5.6 Tips for using
Do not exceed 10 starting/hour. For more frequent starting, install a soft-start device.
Air can be discharged to the atmosphere through a discharge silencer or it can be piped
else-where. Pump performance decreases if the pipelines are too small or too long.
6. Maintenance and spare parts
6.1 Maintenance
All maintenance operations must be carried out with the pump idle, disconnected form
the elec-trical supply, with the pump cold, vented to atmospheric pressure.
Check the oil level through the suitable oil sight glasses (2) periodically. If needed, top it up.
Change the oil every 5000 (Rotant VF805)/10000 (Rotant VF 315) hours of operation,
draining the exhausted oil through the discharge ports (3). Use a oil ISO VG 150.
When changing the oil also check the coupling elastic element, replace it if required.
Used oil must be disposed of according to local regulations.
If there is an external inlet filter, keep it cleaned to allow full pump performance.
6.2 Spare parts
When ordering spare parts, always state the pump model, serial number, year of produc-
tion, electric motor characteristics (manufacturer’s name, model, kW, V, Hz), position
reference on the spare parts list, description and quantity needed.
7. Lubricants
Synthetic oil recommended for generic use
Use the synthetic oil for compressors.
