Installation & Maintenance

Instructions

ADJUSTMENT

1. Turn on system pressure.

2. Adjust lubricator drip rate under a steady flow condition. Air flow should be at the rate the lubricator will be used. Monitor drip rate thru sight feed dome (1).

3. Determine the air flow (scfm) thru the lubricator. Refer to the shaded area in the Drip Rate Chart and determine the drip rate corresponding to the air flow. Select an initial drip rate toward the rich side of the shaded area for inlet pressure less than 6,2 bar (90 psig), or toward the lean side for inlet pressure more than 6,2 bar (90 psig). Turn adjustment counterclockwise to increase and clockwise to decrease the drip rate. Total travel of adjustment (1) 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.

DISASSEMBLY

1. Shut off inlet pressure. Reduce pressure in inlet and outlet lines to zero. Loosen fill plug. Lubricator may be disassembled without removal from the air line.

2. Remove reservoir:

1-Quart Reservoir: Turn reservoir (40) counterclockwise and remove from adapter (28). All Other Reservoirs: Remove screws (6, 7) and separate reservoir from body.

3. Disassemble in general accordance with the item numbers on exploded view. Unscrew siphon tube assembly (10), taking care not to lose check ball (11). Do not remove siphon tube from fitting. Charge valve (9) is not used with 2 and 5-gallon reservoirs. Do not remove drain (30, 31, 32) unless replacement is necessary. Remove and replace only if it malfunctions.

4. Disassembly of the reservoirs is not normally required.

CLEANING

1. Clean plastic reservoir and sight feed dome 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.

* Current 1-quart reservoir models (Model 10-028-545)

use liquid level lens kit 2273-22. Early 1-quart reservoir models (Model 10-028-045) are identical in appearance to the 2-quart reservoir and use liquid level lens kit 2272-02.

INSTALLATION

1. Shut-off air pressure. Support weight of lubricator with 2 and 5 gallon reservoirs on shelf, floor, etc. 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,

NOTE

Oil-Fog lubricators are generally installed no more than 5,2m (15 feet) from the device being lubricated. The 10-028 lubricator, however, will perform satisfactorily at distances greater than 5,2m (15 feet) if installed at a location sufficiently higher than the device being lubricated, and the pipe network does not contain low spots or complex bends.

2. Connect piping to proper ports using pipe thread sealant on male threads only. Do not allow sealant to enter interior of unit.

RECOMMENDED LUBRICANTS

Use a good quality, non-detergent, light, misting type oil for compressed air tools. See Norgren publication N/AL.8.900.935.

FILL RESERVOIR

Shut off inlet air pressure and reduce pressure in reservoir to zero. Remove fill plug, add oil, and reinstall fill plug. Fill to maximum fill line on transparent reservoir. Oil level must always be visible in liquid level lens on metal reservoir. DO

NOT OVERFILL. Do not remove the fill plug on lubricators with 2 and 5-gallon reservoirs when the reservoir is pressurized, as oil will blow out the fill plug hole. The fill

plug on lubricators with smaller reservoirs may be removed and the reservoir refilled when the reservoir is pressurized.

Installation & Maintenance

Instructions

ASSEMBLY

1. Lubricate o-rings with o-ring grease.

2 If the 1/4 turn manual drain (30, 31, 32 ) was removed,

lubricate the portion of the drain body (30) that contacts the bowl, and the hole in the manual drain body that accommodates the stem of drain valve (31) with o-ring grease. Press body (30) thru hole from inside of bowl. Place retainer o-ring (32) over body (30) and position in groove. Press drain valve (31) thru hole in body (30).

3. Assemble the liquid indicator parts (33 thru 38) to bowl. Apply a 0,9 to 1,8 kg (2 to 4 pound) clamping force to upper and lower brackets (34) to pull brackets together. Tighten screws (33) to 0,9 to 1,1 N-m (8 to 10 inchpounds).

4. Assemble lubricator as shown on exploded view. Pay particular attention to the following:

● Tighten sight feed dome (1) to 2,3 to 2,8 N-m (20 to

25 inch-pounds).

● Apply increasing torque to the six reservoir adapter

screws (6, 7) in a crisscross pattern. Apply final torque of 2,26 to 3,39 N-m (20 to 30 inch-pounds).

● Turn bowl (40) into adapter (28) until arrowhead on

bowl is aligned with or to the right of slot in adapter.

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.

The polycarbonate sight feed dome and reservoir 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 sight feed dome and reservoir, externally or internally, can also result in damage. Clean with warm water only

Use pyrex sight feed dome and metal reservoir in applications where the lubricator 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.
