Step 4: Outlet Pipe

1. The pipe can be led out in the direction of right, rear right, left, or rear left.
2. When leading the pipe from the left or right, cut off the corresponding hole on the bottom case.

Diagram description: Shows the possible directions for the outlet pipe and how to cut the bottom case.

Step 5: Connect the Pipe of Indoor Unit

1. Align the pipe joint with the corresponding bellmouth.
2. Pre-tighten the union nut by hand.
3. Adjust torque force as per the following sheet. Place an open-end wrench on the pipe joint and a torque wrench on the union nut. Tighten the union nut with the torque wrench.

4. Wrap the indoor pipe and connection pipe joint with insulating pipe, then wrap with tape.

Diagram description: Shows wrapping the pipe with insulating pipe and tape.

Step 6: Install Drain Hose

1. Connect the drain hose to the outlet pipe of the indoor unit.
2. Bind the joint with tape.

Diagram description: Shows connecting the drain hose to the outlet pipe and binding it.

NOTE: Add insulating pipe in the indoor drain hose to prevent condensation. Plastic expansion particles are not provided.

Step 7: Connect Wire of Indoor Unit

NOTICE: All wires of indoor and outdoor units must be connected by a professional. If the power connection wire length is insufficient, contact the supplier. Avoid extending wires yourself. For units with a plug, the plug must be reachable after installation. For units without a plug, an air switch must be installed in the line, with all-pole parting and contact separation of more than 3mm.

1. Open the panel, remove the screw on the wiring cover, and take down the cover.
2. Make the power connection wire go through the cable-cross hole at the back of the indoor unit and pull it out from the front side.

Diagram description: Shows opening the panel, removing the cover, and routing the power wire.

3. Remove the wire clip; connect the power connection wire to the wiring terminal according to the color; tighten the screw and fix the wire with the clip.

Wiring diagrams are provided for 09K and 12K/18K/24K models, showing connections for yellow-green, blue, black, and brown wires to N(1), 2, 3 terminals.

NOTICE: The wiring board is for reference only; refer to the actual one.

4. Put the wiring cover back and tighten the screw.
5. Close the panel.

Step 8: Bind Up Pipe

1. Bind the connection pipe, power cord, and drain hose together with a band.
2. Reserve a certain length of drain hose and power cord for installation when binding. When binding to a certain degree, separate the indoor power cord and then the drain hose.
3. Bind them evenly.
4. The liquid pipe and gas pipe should be bound separately at the end.

Diagram description: Shows binding pipes, power cord, and drain hose.

NOTICE:

• The power cord and control wire must not be crossed or wound.
• The drain hose should be bound at the bottom.

Step 9: Hang the Indoor Unit

1. Put the bound pipes into the wall pipe and pass them through the wall hole.
2. Hang the indoor unit on the wall-mounting frame.
3. Stuff the gap between the pipes and the wall hole with sealing gum.
4. Fix the wall pipe.
5. Check if the indoor unit is installed firmly and is close to the wall.

Diagram description: Shows pipes passing through the wall, the indoor unit hanging on the frame, and sealing the gap.

NOTICE: Do not bend the drain hose excessively to prevent blocking.

Step 1: Fix the Support of Outdoor Unit

(Select according to the actual installation situation)

1. Select installation location according to the house structure.
2. Fix the support of the outdoor unit on the selected location with expansion screws.

Diagram description: Shows the outdoor unit placed on a support, with labels for drain vent, chassis, outdoor drain joint, and drain hose. Indicates a minimum height of 3cm above the floor.

NOTICE:

• Take sufficient protective measures when installing the outdoor unit.
• Ensure the support can withstand at least four times the unit's weight.
• The outdoor unit should be installed at least 3cm above the floor to install the drain joint. (For models with heating tubes, the height should be no less than 20cm.)
• For units with cooling capacity of 2300W~5000W, 6 expansion screws are needed; for 6000W~8000W, 8 screws; for 10000W~16000W, 10 screws.

