Wilkerson L34 User Manual
INSTALLATION
1. Refer to caution above. CAUTION! DEPRESSURIZE BEFORE SERVICING!
2. Install as close as possible to the equipment requiring lubrication.
3. Install the unit with the air flowing through the body in the direction indicated
by the arrow.
4. Install the same pipe-size unit as the pipeline in use.
5. CAUTION! L34 AtoMist
™
Style lubricators CANNOT be filled while unit is
under pressure. MAKE SURE UNIT IS TURNED OFF AND DEPRESSURIZED
BEFORE REMOVING FILL PLUG. Remove fill plug and fill unit. Use only
clean oil, SAE 10 or lighter is best. DO NOT REPRESSURIZE UNIT unless
fill plug, bowl, and bowl guard are in position and the bowl clamp ring is
securely locked in place.
6. The rate of oil delivery can be controlled by turning the adjusting screw
counterclockwise for more oil and clockwise for less oil delivered. To adjust
this type of lubricator, first reduce the airflow to the airflow to minimum
scfm requirement, then set the oil drip rate so the desired amount of oil is
delivered to the point of use. The more the airflow increases, the more oil
you will need, and the you will automatically receive. Ordinarily, adjust
lubricator so that, for every 33 scfm of air being used. one drop of oil per
minute passes through the sight dome; e.g., for 165 scfm, adjust for five
drops per minute; 330 scfm, 10 drops per minute, etc.
7. DO NOT OVERFILL BOWL; OIL LEVEL MUST REMAIN BELOW
CLASSIFIER; UNIT WILL NOT FUNCTION IF OVERFILLED.
8. Maximum pressure and temperature ratings are: 150 psig (10,3 bar) and
125°F (55°C) for units with transparent plastic bowls and 200 psig (13,8
bar) and 175°F (79°C) for units with metal bowls.
MAINTENANCE
1. The lubricator should remain trouble-free given clean operating conditions.
Contaminants from dirty oil can collect on bottom of bowl or on siphon tube
inlet filter. After tapping filter or bowl on a hard surface, use an air gun to blow
out residual dirt.
2. IF OIL DELIVERY RATE DROPS, clean lubricator. Shut off air supply and
reduce pressure inside lubricator to zero. Remove adjusting screw, clean
needle and seat in body. Inspect and clean passage from needle seat down
into siphon tube adapter.
3. OIL NOT SPRAYING ONTO RECLASSIFIER. Mist generator may be
plugged. Turn off air supply and remove fill plug to vent unit. Remove bowl,
bowl guard and clamp ring. Disassemble reclassifier and, using a screwdriver,
pry out misting nozzle and clean dirt from holes. Reassemble unit. DO NOT
PRESSURIZE UNIT until fill plug, bowl, and bowl guard are in position and
clamp ring is securely locked in place.
4. Drain off contaminants that collect in bottom of bowl.

DO NOT PLACE PLASTIC BOWL UNIT IN SERVICE
WITHOUT METAL BOWL GUARD INSTALLED.
Plastic bowl units are sold only with metal bowl guards. To minimize the danger of flying
fragments in the event of plastic bowl failure, the metal bowl guards should not be
removed. If the unit is in service without the metal bowl guard installed, manufacturer’s
warranties are void, and the manufacturer assumes no responsibility of, any resulting
loss.
IF UNIT HAS BEEN IN SERVICE AND DOES NOT HAVE A METAL BOWL GUARD,
ORDER ONE AND INSTALL BEFORE PLACING BACK IN SERVICE.
CAUTION
Certain compressor oils chemicals, household cleaners, solvents, paints and fumes will
attack plastic bowls and can cause bowl failure. Do not use near these materials. When
bowl becomes dirty replace bowl or wipe only with a clean, dry cloth. Reinstall metal
bowl guard or buy and install a metal bowl guard. Immediately replace any crazed,
cracked, damaged or deteriorated plastic bowl with a metal bowl or a new plastic bowl
and a metal bowl guard.
WE CANNOT POSSIBLY LIST ALL HARMFUL SUBSTANCES. SO CHECK WITH A
MOBAY CHEMICAL OR GENERAL ELECTRIC OFFICE FOR FURTHER INFORMATION ON POLYCARBONATE PLASTIC.
Except as otherwise specified by the manufacturer, this product is specifically designed
for compressed air service, and used with any other fluid (liquid or gas) is a misapplication. For example, use with or injection of certain hazardous liquids or gases in the system (such as alcohol or liquid petroleum gas) could be harmful to the unit or result in a
combustible condition or hazardous external leakage. Manufacturers warranties are void
in the event of misapplication, and manufacturer assumes no responsibility for any
resulting loss. Before using with fluids other than air, or for non-industrial applications, or
for life support systems consult manufacturer for written approval.
