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.
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 op-
erational.
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 coat-
ing. 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--topcoat the textured surfaces when
sheet metal repairs are not necessary,
follow steps 1, 2, 4, 5, 6, 8 and 10.
