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.
RECOMMENDED LUBRICANTS
Fill reservoir with a good quality, light, misting type oil for
compressed air tools. See our publication N/AL.8.900.935.
Fill to maximum ill line on transparent reservoirs. Oil level
must always be visible in lens on metal reservoirs. Do not
overill.
FILL RESERVOIR OILFOG LUBRICATORS
Remove ill plug (1), add oil, and reinstall ill 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 ill plug (1), add oil, and reinstall ill plug. Do
not remove the ill plug when the reservoir is
pressurized, as oil will blow out the ill plug hole.
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 dm3/s (10 scfm). For example, if
the average flow is 19 dm3/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, counterclock-
wise 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 adjust-
ment 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 counterc-
lockwise.
3. Disassemble in general accordance with the item num-
bers 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.

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)

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 luids other than air, for
non industrial applications, or for life-support systems
consult IMI Precision Engineering.
