Frequently Asked Questions

What details should be confirmed before selecting this screw air conditioning compressor for a project?

Please provide required cooling capacity, operating evaporating and condensing temperatures, refrigerant type, and project site electrical specifications.

What piping precautions should be observed when installing the SRC-S(W)-353?

Match connections with the 80.0 mm discharge and 92.5 mm suction lines, install adequate pipe supports to minimize vibration, and ensure the discharge check valve operates smoothly to prevent backflow upon shutdown.

What safety checks are mandatory prior to initial start-up?

Confirm that the 14 dm³ oil charge level is within range, verify wiring of the INT69 SNY protective module, and ensure the 275W crankcase heater has energized for sufficient time.

How should maintenance teams manage routine servicing for this unit?

Periodically check the 100 µm suction filter element for debris, monitor oil pressure differential across internal flow paths, and test thermal protection trip functions during scheduled maintenance.
