Installation Guide
Tools Needed:
- Refrigerant manifold gauge set
- Vacuum pump
- Leak detector
- Tube cutter and bender
- Electrical multimeter
- Torque wrench set
Step-by-Step Installation
- Site Preparation: Select a location with proper clearance for airflow and service access on a solid, level foundation.
- Remove Shipping Materials: Remove all protective covers, shipping bolts, and packaging materials from the HVAC unit.
- Install Refrigerant Lines: Connect copper refrigerant lines between indoor and outdoor units using proper brazing techniques.
- Electrical Connections: Connect to properly sized circuit breakers with correct voltage (208-230V) and follow local electrical codes.
- Drain Line Installation: Install condensate drain line with proper slope and trap to ensure proper drainage.
- System Evacuation: Evacuate the system to 500 microns or less to remove moisture and non-condensables.
- Charge Refrigerant: Charge with correct type and amount of refrigerant as specified on the unit nameplate.
- Test Run: Start system and check for proper operation, temperature differentials, and verify no leaks exist.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not turning on | Power issue, tripped breaker, faulty thermostat | Check power supply, reset breaker, verify thermostat settings |
| Poor cooling/heating performance | Dirty filters, low refrigerant, blocked airflow | Clean filters, check refrigerant charge, clear obstructions |
| Unit freezing up | Dirty filters, low airflow, refrigerant issue | Clean filters, check fan operation, verify proper charge |
| Water leakage | Clogged drain line, improper installation, frozen coil | Clear drain line, check installation slope, defrost system |
| Unusual noises | Loose parts, debris in fan, failing motor | Tighten components, clean fan blades, check motor bearings |
| Frequent cycling | Dirty filters, oversized unit, thermostat issues | Clean filters, verify proper sizing, check thermostat location |
