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 solid wall structure.
- Mount Indoor Unit: Install mounting plate securely on wall, ensuring it is perfectly level using a spirit level.
- Install Outdoor Unit: Place outdoor unit on stable, level surface with proper ventilation clearance (minimum 50cm all sides).
- Connect Refrigerant Pipes: Connect copper pipes between indoor and outdoor units using flare connections. Ensure pipes are properly insulated.
- Electrical Connection: Connect power cables according to local electrical codes. Ensure proper grounding and correct voltage (220-240V, 50Hz).
- Connect Drain Hose: Install drain hose with proper downward slope (minimum 1/100 gradient) to ensure proper drainage.
- 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.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not starting | Power issue, remote control batteries dead, circuit breaker tripped | Check power supply, replace remote batteries, reset circuit breaker |
| Poor cooling/heating | Dirty filters, blocked air vents, incorrect temperature setting | Clean filters, clear obstructions, set appropriate temperature |
| Water leaking indoors | Clogged drain pipe, improper installation slope | Clear drain pipe, ensure proper drainage slope |
| Unusual noises | Loose parts, debris in fan, ice formation | Tighten components, clean unit, check for ice buildup |
| Foul odors | Dirty filters, mold growth in drain pan | Clean filters and drain pan, use air purification mode |
| Remote not working | Dead batteries, signal obstruction, distance too far | Replace batteries, ensure line of sight, stay within 7 meters |
