Product Technologies and Features
The Durastar DRA1U18S1B condenser incorporates advanced technologies for efficient and reliable performance:
- Variable Speed Inverter Compressor: Utilizes an electronic expansion valve and a variable speed compressor to precisely regulate refrigerant flow, optimizing energy consumption and maintaining consistent, accurate temperatures.
- Auto Restart: In the event of a sudden power failure, the indoor unit's auto-restart module will automatically restore previous settings once power returns.
- Quiet Operation: Both the outdoor and indoor units are designed with brushless direct current fan motors to minimize electrical and mechanical sound during operation.
- Low Ambient Operations: This outdoor unit is capable of cooling operations down to 5 degrees Fahrenheit (-15 degrees Celsius) and heating operations down to -13 degrees Fahrenheit (-25 degrees Celsius).
- Included Base Pan Heater: Features a defrost function that effectively removes frost from the condenser coil in frigid conditions, ensuring continuous heating performance.
- Anti-Corrosive Fin Coating: The condenser coils are treated with an anti-corrosive coating to enhance longevity, reliability, and prevent corrosion, thereby improving overall durability.

Operating Instructions
The Durastar DRA1U18S1B condenser unit operates in conjunction with your indoor evaporator unit. All operational controls, such as setting temperature, mode (cooling/heating), and fan speed, are managed via the indoor unit's remote control or wall thermostat.
Once the indoor unit is activated, the outdoor condenser will automatically engage to provide the desired cooling or heating capacity based on the system's settings. The variable speed inverter compressor will adjust its output to efficiently maintain the set temperature.
In case of a power outage, the Auto Restart feature will ensure the system resumes operation with its previous settings once power is restored.
Maintenance
Regular maintenance helps ensure the longevity and efficiency of your Durastar mini-split condenser. While professional maintenance is recommended annually, some basic checks can be performed by the user:
- Keep Clear: Ensure the area around the outdoor unit is free from leaves, dirt, grass clippings, and other debris that could obstruct airflow.
- Clean Coils: Periodically inspect the outdoor coil fins. If they appear dirty, gently clean them with a soft brush or a garden hose (low pressure). Avoid bending the fins.
- Check for Obstructions: Ensure nothing is blocking the fan or air intake/exhaust vents.
- Drainage: Verify that the condensate drain line (if applicable to the outdoor unit's setup) is not clogged and is draining properly.
- Professional Servicing: Schedule annual professional maintenance to check refrigerant levels, electrical connections, and overall system performance.
The anti-corrosive fin coating helps protect the unit from environmental elements, but regular cleaning is still beneficial.
Troubleshooting
If you experience issues with your Durastar mini-split system, consider the following basic troubleshooting steps before contacting a professional:
- No Power: Check the circuit breaker for the unit. Ensure it has not tripped.
- Indoor Unit Not Operating: Confirm the indoor unit is powered on and its remote control batteries are functional.
- Insufficient Cooling/Heating:
- Check if the air filters in the indoor unit are clean.
- Ensure no windows or doors are open, allowing conditioned air to escape.
- Verify that the outdoor unit's coils are not blocked by debris.
- Unusual Noises: Minor operational sounds are normal. If you hear loud or unusual noises, power off the unit and contact a professional.
For any issues beyond these basic checks, it is strongly recommended to contact a qualified HVAC technician. Do not attempt complex repairs yourself.
