Installation Guide
Tools Needed:
- Vacuum pump
- Manifold gauge set
- Torque wrench
- Flaring tool
- Level
- Drill with core bit
Step-by-Step Installation
- Select Installation Location: Choose a location with proper clearance (minimum 15cm from ceiling, 10cm from walls) and away from heat sources.
- Mount Indoor Unit Bracket: Securely mount the wall bracket using appropriate anchors for your wall type.
- Drill Wall Hole: Drill a 65mm hole through the wall with a slight downward slope to the outside for drainage.
- Connect Refrigerant Pipes: Connect copper pipes between indoor and outdoor units, ensuring proper insulation and flare connections.
- Connect Drain Hose: Route drain hose with continuous downward slope to proper drainage location.
- Electrical Connection: Connect to dedicated circuit with proper grounding according to local electrical codes.
- Vacuum and Charge: Evacuate system with vacuum pump for minimum 15 minutes, then release refrigerant charge.
- Test Operation: Test all functions including cooling, heating, fan speeds, and remote control operation.
