3.2. Installation Steps (Overview)

For a detailed visual guide on installation, please refer to the official installation video below. This video covers preparation, indoor unit installation, outdoor unit installation, and trial operation.

1. Mounting Plate Installation: Securely fix the indoor unit mounting plate to a hard, flat, and firm wall using expansion screw kits. Ensure it is horizontal using a level.
2. Drill Wall Hole: Drill a hole through the wall for the refrigerant pipes and electrical cables. Ensure the hole is inclined slightly downward (5-10 degrees) to allow for proper drainage and avoid wires or plumbing.
3. Electrical Connection (Indoor Unit): Pass the power cable from the back of the indoor unit and fix it to the terminal board. Use a clamp to secure the cables.
4. Refrigerant Piping Connection (Indoor Unit): Connect the copper refrigerant pipes to the indoor unit. Tighten the taper nuts with fingers first, then use two wrenches, applying the specified torque (refer to the torque table in the video/manual).
5. Drain Hose Installation: Connect the drain hose to the water outlet pipe, ensuring it is firmly fixed and sloped downwards to prevent water accumulation.
6. Wrap Piping: Wrap the refrigerant piping, wires, and drain pipe together with wrapping tape for protection and neatness.
7. Mount Indoor Unit: Carefully put the indoor unit onto the mounting plate, ensuring it clicks firmly into place.
8. Outdoor Unit Bracket Installation: Install the outdoor unit bracket on a firm and flat place on an exterior wall. Use at least 6 expansion bolts to ensure it is fixed firmly.
9. Mount Outdoor Unit: Place the outdoor unit onto the brackets and fix its feet with 4 screws.
10. Electrical Connection (Outdoor Unit): Remove the electrical box cover and fix cables to the terminal board according to the wiring diagram provided inside the box cover. Use clamps to fix cables.
11. Refrigerant Piping Connection (Outdoor Unit): Connect the refrigerant pipes to the outdoor unit's stop valves. Tighten the taper nuts with fingers, then use two wrenches with the specified torque.
12. Vacuumize: Before opening the refrigerant valves, vacuumize the system for at least 15 minutes to remove air and moisture. Ensure the pressure gauge value is ≤0.1MPa. After vacuumizing, maintain pressure for 3-5 minutes to check for leaks.
13. Open Valves: Open all liquid and gas valves on the outdoor unit to release the refrigerant into the system.
