15.0 Checking and Changing the Lubricating Oil (and Filter on Tropical Plus)
During the compressor’s initial break-in period the original oil (and filter) must be changed after the
first 50 hours . After the initial change, the oil (and filter) must be changed every 250 hours of use or
annually, whichever comes first.
HP Compressor Lubricant: Only use lubricants rated for use with Breathing Air such as Nuvair 455
TM
Synthetic Food Grade Lubricant or Nuvair 751. Never mix Compressor Lubricants. Nuvair
Compressors are shipped with Nuvair 455 Synthetic Food Grade Lubricant or Nuvair 751 in the
compressor.
Use only the specified Nuvair Lubricants in this system. The use of incompatible lubricants
presents a risk of fire and/or explosion, and may result in system damage. This can lead to
severe personal injury and death.
Do not carry out these tasks if the compressor has only just shut down; wait for the
compressor to cool. Pressure must be drained before opening LP Fill Plug.
Any oil spilt during the oil/filter change could cause personnel to slip; wear protective
garments and anti-slip footwear and remove traces of oil immediately.
Both oil and filter are classified as special wastes and must therefore be disposed of in
compliance with the anti-pollution laws in force.
All maintenance work must be carried out with the compressor OFF and the power supply
lead unplugged from the main socket.
