Installation Guide
Tools Needed:
- Refrigerant gauges and manifold
- Vacuum pump
- Tubing cutter and bender
- Leak detector
- Electrical multimeter
- Drill with hole saw attachments
- Level and measuring tape
Step-by-Step Installation
- Site Selection: Choose appropriate locations for indoor and outdoor units considering airflow, drainage, and accessibility for maintenance.
- Mounting Brackets: Install mounting brackets for outdoor unit on a solid, level surface with proper vibration isolation.
- Refrigerant Line Installation: Run copper refrigerant lines between indoor and outdoor units with proper insulation to prevent condensation.
- Electrical Connections: Connect to dedicated circuit with proper grounding according to local electrical codes and manufacturer specifications.
- Drain Line Installation: Install condensate drain line with proper slope and trap to ensure proper drainage.
- Vacuum and Charge: Evacuate the system to remove moisture and air, then charge with specified refrigerant type and quantity.
- System Testing: Test all functions including cooling, heating (if applicable), fan speeds, and thermostat operation.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not turning on | Power outage, tripped breaker, faulty remote | Check power supply, reset circuit breaker, replace remote batteries |
| Insufficient cooling/heating | Dirty filters, low refrigerant, blocked airflow | Clean filters, check refrigerant charge, clear obstructions |
| Water leakage | Clogged drain line, improper installation slope | Clear drain line, ensure proper drainage slope |
| Unusual noises | Loose parts, debris in fan, worn bearings | Tighten components, clean fan blades, lubricate bearings |
| Frozen coils | Dirty filters, low refrigerant, restricted airflow | Clean filters, check refrigerant level, ensure proper airflow |
| Frequent cycling | Oversized unit, thermostat issues, dirty coils | Check sizing, calibrate thermostat, clean evaporator coils |
