L50 Injection Lubricator - Parker

Installation:
General Installation Oil Supply & Reservoir Options
It is recommended that the L50 be installed immediately
downstream of a particulate/moisture removal air line
filter, and a pressure regulator, in order to insure long
life and trouble-free performance. In most cases, it is
desirable to use the 1/8" diameter nylon capillary tubing
to deliver oil down the inside of the air supply pipe, or
hose, to the point of use. In these cases, thread the
capillary tubing into the pipe prior to assembling to the
outlet port of the lubricator. If the capillary tubing is
inserted into standard pipe, cut the capillary tubing so
that it is approximately 6" from the inlet port of the air
device. If the tube is inserted into a flexible hose, cut
the capillary approximately 10% shorter than the hose
to allow for diameter expansion and resultant shortening
of air hose length. After the capillary tube is installed,
connect the lubricator inlet port to the air supply line,
connect the capillary tube to the lubricator barbed oil
outlet, and then connect downstream air piping.

Integral Reservoir (“R” option)
The L50 is available with an integral 10 oz. reservoir.
The unit must be oriented so that the reservoir remains
in the vertical position, with the vent and fill plugs on
the top. To fill the unit, remove the large fill plug with a
screwdriver and pour oil into the unit. The petcock style
vent, on top of the reservoir, must be in the open position
for the unit to work. If using with a pressurized or gravity
feed external oil supply, the vent must remain closed.
External Reservoir (non-pressurized)
When installing a lubricator for use with an external
reservoir, the lubricator may be oriented in any position.
The plumbing from the reservoir must be connected to
the oil port on the lubricator closest to the top (ceiling).
The plumbing from the reservoir must not have any loops
or bends that would allow air to be trapped.
External Oil Supply (pressurized)
When installing a lubricator for use with an external
reservoir, the lubricator may be oriented in any position.
The plumbing from the reservoir must be connected to
the port on the lubricator closest to the bottom (floor).
A vent, or petcock, must be placed in the port closest
to the top (ceiling) to allow purging of air from the oil
supply. It is recommended that a small reservoir capable
of handling 3 or 4 cubic inches be connected to the port
closest to the top (ceiling) to trap any air bubbles from
the oil supply. It is recommended that a shut-off valve
and strainer be installed in the oil supply line as close to
the L50 as possible.
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.
