3.2. Mounting Plate Installation

• Use the provided installation template to mark the precise location for the mounting plate and the wall hole for the line set.
• Drill holes at the marked positions.
• Secure the mounting plate to the wall using expansion screws. Do not use nails.

3.3. Wall Hole Drilling

• Drill a wall hole (60-80mm diameter) inclined outward by 5-10 degrees to allow for proper drainage.
• Use an anti-dust bag to collect dust during drilling.
• Ensure to avoid wires, plumbing, gas lines, and other sensitive components.

3.4. Wiring Connections

• Pass the power cable out from the back of the indoor unit and fix it on the terminal board.
• Fix the cable with a clamp to prevent accidental disconnection.
• For the outdoor unit, remove the electrical box cover and connect cables to the terminal board according to the wiring diagram provided on the E-parts cover. Use clamps to fix cables.

3.5. Refrigerant Piping Connection

• Carefully bend the refrigerant pipes to align with the wall hole. Use both hands to turn the pipe to avoid deformation or rupture.
• Aim at the pipe center, tighten the taper nut with fingers, then use two wrenches to fully tighten. Refer to the torque specifications provided in the manual for correct tightening.
• Connect the refrigerant pipes to the outdoor unit, ensuring snug fit and proper tightening with two wrenches.

3.6. Drain Hose Installation

• Connect the drain hose with the water outlet pipe, ensuring a firm fit with adhesive tape. The length should be more than 5cm.
• The drain hose should be sloped downwards to prevent water accumulation. Never put the end of the drain hose in water.

3.7. Wrapping and Mounting

• Wrap refrigerant piping, wires, and drain pipe together with wrapping tape for a neat and protected bundle.
• Put the refrigerant piping out of the wall hole.
• Mount the indoor unit on the mounting plate. Push the lower part of the indoor unit until a 'click' sound is heard to ensure it's firmly fixed.
• Install a pipe protecting ring and seal with putty around the wall hole to protect piping and wires.

3.8. Vacuumizing

• Before vacuumizing, check all nuts of the indoor and outdoor unit are tightened.
• Connect the stop valve, charging hose, manifold valve, and vacuum pump as shown in the diagram.
• Turn on the handle Lo to vacuumize for at least 15 minutes, ensuring the pressure gauge value is ≤-0.1MPa.
• Keep pressure for 3-5 minutes after vacuumizing; make sure pressure springback is ≤0.05MPa.
• Open 1/4 liquid valve, then remove the charging hose.
• Open all the liquid valves and gas valves. Screw all the caps and tighten up.
