Unpack unit and inspect for shipping damage. Select a suitable outdoor location.
WARNING! Installation must be performed by a qualified HVAC technician in accordance with national and local codes. Incorrect installation can cause property damage, personal injury, or death. Handle refrigerant responsibly.
After installation, perform these steps to commission the system.
CAUTION! Do not operate without proper refrigerant charge or with blocked airflow. This can lead to compressor failure.
Primary control is via the indoor thermostat. Unit has internal safeties and a control board.
Thermostat Operation: Set to COOL mode and desired temperature. Fan can be set to AUTO (cycles with compressor) or ON (continuous).
Unit Controls: - High/Low Pressure Switches: Automatically shut off compressor if refrigerant pressure is outside safe limits. - Compressor Crankcase Heater: Energized when unit is off to prevent refrigerant migration and oil slugging. - Time Delay: Built-in 5-minute time delay protects compressor from short cycling.
Normal Operation Sounds: You will hear the fan start, followed by the compressor. A slight hiss after shutdown is normal (pressure equalization).
This outdoor unit must be connected to a matching indoor coil (evaporator) and air handler or furnace.
Tip: Label all wires during installation for easier future service.
Regular maintenance ensures efficiency, longevity, and safe operation. Disconnect power before servicing.
WARNING! Do not insert fingers or tools into fan grill while power is connected. The fan can start automatically.
Built-in protection devices: High and low-pressure switches, compressor thermal overload, time delay, and crankcase heater. The unit will shut down if a fault is detected. Consult a technician if unit repeatedly trips on safety.
Cooling Season: Clear area around unit, ensure unobstructed airflow, check/clean air filter at indoor unit monthly.
Off-Season (Winter): Consider installing a waterproof cover over the top of the unit to keep out debris and ice, but ensure sides remain open to prevent moisture trapping and rodent habitation. Do not wrap tightly in plastic.
CAUTION! Never use a pressure washer to clean the coil, as fins can be damaged. Keep lawn chemicals and sprinklers away from the unit cabinet.

| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Unit does not start | Power loss, tripped breaker, blown fuse, thermostat setting, time delay. | Check disconnect and breaker. Ensure thermostat is in COOL, set below room temp. Wait 5 mins after power restore. |
| Fan runs, compressor does not | Low refrigerant charge (trips low-pressure switch), faulty capacitor, compressor overload. | Call for professional service to check charge and electrical components. |
| Reduced cooling/ice on lines | Dirty air filter, low refrigerant, restricted airflow (dirty coil or blocked registers). | Replace indoor filter. Clean outdoor coil. If ice present, turn system OFF, fan ON to thaw, then call for service. |
| Unit cycles on/off frequently | Dirty filter/coil, thermostat location (in sun or draft), oversized unit, low charge. | Clean filter and coil. Verify thermostat location is proper. May require professional evaluation. |
| Unusual noise (rattling, grinding) | Loose panel, debris in fan, failing fan motor or compressor. | Turn unit OFF. Check for loose screws/panels. Remove visible debris. If noise persists, call for service. |
Note: Most repairs require a certified HVAC technician. Do not attempt to repair refrigerant circuit or major electrical components.
