Installation Guide
Tools Needed:
- Refrigerant manifold gauge set
- Vacuum pump
- Tubing cutter and bender
- Flaring tool set
- Torque wrench
- Multimeter
- Leak detector
- Level
Step-by-Step Installation
- Site Preparation: Select appropriate location with proper clearances, solid mounting surface, and adequate ventilation.
- Mounting: Install mounting brackets securely to wall or concrete pad, ensuring level installation.
- Electrical Connection: Connect to dedicated circuit with proper voltage (208-230V) and install disconnect box within sight of unit.
- Refrigerant Lines: Install copper lines with proper insulation, ensure correct line sizes per manufacturer specifications.
- Drain Line Installation: Install condensate drain line with proper slope (1/4" per foot) and trap where required.
- Vacuum and Charge: Evacuate system to 500 microns, hold vacuum for 30 minutes, then charge with correct refrigerant type and amount.
- Startup and Testing: Test all functions, measure temperature differential, verify proper airflow, and check for leaks.
- Commissioning: Complete system startup sheet, register warranty, and provide customer orientation.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not cooling | Power loss, thermostat issue, refrigerant leak | Check circuit breaker, verify thermostat settings, check for leaks |
| Poor cooling performance | Dirty filters, low refrigerant, restricted airflow | Clean/replace filters, check charge, clear obstructions |
| Unit cycles on/off frequently | Dirty condenser, incorrect charge, oversized unit | Clean condenser coil, verify refrigerant charge, check sizing |
| Water leakage | Clogged drain line, improper slope, broken drain pan | Clear drain line, ensure proper slope, replace drain pan |
| Unusual noises | Loose parts, debris in fan, failing motor bearings | Tighten all fasteners, clear debris, replace motor if needed |
| Ice formation on coils | Low airflow, low refrigerant, dirty evaporator | Check filters and blower, verify charge, clean evaporator |
| High energy consumption | Dirty coils, incorrect charge, air leaks in ductwork | Clean coils, verify charge, seal duct leaks |
