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 receiver--separa-
tor tank cover and terminates at the compressor air-
end 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.
Excessive oil carry--over may be caused by an oil--
logged separator element. Do not replace element
without first performing the following maintenance pro-
cedure:
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.
5. Wipe the area clean using Duponts 3900S.
6. Blow and tack the area to be painted.
7. Apply a smooth coat of Duponts 1854S
Tuffcoat Primer to all bare metal areas and
allow to dry.
8. Apply 2 medium -- wet coats of Duponts 222S
Adhesion Promoter over the entire area to be
painted, with a 5 minute flash in between coats.
9. To apply the texture coat, use Duponts 1854S
Tuffcoat Primer. The proper technique to do this
is to spray the Tuffcoat Primer using a pressure
pot and use about 2--5 pounds of air pressure.
This will allow the primer to splatter causing the
textured look. Note: you must be careful not to
put too much primer on at one time, this will
effect the amount of texture that you are trying
to achieve. Allow the texture coat to flash for 20
minutes or until dry to touch.
10. Apply any of Duponts Topcoat Finishes such as
Imron
t
or Centari
t
according to the label
instructions.
Note: To re--top coat the textured surfaces when sheet
metal repairs are not necessary, follow steps 1,
2, 4, 5, 6, 8 and 10.
