DISASSEMBLY
1. Lubricator can be disassembled without removal from air
line.
2. Shut off inlet pressure. Reduce pressure in inlet and
outlet lines to zero.
3. Turn reservoir counterclockwise and remove from body.
4. Disassemble in general accordance with the item
numbers on exploded view. Do not remove manual drain
unless replacement is necessary. Remove and replace
only if drain malfunctions.Do not attempt to remove
siphon tube on early models, as these parts are
permanently assembled.
CLEANING
1. Clean plastic reservoir with warm water only. Clean other
parts using warm water and soap.
2. Dry parts. Blow out internal passages in body with clean,
dry compressed air.
3. Inspect parts. Replace parts found to be damaged. If
plastic reservoir shows signs of cracking or cloudiness,
replace with a metal reservoir.
ASSEMBLY
1. Lubricate seals and o-rings with o-ring grease. Apply a
small amount of anti-seize lubricant to full length of
threads on metal reservoirs.
2. Assemble lubricator as shown on exploded view.
3. Torque Table N-m (Inch-Pounds)

WARNING
These products are intended for use in industrial
compressed air systems only. Do not use these products
where pressures and temperatures can exceed those listed
under Technical Data.
Polycarbonate plastic reservoirs can be damaged and
possibly burst if exposed to such substances as certain
solvents, strong alkalies, compressor oils containing ester-
based additives or synthetic oils. Fumes of these
substances in contact with the polycarbonate reservoir,
externally or internally, can also result in damage. Clean
with warm water only
Use metal reservoir in applications where a plastic
reservoir might be exposed to substances that are
incompatible with polycarbonate.
In lubrication applications some oil mist may escape
from the point of use to the surrounding atmosphere.
Users are referred to safety and health standards for
limiting oil mist contamination and utilization of protecting
equipment
Before using these products with fluids other than air,
for nonindustrial applications, or for life-support systems
consult Norgren.

INSTALLATION
1. Shut-off air pressure. Install lubricator in air line -
● vertically (reservoir down),
● with air flow in direction of arrow on body,
● downstream of filters and regulators,
● upstream of cycling valves,
● as close as possible to the device being lubricated,
2. Connect piping to proper ports using pipe thread sealant
on male threads only. Do not allow sealant to enter
interior of unit.
3. Turn reservoir fully clockwise into body before
pressurizing.
FILL RESERVOIR WITH OIL
Shut off inlet air pressure and reduce pressure in reservoir
to zero. Remove reservoir and fill with a good quality, light,
misting type oil for compressed air tools. See Norgren
publication N/AL.8.900.935. Fill to maximum fill line on
reservoir. DO NOT OVERFILL. Reinstall reservoir and turn
fully clockwise into body before pressurizing. Tighten as
specified in Torque Table.
ADJUSTMENT
1. Turn on system pressure.
2. Adjust lubricator drip rate only when there is a constant
rate of air flow thru the lubricator. Monitor drip rate thru
sight feed dome (3, 14).
3 Determine the average rate of flow thru the lubricator.
Turn red rotator in sight feed dome to obtain the
recommended drops per minute. See Drip Rate Chart.
Turn rotator counterclockwise to increase and clockwise
to decrease the drip rate. Total travel of rotator is 320°.
4. Monitor the device being lubricated for a few days
following initial adjustment. Adjust the drip rate if the oil
delivery at the device appears either excessive or low.

NOTES FOR CURRENT AND EARLY MODELS
Current reservoirs use a lip on the reservoir
inside diameter and early reservoirs use a lip on
the reservoir outside diameter to retain reservoir
o-ring. Services kit contains current and early
reservoir o-rings. The larger of the o-rings is used
on the early reservoir.
Reservoirs are not interchangeable.
Reservoirs with outside o-ring lip must be used
on early bodies, and reservoirs with inside o-ring
lip must be used on current bodies.
