Installation Guide
Tools Needed:
- Phillips screwdriver
- Level
- Drill with appropriate bits
- Tape measure
- Wire strippers
- Vacuum pump and gauges
Step-by-Step Installation
- Select Installation Location: Choose a location with proper clearance (minimum 30cm from ceiling, 15cm from walls) and away from heat sources.
- Mount Wall Bracket: Secure the mounting bracket to the wall using appropriate anchors for your wall type.
- Connect Refrigerant Pipes: Connect copper pipes between indoor and outdoor units, ensuring proper insulation and leak-free connections.
- Electrical Connection: Connect power cables to the designated terminals following local electrical codes. Ensure proper grounding.
- Drainage Installation: Install drain hose with proper downward slope (minimum 1/100 gradient) to ensure water drainage.
- Vacuum and Charge: Evacuate air and moisture from refrigerant lines using vacuum pump, then charge with specified refrigerant amount.
- Test Operation: Power on the system and test all functions including cooling, heating, fan speeds, and remote control operation.
