Installation Guide
Tools Needed:
- Vacuum pump with gauge manifold
- Refrigerant charging scale
- Tubing cutter and flaring tool
- Torque wrench
- Multimeter
- Level
- Drill with hole saw
Step-by-Step Installation
- Select Installation Location: Choose a location with proper clearance (at least 15cm from ceiling, 30cm from walls) and away from heat sources.
- Mount Indoor Unit Bracket: Securely mount the bracket to the wall using appropriate anchors for your wall type.
- Install Refrigerant Piping: Connect refrigerant pipes between indoor and outdoor units, ensuring proper insulation on all piping.
- Electrical Connections: Connect power supply wiring according to local electrical codes and unit specifications.
- Drainage Installation: Install drain hose with proper downward slope (minimum 1/100 gradient) to ensure proper drainage.
- Vacuum and Charge: Evacuate the system using a vacuum pump, then charge with the specified amount of refrigerant.
- Test Operation: Test all functions including cooling, heating, fan speeds, and remote control operation.
