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 the warning.
2. Install as close as possible to the equipment requiring lubrication.
3. Install the unit with the air moving through the body in the direction
indicated by the arrow.
4. Install a unit with the same pipe-size as the line in use. Avoid using
fittings, couplings, etc., that restrict the airflow or baffle the oil out of
the air at the lubricator outlet.
5. The lubricator cannot be filled without first shutting off air pressure and
venting the bowl. (Remove fill plug.) The bowl may be taken off after
the fill plug is removed if a more rapid fill is required. DO NOT
PRESSURIZE until the fill plug, bowl and bowl guard are in position
and locked into place.
6. The rate of oil delivery may be controlled by turning the adjusting screw
counterclockwise for more and clockwise for less oil delivery. Adjust
the lubricator by reducing the airflow to the minimum scfm required
and setting the oil drip rate so that the desired amount of oil is delivered
to the point of use. The more the airflow increase, the more oil you will
need, and the more you will automatically receive. Ordinarily, adjust to
tone drop per minute of oil as seen through the sight dome or each 33
scfm (56 Nm 3/h) of air being used; e.g., for 50 scfm (84 Nm3/h), adjust
for 1.5 drops per minute; 100 scfm (168 Nm 3/h), 30 dpm; etc.
7. DO NOT OVERFILL BOWL; OIL LEVEL MUST BE BELOW THE
RECLASSIFIER
MAINTENANCE
1. Given clean operating conditions, this unit will be trouble-free.
Contaminants from dirty oil may collect on the siphon tube inlet filter,
requiring the filter to be cleaned by tapping on a hard surface and
blowing off with an air blow gun.
2. IF THE OIL DELIVERY RATE DROPS, the lubricator should be
cleaned.Shut off air supply and reduce pressure in unit to zero. Remove
the adjusting screw and clean the needle and the seat in the body.
Inspect and clean the passage from the needle seat down into the
adapter.
3. OIL NOT SPRAYING ONTO RECLASSIFIER—In addition to the above
possible reasons,the mist generator might be plugged. Turn off and
vent air pressure through the fill plug, then remove the bowl,
disassemble the reclassifier and pry out the missing nozzle with a
screwdriver or a knife blade, clean in kerosene and blow out holes with
air blow gun
4. Drain off any contaminants which collect in the bottom of the bowl.
