AIR CONNECTIONS
NOTE
For quick response, Nexen recommends a quick exhaust valve and short air lines between the Control Valve and the FMCE.
Align the air inlet port to a down position to allow condensation to drain out of the air chamber of the FMCE.
LUBRICATION
NOTE
Pneumatically actuated devices require clean, pressure regulated, and lubricated air for maximum performance and long
life. The most effective and economical way to lubricate the FMCE is with an Air Line Lubricator, which injects oil into the
pressurized air, forcing an oil mist into the air chamber.
Locate the lubricator above and within ten feet of the FMCE, and use a low viscosity oil such as SAE-10.
Synthetic lubricants are not recommended.
LUBRICATOR DRIP RATE SETTINGS
NOTE
These settings are for Nexen supplied lubricators. If you are not using a Nexen lubricator, calibration must replicate the
following procedure.
1. Close and disconnect the air line from the unit.
2. Turn the Lubricator Adjustment Knob clockwise three com-
plete turns.
3. Open the air line.
4. Close the air line to the unit when a drop of oil forms in the
Lubricator Sight Gage.
5. Connect the air line to the unit.
6. Turn the Lubricator Adjustment Knob counterclockwise until
closed.
7. Turn the Lubricator Adjustment Knob clockwise one-third
turn.
8. Open the air line to the unit.
