"name": "What electrical requirements and noise levels should I consider?",
"acceptedAnswer": {
"@type": "Answer",
"text": "The AOVH-20 uses a TEFC fan motor (around 1/2 HP) typically rated for 115/208–230 V, single-phase, 60 Hz, operating in the 90 dB(A) range. Always confirm electrical specs on the motor nameplate and size wiring and protection accordingly."

"name": "How should I install and maintain the AOVH-20 to ensure maximum cooling performance?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Install the cooler horizontally with clear airflow, pipe oil from the lower to the upper port, and use flexible hoses to reduce vibration. Keep the fins clean, ensure proper oil filtration, and follow motor lubrication and maintenance guidelines to maintain long-term cooling efficiency."
