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 master

divider valve assembly. Also connect the tubing or hoses

to the appropriate secondary divider valve(s) or lubrica-

tion point(s) if the new/replacement module is a base sec-

tion.

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 lubricant 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 connector.

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.
