Be assured you are buying a durable and reliable Air Conditioner. Its Triple Protect System prevents your unit's compressor from being overloaded by power surges and fluctuating electric currents via a built-in voltage stabilizer. It also has an anti-corrosive coating that stops the condenser and cabinet from rusting. Additionally, its larger condenser and optimized refrigerant flow mean it can endure extremely hot temperatures (up to 58ºC). Smart Installation is a self-diagnosis feature that ensures your unit is installed perfectly by your service engineer. It automatically checks for installation faults that can cause problems when using the air conditioner, including ineffective communication with the outdoor unit, poor refrigerant flow, among others.
