Do not carry out any maintenance tasks if the compressor has just shut down.
Wait for the compressor to cool to avoid skin burns.
Special attention needs to be given to the arrangement of the four LP Air Filtration Elements and
Bowls. Properly reinstall each Element and Bowl to the correct Housing. Improper sequence can
cause damage to downstream components

LP Filtration (Optional Diver 3 stage Filtration Package)
Three stages of Hankison LP filtration are used to produce Grade D air:
1) Particle Removal to 1 micron
2) Coalescing & Water/Oil Vapor Removal to 0.01 micron
3) Oil Vapor Removal to 0.003 PPM
14.1 Filtration Inspection
Open each Filter and inspect as follows:
1. Inspect Bowl for the presence of moisture. A high level of moisture build-up in the HF7 or HF5
Filter indicates improper operation of auto-drain floats. Any evidence of moisture in the HF1 Filter
indicates the air is not cooling properly and moisture is not properly being removed. Excess
moisture will prevent the final filter from operating properly.
2. Inspect Elements for any unusual degradation or wetness. Element degradation can indicate more
serious problems. Contact Nuvair for assistance.
Be sure that all pressure has been relieved from the system prior to opening any
filtration canister. Failure to vent pressure from the system prior to opening the
canister can lead to serious personal injury or death.
