor events and activities where temporary cooling is required.

5. Control Panel and Remote

Operation panel and remote controller

The control panel includes indicators for temperature display, timer, cool mode, water shortage, fan speed, sleep wind, natural wind and remote control receiving.

6. Operation Instructions

6.1 ON / OFF

  • When power is connected, the buzzer sounds once and the cooler is in standby with all indicators off.
  • Press ON/OFF:
