Unpack and inspect contents. Place on a level, stable pad (concrete or composite).
WARNING! Installation and service must be performed by a qualified HVAC technician. Disconnect all power before servicing. Follow all local electrical and building codes.
After installation, perform initial startup and system check.
CAUTION! Do not operate without proper refrigerant charge. Incorrect charge can damage the compressor.
Primary control is via the indoor thermostat. Unit has an internal control board with a diagnostic LED.
Thermostat Control: Set mode (COOL, OFF, FAN ON/AUTO), temperature, and fan speed.
Unit Control Board LED: Monitors system status. Steady ON = normal operation. Flash codes indicate specific faults (see Diagnostics section).
No User-Adjustable Settings: Operating parameters (fan delay, pressure limits) are factory-set. Refrigerant charge and airflow must be set by technician at installation.
Proper low-voltage wiring is critical for communication between thermostat, indoor unit, and outdoor unit.
Tip: Use a minimum 18 AWG thermostat wire. Ensure wires are not pinched or near high-voltage lines.
For normal operation, use the thermostat. Regular maintenance ensures efficiency and longevity.
WARNING! Do not insert any objects into the fan grille or coil fins. Do not use a pressure washer on the coil.
The control board LED provides fault indications via flash codes.
| LED Flash Pattern | Possible Fault | Description |
|---|---|---|
| 1 Flash | Loss of Charge / Low Pressure | Refrigerant leak, restriction, or faulty switch |
| 2 Flashes | High Pressure | Dirty coil, restricted airflow, overcharge, faulty switch |
| 3 Flashes | Low Voltage or Power Loss | Incorrect voltage, brownout, or wiring issue |
| 4 Flashes | High Discharge Temperature | Low charge, restricted airflow, high ambient temp |
| 5 Flashes | Compressor Overload / Lockout | Electrical fault, mechanical failure, frequent cycling |
| Steady On | Normal Operation | Unit is running or ready |
Note: After a fault is corrected, power to the unit must be cycled (OFF for >1 minute, then ON) to reset the control board.
Keep the outdoor unit clean and unobstructed for optimal performance.
CAUTION! Always disconnect power before performing any cleaning near electrical components.

| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Unit does not start | Power off, tripped breaker, thermostat setting, safety lockout | Check disconnect switch and breakers. Verify thermostat is in COOL mode and set below room temp. Wait 5 minutes for compressor time delay. Check diagnostic LED. |
| Unit runs but does not cool | Dirty filter/coil, low refrigerant, thermostat issue | Replace air filter. Clean outdoor coil. Check for blocked return/supply vents. Call technician to check charge. |
| Unit cycles on/off frequently (short cycles) | Dirty filter/coil, oversized unit, low/high refrigerant charge | Clean filter and coil. Ensure proper airflow. Call technician for system evaluation. |
| Unusual noise (rattling, grinding) | Loose parts, debris in fan, failing motor or compressor | Turn unit OFF. Check for loose panels or debris. Call technician if noise persists. |
| Ice on refrigerant lines or indoor coil | Low airflow (dirty filter/coil), low refrigerant charge | Turn system OFF. Replace filter. Allow ice to melt completely. If problem returns, call technician. |
| Water leakage at indoor unit | Clogged condensate drain line | Clear the drain line and drain pan. Ensure proper slope. |
Reset: For lockout conditions, turn thermostat to OFF, turn off power at disconnect for 1 minute, then restore power and thermostat.
Service: For all technical issues beyond basic homeowner checks, contact a qualified American Standard dealer.
