Installation Guide
Tools Needed:
- Refrigeration manifold gauge set
- Vacuum pump
- Tubing cutter and bender
- Torque wrench set
- Multimeter
- Leak detector
- Level
Step-by-Step Installation
- Site Selection: Choose a location for outdoor unit with proper clearance (minimum 24" on all sides) on a solid, level concrete pad.
- Indoor Unit Placement: Install indoor evaporator unit in central location with proper drainage slope and air circulation.
- Refrigerant Line Installation: Run insulated copper lines between indoor and outdoor units with proper bends (minimum radius 4x tube diameter).
- Electrical Connections: Connect to dedicated 230V, 60Hz circuit with proper disconnect switch and circuit breaker protection.
- Drain Line Installation: Install condensate drain line with proper slope (1/4" per foot) and trap near indoor unit.
- Vacuum and Charge: Evacuate system to 500 microns minimum, then charge with specified refrigerant amount.
- System Startup: Perform complete system startup procedure including airflow measurement and refrigerant superheat/subcooling check.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not cooling | Power issue, thermostat setting, refrigerant leak | Check circuit breaker, verify thermostat settings, check for leaks |
| Poor cooling performance | Dirty filters, low refrigerant, restricted airflow | Clean/replace filters, check refrigerant charge, clear obstructions |
| Unit cycles on/off frequently | Dirty coils, incorrect charge, oversized unit | Clean coils, verify proper charge, check sizing calculations |
| Water leakage | Clogged drain line, improper slope, frozen coil | Clear drain line, ensure proper slope, check airflow |
| Unusual noises | Loose parts, debris in fan, bearing wear | Tighten all fasteners, clear debris, check motor bearings |
| High energy consumption | Dirty filters, low refrigerant, duct leaks | Clean filters, check charge, seal ductwork |
