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.

The lubricator should be installed with reasonable accessibility
for service whenever possible. Keep pipe or tubing lengths to
a minimum with inside clean and free of dirt and chips. Pipe
joint compound should be used sparingly and applied only to
the male pipe – never into the female port. Do not use PTFE
tape to seal pipe joints – pieces have a tendency to break off
and lodge inside the unit, possibly causing malfunction.

2.

Install lubricator so air flows in the direction of arrow on body.

3. Installation should be upstream of the device it is to lubricate
(valve, cylinders, tool, etc.).

Operation and Service

1. The inlet pressure of the Atomist lubricator must be turned
off and depressurized before the fill plug (brass) is removed.
Turn counterclockwise to remove. Fill to oil level line.

Use a petroleum based oil of 100 to 200 SSU viscosity at
100°F and an aniline point greater than 200°F. (Mobil DTE24
and Sun Company Sunvis 932 are good examples). Do not
use oils with adhesives, compound oils containing solvents,
graphite, detergents or synthetic oils.

2. Replace the fill plug (by turning clockwise) and seat firmly.
Excessive torque is not required. Turn on air supply . If leakage
occurs, DO NOT OPERATE — conduct repairs again. The
lubricator is now ready for setting.

NOTE: This is a constant density type lubricator which delivers a constant

ratio of oil to air flow. Therefore, if air flow increases or decreases, oil
delivery will be adjusted proportionately. ONLY IF A DIFFERENT RATIO
IS DESIRED SHOULD YOUR ADJUSTMENT KNOB SETTING BE
CHANGED AFTER YOUR INITIAL SETTING.

4. To replace fill plug, drip control, and service lubricator:
A. Turn off air supply and depressurize the unit.
B. Refer to pictorial for servicing and torque values.
C. Turn on air supply and check lubricator for leakage. If

leakage occurs, DO NOT OPERATE — conduct repairs
again.

Lightly grease with provided lubricant. (Silicone free)
Inspect for nicks, scratches, and surface imperfections.

If present, reduced service life is probable and future
replacement should be planned.

Clean with lint-free cloth.

3. Oil delivery adjustment — To adjust oil delivery, turn
adjustment knob on top of the lubricator.

Leaner — Clockwise
Richer — Counterclockwise

By counting the number of drops per minute in the sight
dome, you can adjust to your requirements.

Atomist lubricator — Approximately 3% of the droplets visible
in the sight dome go downstream; adjust drip rate accordingly.
Consult oil delivery conversion chart.

Generally, one drop per minute downstream for every
10 - 15 SCFM flow is satisfactory.

25 drops per minute equals one (1) ounce per hour - volume
of oil passing through the sight dome.
