How to use Autotrol By Pass - Old Style

Question:

How do you turn the bypass valve on / off ?

What does 61F do?

 

******************

 

The old style Autotrol By Pass Valves use a "push in" method of redirecting the flow.

If you push the knob ( 46F )  IN on the RIGHT ( standing in front of the system ), this will place the valve in "by pass" and cause the knob ( another 46F ) on the left to come out about an inch.

To "restore" flow through the Control Valve and resin tank, you would Push the knob on the Left back IN.

PUSHING the knob can require extreme force. A hard "push" with your fist, or a "tap" with a hammer, may be required.

 

Sometimes engaging the By Pass fails to cut off the valve flow to the Control Valve 100%, because the internal oring in the center of the by pass shaft is not sealing 100%. This common failure is the main reason Autotrol now uses a different design ( double shut off - redirecting valves ) for the "new" style By Pass for their Control Valves.

 

The part labeled 61F does not "do anything". And I've never seen this used for anything.
