Installation Guide
Tools Needed:
- Vacuum pump
- Manifold gauge set
- Torque wrench
- Flaring tool
- Tube cutter
- Leak detector
- Multimeter
- Level
Step-by-Step Installation
- Select Installation Location: Choose a location with proper structural support, away from heat sources, and with adequate clearance for airflow and maintenance.
- Mount Indoor Unit: Install mounting plate securely to wall, ensuring it is level. Hang indoor unit on plate and secure properly.
- Install Outdoor Unit: Place outdoor unit on stable pad or mounting brackets with proper vibration isolation. Ensure minimum clearance requirements are met.
- Connect Refrigerant Lines: Run insulated copper lines between indoor and outdoor units. Use proper flaring techniques and torque specifications for connections.
- Electrical Connections: Connect power wiring according to local electrical codes. Ensure proper grounding and circuit protection.
- Connect Drain Line: Install condensate drain line with proper slope (minimum 1/4" per foot) and route to appropriate drainage point.
- Vacuum and Charge System: Evacuate system to 500 microns or less. Charge with correct refrigerant type and amount specified by manufacturer.
- Test Operation: Start system and verify proper operation. Check temperature differential, airflow, and system pressures.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not cooling | Low refrigerant, dirty filters, thermostat issue | Check refrigerant charge, clean filters, verify thermostat settings |
| Unit not turning on | Power loss, tripped breaker, safety lockout | Check power supply, reset breaker, wait for safety reset |
| Water leakage | Clogged drain line, improper slope, frozen coil | Clear drain line, adjust slope, check for ice formation |
| Unusual noises | Loose parts, debris in fan, vibration | Tighten mounting hardware, clear debris, check isolation |
| Poor airflow | Dirty filters, blocked vents, fan issue | Clean/replace filters, clear obstructions, check fan operation |
| Short cycling | Dirty coils, oversized unit, thermostat location | Clean coils, verify sizing, relocate thermostat if needed |