Step 2: Install Drain Joint

(Only for some models)

1. Connect the outdoor drain joint into the hole on the chassis, as shown in the picture.
2. Connect the drain hose into the drain vent.

Diagram description: Shows connecting the drain joint and drain hose.

NOTICE: As for the shape of the drainage joint, please refer to the current product. Do not install the drainage joint in severe cold areas, as it may freeze and cause malfunction.

Step 3: Fix Outdoor Unit

1. Place the outdoor unit on the support.
2. Fix the foot holes of the outdoor unit with bolts.

Diagram description: Shows placing the unit on the support and fixing it with bolts.

Step 4: Connect Indoor and Outdoor Pipes

1. Remove the screw on the right handle of the outdoor unit and then remove the handle.
2. Remove the screw cap of the valve and align the pipe joint with the bellmouth of the pipe.
3. Pre-tighten the union nut by hand.

Diagram description: Shows removing the handle, removing the valve cap, and aligning the pipe joint. Labels liquid valve, liquid pipe, gas valve, gas pipe.

4. Tighten the union nut with a torque wrench by referring to the sheet below.

Step 5: Connect Outdoor Electric Wire

1. Remove the wire clip; connect the power connection wire and signal control wire (only for cooling and heating units) to the wiring terminal according to the color; fix them with screws.

Wiring diagram for indoor unit connection is shown.

NOTICE: The wiring board is for reference only; refer to the actual one.

2. Fix the power connection wire and signal control wire with a wire clip (only for cooling and heating units).

NOTICE:

• After tightening the screw, pull the power cord slightly to check if it is firm.
• Never cut the power connection wire to prolong or shorten the distance.

Step 6: Neaten the Pipes

1. The pipes should be placed along the wall, bent reasonably, and hidden if possible. The minimum bending radius is 10cm.
2. If the outdoor unit is higher than the wall hole, set a U-shaped curve in the pipe before it enters the room to prevent rain from entering.

Diagram description: Shows pipes placed along the wall and a U-shaped curve.

NOTICE:

• The through-wall height of the drain hose should not be higher than the outlet pipe hole of the indoor unit.
• The water outlet cannot be placed in water to ensure smooth drainage.
• Slant the drain hose slightly downwards. The drain hose should not be curved, raised, or fluctuant.

Diagram description: Illustrates correct and incorrect drain hose placements.

Use Vacuum Pump

1. Remove valve caps on the liquid and gas valves and the nut of the refrigerant charging vent.
2. Connect the charging hose of the piezometer to the refrigerant charging vent of the gas valve, and then connect the other charging hose to the vacuum pump.
3. Open the piezometer completely and operate for 10-15 minutes to check if the pressure remains at -0.1MPa.
4. Close the vacuum pump and maintain this status for 1-2 minutes to check if the pressure remains at -0.1MPa. If the pressure decreases, there may be a leakage.
5. Remove the piezometer, and fully open the valve cores of the liquid and gas valves using an inner hexagon spanner.
6. Tighten the screw caps of the valves and the refrigerant charging vent.
7. Reinstall the handle.

Diagram description: Shows the setup for using a vacuum pump, including liquid valve, gas valve, refrigerant charging vent, piezometer, valve cap, vacuum pump, and inner hexagon spanner.

Leakage Detection

1. With Leakage Detector: Check for leakage using a leakage detector.
2. With Soap Water: If a leakage detector is unavailable, use soap water. Apply soap water at suspected positions and wait more than 3 minutes. If air bubbles emerge, there is a leak.

Check After Installation

Check according to the following requirements after finishing installation.

Test Operation

1. Preparation of Test Operation
   • The client approves the air conditioner.
   • Specify important notes for the air conditioner to the client.
2. Method of Test Operation
   • Apply power, then press the ON/OFF button on the remote controller to start operation.
   • Press the MODE button to select AUTO, COOL, DRY, FAN, and HEAT to check if the operation is normal.
   • If the ambient temperature is lower than 16°C, the air conditioner cannot start cooling.
