L50 Injection Lubricator - Parker

Remote Auto-Fill Device 2L301B
7. Connect the hydraulic supply line to the bottom of the Auto-Fill
Device.
8. Remove the manual fill plug and add enough oil to reach the
bottom of the float.
9. Turn on air supply and check for external leakage at the top
and bottom of the bowl assembly.
Note: Air may leak out the bottom of the fill device unless its
interior has been “wetted” with oil from step 8. Also, oil may
automaticlly drain out before air pressure is applied, hence
the oil line connection at step 7 is important.
10. Unit is now ready for operation.

Installation
1. Connect oil supply feeder line to the Remote Auto Fill 1/8-27
NPT female thread fitting. Flexible tubing is recommended
between lubricator and oil supply main header line. Also attach
a shut-off valve, which may be necessary should servicing be
required.
!
CAUTION: Rigid pipe should be avoided to prevent possible
lubricator bowl damage due to stress and machine vibration.
2. Connect opposite end of flexible tube feeder line to main oil
supply line.
NOTE: Oil supply source and main supply line should be pressurized
at least 20 PSI above system air pressure, and may be
up to 300 PSIG maximum. Oil supply line should be pressurized
for 2 to 15 minutes, one or more times a day. Frequency should
be based on maintaining oil in lubricator at its highest level.
NOTE: Oil supply pressure should be shut off after the refill
period is completed. Lubricators will not permit additional oil
to be admitted until supply system pressure has first dropped
below air system pressure.
