Installation Guide
Tools Needed:
- Vacuum pump with gauge manifold
- Refrigerant charging scale
- Torque wrench
- Flaring tool set
- Pipe cutter
- Multimeter
- Level
Step-by-Step Installation
- Select Installation Location: Choose a location with proper clearance (minimum 30cm from walls and ceilings) and solid wall structure.
- Mount Indoor Unit: Install mounting plate securely to wall, ensuring it is perfectly level using a spirit level.
- Connect Refrigerant Pipes: Connect copper pipes between indoor and outdoor units, ensuring proper insulation and airtight connections.
- Electrical Connections: Connect power cables according to local electrical codes. Ensure proper grounding and circuit protection.
- Connect Drain Hose: Install drain hose with proper downward slope (minimum 1/100 gradient) to ensure proper condensation drainage.
- Vacuum and Charge: Evacuate air and moisture from refrigerant lines using vacuum pump, then charge with specified amount of R32 refrigerant.
- Test Operation: Test all functions including cooling, heating, fan speeds, and remote control operation.
