A: The main motor operates on a standard 400V/3Ph/50Hz or 460V/3Ph/60Hz power supply, while the built-in crankcase heater requires a dedicated 275W – 230V – 50/60Hz supply to prevent refrigerant migration during idle periods.
A: Installers must match the 105.5 mm (4-1/8") suction connection and 80.0 mm (3-1/8") discharge line accurately, ensuring proper support and vibration isolation to eliminate excessive stress on the shut-off valves.
A: Check that the oil charge reaches the specified level visible in the sight glass using the approved lubricant type (such as S001 for R22 or S002 for HFC blends), and verify filter cleanliness before startup.
A: Inspect motor winding and discharge gas temperature sensors, verify correct three-phase supply voltage sequence, check for phase imbalance, and ensure adequate cooling superheat before resetting the module.
