WARNING

!

To avoid unpredictable system behavior that can cause personal injury
and property damage:

• Disconnect electrical supply (when necessary) before installation,
servicing, or conversion.

• Disconnect air supply and depressurize all air lines connected to
this product before installation, servicing, or conversion.

• Operate within the manufacturer’s specified pressure, temperature,
and other conditions listed in these instructions.

• Medium must be moisture-free if ambient temperature is below
freezing.

• Service according to procedures listed in these instructions.

• Installation, service, and conversion of these products must be
performed by knowledgeable personnel who understand how
pneumatic products are to be applied.

• After installation, servicing, or conversion, air and electrical supplies
(when necessary) should be connected and the product tested for
proper function and leakage. If audible leakage is present, or the
product does not operate properly, do not put into use.

• Warnings and specifications on the product should not be covered
by paint, etc. If masking is not possible, contact your local
representative for replacement labels.

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

1. Refer to warning.

2. Install as close as possible to the equipment which is being lubricated.

3. Install the unit with the air flowing through the body in the direction
indicated by the arrow.

4. Install a unit with the same pipe size as the line in use.

OPERATION

1. The maximum pressure and temperature ratings are: transparent
plastic bowl, 150 PSIG (10,3) and 125°F(51,7°C); metal bowls, 200
PSIG (13,8 bar) and 175°F (79,4°C0.

2. The lubricator may be filled under pressure by removing the fill plug
and pouring the oil into the bowl through the fill port. The bowl may be
taken off after the fill plug is removed if a more rapid fill is required. DO
NOT replace the fill plug until the bowl and the bowl guard are in
position and securely locked in place. NOTE: As the fill plug is removed,
the air pressure in the bowl will be relieved.

3. Use clean oil preferably SAE 10 or lighter. The rate of oil delivery may
be controlled by turning the adjusting screw counterclockwise for
more and clockwise for less oil delivered. This L26 lubricator delivers
all the oil downstream that passes through the sight dome. The oil
delivery rate will change automatically to deliver more oil during higher
airflows and less oil for airflows lower than the one at which the
setting was made.

Doc.# 83179000, ECN# 060135, Rev. 1

MAINTENANCE

1. Given clean operating conditions, this unit will be trouble-free.

2. IF OIL DELIVERY RATE DROPS, the lubricator should be cleaned.
Shut off air supply and reduce pressure to zero. Remove Flow­Guide® variable orifice screw and clean its passage with a small
wire. Check orifice screw’s bore for contaminants and clean it if
necessary. Be sure that the passageway from the sight dome cavity
into Flow-Guide® variable orifice post is open. Remove adjusting
screw, clean needle and seat in body. Inspect and clean passage
from needle seat to siphon tube adapter.

3. Drain off contaminants that collect in bottom of bowl and wipe it clean
with a soft cloth.

4. Lubricate o-rings with Dow Corning 200 silicone oil or equivalent
before assembly.

5. Do not pressurize the unit until the bowl and bowl guard are in position
and locked in place.
