Installation Guide
Tools Needed:
- Multimeter
- Refrigerant manifold gauge set
- Vacuum pump
- Leak detector
- Pipe cutter and flaring tool
- Insulation tape and sealants
Step-by-Step Installation
- Site Preparation: Select a location with proper clearance for airflow and service access on a solid, level surface.
- Mounting: Install mounting brackets securely to wall or foundation according to manufacturer specifications.
- Refrigerant Lines: Connect copper refrigerant lines using proper flaring techniques and ensure all connections are leak-free.
- Electrical Connection: Connect to dedicated circuit with proper voltage (230V/208V) and install disconnect switch within sight of unit.
- Drain Line Installation: 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.
- System Testing: Test all modes (cooling/heating), check temperature differentials, and verify proper operation.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not turning on | Power issue, thermostat setting, circuit breaker | Check power supply, verify thermostat settings, reset circuit breaker |
| Insufficient cooling/heating | Dirty filters, low refrigerant, blocked airflow | Clean/replace filters, check refrigerant charge, clear obstructions |
| Unusual noises | Loose parts, debris in fan, compressor issues | Tighten mounting hardware, clear debris, check compressor |
| Water leakage | Clogged drain line, improper installation, frozen coil | Clear drain line, check installation slope, defrost system |
| Frequent cycling | Oversized unit, thermostat location, dirty coils | Check unit sizing, relocate thermostat, clean coils |
| Ice formation on coils | Low airflow, low refrigerant, dirty filters | Check airflow, verify refrigerant charge, clean filters |
