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 wh o 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 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 hydro-carbons, ketones,
esters, and certain alcohols. They should not be used in air systems where
compressors are lubricated with fire resistant fluids such as phosphate
esters and di-esters types. In areas where polycarbonate bowls are
exposed to high temperatures or atmospheres containing vapors or fluids,
which are damaging to plastic, use metal 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 cleaning agents such as acetone, benzene, carbon

tetrachloride, gasoline, toluene, etc., which are damaging to this plastic.

Bowl gua rds are recommended for add ed protection of
polycarbonate bowls where chemical attack may occasionally
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

(Refer to Pictorial on Following Page)

1. Filling — The Mist lubricator can be filled without turning off
the upstream pressure. Slowly remove the fill plug by turning
counterclockwise. This allows the bowl pressure to vent.

Suggested lubricant: F442

Petroleum based oil of 100 to 200 SUS 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. If leakage occurs, DO NOT
OPERATE — conduct repairs again.The lubricator is now
ready for setting.

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

1" Lubricator Series 2L300C

Leaner — Clockwise

Richer — Counterclockwise

By counting the number of drops per minute in the sight dome,

you can adjust to your requirements.

Mist lubricator — Every drop visible in the sight dome goes

downstream.

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.

NOTE: This is a constant density type lubricator which

delivers a constant ratio of oil air flow. Therefore, if
air flow incr eases o r decreases, o il deli very will be
adju s t e d propor tionately. ONLY IF A DI F FERENT
RATIO IS DESIRED SHOULD YOUR ADJUSTMENT KNOB
SETTING BE CHANGED AFTER YOUR INITIAL SETTING.

4. To replace fill plug, drip control, & 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.
