Frequently Asked Questions

What technical details should be provided when selecting this HVAC screw compressor for a system retrofit?

Please specify your required cooling capacity, evaporating and condensing temperatures, refrigerant choice, and site power supply specifications.

What piping requirements should be followed during physical installation?

Align connection lines with the 80.0 mm discharge and 105.5 mm suction ports, install rigid vibration absorbers, and confirm discharge check valve operation to prevent refrigerant backflow upon shutdown.

What essential checks are required before initial commissioning?

Verify that the 19 dm³ oil charge level is within sight glass range, confirm correct control module wiring for the INT69 SNY unit, and ensure the crankcase heater has energized for adequate time before startup.

What routine maintenance practices ensure long-term operational reliability?

Inspect the 100 µm suction filter for pressure drop, check oil cleanliness and differential pressure, and verify motor overload safety circuits during scheduled maintenance cycles.
