Installation Guide
Tools Needed:
- Adjustable wrench
- Level
- Screwdrivers (flat and Phillips)
- Pipe cutter
- Vacuum pump
- Manifold gauge
- Torque wrench
Step-by-Step Installation
- Choose Installation Location: Select a location with proper clearance (minimum 30cm from walls and ceilings) and strong wall support.
- Mount Indoor Unit Bracket: Securely mount the bracket to the wall using appropriate anchors for your wall type.
- Install Outdoor Unit: Place outdoor unit on a solid, level surface with proper ventilation clearance (minimum 50cm on all sides).
- Connect Refrigerant Pipes: Connect copper pipes between indoor and outdoor units, ensuring proper insulation and no kinks.
- Electrical Connection: Connect to a properly grounded 220-240V, 50Hz power supply with dedicated circuit breaker.
- Connect Drain Hose: Route drain hose with proper downward slope to ensure complete drainage.
- Vacuum and Charge: Evacuate air and moisture from refrigerant lines, then charge with specified refrigerant amount.
- Test Run: Run the air conditioner through all modes to check for proper operation and cooling/heating performance.
