Setup and Installation
- Unpacking: Carefully remove the air cooler from its packaging. Inspect the unit for any signs of damage. Retain the packaging for future storage or transport.
- Attaching Castors: The unit comes with 4 castors. Insert each castor firmly into the designated slots at the bottom of the air cooler until it clicks into place. Ensure all castors are securely attached for stable movement.
- Placement: Position the air cooler on a flat, stable surface. For optimal performance, place the unit near an open window or door to allow for cross-ventilation. Evaporative coolers require a source of fresh air and an exhaust for humid air to operate effectively.
- Filling the Water Tank: Locate the water inlet. Slowly pour clean, cool water into the tank. The water level indicator on the front of the unit will show the current water level. Do not exceed the 'MAX' fill line. The tank capacity is 12 liters.
- Power Connection: Plug the power cord into a suitable electrical outlet (220 Volts).
