Frequently Asked Questions
What technical data is required when requesting model selection for a screw compressor HVAC project?
Please provide required cooling capacity, operating evaporation and condensation temperatures, refrigerant choice, and electrical power supply specifications.
What installation precautions should be taken for suction and discharge piping?
Ensure pipe dimensions match the 80.0 mm discharge and 105.5 mm suction connections, install proper piping supports to isolate vibration, and verify check valve positioning to prevent liquid backflow.
What pre-start checks are mandatory prior to initial commissioning?
Confirm that the 19 dm³ oil level is clearly visible in the sight glass, verify proper signal wiring to the INT69 SNY protection unit, and allow the crankcase heater sufficient time to pre-heat before starting.
What maintenance steps help preserve operational stability during continuous duty?
Periodically inspect suction filter cleanliness, monitor oil pressure differential across internal flow paths, and test thermal protection trip circuits during scheduled maintenance.
