Installation Guide
Tools Needed:
- Vacuum pump with gauge manifold
- Refrigerant charging scale
- Torque wrench set
- Flaring tool kit
- Multimeter
- Level
- Drill with hole saw
Step-by-Step Installation
- Select Installation Location: Choose a location with proper clearance (minimum 30cm from ceiling, 15cm from walls) and solid wall structure.
- Mount Indoor Unit Bracket: Securely mount the mounting plate to the wall using appropriate anchors for wall type.
- Create Wall Opening: Drill a 65mm hole through the wall for refrigerant piping and drainage hose.
- Connect Refrigerant Pipes: Connect indoor and outdoor units with flare connections, ensuring proper torque specifications.
- Connect Drain Hose: Install drain hose with proper downward slope (minimum 1/100 gradient) to ensure proper drainage.
- Electrical Connection: Connect to dedicated circuit with proper grounding according to local electrical codes.
- Vacuum and Charge: Evacuate system to 500 microns, hold for 15 minutes, then charge with specified refrigerant amount.
- Test Operation: Test all functions including cooling, heating, fan speeds, and remote control operation.
