Outline and Dimensions

The indoor unit has dimensions of 257 mm (height) x 808 mm (width) x 187 mm (depth). The outdoor unit has dimensions of 700 mm (height) x 900 mm (width) x 350 mm (depth). Diagrams show front, side, and top views with specific measurements indicated.

Refrigerant System Diagram

The refrigerant system diagram illustrates the flow of refrigerant through the system. Key components include the compressor, heat exchanger (condenser), expansion valves (A and B), and indoor unit evaporators (A and B). A 4-way heat/cool valve is shown, enabling switching between heating and cooling modes. Thermistors are placed at various points, including the pipe, condenser, and discharge pipe, to monitor temperatures.

Circuit Diagram

The document includes detailed circuit diagrams for both the indoor and outdoor units. These diagrams illustrate the electrical connections between various components, including printed circuit boards (PCBs), power supply units, fan motors, compressors, relays, transformers, and sensors (thermistors). The diagrams show wiring configurations, component designations, and power flow.

Indoor PCB Circuit Diagram

This diagram details the internal circuitry of the indoor unit's main control PCB. It shows connections to sensors (room temperature, pipe temperature), motors, displays, switches, and external interfaces. Jumper wire configurations for functions like heating/cooling compensation are also illustrated.

Outdoor PCB Circuit Diagram

This diagram outlines the electrical connections for the outdoor unit's control PCB. It depicts connections to the compressor, fan motor, various sensors (discharge pipe temperature, outdoor temperature, condenser temperature), expansion valves, and the communication interface with the indoor unit. It also shows power supply components and protection circuits.

Disassembly Illustration

Exploded view diagrams are provided for both the indoor and outdoor units, illustrating how the units are assembled and can be disassembled for servicing. These diagrams show the arrangement of panels, filters, internal components like motors, fans, PCBs, compressors, and various brackets and fasteners. Each part is typically labeled with a reference number for identification in the parts list.

Indoor Unit Disassembly

Illustrations show the breakdown of the indoor unit, starting with the front panel, air cleaning filters (electric filter, ion deodorant filter), and proceeding to internal components such as the fan, motor, PCB, and heat exchanger assembly.

Outdoor Unit Disassembly

Illustrations detail the disassembly of the outdoor unit, showing the outer casing, fan, compressor, various PCBs, capacitors, and connection terminals. The diagrams highlight the placement and assembly of these components.
