CAUTION
Polycarbonate bowls, being transparent and tough, are ideal for use with
Filters and Lubricators. They are suitable for use in normal industrial
environments, but should not be located in areas where they could be subjected
to direct sunlight, an impact blow, nor temperatures outside of the rated
range. As with most plastics, some chemicals can cause damage.
Polycarbonate bowls should not be exposed to chlorinated hydrocarbons,
ketones, esters and certain alcohols. They should not be used in air systems
where compressors are lubricated with fire-resistant fluids such as phosphate
ester and di-ester types.
Metal bowls are recommended where ambient and/or media conditions are
not compatible with polycarbonate bowls. Metal bowls resist the action of
most such solvents, but should not be used where strong acids or bases are
present or in salt laden atmospheres. Consult the factory for specific
recommendations where these conditions exist.
TO CLEAN POLYCARBONATE BOWLS USE MILD SOAP AND WATER
ONLY! DO NOT use cleansing agents such as acetone, benzene, carbon
tetrachloride, gasoline, toluene, etc., which are damaging to this plastic.
Bowl guards are recommended for added protection of polycarbonate bowls where
chemical attack may occur.

Installation
L508 Lubricators are individually tapped (NPT) to allow direct
mounting to piping. Before installing, blow out pipe line to remove
scale and other foreign matter. This unit has DRYSEAL pipe
threads; use pipe compound or tape sparingly to male threads
only. Install units in pipe line so that flow is into port stamped
“IN” on body. Install as near as possible to equipment serviced.
Lubricant
For average conditions, the use of high quality SAE #10 (S.U.V.
150-200 SEC @ 100°F) oil is recommended. Other lubricants,
as specified by the maker of the equipment to be lubricated, may
be used if not heavier than SAE #40 (S.U.V. 800 SEC @100°F).

factory due to pre-drilled holes in lubricator head.
Service Kits / Parts AvailableFilling
L508 Lubricators may be filled only under no pressure. To fill
the lubricator, the air supply must be shut off and the remaining
pressure in the system bled down to zero pressure. A long
spout oil can must be used. Slowly remove fill plug and insert
tip of spout to bottom of fill port recess. Fill to within 1/2" of top
of bowl using correct oil.
Adjustment
The adjustment knob is factory set so that, when turned fully
clockwise, no oil is delivered to the venturi for atomization, and
equipment is not being lubricated. To initially adjust oil drip rate,
turn on the air, start flow and set knob to obtain the desired drip
rate, which is visible through the sight dome. After system
reaches normal operating temperature, fine tune the drip rate
as needed. As a start, one to two drops per minute is suggested,
correct lubrication being a matter of experience and demand.
Clockwise rotation of knob decreases oil feed rate. To check
lubrication, hold a thumbnail or mirror near the equipment
exhaust. A heavy film indicates over-lubrication and the drip
rate should be reduced by turning knob to a lower setting. After
final setting has been achieved, the knob may be removed to
make the adjustment mechanism tamper resistant.
Cycling Applicator
If the lubricator is to be used in a cycling application, the
conditions must be as follows:
The lubricator must stay pressurized during on AND off cycles.
On cycle time must be at least 15 seconds, and the flow rate
during each cycle must be at least 2 SCFM.
Maintenance - Cleaning
If both air and oil are kept clean, and the oil level never allowed
below end of tube in the bowl, the lubricator should provide long
periods of unattended service. Cessation of oil dripping through
the sight dome, irrespective of knob adjustment, is an indication
that cleaning is necessary. To clean, it is not necessary to
remove lubricator from the line. Depressurize and disassemble
using the drawing as a guide. In most instances, cleaning is
needed only in the oil metering area. Pull off adjusting knob,
unscrew sight dome assembly, remove inner drip spout and
clean with household soap. PLASTIC BOWLS AND SIGHT
DOME MUST BE CLEANED WITH HOUSEHOLD SOAP ONLY.
