THE LEADER IN OIL MIST TECHNOLOGY
77740201 REV 4 January 17, 2019
Installation
Install the Model “VM” on a wall or column in an upright position using the four mounting holes on the unit reservoir. The oil level gauge
should be in full view, and the oil fill port, located on the top of the mist head, must be accessible.
Connect the oil mist distribution system to the 1" NPTF oil mist outlet located on the right side of the mist head. Connect a clean, dry
compressed air supply to the left side of the oil mist unit. For units furnished with the
LubriMist
®
integral air filter/regulator, maximum supply
air pressure is 125 PSIG. If customer provided air controls are installed, they should be capable of varying and controlling the supply air
pressure to the mist head from 10 to 50 PSIG.
It is recommended that a mist pressure gauge, Part No. U-902-S (purchased separately), be installed in the oil mist header. The mist
pressure gauge should be located so that it can be easily read and monitored as adjustments to the integral air filter/regulator are made
during start-up.
This LubriMist
®
Oil Mist Generator has been designed and factory tested with LubriMist
®
Synthetic Oil (LSO). LSC recommends LSO for
this oil mist generator in order to insure optimum performance.
Electrical connections should be made by a qualified electrician. All conduit connections are 1/2" NPTF. See "Electrical" for electric
component configuration and wiring diagrams. The low-level alarm switch can be used for local or remote annunciation. (Alarm
annunciation is provided by the purchaser.) The air solenoid valve should be installed with a local user provided disconnect.
Start-Up
Prior to start-up, recheck all connections and insure that all fittings are tight and electrical connections are properly made. Insure that the
oil mist distribution system, reclassifiers, and application point connections, vents and drains are properly installed.
If a mist pressure gauge has been installed in the oil mist header, calculation of the system flow rate is not necessary for start-up. If a mist
pressure gauge is not installed use Figure 2 to determine the total system flow rate.
This flow rate is necessary to determine the proper regulated air pressure setting in Step No. 3 below:

To Start the LubriMist
®
Model "VM"
1. Remove the oil cap, located on top of the mist head, and fill the oil reservoir approximately 75% full, taking care not to exceed the
"high" level mark on the oil sight gauge. Oil selection should be made based on lubrication and viscosity requirement dictated by the
machinery components being serviced. DO NOT USE MOTOR OIL or any other oil that has viscosity improving additives. Replace the
oil fill cap.
2. Turn on the air supply to the integral air filter/regulator. For units equipped with an air solenoid valve, turn on the electrical power to
the air solenoid valve.
3. Adjust the regulated air pressure:
a. If a mist pressure gauge has been installed in the oil mist header, adjust the integral air filter/regulator until the desired mist
pressure reading is achieved. Mist pressure setting should be set at 20" H
2
O for "CONDENSING" and "SPRAY" type systems.
b. If a mist pressure gauge has not been installed, refer to the total SCFM flow rate determined in Figure 2. Using Figure 5, locate
the proper flow curve for size unit installed. Knowing the SCFM requirement, draw a horizontal line from the SCFM requirement
until it intersects the line for the correct mist head size. Drop vertically down and read the regulated air supply pressure. Adjust
the integral air filter/ regulator (Item 7, Fig. 3) until the air pressure gauge (Item 6, Fig. 3) reads this setting. (Minimum regulated
air pressure setting is 10 PSIG).
