Installation Guide
Tools Needed:
- Adjustable wrench
- Level
- Screwdrivers (flat and Phillips)
- Pipe cutter
- Vacuum pump
- Manifold gauge set
- Torque wrench
Step-by-Step Installation
- Choose Installation Location: Select a location with proper clearance (minimum 30cm from walls and ceilings) and adequate structural support.
- Mount Indoor Unit: Install mounting plate securely on wall, ensuring it is perfectly level. Hang indoor unit on plate.
- Install Outdoor Unit: Place outdoor unit on stable, level surface with proper ventilation (minimum 50cm clearance on all sides).
- Connect Refrigerant Pipes: Connect copper pipes between indoor and outdoor units using flare connections. Ensure proper insulation.
- Electrical Connection: Connect to dedicated circuit with proper voltage (220-240V, 50Hz). Follow local electrical codes.
- Vacuum and Charge: Evacuate air and moisture from refrigerant lines using vacuum pump, then charge with specified refrigerant amount.
- Test Run: Run the air conditioner in cooling and heating modes to check for proper operation and refrigerant leaks.
