Step-by-Step Installation
- Select Installation Location: Choose a location with proper clearance (minimum 12 inches on all sides), away from heat sources and direct sunlight.
- Prepare Mounting Surface: Ensure wall or window frame is structurally sound and can support the unit's weight.
- Install Mounting Brackets: Securely attach mounting brackets using appropriate anchors for your wall type.
- Connect Refrigerant Lines: Connect copper refrigerant lines between indoor and outdoor units, ensuring proper insulation.
- Electrical Connection: Connect to dedicated circuit with proper voltage (120V/240V depending on model). Follow local electrical codes.
- Drainage Setup: Install condensate drain line with proper slope (minimum 1/4 inch per foot) to ensure water drainage.
- Vacuum and Charge System: Evacuate air and moisture from refrigerant lines, then charge with specified refrigerant amount.
- Test Operation: Run system through complete cooling and heating cycles to check for proper operation and leaks.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit won't turn on | Power outage, tripped circuit breaker, remote control batteries dead | Check power supply, reset circuit breaker, replace remote batteries |
| Poor cooling/heating | Dirty filters, blocked airflow, refrigerant leak, outdoor unit obstructed | Clean filters, clear obstructions, check refrigerant levels |
| Water leaking indoors | Clogged drain line, improper installation slope, frozen evaporator | Clear drain line, ensure proper slope, check for ice buildup |
| Unusual noises | Loose parts, debris in fan, compressor issues | Tighten mounting hardware, clear debris from outdoor unit |
| Foul odors | Dirty filters, mold growth in drain pan | Clean filters, run self-cleaning cycle, clean drain pan |
| Remote not working | Dead batteries, signal obstruction, sensor issues | Replace batteries, ensure line of sight, check indoor unit sensor |
