Installation Guide
Tools Needed:
- Vacuum pump with gauge manifold
- Refrigerant charging scale
- Torque wrench
- Flaring tool set
- Tube cutter and bender
- Multimeter
- Level
Step-by-Step Installation
- Select Installation Location: Choose a location with proper clearance (minimum 30cm from ceiling, 15cm from walls) and away from heat sources.
- Mount Indoor Unit Bracket: Securely mount the mounting plate to the wall using appropriate anchors for wall type.
- Drill Pipe Hole: Drill a 65mm hole through the wall with a slight downward slope to the outside for drainage.
- Connect Refrigerant Pipes: Connect indoor and outdoor units with flare connections, ensuring proper insulation on pipes.
- Connect Drain Hose: Install drain hose with proper downward slope (minimum 1/100 gradient) and insulation.
- Electrical Connection: Connect to dedicated circuit with proper grounding according to local electrical codes.
- Vacuum and Charge: Evacuate system to 500 microns and charge with specified amount of R32 refrigerant.
- Test Operation: Test all functions including cooling, heating, fan speeds, and remote control operation.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not starting | Power outage, circuit breaker tripped, remote control batteries dead | Check power supply, reset circuit breaker, replace remote batteries |
| Poor cooling/heating | Dirty filters, blocked airflow, incorrect temperature setting | Clean filters, remove obstructions, set appropriate temperature |
| Water dripping indoors | Clogged drain pipe, improper installation slope | Clean drain pipe, ensure proper downward slope (1/100 minimum) |
| Unusual noises | Loose parts, debris in fan, ice formation | Tighten mounting screws, clean indoor/outdoor units, check for ice buildup |
| Foul odors | Dirty filters, mold growth in drain pan | Clean/replace filters, clean drain pan with mild disinfectant |
| Remote not working | Dead batteries, signal obstruction, distance too far | Replace batteries, ensure line of sight, stay within 7 meters |
