Installation Guide
Tools Needed:
- Refrigeration gauge manifold
- Vacuum pump
- Torque wrench
- Flaring tool
- Pipe cutter
- Multimeter
- Level
Step-by-Step Installation
- Select Installation Location: Choose a location for outdoor unit with proper clearance (minimum 30cm from walls) on a solid, level concrete pad.
- Mount Indoor Units: Install indoor units on interior walls with proper spacing from ceiling (minimum 15cm) and walls (minimum 10cm).
- Install Refrigerant Piping: Connect copper piping between outdoor and indoor units using proper insulation and flare connections.
- Electrical Connections: Connect power supply to outdoor unit (240V, 60Hz) and indoor units according to local electrical codes.
- Communication Wiring: Install communication wiring between outdoor unit and all indoor units using shielded cable.
- Drainage System: Install condensate drain lines with proper slope (minimum 1/100 gradient) and trap for each indoor unit.
- Vacuum and Charge: Evacuate system to 500 microns, hold vacuum for 30 minutes, then charge with specified refrigerant amount.
- System Test: Power on system, test all functions, modes, and verify proper operation of all zones.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| System won't start | Power outage, circuit breaker tripped, remote control batteries dead | Check power supply, reset breaker, replace remote batteries |
| Poor cooling/heating | Dirty filters, blocked airflow, refrigerant leak | Clean filters, clear obstructions, contact technician for leak check |
| Water leakage | Clogged drain line, improper slope, frozen coil | Clear drain line, ensure proper slope, check for ice on coil |
| Unusual noises | Loose parts, debris in fan, vibration | Tighten mounting hardware, clear debris, check isolation |
| Error code displayed | System fault, sensor failure, communication error | Note error code, power cycle system, contact technician |
| Uneven temperatures | Improper zoning, airflow restrictions, sizing issue | Check zone dampers, clear vents, verify system capacity |
Common Error Codes
- E0: Outdoor unit protection - Check outdoor unit operation
- E1: Indoor unit PCB error - Power cycle indoor unit
