FAQ
Q: What electrical supply requirements and heater ratings must be accommodated in the control panel for the SRC-S(W)-603 (SRC-S-603-L4) compressor?

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.

Q: What piping layout factors should be considered when connecting suction and discharge lines to this model?

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.

Q: How should the oil level and initial lubrication be verified prior to commissioning?

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.

Q: What diagnostic steps should technicians follow if the INT69 SNY module triggers a safety lockout?

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.
