IMI NORGREN L64C, L64M Installation & Maintenance Instructions Manual
ADJUSTMENT
1. Turn on system pressure.
2. Adjust lubricator drip rate only when there is a constant
rate of air flow through the lubricator. Monitor drip rate
through sight feed dome (3).
3. Oil-Fog Lubricators - Determine the average rate of flow
through the lubricator. Turn green knob (3) to obtain one
drop per minute for each 5 dm
3
/s (10 scfm). For
example, if the average flow is 19 dm
3
/s (40 scfm), set
the drip rate at 4 drops per minute. Turn knob
counterclockwise to increase and clockwise to decrease
the drip rate. The oil feed setting can be locked by
pushing the lock ring down, this must be released before
adjustment by pulling up.
4. Micro-Fog Lubricators - Oil drip rate is adjusted by the
red knob above the sight-feed dome, counterclockwise to
increase and clockwise to decrease the drip rate. The rate
changes automatically to compensate for flow variations.
The oil feed setting can be locked by pushing the lock
ring down, this must be released before adjustment by
pulling up.
See Drip Rate Chart. Turn knob counterclockwise to
increase and clockwise to decrease the drip rate.

5. 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.
DISASSEMBLY
1. Shut off inlet pressure. Reduce pressure in inlet and
outlet lines to zero. Loosen fill plug (1).
2. Remove reservoir - push into body and turn
counterclockwise.
3. Disassemble in general accordance with the item
numbers on exploded view. Do not remove the manual
drain unless replacement is necessary. Remove and
replace drain assembly only if drain malfunctions. Do not
remove syphon tube (53). Remove and replace items 54
through 59 only if lubricator malfunctions.
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 o-rings, the portion of the manual drain body
(19, 33) that contacts the bowl, and the hole in the
manual drain body that accommodates the stem of drain
valve (20, 34) with o-ring grease.
2. Assemble lubricator as shown on exploded view.
3. Assemble the 1 litre (1 quart) liquid indicator parts (69
through 74) to reservoir. Apply a 0,9 to 1,8 kg (2 to 4
pound) clamping force to upper and lower sight glass
brackets (70). Tighten screws (69).
3. Torque Table N-m (Inch-Pounds)
3 (Dome) 2,3 to 2,8 (20 to 25)
43 (Screw) 1,7 to 2,3 (15 to 20)
55 (Screw) 1,1 to 1,6 (10 to 14)
69 (Screw) 0,9 to 1,1 (8 to 10)
4. Push reservoir, or reservoir with guard, into body and
turn fully clockwise.

INSTALLATION
1. Install unit vertically in air line -
● vertically (bowl down),
● with air flow in direction of arrow on body,
● upstream of cycling valves
● as close as possible to the device being lubricated,
● Oil-Fog Models - Not more than 5,2m (15 feet) from
the device being lubricated, and at the same height or
higher than the device.
2. Before assembling the basic unit into the yoke the port
seal o-rings should be lightly smeared with o-ring
grease.
3. Locate clamp ring under lugs on top of yoke, offer basic
unit into yoke with directional arrows correctly aligned
(an interference fit prevents assembly if misaligned)
before engaging and fully tightening the clamp ring.
4. Turn bowl or bowl guard fully clockwise into body before
pressurizing. Lock symbols on body and bowl guards
must align.

Installation & Maintenance Instructions
RECOMMENDED LUBRICANTS
Fill reservoir with a good quality, light, misting type oil
for comp
ressed air tools. See our publication
N/AL.8.900.935. Fill to maximum fill line on transparent
voirs. Oil level must always be visible in lens on metal
reser
reservoirs. Do not overfill.
FILL RESERVOIR (OIL-FOG LUBRICATORS)
Remove fill plug (1), add oil, and reinstall fill plug. Fill
plug can be removed and oil added without shutting off air
pressure to the lubricator
FILL RESERVOIR (MICRO-FOG LUBRICATORS)
Shut off inlet air pressure and reduce pressure in
reservoir to zero. Remove fill plug (1), add oil, and reinstall
fill plug. Do not remove the fill plug when the reservoir is
pressurized, as oil will blow out the fill plug hole.

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 bowls can be damaged and
possibly burst if exposed to such substances as certain
solvents, strong alkalies, compressor oils containing esterbased additives or synthetic oils. Fumes of these
substances in contact with the polycarbonate bowl,
externally or internally, can also result in damage. Clean
with warm water only.
Use metal bowl in applications where a plastic bowl
might be exposed to substances that are incompatible with
polycarbonate.
Before using these products with fluids other than air, for
non industrial applications, or for life-support systems
consult IMI Precision Engineering.
