Frequently Asked Questions
Q: What technical details should be provided when selecting this AC screw compressor for a large-scale HVAC system?
A: Please specify your target cooling capacity, operating evaporation and condensation temperatures, compatible refrigerant type, and site power supply requirements.
Q: What installation precautions should be observed when connecting suction and discharge piping?
A: Ensure pipe alignment matches the 105.5 mm suction and discharge connections, install solid piping supports to minimize vibration stress, and verify check valve placement to prevent reverse rotation at shutdown.
Q: What pre-commissioning steps are required prior to initial startup?
A: Confirm that the 25 dm³ oil charge level is visible in the sight glass, check control loop wiring to the INT69 SNY module, and allow the 275W crankcase heater sufficient time to pre-heat before energizing.
Q: How should maintenance teams manage routine servicing for optimal longevity?
A: Periodically inspect the internal suction filter for pressure drop, monitor oil differential pressure across system flow channels, and test motor thermal protection circuits during scheduled servicing.
