This document is an installer manual for the NIBE AG-AA10 series of air/air heat pumps, covering models AG-AA10-30, AG-AA10-40, and AG-AA10-50. It provides essential information for the safe and efficient installation, maintenance, and troubleshooting of these units.

Function Description

The NIBE AG-AA10 is an air/air heat pump designed to provide both cooling and heating functions for indoor environments. It operates by transferring heat between the indoor and outdoor air using a refrigerant circuit. The system consists of an outdoor unit (AG-AA10 series) and a corresponding indoor unit (AG-WT10 series, e.g., AG-WT10-4 or AG-WT10-7). The manual details the procedures for connecting the cooling circuit and electrical components, ensuring proper functionality and safety. It also covers "Pump down" procedures, which involve retrieving all refrigerant into the outdoor unit without losing the system's filling, necessary for moving the climate unit or during cooling circuit repair.

Important Technical Specifications

Usage Features

The manual primarily focuses on installation and maintenance rather than end-user features. However, it highlights the importance of correct installation for safe and efficient operation. The heat pump is designed for use in various climate conditions, with specified working ranges for both cooling and heating. It is capable of connecting to several different indoor units.

Maintenance Features

The manual provides detailed instructions for maintenance and repair procedures, emphasizing safety precautions.

Safety during repair: Disconnect voltage before checking or repairing electrical parts, keep hands and clothing away from moving parts, clean thoroughly after work, and ensure proper ventilation during cooling circuit tests to prevent refrigerant gas leaks.
Troubleshooting: A dedicated section helps identify and resolve common disturbances in comfort. It includes a table of fault codes indicated by LED lights (DL3, DL4, DL5, DL6, DL7) on the outdoor unit's terminal blocks, corresponding to issues like defective sensors (compressor, outdoor temperature, evaporator), overcurrent on compressor or fan, overheated control electronics, fault in indoor unit, communication error, or phase monitor tripped.
"Pump down" procedure: This is a key maintenance feature allowing the retrieval of refrigerant into the outdoor unit for relocation or repair of the cooling circuit without losing the system's filling.
Condensation drain: The AG-CH10 accessory is required for proper condensation removal to an external drain.
Pipe connections: Instructions for using the flare method, lubricating contact surfaces, and tightening connections with a torque wrench are provided to ensure a secure, leak-free cooling circuit. Leak tracing with nitrogen and soapy water is recommended before the function test.
Vacuuming: The manual details the process of vacuuming the indoor unit and refrigerant pipe using a vacuum pump connected to the outdoor unit, crucial for removing air and dampness that could negatively affect the heat pump's function.
