This document serves as both an operation and installation manual for a Haier Duct Type Air Conditioner, covering models AD09SS1ERA(N)(P), AD12SS1ERA(N)(P), AD18SS1ERA(N)(P), and AD24SS1ERA(N)(P). It provides essential information for safe and effective use, installation, and maintenance of the appliance.
The Haier Duct Type Air Conditioner is designed to provide cooling and heating for various indoor environments, including offices, restaurants, and residences. It operates by circulating air through ducts, ensuring even distribution of conditioned air throughout a space. The system utilizes a heat pump mechanism for warming, concentrating heat from outdoor air to warm the indoor space. During heating, the "HOT KEEP" function prevents the discharge of cool air at startup and manages defrosting operations to maintain efficiency. The unit is designed to be installed in a ceiling-concealed manner, with air supply and return ducts connected to distribute and collect air.
The air conditioner offers both cooling and heating modes. In heating mode, the "HOT KEEP" function ensures a comfortable experience by preventing cold drafts at startup and automatically managing defrosting cycles. This function temporarily stops the indoor fan or heating operation for a few minutes when starting heating, during defrosting, or when the room thermostat actuates due to rising room temperature. The system automatically switches to ordinary heating mode once these conditions are met.
The unit's operation is influenced by ambient temperature, with specific ranges for cooling (indoor 18-32°C DB/14-23°C WB, outdoor -10-46°C DB/24°C WB) and heating (indoor 15-27°C DB/WB, outdoor -15-24°C DB/18°C WB). The system is not intended for use with external timers or separate remote-control systems.
The manual emphasizes the importance of proper grounding and adherence to electrical safety standards. It also highlights the need for adequate ventilation when operating the unit simultaneously with combustion apparatus to prevent oxygen deficiency. Users are cautioned against obstructing the ventilation grille, inserting objects into the inlet/outlet, or handling switches with wet hands. The system should not be used for purposes other than conditioning air, such as preserving food or precision devices.
Regular maintenance is crucial for the longevity and efficient operation of the Haier air conditioner. The manual outlines several key maintenance tasks:
The manual also provides troubleshooting guidance for common issues, such as the unit failing to start, insufficient cooling or heating, and unusual noises or smells. It distinguishes between actual malfunctions and normal operational sounds or phenomena, like water flowing sounds or cracking due to thermal expansion. For more complex issues or error codes, users are advised to contact their sales dealer. The importance of cutting off the power supply before adjusting internal settings like SW1-4 and SW1-5 for static pressure adjustment is highlighted to prevent invalid operation.
