3. Setup and Installation

Proper installation is crucial for the efficient and safe operation of your mini-split system. It is strongly recommended to hire a certified professional for installation. Self-installation may void the warranty.

3.1 Site Selection

• Indoor Unit: The wall for the indoor unit should be hard, flat, and firm to prevent vibration and noise. Ensure adequate clearance: >15cm to ceiling, >20cm to obstacles on sides, and 230-260cm from floor.
• Outdoor Unit: Must be installed in a firm and flat place to prevent vibration and noise. Ensure adequate clearance: >20cm above, >10cm on air-in side, >30cm on air-out side and other sides. Avoid locations near heat/steam sources, obstructions around inlet/outlet, or flammable/corrosive gases.

3.2 Installation Steps (Overview)

1. Mounting Plate: Fix the mounting plate on the wall using expansion screw kits. Use a level to ensure it is horizontal.
2. Drill Wall Hole: After determining where the pipes will go, drill a wall hole inclined outward by 5-10 degrees, with a diameter of 60-80mm. Use an anti-dust bag.
3. Connect Cables: Pass the power cable out from the back of the indoor unit and fix it on the terminal board according to the wiring diagram.
4. Connect Refrigerant Piping: Aim at the pipe center, tighten the taper nut with fingers, then tighten with two wrenches. Use a torque wrench for precise tightening (refer to manual for torque specs based on pipe size).
5. Install Drain Hose: Connect the drain hose with the water outlet pipe, ensuring the length is more than 5cm to prevent water leakage. Fix it firmly with adhesive tape.
6. Wrap Piping: Wrap refrigerant piping, wires, and drain pipe with wrapping tape.
7. Mount Indoor Unit: Put the refrigerant piping out of the wall hole, then mount the indoor unit on the mounting plate. Push the lower part until a 'click' sound is heard.
8. Pipe Protecting Ring and Putty: Install a pipe protecting ring and seal with putty to protect piping and wires.
9. Install Outdoor Unit Bracket: If mounting on a wall, use a level to ensure the bracket is horizontal and vertical. Use at least 6 expansion bolts.
10. Fix Outdoor Unit: Place the outdoor unit on the bracket or a stable base. Use 4 screws to fix the feet.
11. Connect Outdoor Refrigerant Piping: Remove the nut from stop valves, aim at the pipe center, tighten the taper nut with fingers, then tighten with two wrenches.
12. Fix Outdoor Cables: Remove the electrical box cover and fix cables to the terminal board according to the wiring diagram on the E-parts cover.
13. Vacuumize: Before vacuuming, check all nuts are tightened. Connect stop valve, charging hose, manifold valve, and vacuum pump. Vacuum for at least 15 minutes until the pressure gauge value is ≤0.1MPa. Keep pressure for 3-5 minutes after vacuumizing to ensure no springback.
14. Release Refrigerant: Open 1/4 liquid valve, then remove charging hose. Open all liquid and gas valves. Screw all caps and tighten up.
