Installation Guide
Tools Needed:
- Vacuum pump with gauge manifold
- Refrigerant charging scale
- Tubing cutter and flaring tool
- Torque wrench
- Multimeter
- Level
- Drill with core bit
Step-by-Step Installation
- Select Installation Location: Choose a location with proper clearance (minimum 30cm from ceiling, 15cm from walls) and adequate structural support.
- Mount Indoor Unit Bracket: Securely mount the bracket to the wall using appropriate anchors for your wall type.
- Drill Wall Hole: Drill a 65mm diameter hole through the wall with a slight downward slope to the outside.
- Connect Refrigerant Pipes: Connect copper pipes between indoor and outdoor units, ensuring proper flaring and torque specifications.
- Connect Drain Hose: Install drain hose with proper downward slope (minimum 1/100 gradient) to ensure proper condensation drainage.
- Electrical Connection: Connect to dedicated circuit with proper grounding according to local electrical codes.
- Vacuum and Charge: Evacuate the system to 500 microns and charge with specified refrigerant amount.
- Test Operation: Test all functions including cooling, heating, fan speeds, and remote control operation.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not starting | Power failure, circuit breaker tripped, remote control batteries dead | Check power supply, reset circuit breaker, replace remote batteries |
| Poor cooling/heating | Dirty filters, blocked airflow, refrigerant leak, outdoor unit obstructed | Clean filters, clear obstructions, check for leaks, clear outdoor unit area |
| Water leakage | Clogged drain pipe, improper installation slope, frozen evaporator | Clean drain pipe, ensure proper slope, check for ice formation |
| Unusual noises | Loose parts, debris in fan, vibration from mounting | Tighten all screws, clear debris, check mounting stability |
| Frozen coils | Dirty filters, low refrigerant, fan motor failure | Clean filters, check refrigerant charge, inspect fan motor |
| Remote not working | Dead batteries, signal obstruction, sensor issue | Replace batteries, ensure line of sight, check indoor unit sensor |
