Installation Guide
Tools Needed:
- Refrigerant manifold gauge set
- Vacuum pump
- Tube bender and cutter
- Torque wrench set
- Multimeter
- Leak detector
- Insulation tape and sealants
Step-by-Step Installation
- Site Selection: Choose a location with proper clearance (minimum 30cm from walls), good airflow, and away from heat sources.
- Mounting Preparation: Install mounting brackets securely to wall studs or concrete using appropriate anchors.
- Refrigerant Line Installation: Connect copper lines between indoor and outdoor units, ensuring proper insulation and avoiding sharp bends.
- Electrical Connection: Connect to dedicated circuit with proper grounding. Follow local electrical codes and manufacturer specifications.
- Drainage System: Install condensate drain line with proper slope (minimum 1% grade) and trap to prevent air lock.
- Vacuum and Charge: Evacuate system to 500 microns, hold for 15 minutes, then charge with specified refrigerant amount.
- System Testing: Test all functions including cooling, heating, fan speeds, and thermostat operation.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not turning on | Power loss, tripped breaker, faulty thermostat | Check power supply, reset breaker, verify thermostat settings |
| Insufficient cooling/heating | Dirty filters, low refrigerant, blocked airflow | Clean filters, check refrigerant charge, clear obstructions |
| Unit freezing up | Low airflow, dirty coils, low refrigerant | Check filters and coils, verify airflow, check refrigerant level |
| Water leakage | Clogged drain line, improper installation, frozen coil | Clear drain line, check installation slope, defrost system |
| Unusual noises | Loose parts, debris in fan, compressor issues | Tighten components, clean fan blades, check compressor mounts |
| Frequent cycling | Oversized unit, dirty filters, thermostat location | Verify unit sizing, clean filters, relocate thermostat if needed |
