Installation Guide
Tools Needed:
- Vacuum pump with gauge manifold
- Refrigerant scale
- Flaring tool set
- Tubing cutter
- Torque wrench
- Multimeter
- Drill with hole saw kit
- Level
- Pipe bender
Step-by-Step Installation
- Select Installation Location: Choose appropriate locations for indoor and outdoor units considering airflow, drainage, and structural support.
- Mount Indoor Unit Bracket: Securely mount the wall bracket using appropriate anchors for wall type, ensuring it is perfectly level.
- Drill Refrigerant Line Hole: Drill a 3-inch hole through the wall with a slight downward slope toward the outside for drainage.
- Install Refrigerant Lines: Connect copper tubing between indoor and outdoor units, ensuring proper insulation and avoiding sharp bends.
- Connect Drainage Line: Install condensate drain line with proper slope (minimum 1/4 inch per foot) and route to appropriate drainage point.
- Electrical Connections: Connect power and communication cables following local electrical codes and manufacturer specifications.
- Vacuum and Charge System: Evacuate the system to 500 microns, hold for 15 minutes, then charge with specified refrigerant amount.
- Test Operation: Test all functions including cooling, heating, fan speeds, and thermostat operation.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not turning on | Power outage, tripped breaker, remote control issue | Check power supply, reset circuit breaker, replace remote batteries |
| Poor cooling/heating performance | Dirty filters, low refrigerant, blocked airflow | Clean filters, check refrigerant charge, clear obstructions |
| Water leakage from indoor unit | Clogged drain line, improper installation slope | Clear drain line, ensure proper drainage slope |
| Unusual noises | Loose parts, debris in fan, vibration | Tighten mounting hardware, clear debris, check isolation |
| Ice formation on coils | Low refrigerant, dirty filters, low airflow | Check refrigerant charge, clean filters, check fan operation |
| Remote control not working | Dead batteries, signal obstruction, sensor issue | Replace batteries, ensure line of sight, check sensor |
Error Codes
