This document is the Operation and Installation Manual for the Haier DUCT TYPE AIR CONDITIONER, specifically model AD160S2SM3FA. It provides comprehensive information for both users and professional installers to ensure safe and efficient operation and maintenance of the unit.
Function Description:
The Haier DUCT TYPE AIR CONDITIONER is designed for cooling and heating indoor spaces. It operates as a partial unit air conditioner, meaning it must be connected to a compatible outdoor unit. The system utilizes a heat pump for warming, concentrating heat from outdoor air to warm the indoor space. It features a "HOT KEEP" function to prevent cold drafts during heating startup and defrosting operations. The unit is designed for installation in various environments, including offices, restaurants, and residences, but specific precautions are outlined for industrial or challenging settings.
