This document outlines the disassembly procedures for an indoor unit, focusing on various components for maintenance and repair. The instructions are presented with corresponding illustrations to guide the user through each step.
The first step in disassembling the indoor unit involves removing the front panel. This process begins by holding the front panel by the tabs located on both sides and lifting it upwards. This action, illustrated as CJ_AB_INV_001, detaches the panel from its main housing. Following this, the air filter needs to be removed. This is done by pushing up the bottom of the air filter (step 1) and then pulling it out downwards (step 2), as shown in CJ_AB_INV_002. This allows access to the internal components.
Next, the horizontal louver must be opened. This involves pushing a hook towards the left to release it, as depicted in CJ_AB_INV_003. Once the hook is released, the horizontal louver can be bent lightly with both hands to loosen its hooks, allowing it to be removed from the unit, as illustrated in CJ_AB_INV_004.
The electrical cover is then addressed. Using a screwdriver, the electrical cover is pried and rotated towards the left before being removed, as shown in CJ_AB_INV_005. After the cover is off, the connector for the display board needs to be disconnected, a step detailed in CJ_AB_INV_006.
Further disassembly of the front panel involves sliding it side to side to release each axis, as illustrated in CJ_AB_INV_007. Once the axes are released, a screw cap is opened, and three screws are removed, as shown in CJ_AB_INV_008.
The next steps involve releasing various hooks. First, the hooks on the front panel are released with hands, as depicted in CJ_AB_INV_009. Following this, five hooks located at the back of the unit are released, as shown in CJ_AB_INV_010. Finally, the panel frame is pulled out while pushing a hook through a clearance between the panel frame and the heat exchanger, as illustrated in CJ_AB_INV_011.
The vertical blades are then removed. This involves releasing five hooks of the vertical blades and then pulling them rightward to remove them, as shown in CJ_AB_INV_012.
The display board is the next component to be removed. One screw of the display board is removed, as illustrated in CJ_AB_INV_013. After removing the screw, the display board is rotated in the direction shown in the illustration to fully detach it.
Disassembly of electrical parts requires antistatic gloves to prevent damage. It is crucial to remove the front panel first, as described in the previous section, before proceeding with electrical components.
The process begins by cutting a ribbon with shears and then pulling out the coil temperature sensor (T2), as shown in CJ_AB_INV_014. Concurrently, one fixing screw of the electronic control box and two screws used for the ground connection are removed, also depicted in CJ_AB_INV_014.
An upward force is maintained until the cover of the electronic control box is removed, as illustrated in CJ_AB_INV_015.
Next, the fixed devices of the connectors are removed, as shown in CJ_AB_INV_016. Following this, the connectors for the fan motor, step motor, and T2 sensor are disconnected, as detailed in CJ_AB_INV_017.
The left side plate of the electronic control box is then opened, as illustrated in CJ_AB_INV_018.
Further steps involve opening two clips on the front of the electric box, as shown in CJ_AB_INV_019. After this, the upper cover plate of the electronic control box is opened, as depicted in CJ_AB_INV_020.
The electrical main board is then removed. This involves removing one screw and opening two clips along the indicated direction, as shown in CJ_AB_INV_021. Finally, the electrical main board is pulled out along the indicated direction to remove it, as illustrated in CJ_AB_INV_022.
Before disassembling the evaporator, the front panel and all electrical parts must be removed, as detailed in the previous sections.
The first step is to disassemble the pipe holder located at the rear of the unit, as shown in CJ_AB_INV_023. Following this, one screw on the evaporator, located at the fixed plate, is removed, as illustrated in CJ_AB_INV_024.
Next, a hook on the evaporator is released, as depicted in CJ_AB_INV_025. Then, one screw on the evaporator, located at the fixed plate, is removed, as shown in CJ_AB_INV_026. Finally, the evaporator is pulled out, as illustrated in CJ_AB_INV_027.
To disassemble the fan motor and fan, the front panel, electrical parts, and evaporator must first be removed.
The process begins by removing two screws and the fixing board of the fan motor, as shown in CJ_AB_INV_028. Following this, the bearing sleeve is removed, as illustrated in CJ_AB_INV_029.
Next, the fixing screw is removed, as depicted in CJ_AB_INV_030. Finally, the fan motor and fan assembly are pulled out from the side.
Before disassembling the step motor, the front panel and electrical parts must be removed.
The procedure involves removing two screws and then removing the stepping motor, as shown in CJ_AB_INV_031.
The final component covered is the drain hose.
The process involves rotating the fixed wire clockwise, as indicated in CJ_AB_INV_032. After this, the drain hose is pulled up to remove it, as illustrated in CJ_AB_INV_033.
This comprehensive guide ensures that each component can be safely and effectively disassembled for maintenance or replacement. The illustrations provided are crucial for visual guidance during these procedures.
