- Level
- Screwdrivers (flat and Phillips)
- Pipe cutter
- Vacuum pump
- Manifold gauge set
Step-by-Step Installation
- Choose Installation Location: Select a location with proper clearance for airflow and service access, away from direct sunlight and heat sources.
- Mount Indoor Unit: Securely mount the indoor unit on a solid wall using the provided mounting plate, ensuring it's level.
- Install Outdoor Unit: Place outdoor unit on a stable, level surface with proper vibration isolation and adequate airflow clearance.
- Connect Refrigerant Pipes: Connect copper pipes between indoor and outdoor units, ensuring proper insulation and leak-free connections.
- Electrical Connection: Connect to a properly grounded 230V, 50Hz power supply according to UK wiring regulations.
- Connect Drain Hose: Install drain hose with proper downward slope to ensure condensate water drainage.
- Vacuum and Charge: Evacuate the system using a vacuum pump and charge with the specified amount of refrigerant.
- Test Run: Perform a complete system test to check cooling, heating, and all operational modes.
