Section 4: Purging Air After Adding or Replacing a Master Divider Valve Module
Steps 1-7, refer to FIG. 9.
1. Install the new or replacement module into the mas-
ter divider valve assembly. Also connect the tubing
or hoses to the appropriate secondary divider
valve(s) or lubrication point(s) if the new/replace-
ment module is a base section.
2. Do not completely tighten the connection(s) at the
secondary divider valve’s inlet or at lubrication
points.
3. Disconnect and remove the line from the pump at
the inlet of the master divider valve.
4. Attach a hand pump filled with clean, filtered lubri-
cant to the inlet port on the master divider valve.
5. Operate the hand pump until air-free lubricant is
observed flowing from each secondary valve’s lube
inlet connector and/or each lubrication point’s con-
nector.
6. Tighten the fitting at the secondary valve inlet or at
the lubrication port while lubricant is still flowing.
7. Remove the hand pump and reconnect the system
pump to the inlet of the master divider valve.
The system is now ready for operation.
