Removing Air Pockets - ALS
As described in the Problem Prevention section, air pockets may disable the lubrication system
and possibly cause serious damage to equipment components. To prevent damage to your
system, Lubecore™ strongly recommends the use of a Low-Level Sensor. (LLS)
When air pockets are introduced into the ALS accidentally, it is crucial that they are removed as
soon as possible. Follow the steps below to ensure that all air pockets are removed.
Tool Required:
1500 PSI / 100 Bar pressure gauge with ¼”-stem
17mm / 11/16” wrench / socket
9/16” Wrench
1. Ensure that the equipment air tanks are at maximum.
2. Review the total layout of the ALS and locate the system manifolds.
3. Locate the ALS timer and ensure access to the red test button on the front cover of the
timer, the Smart Switch or the magnetic pick up zone on the front label of the trailer timer
enclosure.
4. Remove the plug located below the serial number tag on the pump; install a 1500 PSI /100
Bar pressure gauge.
5. Remove the manifold end plug that is furthest away from the pump and prepare the port to
collect escaping lubricant.
6. Initiate a single cycle and observe the grease flow from the open port, repeat until no air
bubbles, spurting or spraying is being observed at the manifold that is open. Grease should
be seen flowing in a consistent release from the manifold.
7. When all air has been purged from that particular section of mainline; With the pump under
air-pressure, reinstall the manifold end plug,
8. Repeat procedures 5 through 7 with the next manifold. (Note: cycle pneumatic pump 4 times
for every 10 meters, (30 feet) of mainline length.)
System has now been bled of air-pockets and all plugs have been reinstalled and tight,
Lastly initiate a manual test cycle. Pressure should hold between 900-1100 PSI / 60-76
Bar and not drop. After holding pressure for a few minutes, the system will deactivate and
depressurize.
If pressure is not reached, please check equipment air tank pressure; numerous test cycles
could have depleted air pressure to below the required level for the equipment. If pressure is not
reached review error recovery section of this manual or contact Lubecore for assistance.
Note: Principles for purging air from an automated lubrication system are the same whether the
ALS is pneumatic, electric, hydraulic or hybrid. The manifolds, timer, and pump must be
found and the system must be able to be activated to purge air from the ALS.
