Scavenge Line
WARNING
!
High pressure air can cause severe injury or death from hot oil and flying parts.
Always relieve pressure before removing caps, plugs, covers or other parts from
pressurized air system.
The scavenge line originates at the manifold and terminates at the compressor airend near the
oil filter element. An orifice check valve is located on the scavenge tube.
Once a year or every 1000 hours of operation, whichever comes first, replace the separator
element and clean the scavenge orifice/check valve.
NOTE: Excessive oil carry-over may be caused by an oil-logged separator element. Do not
replace element without first performing the following maintenance procedure:
1. Check oil level. Maintain as indicated earlier in this section.
2. Thoroughly clean scavenge line, any orifice and check valve.
3. Assure minimum pressure valve/orifice is operational.
4. Run unit at rated operating pressure for 30 to 40 minutes to permit element to clear itself.
Exterior Finish Care
This unit was painted and heat cured at the factory with a high quality, thermoset polyester
powder coating. The following care will ensure the longest possible life from this finish.
1. If necessary to remove dust, pollen, etc. from housing, wash with water and soap or dish
washing liquid detergent. Do not scrub with a rough cloth, pad, etc.
2. If grease removal is needed, a fast evaporating alcohol or chlorinated solvent can be used.
Note: This may cause some dulling of the paint finish.
3. If the paint has faded or chalked, the use of a commercial grade, non-abrasive car wax
may partially restore the color and gloss.
Field Repair of Texture Paint
1. The sheet metal should be washed and clean of foreign material and then thoroughly
dried.
2. Clean and remove all grease and wax from the area to be painted using Duponts 3900S
Cleaner prior to sanding.
3. Use 320 grit sanding paper to repair any scratches or defects necessary.
4. Scuff sand the entire area to be painted with a red scotch brite pad.
