- Screwdrivers (flat and Phillips)
- Tube cutter and flaring tool
- Vacuum pump
- Manifold gauge set
- Level
Step-by-Step Installation
- Choose Installation Location: Select a location with proper clearance for airflow, away from direct sunlight and heat sources.
- Mount Indoor Unit: Securely mount the indoor unit on a sturdy wall, ensuring proper leveling and clearance from ceiling and walls.
- Install Outdoor Unit: Place outdoor unit on a solid, level pad with proper vibration isolation and drainage considerations.
- Connect Refrigerant Lines: Connect copper refrigerant lines between indoor and outdoor units, ensuring proper insulation and leak-free connections.
- Electrical Connection: Connect to properly sized circuit with correct voltage (208-230V) and install disconnect switch within sight of unit.
- Connect Drain Line: Install condensate drain line with proper slope and trap to ensure proper drainage.
- Vacuum and Charge: Evacuate system to 500 microns, then charge with correct refrigerant type and amount per manufacturer specifications.
- Test Run: Test heating and cooling modes, check temperature differentials, and verify proper operation of all functions.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not turning on | Power issue, circuit breaker tripped, thermostat issue | Check power supply, reset circuit breaker, check thermostat settings |
| Poor cooling/heating performance | Dirty filters, low refrigerant, blocked airflow | Clean filters, check refrigerant charge, clear obstructions |
| Unit freezing up | Low airflow, dirty coils, low refrigerant | Clean filters and coils, check airflow, verify refrigerant charge |
| 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 mounting hardware, clear debris, check compressor |
| Short cycling | Dirty filters, thermostat location, oversized unit | Clean filters, relocate thermostat, check system sizing |
