Installation Guide
Tools Needed:
- Adjustable wrench set
- Vacuum pump and gauge manifold
- Refrigerant scale
- Flaring tool
- Tube cutter
- Torque wrench
- Multimeter
Step-by-Step Installation
- Select Installation Location: Choose a location with proper clearance (minimum 30cm from walls and ceilings) on a solid, level surface.
- Mount Indoor Unit: Securely mount the indoor unit bracket to the wall using appropriate anchors for your wall type.
- Install Outdoor Unit: Place outdoor unit on a level concrete pad or mounting brackets with proper vibration isolation.
- Connect Refrigerant Lines: Connect copper piping between indoor and outdoor units using flare connections. Ensure all connections are leak-free.
- Electrical Connection: Connect to dedicated circuit with proper voltage (220-240V, 50Hz). Follow local electrical codes.
- Vacuum and Charge: Evacuate system to 500 microns minimum, then charge with specified amount of R32 refrigerant.
- Test Operation: Test cooling and heating modes, check temperature differentials, and verify proper drainage.
