Installation Guide
Tools Needed:
- Refrigeration manifold gauge set
- Vacuum pump
- Tubing cutter and bender
- Torque wrench
- Multimeter
- Level
- Drill with masonry bits
Step-by-Step Installation
- Site Selection: Choose location for outdoor unit with adequate clearance (minimum 30cm all sides), proper drainage, and away from heat sources.
- Mounting: Install mounting bracket for outdoor unit on solid wall or concrete pad. Ensure unit is level.
- Indoor Unit Placement: Mount indoor unit on interior wall, 2-2.5 meters above floor, away from direct sunlight and heat sources.
- Refrigerant Line Installation: Connect copper refrigerant lines between indoor and outdoor units. Ensure proper insulation on suction line.
- Electrical Connections: Connect power supply to outdoor unit (220-240V, dedicated circuit). Connect communication cable between indoor and outdoor units.
- Drainage System: Install condensate drain line with proper slope (minimum 1% grade) to ensure water drainage.
- Vacuum and Charge: Evacuate system to 500 microns, hold for 15 minutes. Charge with specified refrigerant amount.
- System Test: Test cooling and heating modes, check for leaks, verify proper drainage and airflow.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not turning on | Power failure, tripped breaker, faulty remote | Check power supply, reset circuit breaker, replace remote batteries |
| Poor cooling performance | Dirty filters, low refrigerant, blocked condenser | Clean filters, check refrigerant charge, clear condenser area |
| Water leakage from indoor unit | Clogged drain line, improper installation | Clear drain line, ensure proper slope and insulation |
| Unusual noises | Loose parts, debris in fan, vibration | Tighten mounting hardware, clear debris, check isolation |
| Frozen evaporator coil | Low airflow, low refrigerant, dirty filter | Check fan operation, verify refrigerant charge, clean filter |
| Unit turns on/off frequently | Thermostat issues, dirty condenser, overcharge | Check thermostat location/calibration, clean condenser, verify charge |
